Objectives: Diode laser represents a practical clinical strategy for treating gingival hyperpigmentation. However, its effectiveness remains controversial. The aim of this meta-analysis was to evaluate the quantitative effects of diode laser therapy on gingival hyperpigmentation. Method and materials: PubMed, Embase, Web of Science, and Cochrane Library were systematically searched for the use of diode laser in gingival hyperpigmenta-tion. The primary outcomes assessed were the Dummett-Gupta Oral Pigmentation Index (DOPI), visual analog scale pain scores, and the Wound Healing Index (WHI) for overall evaluation. The I2 index was calculated to identify heterogeneity, and sensitivity analyses were performed to identify sources of heterogeneity. Funnel plots and the Egger test were utilized to evaluate publication bias. Results: Thirteen randomized controlled trials involving a total of 233 participants were included in the study. The analysis demonstrated that diode laser had a significant effect on DOPI (standard mean difference [SMD] = -0.245, 95% CI -0.451 to -0.040, P= .019) and pain (SMD = -0.809, 95% CI -1.332 to -0.285, P= .002), with no significant effect on WHI (SMD = -0.224, 95% CI -1.100 to 0.653, P= .617). Despite the significant heterogeneity in VAS and WHI indicated by the I2 index statistic, the sensitivity analyses' results demonstrated the main findings' reliability. While no significant publication bias was detected for DOPI and WHI, the pain results exhibited notable publication bias. Conclusion: The study demonstrated that diode laser prolongs gingival repigmentation time and reduces pain compared to other treatments. However, efficacy in wound healing was not significantly affected. [ABSTRACT FROM AUTHOR]

Context: Foot/ankle pain is common among runners. Inadequate management of runners with foot/ankle pain can lead to lost training time, competition removal, and other activity limitations. Neurodynamics, which refers to the integrated biomechanical, physiological, and structural function of the nervous system during movement, can be overlooked in patients with foot/ankle pain. Although a link between the cervical spine, neurodynamics, and upper quarter pain has been studied, less is known about the relationship between the lumbar spine and lower quarter. This case series describes the successful management of 3 runners with foot/ankle pain. Case Presentations: Three female runners (ages 23, 24, and 45 y) presented to physical therapy with foot/ankle pain and difficulty running. Each patient had positive examination findings with local foot/ankle testing. A comprehensive lumbar spine examination demonstrated impairments in range of motion and joint mobility that were hypothesized to be contributing. Positive lower quarter neurodynamic tests were also found. Management and Outcomes: All patients were treated with nonthrust lumbar spine mobilization and lower quarter neural tissue mobilization. Changes in the Patient-Specific Functional Scale, Numerical Pain Rating Scale, Lower Extremity Functional Scale, and Global Rating of Change occurred after intervention targeting the lumbar spine and lower-extremity neurodynamics in all patients. Conclusions: This case series demonstrates the importance of including a thorough lumbar spine examination and neurodynamic testing to identify appropriate interventions while managing patients with foot/ankle pain, even when patients have signs indicative of local ankle/foot pathology. These examination procedures should be performed particularly when a patient is not responding to management targeting local foot/ankle structures. [ABSTRACT FROM AUTHOR]

Objective: This review aimed to examine differences in outcomes with the use of intra-articular hyaluronic acid vs corticosteroids after temporomandibular joint arthrocentesis. Method and materials: Studies were searched on PubMed, Embase, Web of Science, and Google Scholar up to 15th January 2024. Randomized controlled trials comparing hyaluronic acid with corticosteroids after TMJ arthrocentesis were included. The outcomes were pain and maximal mouth opening. Results: Ten articles corresponding to nine randomized clinical trials were included. There was no statistically significant difference in pain scores at 1 week (mean difference [MD] -0.30, 95% CI -1.25 to 0.65, I2 = 0%), 1 month (MD -0.55, 95% CI -1.23 to 0.13, I2 = 0%), and 6 months (MD -0.57, 95% CI -2.10 to 0.96, I2 = 58%) between the two groups. However, pain scores were found to be significantly lower in the hyaluronic acid group at 3 months (MD -1.07, 95% CI -1.84 to -0.31, I2 = 0%). No statistically significant difference was noted in maximal mouth opening at 1 week (MD 0.78, 95% CI -1.79 to 3.35, I2 = 0%), 1 month (MD 0.32, 95% CI -1.83 to 2.46, I2 = 0%), and 3 months (MD -0.41, 95% CI -3.90 to 3.07, I2 = 0%) between the two groups. Descriptive analysis for studies not included in the meta-analysis also presented similar results. Conclusions: Low-quality evidence suggests that both intra-articular hyaluronic acid and corticosteroids have similar efficacy in improving pain scores and maximal mouth opening after temporomandibular joint arthrocentesis.

Objectives: This randomized clinical trial compared the effectiveness of music and informative videos as distraction tools to reduce the anxiety of patients during root canal treatment and retreatment. Method and materials: A total of 90 patients were enrolled in the study. The patients were randomly allocated to three groups: Group 1 listened to music during the treatment (n = 30), Group 2 watched an informative preoperative video (n = 30), and a control group underwent treatment without a distraction method (n = 30). Prior to treatment, the Corah Dental Anxiety Scale (CDAS) and a visual analog scale for pain were used to assess anxiety and preoperative pain. Systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation were recorded before the intervention (T1), after the local anesthetic (T2), following pulp extirpation or removal of root fillings (T3), and immediately following rubber dam removal (T4). One-way ANOVA, followed by post-hoc Bonferroni tests for multiple comparisons, were used to compare mean values of systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation among the groups. A P value of 5% was considered as significant. Results: Listening to music reduced systolic blood pressure, heart rate (P < .001), and diastolic blood pressure (P = .003) in patients undergoing root canal treatment and retreatment at T4 compared to the baseline (T1). Music (P < .001) and informative video (P = .003) groups had significantly lower postoperative visual analog scale pain scores. Conclusion: Listening to music during root canal treatment and retreatment reduced anxiety levels in patients compared to informative preoperative videos and no distraction technique.

Measures of life outlook in older adults have been investigated in connection to pain, as both pain management and outlook are important factors of successful aging. We hypothesized that higher pain is associated with lower optimism among community-dwelling older adults. We utilized data from the UC San Diego Successful Aging Evaluation (SAGE), a prospective longitudinal cohort study initiated in 2010, to evaluate the relationship between pain and optimism in 378 community-dwelling adults aged ≥50 years. We used the revised Life Orientation Test (LOT-R) to measure optimism and three pain subscales-PROMIS Pain Interference, PROMIS Pain Intensity, and MOS 36-Item Short-Form Health Survey (SF-36)-as pain measures. Regression analyses reveal negative relationships between pain and optimism for all three pain scales, with regression coefficients of -0.277 (p

BackgroundPain is ubiquitous, yet understudied. The objective of this study was to analyze inequities in pain assessment and management for hospitalized older adults focusing on demographic and geriatric-related variables.MethodsThis was a retrospective cohort study from January 2013 through September 2021 of all adults 65 years or older on the general medicine service at UCSF Medical Center. Primary exposures included (1) demographic variables including race/ethnicity and limited English proficiency (LEP) status and (2) geriatric-related variables including age, dementia or mild cognitive impairment diagnosis, hearing or visual impairment, end-of-life care, and geriatrics consult involvement. Primary outcomes included (1) adjusted odds of numeric pain assessment versus other assessments and (2) adjusted opioids administered, measured by morphine milligram equivalents (MME).ResultsA total of 15,809 patients were included across 27,857 hospitalizations with 1,378,215 pain assessments, with a mean age of 77.8 years old. Patients were 47.4% White, 26.3% with LEP, 49.6% male, and 50.4% female. Asian (OR 0.75, 95% CI 0.70-0.80), Latinx (OR 0.90, 95% CI 0.83-0.99), and Native Hawaiian or Pacific Islander (OR 0.77, 95% CI 0.64-0.93) patients had lower odds of a numeric assessment, compared with White patients. Patients with LEP (OR 0.70, 95% CI 0.66-0.74) had lower odds of a numeric assessment, compared with English-speaking patients. Patients with dementia, hearing impairment, patients 75+, and at end-of-life were all less likely to receive a numeric assessment. Compared with White patients (86 MME, 95% CI 77-96), Asian patients (55 MME, 95% CI 46-65) received fewer opioids. Patients with LEP, dementia, hearing impairment and those 75+ years old also received significantly fewer opioids.ConclusionOlder, hospitalized, general medicine patients from minoritized groups and with geriatric-related conditions are uniquely vulnerable to inequitable pain assessment and management. These findings raise concerns for pain underassessment and undertreatment.

