We examined the influence of negative psychological factors (catastrophizing, distress and kinesiophobia) on delayed onset muscle soreness (DOMS) intensity, cervical function (strength and range of motion) and on daily activities (ADL), and the suitability of an exercise protocol designed to induce DOMS within the cervical region. Psychological factors and cervical function were assessed in 86 healthy participants at baseline before applying a DOMS provocation protocol in the cervical flexor muscles. After 24hour, cervical function was reassessed. In addition, at 24hour and 48hour, the intensity of DOMS and its impact on ADL were assessed using the visual analog scale