Postural assessments of the lumbar spine lack valuable information about its properties. The purpose of this study was to assess neutral zone (NZ) characteristics via in vivo lumbar spine passive stiffness and relate NZ characteristics to standing lumbar lordosis. A comparison was made between those that develop low back pain during prolonged standing (pain developers) and those that do not (nonpain developers). Twenty-two participants with known pain status stood on level ground, and median lumbar lordosis angle was calculated. Participants were then placed in a near-frictionless jig to characterize their passive stiffness curve and location of their NZ. Overall, both pain developers and nonpain developers stood with a lumbar lordosis angle that was more extended than their NZ boundary. Pain developers stood slightly more extended (in comparison to nonpain developers) and had a lower moment corresponding to the location of their extension NZ boundary. Overall, in comparison to nonpain developers, pain developers displayed a lower moment corresponding to the location of their extension NZ boundary which could correspond to greater laxity in the lumbar spine. This may indicate why pain developers have a tendency to stand further beyond their NZ with greater muscle co-contraction. [ABSTRACT FROM AUTHOR]

Back pain lifetime incidence is 60%–70%, while 12%–20% of older women have vertebral fractures (VFs), often with back pain. We aimed to provide objective evidence, currently lacking, regarding whether back pain and VFs affect physical activity (PA). We recruited 69 women with recent back pain (age 74.5 ± 5.4 years). Low- (0.5 < g < 1.0), medium- (1.0 ≤ g < 1.5), and high-impact (g ≥ 1.5) PA and walking time were measured (100 Hz for 7 days, hip-worn accelerometer). Linear mixed-effects models assessed associations between self-reported pain and PA, and group differences (VFs from spine radiographs/no-VF) in PA. Higher daily pain was associated with reduced low (β = −0.12, 95% confidence interval, [−0.22, −0.03], p =.013) and medium-impact PA (β = −0.11, 95% confidence interval, [−0.21, −0.01], p =.041), but not high-impact PA or walking time (p >.11). VFs were not associated with PA (all p >.2). Higher daily pain levels but not VFs were associated with reduced low- and medium-impact PA, which could increase sarcopenia and falls risk in older women with back pain. [ABSTRACT FROM AUTHOR]

Context: Lateral epicondylopathy (LE) is a common overuse injury affecting elbow, wrist, and hand function. It is characterized by weakness and pain in the muscles and tendons of the forearm responsible for the extension of your wrist and fingers. Trigger point dry needling is a technique reported to be beneficial in managing pain and dysfunction after LE diagnosis. LE is also commonly treated with conservative treatment, such as joint and soft tissue mobilization, self-care home programs, and anti-inflammatory use. We explored a different dry needling approach consisting of in situ dry needling with electric stimulation combined with targeted therapeutic exercise to treat LE in 3 cases. Case Presentation: Three patients were referred for dry needling once a week for 6 weeks and home-based exercise therapy for LE. They were clinically evaluated using grip strength, a visual analog scale to assess pain, and Patient-Rated Tennis Elbow Evaluation Test scores. These were measured at 4 time points (weeks 0, 2, 4, and 6). Management and Outcomes: The dry needling intervention incorporated 8 locations in the upper-extremity with 2 electric stimulation channels. The patients had reduced pain as measured by a visual analog scale, increased function as measured by the Patient-Rated Tennis Elbow Evaluation Test, and increased grip strength over 6 weeks. Conclusions: This case series illustrates the use of dry needling and a home exercise program to provide a favorable outcome in a patient with LE. Patients had an 80% to 100% reduction in pain and similar improvements in function that were significantly beyond the minimum clinically important difference. This dry needling approach is a safe and effective treatment of LE in the short term. [ABSTRACT FROM AUTHOR]

Objectives: This study examined the impact of injectable plateletrich fibrin (iPRF) and concentrated growth factor on postoperative pain, edema, trismus, and quality of life in impacted mandibular third molar surgery. The primary aim of this study was to minimize common sequelae following third molar surgery by using iPRF and concentrated growth factor. The secondary objective was to compare the postoperative effects of these products. Method and materials: This study represents a single-center, randomized prospective clinical trial conducted at the Ordu University Faculty of Dentistry. It involved patients who underwent third molar surgery for various reasons between July and October 2022. The predictor variables were the use of concentrated growth factor and i-PRF. They were categorized as concentrated growth factor, i-PRF, and control groups. The outcome variables include pain levels and analgesic consumption measured on a visual analog scale, distances between predetermined anatomical points, maximum mouth opening capacity, and data from the postoperative symptom severity (PoSSe) scale. Some statistical tests were performed with a 95% confidence interval, which was considered significant. Results: Total analgesic use was notably lower in the concentrated growth factor group (P = .044). Concentrated growth factor and iPRF outperformed the control group in all edema measurements by postoperative day 7 (tragus–pogonion, lateral canthus–angulus, tragus–commissura; P < .05). Concentrated growth factor significantly reduced trismus on days 2 and 7. Quality of life was notably higher in the concentrated growth factor group than in the control group (P = .026), although iPRF group differences were not significant. Conclusion: The results indicate that concentrated growth factor has a limited impact on postoperative pain, but significantly reduces edema, trismus, and enhances quality of life. The iPRF group experienced positive effects on pain, edema, and trismus, although the statistically significant differences observed with concentrated growth factor highlight its potential for use instead of iPRF after third molar surgery. An increased sample size is essential for more comprehensive results [ABSTRACT FROM AUTHOR]

BACKGROUND: Percutaneous auricular nerve stimulation (neuromodulation) involves implanting electrodes around the ear and administering an electric current. A device is currently available within the USA cleared to treat symptoms from opioid withdrawal, and multiple reports suggest a possible postoperative analgesic effect. The current randomized controlled pilot study was undertaken to (1) determine the feasibility and optimize the protocol for a subsequent definitive clinical trial; and (2) estimate the treatment effect of auricular neuromodulation on postoperative pain and opioid consumption following two ambulatory surgical procedures. METHODS: Within the recovery room following cholecystectomy or hernia repair, an auricular neuromodulation device (NSS-2 Bridge, Masimo, Irvine, California, USA) was applied. Participants were randomized to 5 days of either electrical stimulation or sham in a double-blinded fashion. RESULTS: In the first 5 days, the median (IQR) pain level for active stimulation (n=15) was 0.6 (0.3-2.4) vs 2.6 (1.1-3.7) for the sham group (n=15) (p=0.041). Concurrently, the median oxycodone use for the active stimulation group was 0 mg (0-1), compared with 0 mg (0-3) for the sham group (p=0.524). Regarding the highest pain level experienced over the entire 8-day study period, only one participant (7%) who received active stimulation experienced severe pain, versus seven (47%) in those given sham (p=0.031). CONCLUSIONS: Percutaneous auricular neuromodulation reduced pain scores but not opioid requirements during the initial week after cholecystectomy and hernia repair. Given the ease of application as well as a lack of systemic side effects and reported complications, a definitive clinical trial appears warranted. TRIAL REGISTRATION NUMBER: NCT05521516.

OBJECTIVE: To evaluate the role of psychosocial well-being on perioperative pain and opioid use among patients with cleft lip and palate (CLP) undergoing alveolar bone grafting (ABG). DESIGN: Retrospective review. SETTING: Tertiary level craniofacial clinic. PARTICIPANTS: 34 patients with CLP (median age: 11.7 years), including 25 (73.5%) unilateral CLP and 9 (26.5%) bilateral CLP, who underwent ABG from 2015 to 2022. INTERVENTIONS: ABG using iliac crest bone graft. Patients were prospectively administered four patient-reported psychosocial instruments from the Patient-Reported Outcomes Measurement Information System. MAIN OUTCOME MEASURES: Perioperative opioid use in morphine equivalent dosage/kilogram, patient-reported pain scores, and length of hospital stay after ABG. RESULTS: Patient-reported anxiety (r = 0.41, p = 0.02) and depressive symptoms (r = 0.35, p = 0.04) correlated to higher perioperative opioid usage. Multivariable regression models including psychosocial scores, total acetaminophen usage, length of surgery, and other simultaneous surgeries were developed for total opioid usage, patient-reported pain, and length of hospital stay. Patient-reported anxiety was independently predictive of higher perioperative opioid use (β=0.36, p = 0.01) and higher pain scores (β=0.39, p = 0.02), but not length of hospital stay. CONCLUSIONS: We identified an association for patient-reported anxiety and perioperative opioid use and pain in a CLP cohort undergoing ABG. Future considerations in preoperative patient and family consultation may be indicated in patients self-reporting higher anxiety in an effort to minimize perioperative opioid usage.

AbstractPain anticipation during conditions of uncertainty can unveil intrinsic biases, and understanding these biases can guide pain treatment interventions. This study used machine learning and functional magnetic resonance imaging to predict anticipatory responses in a pain anticipation experiment. One hundred forty-seven participants that included healthy controls (n = 57) and individuals with current and/or past mental health diagnosis (n = 90) received cues indicating upcoming pain stimuli: 2 cues predicted high and low temperatures, while a third cue introduced uncertainty. Accurate differentiation of neural patterns associated with specific anticipatory conditions was observed, involving activation in the anterior short gyrus of the insula and the nucleus accumbens. Three distinct response profiles emerged: subjects with a negative bias towards high pain anticipation, those with a positive bias towards low pain anticipation, and individuals whose predictions during uncertainty were unbiased. These profiles remained stable over one year, were consistent across diagnosed psychopathologies, and correlated with cognitive coping styles and underlying insula anatomy. The findings suggest that individualized and stable pain anticipation occurs in uncertain conditions.

BACKGROUND: Paediatric laceration repair procedures are common in the ED; however, post-discharge recovery remains understudied. Perioperative research demonstrates that children exhibit maladaptive behavioural changes following stressful and painful medical procedures. This study examined post-discharge recovery following paediatric laceration repair in the ED. METHODS: This prospective observational study included a convenience sample of 173 children 2-12 years old undergoing laceration repair in a paediatric ED in Orange, California, USA between April 2022 and August 2023. Demographics, laceration and treatment data (eg, anxiolytic medication), and caregiver-reported child pre-procedural and procedural pain (Numerical Rating Scale (NRS)) were collected. On days 1, 3, 7 and 14 post-discharge, caregivers reported childrens pain and new-onset maladaptive behavioural changes (eg, separation anxiety) via the Post Hospitalization Behavior Questionnaire for Ambulatory Surgery. Univariate and logistic regression analyses were conducted to identify variables associated with the incidence of post-discharge maladaptive behavioural change. RESULTS: Post-discharge maladaptive behavioural changes were reported in 43.9% (n=69) of children. At 1 week post-discharge, approximately 20% (n=27) of children exhibited maladaptive behavioural changes and 10% (n=13) displayed behavioural changes 2 weeks post-discharge. Mild levels of pain (NRS ≥2) were reported in 46.7% (n=70) of children on post-discharge day 1, 10.3% (n=14) on day 7 and 3.1% (n=4) on day 14. An extremity laceration (p=0.029), pre-procedural midazolam (p=0.020), longer length of stay (p=0.043) and post-discharge pain on day 1 (p

Chronic neuropathic pain can result from nervous system injury and can persist in the absence of external stimuli. Although ongoing pain characterizes the disorder, in many individuals, the intensity of this ongoing pain fluctuates dramatically. Previously, it was identified that functional magnetic resonance imaging signal covariations between the midbrain periaqueductal gray (PAG) matter, rostral ventromedial medulla (RVM), and spinal trigeminal nucleus are associated with moment-to-moment fluctuations in pain intensity in individuals with painful trigeminal neuropathy (PTN). Since this brainstem circuit is modulated by higher brain input, we sought to determine which cortical sites might be influencing this brainstem network during spontaneous fluctuations in pain intensity. Over 12 min, we recorded the ongoing pain intensity in 24 PTN participants and classified them as fluctuating (n = 13) or stable (n = 11). Using a PAG seed, we identified connections between the PAG and emotional-affective sites such as the hippocampal and posterior cingulate cortices, the sensory-discriminative posterior insula, and cognitive-affective sites such as the dorsolateral prefrontal (dlPFC) and subgenual anterior cingulate cortices that were altered dependent on spontaneous high and low pain intensity. Additionally, sliding-window functional connectivity analysis revealed that the dlPFC-PAG connection anticorrelated with perceived pain intensity over the entire 12 min period. These findings reveal cortical systems underlying moment-to-moment changes in perceived pain in PTN, which likely cause dysregulation in the brainstem circuits previously identified, and consequently alter the appraisal of pain across time.

Context: Wheelchair Power Soccer (WPS) is the only team sport that allows the participation of people with severe physical disabilities who require the daily use of motorized wheelchairs. These individuals may live with chronic pain due to the characteristics of the disabilities and treatments, interfering with their health and limiting their participation in sports. Objectives: To investigate the prevalence of musculoskeletal pain and its relationship with mood in WPS players and to analyze the incidence of traumatic injuries during a championship. Methods: A prospective, longitudinal study was carried out on 30 WPS athletes (93.33% male) with a mean (SD) (range) age of 22.37 (9.79) (47) years. Data collection was performed during a South American WPS Championship lasting 3 days, with: investigation of the presence of musculoskeletal pain and mood through a questionnaire; investigation of the occurrence of traumatic injuries through match observation; and confirmation of the occurrence of traumatic injuries through access to medical department records. Results: About 30% (n = 9/30) of the sample presented some pain on the day of evaluation, with an intensity of 5.67 (3.35) (10) points on the visual analog scale. The most common regions of pain were the lower back (13.3%, n = 4/30), thoracic (10%; n = 3/30), and cervical (10%; n = 3/30) areas of the spine. A total of 46.7% (n = 14/30) reported pain in the month before data collection but of less intensity (2.56 [4] [10] points), the most common regions being the lower limbs (20%; n = 6/30) and cervical spine (20%; n = 6/30). Among the between-group comparisons (ie, participants with pain vs without pain), no relationship was observed between mood state and pain. No traumatic injuries were identified during the competition. Conclusion: The presence of musculoskeletal pain was common in WPS players, but it was not related to mood. As no traumatic injuries were observed during the championship, this modality seems to be safe for people with physical disabilities in general. [ABSTRACT FROM AUTHOR]

Context: Plantar intrinsic foot muscle strength training is difficult to master to a degree sufficient to elicit muscle hypertrophy in most individuals. It is possible that combining neuromuscular electrostimulation (NMES) and blood flow restriction (BFR) can elicit plantar intrinsic foot muscle hypertrophy regardless of the individual's technique. This study aimed to determine the effects of NMES training with BFR on acute muscle swelling in the abductor hallucis. Design: Randomized, controlled, single-blind trial design. Methods: Forty-eight participants were randomly allocated to the NMES + BFR, NMES, or Sham NMES + BFR groups. All participants received abductor hallucis NMES for 15 minutes. Participants in the NMES + BFR and Sham NMES + BFR groups received NMES with BFR. The intensity of NMES was the sensory threshold in the Sham NMES + BFR group. The cross-sectional area of the abductor hallucis was measured pretraining and posttraining using ultrasonography by a single investigator blinded to the participants' allocations. Results: After 15 minutes of training, the cross-sectional area of the abductor hallucis was significantly increased in the NMES + BFR (P<.001) and the Sham NMES + BFR (P = .004) groups. Moreover, the rate of increase was significantly higher in the NMES + BFR group than in the NMES or the Sham NMES + BFR groups (P<.001 and P = . 001, respectively). Conclusions: Since it is possible that the amount of muscle swelling immediately after training correlates with muscle hypertrophy when training is continued, the results of this study suggest that NMES training with BFR is a training method that can be expected to produce plantar intrinsic foot muscle hypertrophy. Further studies are needed to confirm the long-term effects of NMES training with BFR. [ABSTRACT FROM AUTHOR]

Context: Soft tissue mobilization is frequently employed for delayed onset muscle soreness (DOMS) management. Foam roller and percussive massage are 2 popular soft tissue mobilization methods preferred by various professionals. However, their effects on DOMS symptoms are controversial and there are no studies comparing these 2 methods. The aim of the present study was to compare the acute effects of soft tissue mobilization with a foam roller or a percussive massage device on DOMS in young male recreational athletes. Design: A parallel, single-blinded, randomized controlled trial. Methods: Thirty-six participants (median [interquartile range 25/75]; age: 20.0 [19.3/21.0] y) were randomly allocated to percussive massage group (n = 12), foam roller group (n = 12), and control group (n = 12). First, a fatigue protocol targeting quadriceps femoris was performed. Then, participants received soft tissue mobilization with foam roller/percussive massage or rested for 10 minutes according to their groups. Pain and fatigue were evaluated by a visual analog scale, and the skin surface temperature of over the quadriceps femoris was measured with thermal camera imaging. Evaluations were performed at baseline, following fatigue protocol, at 24th hour, and at 48th hour. Changes from the baseline at 24th and 48th hours were compared between groups. Results: No significant between-group differences were observed at the assessments performed at 24th or 48th hour regarding the changes from baseline in pain (P value for 24th hour = .905, P value for 48th hour = .733), fatigue (P value for 24th hour = .895, P value for 48th hour = .606), or skin surface temperature measurements (P values for 24th hour = between .300 and .925, P values for 48th hour = between .311 and .750). Conclusions: Soft tissue mobilizations applied with foam roller or percussive massage device do not seem to be superior to passive resting in alleviating DOMS symptoms in recreational athletes.

INTRODUCTION: The evidence for spinal cord stimulation (SCS) has been criticized for the absence of blinded, parallel randomized controlled trials (RCTs) and limited evaluations of the long-term effects of SCS in RCTs. The aim of this study was to determine whether evoked compound action potential (ECAP)-controlled, closed-loop SCS (CL-SCS) is associated with better outcomes when compared with fixed-output, open-loop SCS (OL-SCS) 36 months following implant. METHODS: The EVOKE study was a multicenter, participant-blinded, investigator-blinded, and outcome assessor-blinded, randomized, controlled, parallel-arm clinical trial that compared ECAP-controlled CL-SCS with fixed-output OL-SCS. Participants with chronic, intractable back and leg pain refractory to conservative therapy were enrolled between January 2017 and February 2018, with follow-up through 36 months. The primary outcome was a reduction of at least 50% in overall back and leg pain. Holistic treatment response, a composite outcome including pain intensity, physical and emotional functioning, sleep, and health-related quality of life, and objective neural activation was also assessed. RESULTS: At 36 months, more CL-SCS than OL-SCS participants reported ≥50% reduction (CL-SCS=77.6%, OL-SCS=49.3%; difference: 28.4%, 95% CI 12.8% to 43.9%, p

PURPOSE: The pupil displays chaotic oscillations, also referred to as pupillary unrest in ambient light (PUAL). As pain has previously been shown to increase pupillary unrest, the quantitative assessment of PUAL has been considered a possible tool to identify and quantify pain. Nevertheless, PUAL is affected by various states, such as vigilance, cognitive load, or emotional arousal, independent of pain. Furthermore, systematically applied opioids are known to reduce PUAL, thus potentially limiting its usefulness to detect pain or changes in pain intensity. To test the hypothesis that PUAL can reliably identify changes in pain intensity in a clinical setting, we measured PUAL in patients experiencing substantial pain relief when regional anesthesia interventions were applied after surgery. METHODS: We conducted an observational study at an academic surgery centre following institutional review board approval. Eighteen patients with unsatisfactory pain control following surgery underwent regional anesthesia procedures to improve pain control. We used infrared pupillometry to assess pupillary unrest before and after the regional block. We then compared the changes in pupillary unrest with the changes in pain scores (numeric rating scale [NRS], range 0-10). RESULTS: Eighteen patients received epidural anesthesia (n = 14) or peripheral nerve blocks (n = 4), resulting in improvement of mean (standard deviation [SD]) NRS pain scores from 7.2 (1.7) to 1.9 (1.8) (difference in means, -2.2; 95% confidence interval [CI], -6.3 to -4.1; P

INTRODUCTION: Chronic pain patients may experience impairments in multiple health-related domains. The design and interpretation of clinical trials of chronic pain interventions, however, remains primarily focused on treatment effects on pain intensity. This study investigates a novel, multidimensional holistic treatment response to evoked compound action potential-controlled closed-loop versus open-loop spinal cord stimulation as well as the degree of neural activation that produced that treatment response. METHODS: Outcome data for pain intensity, physical function, health-related quality of life, sleep quality and emotional function were derived from individual patient level data from the EVOKE multicenter, participant, investigator, and outcome assessor-blinded, parallel-arm randomized controlled trial with 24 month follow-up. Evaluation of holistic treatment response considered whether the baseline score was worse than normative values and whether minimal clinical important differences were reached in each of the domains that were impaired at baseline. A cumulative responder score was calculated to reflect the total minimal clinical important differences accumulated across all domains. Objective neurophysiological data, including spinal cord activation were measured. RESULTS: Patients were randomized to closed-loop (n=67) or open-loop (n=67). A greater proportion of patients with closed-loop spinal cord stimulation (49.3% vs 26.9%) were holistic responders at 24-month follow-up, with at least one minimal clinical important difference in all impaired domains (absolute risk difference: 22.4%, 95% CI 6.4% to 38.4%, p=0.012). The cumulative responder score was significantly greater for closed-loop patients at all time points and resulted in the achievement of more than three additional minimal clinical important differences at 24-month follow-up (mean difference 3.4, 95% CI 1.3 to 5.5, p=0.002).

ObjectivePeople commonly cope with chronic low back pain (cLBP) by ignoring and distraction. Can mindful interoceptive exposure to the pain sensation itself and its phenomenological components be an alternative approach?MethodsSingle-arm feasibility study in patients with cLBP using a 2-minute attention exercise guided by a smartphone app several times per day over 8 weeks. We assessed feasibility, pre/post pain, function, and psychological parameters using mixed methods: standard questionnaires, ecological momentary assessment, and exit interviews that included micro-phenomenology technique and subsequent reflexive thematic qualitative analysis.ResultsWe enrolled 31 participants, mostly female, mean age 48, the majority had pain for >5 years; 29 completed. Mean pain intensity [0-10] improved from 4.8 ±1.7 to 3.1 ±1.9 (p < .0001); mean PEG scores (intensity and interference with daily life; range 0-30) improved from 13.7 ±6.2 to 8.4 ±6.6 (p < .0001); pain impact (9 items incl physical function) 22.3 ±8.7 to 19.7 ±8.1 (p = .0010). Twenty-one of 29 improved PEG score ≥30%. There were significant improvements in PCS Rumination and MAIA Not-Worrying. Participants became aware of their usual habit of avoidance and the challenge of and resistance to focusing on pain. They were surprised how pain sensations varied over time, and that pain intensity and the threat value of pain could diminish by focusing on it. They described a variety of 3D pain shapes (e.g., football, pool ball, rod, nail, brick, stars) with a range of colors, transparency, temperature, and density that for some changed with mindful attention. Most struggled to find appropriate words for sensory awareness and attention regulation and found that the threat value of their pain diminished.ConclusionsMindful interoceptive exposure to the sensations of their cLBP using a 2-minute attention exercise with a phone app-rather than ignoring and distracting from it-may be a beneficial intervention for cLBP.Trial registrationClinicalTrials.gov #NCT06186193.

BACKGROUND: Parasympathetic tone activity (PTA) in response to nociceptive stimulus in conscious non-sedated horses is unknown. OBJECTIVES: Study PTA, heart rate (HR), and horse grimace scale (HGS) at rest and during mechanical nociceptive stimulation. ANIMALS: Ninety healthy young adult horses (females, males): 30 each of Friesians, Quarter Horses, and Warmbloods. METHODS: Prospective control study. The study consisted of habituation to equipment (Day 1), baseline recordings (Days 2 and 3), and nociceptive testing applying mild pressure to the metacarpus (Day 4). Parasympathetic tone, HR, and HGS were recorded simultaneously on Days 2 to 4. Each study lasted 30 minutes and was done in triplicate at 3 different time points per day. RESULTS: Baseline PTA was not different among breeds. It decreased in Warmbloods and Quarter Horses during placement of the stimulus device without stimulation (P

BackgroundTools, such as the STarTBack Screening Tool (SBT), have been developed to identify risks of progressing to chronic disability in low back pain (LBP) patients in the primary care population. However, less is known about predictors of change in function after treatment in the specialty care population.ObjectiveWe pursued a retrospective observational cohort study involving LBP patients seen in a multidisciplinary specialty clinic to assess which features can predict change in function at follow-up.MethodsThe SBT was administered at initial visit, and a variety of patient characteristics were available in the chart including the presence of chronic overlapping pain conditions (COPCs). Patient Reported Outcomes Measurement Information System-10 (PROMIS-10) global physical health (PH) and global mental health (MH) were measured at baseline and at pragmatic time points during follow-up. Linear regression was used to estimate adjusted associations between available features and changes in PROMIS scores.Results241 patients were followed for a mean of 17.0 ± 7.5 months. Mean baseline pain was 6.7 (SD 2.1), PROMIS-10 global MH score was 44.8 (SD 9.3), and PH score was 39.4 (SD 8.6). 29.7% were low-risk on the SBT, 41.8% were medium-risk, and 28.5% were high-risk. Mean change in MH and PH scores from baseline to the follow-up questionnaire were 0.86 (SD 8.11) and 2.39 (SD 7.52), respectively. Compared to low-risk patients, high-risk patients had a mean 4.35 points greater improvement in their MH score (p= 0.004) and a mean 3.54 points greater improvement in PH score (p= 0.006). Fewer COPCs also predicted greater improvement in MH and PH.ConclusionsSBT and the presence of COPC, which can be assessed at initial presentation to a specialty clinic, can predict change in PROMIS following treatment. Effort is needed to identify other factors that can help predict change in function after treatment in the specialty care setting.

BackgroundWe aimed to characterize pain and analgesic use in a large contemporary cohort of patients with cirrhosis and to associate pain with unplanned health care utilization and clinical outcomes in this population.MethodsWe included all patients with cirrhosis seen in UCSF hepatology clinics from 2013 to 2020. Pain severity and location were determined using documented pain scores at the initial visit; "significant pain" was defined as moderate or severe using established cutoffs. Demographic, clinical, and medication data were abstracted from electronic medical records. Associations between significant pain and our primary outcome of 1-year unplanned health care utilization (ie, emergency department visit or hospitalization) and our secondary outcomes of mortality and liver transplantation were explored in multivariable models.ResultsAmong 5333 patients with cirrhosis, 32% had a nonzero pain score at their initial visit and 25% had significant (ie moderate/severe) pain. Sixty percent of patients with significant pain used ≥1 analgesic; 34% used opioids. Patients with cirrhosis with significant pain had similar Model for End-Stage Liver Disease-Sodium scores (14 vs. 13), but higher rates of decompensation (65% vs. 55%). The most common pain location was the abdomen (44%). Patients with abdominal pain, compared to pain in other locations, were more likely to have decompensation (72% vs. 56%). Significant pain was independently associated with unplanned health care utilization (adjusted odds ratio: 1.3, 95% CI: 1.1-1.5) and mortality (adjusted hazard ratio: 1.4, 95% CI: 1.2-1.6).ConclusionsPain among patients with cirrhosis is often not well-controlled despite analgesic use, and significant pain is associated with unplanned health care utilization and mortality in this population. Effectively identifying and treating pain are essential in reducing costs and improving quality of life and outcomes among patients with cirrhosis.

Background: Hip and groin problems are common among team-sport athletes. However, few studies have been conducted in female athletes that have used the Doha Agreement classification system to categorize these problems. Purpose: The purpose of this study was to examine the preseason point prevalence of hip and groin problems in elite female team-sport athletes. Secondary aims were to categorize the groin problems according to the Doha Agreement classification system and to explore the association between hip muscle strength and self-reported hip and groin function. Study Design: Cross-sectional study. Methods: Female athletes who participated in various sports underwent preseason assessment of isometric hip adduction and abduction strength, with pain levels recorded during respective contractions, and self-reported function on the Copenhagen Hip and groin Outcome Score (HAGOS). If any athlete reported current hip and groin problems during this screening assessment, a full, standardized clinical hip and groin examination was undertaken. These hip and groin problems were then categorized according to the Doha Agreement classification system. Comparisons between the participants with vs without hip and groin problems were made, and correlational statistics were used to examine relationships between strength and HAGOS scores. Results: Ninety-one elite female athletes from six different sports were included in the study. Thirteen athletes reported current hip and groin problems, with an overall prevalence rate of 14.3%. Iliopsoas-related groin pain was the most common category diagnosed, accounting for 58.8% of cases, followed by hip-related groin pain (17.6%), adductor-related (11.8%), and inguinal- and pubic-related pain (both 5.9%). No association was found between strength and function. Conclusion: The hip and groin point prevalence in female athletes documented during preseason appears to be similar to those reported in male athletes. Iliopsoas-related groin pain was the most common clinical entity reported in female athletes in this study. There was no association between hip muscle strength and self-reported hip and groin function. Level of Evidence: 3b [ABSTRACT FROM AUTHOR]

Background: After anterior cruciate ligament reconstruction (ACLR), asymmetry is likely to persist in single-leg (SL) vertical jump and drop jump performance than in SL hop distance. However, its relationship with the return to sport (RTS) remains unclear. Hypothesis/Purpose: This study aimed to determine the association between vertical jump performance after primary ACLR using hamstring tendon autograft and RTS at a pre-injury competitive level. Study design: Cross-sectional study Methods: Patients who underwent primary ACLR using hamstring tendon autograft were recruited for this study. Participants who returned to pre-injury competition after ACLR were recruited at least eight months postoperatively. Knee condition was assessed, including joint laxity, range of motion, muscle strength, and knee pain intensity during sports activities. Performance variables were also assessed, including SL hop distance, jump height in SL vertical jump, and reactive strength index (RSI; jump height/contact time) in SL drop jump. Participants were asked to subjectively report whether they had returned to the same level of competition as pre-injury and their perceived sport performance intensity. Those who answered "Yes" to the dichotomous question and had a postoperative subjective athletic performance of > 80% were categorized into the Yes-RTS group. The primary outcome was the ability to achieve RTS at the preinjury level. Results: Sixty-five patients (female, 35; male, 30) at 13.0 (13.0) [median (interquartile)] months after ACLR participated in this study. Thirty-nine (60%) were assigned to the Yes-RTS group. Regarding knee conditions, the No-RTS group had a significantly higher knee pain intensity, as assessed using a numerical rating scale (p<0.001, effect size -0.45). In the performance tests, the No-RTS group exhibited a significantly lower limb symmetry index of RSI during the SL drop jump compared to the Yes-RTS group (p=0.002, effect size 0.81). Conclusion: Patients unable to achieve RTS after primary ACLR using hamstring grafts are more likely to exhibit asymmetric performance during the SL drop jump test, suggesting the significance of assessing jump symmetry when evaluating post-ACLR rehabilitation success.

ABSTRACT Background Aim Methods Results Conclusions The heart rate variability–based Newborn Infant Parasympathetic Evaluation (NIPE) Index is a continuous noninvasive tool for the assessment of pain and discomfort in infants. Little is known about its performance in the pediatric intensive care unit (PICU) setting, where assessment of pain/discomfort is usually based on discontinuous observational scoring systems or personal experience of medical staff.Evaluation of the performance of NIPE as an indicator of procedural pain and/or discomfort in conscious mechanically ventilated PICU patients.Procedural pain/discomfort was simultaneously assessed during pain‐ or stressful procedures by two validated discontinuous clinical scoring systems (FLACC and COMFORT‐B scale) and the NIPE.NIPE values, FLACC‐ and COMFORT‐B scores were recorded in 17 infants with a mean age of 1.2 (range 0.8–5.9) months. NIPE values associated with positive FLACC‐ (≥ 4; indicative of pain) and/or COMFORT‐B (≥ 17, indicative of discomfort) scores were lower (p < 0.001) than when associated with negative FLACC (< 4) and/or COMFORT‐B (< 17) scores with 95% CI's of a difference of −14 to −11 (FLACC), −13 to −11 (COMFORT‐B) and −14 to −11 (FLACC and COMFORT‐B), with significant interindividual variability in NIPE values. Logistic regression analyses revealed odds ratios between 0.84 and 0.85; the adjacent receiver operating curve analyses showed areas under the curve between 0.83 and 0.88. NIPE data recording failure occurred during 49.3% of the periods with a FLACC ≥ 4% and 40.7% with a COMFORT‐B ≥ 17.The NIPE detects procedural pain and discomfort in conscious mechanically ventilated infants with an accuracy comparable to established clinical scoring systems. However, because of significant interindividual variability of NIPE values and frequent data recording failure associated with patient movement, we believe it is premature to recommend its use in conscious infants.

Background: Chronic pain poses a clinical challenge due to its associated costly disability and treatment needs. Determining how pain transitions from acute to chronic is crucial for effective management. Upregulation of the chemokine C-X-C motif ligand 12 (CXCL12) in nociceptive pathway is associated with chronic pain. Our previous study has reported that elevated plasma CXCL12 mediates intracerebral neuroinflammation and the comorbidity of cognitive impairment in neuropathic pain, but whether it is also involved in the pathogenesis of pathologic pain has not been investigated. Methods: Intravenous or intrathecal injection (i.v. or i.t.) of recombinant mouse CXCL12, neutralizing antibody (anti-CXCL12) or AMD3100 [an antagonist of its receptor C-X-C chemokine receptor type 4 (CXCR4)] was used to investigate the role of CXCL12 signaling pathway in pain chronicity. Two behavioral tests were used to examine pain changes. ELISA, immunofluorescence staining, Western blot, quantitative Real Time-PCR and Cytokine array were applied to detect the expressions of different molecules. Results: We found that increased plasma CXCL12 was positively correlated with pain severity in both chronic pain patients and neuropathic pain model in mice with spared nerve injury (SNI). Neutralizing plasma CXCL12 mitigated SNI-induced hyperalgesia. A single i.v. injection of CXCL12 induced prolonged mechanical hyperalgesia and activation of the nociceptive pathway. Multiple intravenous CXCL12 caused persistent hypersensitivity, enhanced structural plasticity of nociceptors and up-regulation of the CXCL12/CXCR4 axis in the dorsal root ganglion (DRG) and spinal dorsal horn (SDH). However, intrathecal blocking of CXCL12/CXCR4 pathway by CXCL12 antibody or CXCR4 antagonist AMD3100 significantly alleviated CXCL12-induced pain hypersensitivity and pathological changes. Conclusions: Our study provides strong evidence that a sustained increase in plasma CXCL12 contributes to neuropathic pain through a positive feedback loop that enhances nociceptor plasticity, and suggests that targeting CXCL12/CXCR4 axis in plasma or nociceptive pathways has potential value in regulating pain chronicity. Highlights: 1) Plasma CXCL12 in neuropathic pain states were positively correlated with pain severity. 2) A sustained increase in plasma CXCL12 contributes to pain chronicity. 3) Elevated plasma CXCL12 enhances spinal synaptic structural plasticity of pain through positive feedback.

Background: The opioid epidemic is a public health crisis. However, opioid prescription recommendations have not been established in gynecological oncology, and guidelines that incorporate patient-reported pain are lacking. Objectives: The article aims to evaluate prescribing patterns, utilization, and patient-reported pain control in gynecological oncology patients at a large tertiary academic center. Methods: This was a two-phase, prospective cohort study. For Phase 1, patients undergoing hysterectomy through the gynecological oncology division at the University of New Mexico were enrolled. Postoperative opioid use was collected and standardized to oral morphine milligram equivalents (MMEs). The factors associated with outpatient opioid use were used to develop an opioid prescription algorithm. In Phase 2, we evaluated the implementation of the prescription algorithm. For both phases, patients completed a demographic survey, satisfaction survey, and validated pain questionnaires. Results: In Phase 1, the amount of opioids used was significantly lower than the amount of opioids prescribed. Factors that correlated with postoperative opioid use included surgical procedures and last 24-hour inpatient MME use. A standardized opioid prescription algorithm was developed by incorporating these factors. In Phase 2, the opioid prescribing algorithm there was no significant difference in pain scores between the two phases. Conclusions: Opioids were substantially overprescribed in gynecological oncology patients undergoing hysterectomy. Our study found that the surgical route and last 24-hour MME inpatient usage were reliable predictors of outpatient opioid use. We developed and implemented a standardized opioid prescription algorithm that was validated by comparing the pain control measures in the two phases. [ABSTRACT FROM AUTHOR]

Objective: The goal was to develop and validate classification criteria for axial juvenile spondyloarthritis (SpA; AxJSpA). Methods: This international initiative consisted of four phases: (1) item generation, (2) item reduction, (3) criteria development, and (4) validation of the AxJSpA criteria by an independent team of experts in an internationally representative validation cohort. Results: These criteria are intended to be used on youth with a physician diagnosis of juvenile SpA and for whom axial disease is suspected. Item generation consisted of a systematic literature review and a free‐listing exercise using input from international physicians, which collectively resulted in 108 items. After the item reduction exercise and expert panel input, 37 items remained for further consideration. The final AxJSpA criteria domains included the following: imaging of active inflammation, imaging of structural lesions, pain chronicity, pain pattern, pain location, stiffness, and genetics. The most heavily weighted domains were active inflammation and structural lesions on imaging. Imaging typical of sacroiliitis was deemed necessary, but not sufficient, to classify a youth with AxJSpA. The threshold for classification of AxJSpA was a score of ≥55 (out of 100). When tested in the validation data set, the final criteria had a specificity of 97.5% (95% confidence interval [CI] 91.4%–99.7%), sensitivity of 64.3% (95% CI 54.9%–73.1%), and area under the receiver operating characteristic curve of 0.81 (95% CI 0.76%–0.86%). Conclusion: The new AxJSpA classification criteria require an entry criterion and a physician diagnosis of juvenile SpA and include seven weighted domains. The AxJSpA classification criteria are validated and designed to identify participants for research studies. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to enhance the current knowledge of the relationship between the gut microbiome and osteoarthritis (OA) and associated pain using pet dogs as a clinically relevant translational model. Methods: Fecal samples were collected from 93 owned pet dogs. Dogs were designated as either clinically healthy or OA pain using validated methods. Metagenomic profiling was performed through shotgun sequencing using the Illumina NovaSeq platform. MetaPhlAn2 and HUMAnN2 were used to evaluate bacterial taxonomic and pathway relative abundance. Comparisons between healthy and OA‐pain groups were performed individually for each taxa using nonparametric tests following Benjamini and Hochberg adjustment for multiple comparisons. Permutation analysis of variance was performed using Bray‐Curtis distance matrices. All downstream analyses were completed in R. Results: No significant differences between healthy and OA‐pain dogs were observed for alpha and beta diversity. We found 13 taxa with nominally significant (P < 0.05) associations with OA case status, but none of the associations remained significant after adjustment for multiple comparisons. No differences in alpha or beta diversities or the Firmicutes to Bacteroidetes ratio were found regarding pain severity, mobility or activity level, age, or body composition score. Conclusion: Similar to recent studies in humans, the present study did not demonstrate a significant difference in the fecal microbial communities between dogs with OA pain and healthy control dogs. Future research in this naturally occurring model should expand on these data and relate the gut microbiome to gut permeability and circulating proinflammatory and anti‐inflammatory molecules to better understand the influence of the gut microbiome on OA and OA pain.

Objectives To test the hypothesis that photographs (in addition to self-reported data) can be collected daily by patients with SSc using a smartphone app designed specifically for digital lesions, and could provide an objective outcome measure for use in clinical trials. Methods An app was developed to collect images and patient-reported outcome measures including Pain score and the Hand Disability in Systemic Sclerosis-Digital Ulcers (HDISS-DU) questionnaire. Participants photographed their lesion(s) each day for 30 days and uploaded images to a secure repository. Lesions were analysed both manually and automatically, using a machine learning approach. Results Twenty-five patients with SSc-related digital lesions consented, of whom 19 completed the 30-day study, with evaluable data from 27 lesions. Mean (s. d.) baseline Pain score was 5.7 (2.4) and HDISS-DU 2.2 (0.9), indicating high lesion- and disease-related morbidity. A total of 506 images were used in the analysis [mean number of used images per lesion 18.7 (s. d. 8.3)]. Mean (s. d.) manual and automated lesion areas at day 1 were 11.6 (16.0) and 13.9 (16.7) mm2, respectively. Manual area decreased by 0.08 mm2 per day (2.4 mm2 over 30 days) and automated area by 0.1 mm2 (3.0 mm2 over 30 days). Average gradients of manual and automated measurements over 30 days correlated strongly (r = 0.81). Manual measurements were on average 40% lower than automated ones, with wide limits of agreement. Conclusion Even patients with significant hand disability were able to use the app. Automated measurement of finger lesions could be valuable as an outcome measure in clinical trials.

Purpose: Hypermobility spectrum disorders (HSD) and Ehlers-Danlos syndromes (EDS) are multisystem conditions marked by dysfunctional connective tissue. This feasibility study evaluated a 9-week integrative medicine program in this population. Methods: Using a single-arm study design, adults with HSD or EDS were given recommendations for an anti-inflammatory Mediterranean diet and self-management with additional behavioral and psychosocial support. Preliminary data on feasibility based on recruitment and retention, adherence to the diet, mobile app tracking, changes to perceived well-being via health outcomes, and satisfaction with care were obtained. Results: Thirteen participants were enrolled within a 4-month timeframe. Eight participants completed the study. Three participants met dietary tracking requirement in at least 4 of 8 intervention weeks and met the macronutrient requirements in at least half of the weeks tracked. No decreases in VAS pain scores after 5 and 9 weeks were noted; however, 62.5% (n = 5) of participants had decreased pain at 9 weeks, compared to baseline. There were significant improvements (p<.05) in six of twelve measurements of satisfaction with care at the end of the intervention. Conclusion: This study provides a foundation for future research on patient experience and introduces a novel treatment paradigm focused on nutrition and self-management. Trial Registration: National Institutes of Health clinicaltrials.gov; identifier: NCT04734041. IMPLICATIONS FOR REHABILITATION: Lifestyle and dietary interventions are relatively safe and well tolerated in the hypermobility spectrum disorder (HSD) and Ehlers-Danlos disorder (EDS) population. Participants in our 9-week integrative medicine program actively engaged in self-management of their condition and showed promising adherence to dietary and tracking requirements. Effective treatment of the intricacies and dynamics of these highly variable and clinically heterogeneous disorders may require a network of healthcare providers, integrative healthcare, as well as behavioral and psychosocial support. Dietary tracking through mobile apps might help promote self-efficacy and adherence to dietary changes. Symptom tracking might be an effective way for patients to track changes to their health and could provide valuable information for health professionals engaged in managing the disorders.

Purpose: To translate and cross-culturally adapt the King's Parkinson's Disease Pain Scale (KPPS) into Spanish. Methods: The English KPPS was forward translated into Spanish, back translated, and revised by the original developers. Cross-cultural adaptation of relevant target groups was conducted following COSMIN standards. Cognitive pretesting in Spanish people with Parkinson's Disease (PD) and pain was performed via three semi-structured focus group meetings. Changes were implemented based on qualitative and quantitative analyses. A Delphi study (two rounds) of individual assessments by Spanish experts was conducted. Changes were implemented based on the Content Validity Index (CVI) at item and scale levels (I-CVI/S-CVI). Results: Five Spanish professionals performed the initial translation. Thirty-eight inter-translation inconsistencies were identified, and consensus was reached for a unified version. After back translation and confirmation with scale developers, the pre-final Spanish KPPS was obtained. Cognitive pretesting in 30 people with PD-related pain identified 5 items where terminology changes were made to assure comprehensibility. The Delphi study in 14 Spanish experts underlined the necessity to further modify two items. After the second round, all experts agreed on the modifications and I-CVI and S-CVI were satisfactory. Conclusions: The KPPS was successfully translated and cross-culturally adapted into Spanish. IMPLICATIONS FOR REHABILITATION: The King's Parkinson's Disease Pain Scale (KPPS) was translated into Spanish by 5 independent experts. Cross-cultural validity was assessed by Spanish Parkinson's Disease (PD) patients and neurology experts. The Spanish KPPS adaptation was relevant, understandable, and comprehensive. Rehabilitation professionals will have access to the Spanish KPPS version for assessing PD-related pain in Spanish speaking patients. [ABSTRACT FROM AUTHOR]

Gender differences in pain reporting and prevalence have been demonstrated. As gender of examiner also affects reporting of pain on palpation, the aim of this study was to evaluate the effects of examiner gender on palpation performance using three different palpation methods. Examiners of both genders were instructed on the correct technique for each palpation method by either a female or male instructor. The target was to achieve a pressure of 100 kPa, corresponding to the 1 kg of force for muscle palpation described in the diagnostic criteria for temporomandibular disorders (DC/TMD). All examiners performed traditional palpation with the index finger, palpation with a palpometer, and a novel bimanual palpation with visual feedback, in a randomized order. The examiner's gender, and its interaction with the gender of the instructor did not significantly affect magnitude, accuracy, or precision of the pressure applied. The method of palpation was the only factor that significantly impacted all metrics. The palpometer achieved the lowest palpation magnitude (mean pressure applied = 113.7 kPa, 95% CI: 109.8–117.6), the highest accuracy (absolute difference = 15.7 kPa, 95% CI: 12.3–19.1), and the highest precision (mean coefficient of variation = 6.8, 95% CI: 6.0–7.6), followed by bimanual palpation and traditional palpation. The results suggest that gender differences in pain reporting in patients are not likely to be a result of the technical aspects associated with the gender of the examiner. Instead, these differences may be attributed to other factors, such as sociocultural influences. [ABSTRACT FROM AUTHOR]

Background: Chronic pelvic pain (CPP) in women is a debilitating condition with symptoms that affect both medical and psychological systems, yet for those with idiopathic CPP (i.e., those without a known physiologic cause), no consensus for intervention exists. Aim: A systematic review was conducted to identify the effectiveness of current biomedical, psychosocial, and integrative interventions for idiopathic CPP (ICPP). Method: Five databases (PubMed, CINAHL, Cochrane, PsycInfo, Web of Science) were systematically searched with multiple keywords for publications from 2008–2022. Articles were coded for sample characteristics, research design, type of intervention, and intervention outcomes. Results: Nineteen studies met criteria. The majority of the interventions (14 studies) were biomedical, either invasive (e.g., injections), or non-invasive (e.g., medications). Five studies evaluated integrative interventions that combined biomedical and psychosocial components (e.g., a multimodal pain treatment center). Invasive biomedical interventions were better at relieving short-term pain and non-invasive biomedical interventions were superior for long-term pain; integrated interventions reduced both short-term and long-term pain. Integrative interventions also improved mental health, sexual health, and QOL. Conclusion: Although most interventions for ICPP have been biomedical, integrative interventions showed greater outcome effectiveness, suggesting a focus on integrative interventions in the future.

Background: Emerging literature has demonstrated deficits in interoception (i.e., the perception of physical sensations from inside the body) in individuals with chronic pain conditions. Mind-body therapies (MBTs) are purported to improve chronic pain in part through improving or restoring interoceptive abilities. The present systematic review and meta-analysis aimed to examine changes in interoception in MBTs for chronic pain conditions. Methods: A systematic search of PubMed, PsycINFO, Scopus, CINAHL, and ProQuest Dissertation and Theses was conducted from database inception to February 2023. English language intervention studies evaluating the effect of MBTs on interoception in adults with chronic pain conditions were examined. Changes in pain (severity and interference) following treatment were examined as secondary outcomes. Results: A total of 11 studies (10 unique samples) were identified. Meta-analytic results reveal significant improvements in total interoceptive awareness (Becker's d = 1.168, p <.01) as well as improvements in seven of eight subdomains of interoceptive awareness (ds = 0.28 to 0.81). MBTs were also associated with reductions in both pain intensity (d = -1.46, p =.01) and pain interference (d = -1.07, p <.001). Conclusions: Preliminary research suggests that MBTs demonstrate improvements in interoceptive awareness and reduce pain in adults with chronic pain. Literature on changes in other domains of interoception, such as interoceptive accuracy, following MBTs is severely lacking. Although more rigorous studies are needed to corroborate results, the present findings lay an important foundation for future research to examine interoception as a possible underlying mechanism of MBTs to improve pain outcomes.

Background: Over the past two decades, biopsychosocial models of education have emerged for the treatment of various conditions, including neck pain (NP). One increasingly popular biopsychosocial education method is Pain Neuroscience Education (PNE), which educates patients about the neurobiological and neurophysiological basis of their conditions. Objectives: To review the evidence for the effectiveness of PNE as a treatment approach for patients with NP. Design: A scoping literature review. Methods: We searched the PubMed, PEDro and Scopus databases, conducted an additional non-systematic search in the GoogleScholar database and reviewed the reference lists of identified systematic reviews on this topic. We included articles with any experimental research design that: examined patients with non-traumatic NP; examined the effects of the PNE method alone or in combination with other therapeutic interventions; compared the effects of the PNE intervention with any type of therapeutic intervention or with no intervention. Results and conclusions: The searches identified 216 potentially relevant studies, 9 of which met our inclusion criteria. The included studies examined the effects of the PNE method on pain intensity (7/9 studies), catastrophizing (6/9 studies), kinesiophobia (5/9 studies), and disability (6/9 studies). The results of this review suggest that PNE, when integrated into multimodal treatment plans, can help improve pain-related outcomes and overall quality of life in CNP patients. Further research is needed to investigate the specific benefits of combining PNE with different therapeutic modalities in different patient subgroups. [ABSTRACT FROM AUTHOR]

Background: In spite of known detrimental effects of physical inactivity and sitting, little is known about levels of physical activity (PA) and sitting in adults with chronic whiplash associated disorders (WAD) and their effects on health outcomes. Methods: This cross-sectional study compared PA and sitting levels between 258 adults with WAD and 30 healthy controls. Adults with WAD were divided into four categories based on achieving 'low' or moderate-to-vigorous PA ('MVPA') levels and sitting greater ('high sit')/less ('low sit') than 8 hours daily on the International Physical Activity Questionnaire. Kruskal-Wallis tests compared health outcomes across these categories, followed by Mann–Whitney tests for pairwise comparisons. Results: Adults with WAD demonstrated lower levels of PA (2151 vs. 4097 MET minutes/week, p<.001), and higher levels of sitting (343 vs. 232 min per day, p<.001) than healthy controls. Significant differences were found between all four categories on all five health outcomes (pain intensity, pain interference, disability, physical health, mental health). Low PA/High Sit had higher disability and lower physical and mental health when compared to MVPA/High Sit and MVPA/Low Sit. Low PA/Low Sit demonstrated higher pain intensity than other groups; higher pain interference and disability and lower physical and mental health when compared to MVPA/High Sit or MVPA/Low Sit. Conclusions: Adults with WAD demonstrated lower levels of PA and higher levels of sitting. Achieving recommended levels of MVPA appeared to be associated with better health outcomes, regardless of sitting times. Both levels of PA and sitting need to be considered in management of WAD.

Purpose: To investigate the association between acute pain trajectory over one week and patient-reported outcomes (PRO) at 6-months following lumbar surgery in patients with lumbar degenerative disease (LDD). Methods: Two hundred and fifty-five subjects with LDD who received surgical treatment at our hospital between April 2019 and March 2022. Acute pain trajectory was measured using a pain trajectory calculator to determine an approximate line using the linear least squares method based on pain intensity on postoperative days 1, 3, 5, and 7. The pain trajectory-slope, which represents the change in postoperative pain intensity of the calculated approximation line, was evaluated as the main exposure for the present study. The PRO was assessed using the Oswestry Disability Index (ODI) measured at 6 ± 1 months postoperatively. Poor PRO scores in this study were defined using a threshold of an ODI of 22% or greater, which represents the patient acceptable symptomatic state after lumbar spine surgery. Multivariable logistic regression analysis including covariates was performed to investigate the association between pain trajectory-slope and PRO at 6-months following lumbar surgery. Results: In this study, 101 (39.6%) had poor PRO scores. Multivariable logistic regression analysis adjusted for covariates showed that pain trajectory-slope was associated with the poor PRO scores (odd ratios; 1.203, 95% confidence intervals; 1.130–1.288). Conclusions: The results of this study show that acute pain trajectory is significantly associated with poor PRO scores 6-months after lumbar surgery. Patients with slower pain relief or worsening pain were associated with poor PRO scores. [ABSTRACT FROM AUTHOR]

Objective: We aimed to prospectively evaluate the association between leisure-time physical activity and outcomes related to low back pain (LBP), such as pain intensity and daily activity limitation. Methods: We analyzed data from the PAMPA (Prospective Study about Mental and Physical Health) cohort, a longitudinal study with adults residing in Southern Brazil. Participants answered an online-based, self-administered questionnaire. Physical activity was assessed as minutes per week, and those who reported engaging in 150 min/week or more were considered active. We also assessed the types of activities participants engaged. Pain intensity was assessed with a numeric pain rating scale (from 0 to 10), and participants reported whether their pain restricted their daily activities. Generalized linear models were used to investigate the association between physical activity and LBP outcomes. Results: Data from 991 individuals (82.7% women) aged 38.9 ± 13.9 were analyzed. Pain intensity was higher in those inactive in waves one (β: 0.54; 95 % CI 0.23, 0.86), three (β: 0.38; 95% CI 0.02, 0.75), and four (β: 0.48; 95% CI 0.06, 0.90). Also, being physically inactive at wave one was associated with a higher probability of daily activity limitation at waves two (IRR 1.77; 95% CI 1.27; 2.46), three (IRR 1.63; 95% CI 1.17, 2.29), and four (IRR 1.73; 95% CI 1.20, 2.50). Conclusion: Not practicing at least 150 min/week of physical activity resulted in higher levels of pain and an increased risk of daily activity limitation in individuals with LBP. Moreover, various forms of activities have shown to be advantageous in alleviating pain among this group. [ABSTRACT FROM AUTHOR]

Aim: To explore registered nurses' beliefs regarding pain assessment in people living with dementia. Design: A descriptive exploratory qualitative study informed by the Theory of Planned Behaviour. Methods: Online semi‐structured in‐depth interviews were conducted from January to April 2023 with a purposive sample of 15 registered nurses caring for people with dementia. Following transcription, data were analysed using direct content analysis. Findings: Registered nurses believe pain assessment improves the well‐being of people with dementia and informs and evaluates practice. However, there is a possibility of misdiagnosing pain as agitation or behavioural problems, leading to inaccurate pain management. Interpersonal factors, such as registered nurses' knowledge and experience, beliefs and motivation to improve care provision, were the primary facilitators of pain assessment. Physical and behavioural dimensions of the pain of the dementia syndrome were the most reported barriers to pain assessment. Registered nurses reported that multidisciplinary team members expect them to do pain assessments. Most did not experience disapproval when performing pain assessments. Conclusion: Registered nurses hold beliefs about pain assessment benefits, consequences, enablers, barriers, approvals and disapprovals regarding dementia. The findings could inform interventions to enhance pain assessment practices. Implications for the Profession and/or Patient Care: Policymakers should provide education opportunities for registered nurses to improve their knowledge, skills and beliefs about pain assessment in dementia. Future research should develop and implement multidisciplinary, multifaceted pain assessment protocols to enhance the accuracy of pain assessment practices. Impact: Pain is underassessed in dementia, and this could stem from registered nurses' beliefs about pain assessment in dementia. The findings could inform interventions to enhance pain assessment beliefs and practices. Reporting Method: This study adhered to the COREQ criteria. Patient or Public Contribution: Registered nurses caring for people living with dementia participated as interview respondents. [ABSTRACT FROM AUTHOR]

Acute postsurgical pain (APSP) is an important risk factor for pain chronification, with reports of being more intense after total knee arthroplasty (TKA) than after total hip arthroplasty (THA). Psychological variables have been associated with differences in postsurgical pain experience. This study aimed to analyse the longitudinal reciprocal association between pain and anxiety levels in patients undergoing TKA or THA, to investigate the moderator role of the type of surgery and to explore psychological mediators in the anxiety – pain association. Patients undergoing TKA (n = 120) or THA (n = 109) were evaluated before surgery and in the acute postsurgical period (48 h postsurgery). Presurgical assessment comprised sociodemographic, pain-related and psychological variables (anxiety, depression, pain catastrophizing, self-efficacy, optimism and satisfaction with life). Postsurgical assessment focused on pain frequency, pain intensity and anxiety. Longitudinal associations were explored using cross-lagged panel models that included the indirect effect paths through possible mediators (pain catastrophizing and depression). Multigroup analyses compared TKA and THA. In the global sample, higher APSP was predicted by higher presurgical pain and worse presurgical anxiety. Multigroup analyses revealed that worse APSP was predicted by higher presurgical anxiety in patients undergoing TKA and by higher presurgical pain in patients undergoing THA. Furthermore, there was a positive significant indirect effect of pain catastrophizing, but not depressive symptoms, in the relationship between presurgical anxiety and APSP in THA. Anxiety and APSP are differently interrelated in TKA and THA. Psychological characteristics could be managed before surgery to favour better APSP control and potentially prevent pain chronification after total joint arthroplasty. [ABSTRACT FROM AUTHOR]

Background: Total knee arthroplasty (TKA) is a surgical procedure to improve the quality of life of patients with osteoarthritis. However, postoperative recovery can be difficult due to sleep disturbance, such as poor sleep quality, and postsurgical pain. Purpose: The aim of this systematic review was to examine recent evidence regarding changes in sleep quality after TKA and to explore factors affecting the postoperative recovery process. Methods: This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We screened the PubMed, Google Scholar, ScopeMed, and Science Direct databases in December 2022 using the keywords sleep , total knee replacement surgery , knee arthroplasty , and sleep disruptions for relevant articles published between 2011 and 2022. Seven studies met all inclusion criteria and were included in the final sample for analysis. Results: Findings revealed that sleep disturbance was common during the early stages of the TKA recovery period and may be related to pain. After three months, sleep quality improved and pain intensity decreased. Three studies found a correlation between sleep and pain; however, another three studies did not. Conclusion: Health professionals, including surgical nurses, should be aware of the potential impact of TKA on sleep quality and understand, assess, and manage sleep disturbance and pain to provide comprehensive care for their patients and enhance recovery. The authors examine recent evidence regarding changes in sleep quality after total knee arthroplasty and explore factors affecting the postoperative recovery process. [ABSTRACT FROM AUTHOR]

Purpose: In pain assessment, the commonly used Numeric Rating Scale (NRS) offers an incremental 0-to-10 range of response options. But this broad range often leads to discordant evaluations between nurses and their patients. This study aimed to compare the NRS to the three-category Interventional Pain Assessment (IPA) scale, validate the IPA scale in an inpatient setting, and determine RN and patient scale preferences. Methods: This prospective study enrolled 122 postoperative orthopedic patients and their designated 104 RNs at a level 1 trauma center in the midwestern United States. Patients were asked to verbally rate their pain from 0 to 10 using the NRS and from 0 to 2 on the IPA scale. Patients were also asked which scale best conveyed their pain. The RNs were asked which scale best informed them of their patient's pain situation and which scale they preferred. To establish a correlation between the two scales, we considered NRS values of 0 to 7 (signifying no pain to moderate pain) to correspond to IPA scale values of 0 to 1 (signifying no pain to tolerable pain). NRS values of 8 to 10 (signifying severe pain) were considered to correspond to IPA scale values of 2 (signifying intolerable pain). Responses in which patients reported IPA scores indicating no pain to tolerable pain but NRS scores above 7 or IPA scale scores indicating intolerable pain but NRS scores of 7 or below were defined as discordant answers. Results: Data analysis revealed a strong significant correlation between the NRS and IPA scale (τ = 0.597), with an 82.7% concordance rate. Once an NRS score rose above 7, more discordance between the two scales became increasingly prevalent, as evidenced by the 45% of patients who also reported tolerable pain on the IPA scale. Significantly more patients (89.3%) preferred the IPA scale to communicate their pain level than the NRS (10.7%). Significantly more RNs (76%) felt the IPA scale best informed them of their patient's pain and was a better guide for treatment than felt the NRS did so (24%). Conclusions: The IPA scale asks about pain tolerability and thus has a direct role in the management of pain medications. Both patients and nurses felt they were better able to convey and understand pain when using the IPA scale than when using the NRS. There was consensus regarding pain scale preference among patients and their RNs, with both groups preferring the IPA scale due to its simplicity and, among the RNs, its usefulness in guiding treatment. The IPA scale may be a much better tool for accurately assessing a patient's pain experience and needs, with the potential to change practice and improve pain management. This study aimed to compare the Numeric Rating Scale with the Interventional Pain Assessment (IPA) scale, validate the IPA scale in an inpatient setting, and determine RN and patient scale preferences.

Purpose: To compare the effectiveness of McKenzie neck exercise and cranio-cervical flexion (CCF) exercise on strength and endurance of deep neck flexor (DNF) muscles, pain, disability, and craniovertebral angle (CVA) in individuals with chronic neck pain. Methods: Forty individuals with chronic neck pain were randomly allocated to the McKenzie neck or CCF exercise group. Each group performed exercises at home daily. The strength and endurance of DNF muscles were measured at baseline, immediately after the first exercise session, and each week follow-up for six weeks. Average pain over the past week was measured at baseline and each week follow-up for six weeks. Disability and CVA were measured at baseline and the end of six weeks. Results: At six weeks, both groups exhibited significant improvements across all outcome variables (p < 0.001) but there were no differences between groups (p > 0.05). The significant difference from baseline in the strength of DNF muscles was observed as early as the second week of each intervention (p ≤ 0.001). The significant difference from baseline in the endurance of DNF muscles was observed as early as the first week in the CCF exercise group (p < 0.05) and the second week in the McKenzie neck exercise group (p < 0.05). A significant decrease in pain intensity from baseline was observed after the first week in the McKenzie neck exercise group (p < 0.001) while it was after the second week in the CCF exercise group (p < 0.05). Conclusion: Both the McKenzie neck exercise and CCF exercise produced similar effects in enhancing the strength and endurance of the DNF muscles, decreasing pain, alleviating neck disability, and improving the CVA.

Introduction: This study examined the efficacy of manual therapy for pain and disability measures in adults with sacroiliac joint pain syndrome (SIJPS). Methods: We searched six databases, including gray literature, on 24 October 2023, for randomized controlled trials (RCTs) examining sacroiliac joint (SIJ) manual therapy outcomes via pain or disability in adults with SIJPS. We evaluated quality via the Physiotherapy Evidence Database scale and certainty via Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Standardized mean differences (SMDs) in post-treatment pain and disability scores were pooled using random-effects models in meta-regressions. Results: We included 16 RCTs (421 adults; mean age = 37.7 years), with 11 RCTs being meta-analyzed. Compared to non-manual physiotherapy (i.e. exercise ± passive modalities; 10 RCTs) or sham (1 RCT) interventions, SIJ manual therapy did not significantly reduce pain (SMD: −0.88; 95%-CI: −1.84; 0.08, p = 0.0686) yet had a statistically significant moderate effect in reducing disability (SMD: −0.67; 95% CI: −1.32; −0.03, p = 0.0418). The superiority of individual manual therapies was unclear due to low sample size, wide confidence intervals for effect estimates, and inability to meta-analyze five RCTs with a unique head-to-head design. RCTs were of 'good' (56%) or 'fair' (44%) quality, and heterogeneity was high. Certainty was very low for pain and low for disability outcomes. Conclusion: SIJ manual therapy appears efficacious for improving disability in adults with SIJPS, while its efficacy for pain is uncertain. It is unclear which specific manual therapy techniques may be more efficacious. These findings should be interpreted cautiously until further high-quality RCTs are available examining manual therapy against control groups such as exercise.

Low back pain is a common health problem. In this study, we investigated the effects of yoga, physical therapy (PT), and home exercise (HE) on pain perception, function, stress, and quality of life in chronic low back pain (cLBP). We randomly assigned 54 participants to three distinct treatment groups: (a) a physical therapy group (PT) who received spinal stabilization exercises (SSE) combined with local heat and transcutaneous electrical stimulation; (b) a home exercise group (HE) who received SSE as part of the home program; and (c) a yoga group who received yoga exercises. The primary outcome measures were a Visual Analog Scale (VAS) for measuring pain, and the Oswestry Disability Index (ODI) to measure function. Secondary outcome measures were the Tampa Kinesiophobia Scale (TKS), Central Sensitization Inventory (CSI), pain sensitivity (L3 and deltoid R/L PPTs), Spielberger State-Trait Anxiety Inventory (STAI), plasma cortisol and DHEA-S levels, Transversus Abdominis (TrA) muscle activation, and the Nottingham Health Profile (NHP). Assessments were conducted before and after a six-week intervention period. All three groups demonstrated improvements in pain on the VAS, function on the ODI, pain sensitivity on the L3 and deltoid R/L PPTs, CSI, anxiety on the STAI, TrA muscle activation, and quality of life on the NHP (p <.05). The PT group exhibited a more pronounced improvement on the ODI score (p <.05) than the other groups. Cortisol levels only decreased in the PT group (p <.05). The exercises did not impact DHEA-S and NHP-S parameters. Thus, all interventions resulted in decreased stress, pain intensity, pain sensitivity, central sensitization, and improved function and quality of life; there was no singularly superior approach between interventions. These findings will aid in tailoring treatment programs for managing cLBP according to individual needs. [ABSTRACT FROM AUTHOR]

Objectives: Although it is the most performed invasive procedure, peripheral intravenous catheter (PIVC) insertion in children can be difficult. The primary objective of the study was to identify the factors associated with difficult intravenous access (DIVA) in the paediatric ED, including patient, proceduralist and situational factors. Methods: This was a single‐centre prospective observational cohort study conducted over 28 consecutive days. Research assistants observed PIVC insertion attempts for children under 16 years of age and recorded data for variables relating to the patient, proceduralist and event. Univariate logistic regression modelling was performed to identify factors associated with DIVA, defined as unsuccessful PIVC insertion on the first attempt. Results: A total of 134 participants were recruited; 66 were male (49%) with a median age of 5.7 years. Fifty‐two (39%) were classified as having DIVA. There was a total of 207 PIVC insertion attempts with two or more attempts needed for 48 children (36%). Patient factors associated with DIVA included age of 3 years or less and limited vein options. Proceduralist factors included gestalt of 50% or less chance of success, use of a larger gauge (smaller bore) PIVC and less PIVC insertion experience. Situational factors included a combative child, higher pain score and loud ambient noise. Conclusions: The present study identified multiple patient, proceduralist and situational factors that were associated with DIVA in the paediatric ED. Future studies should explore the development and implementation of a package to address DIVA in children, with the patient‐centred goals of reducing pain and improving success. [ABSTRACT FROM AUTHOR]
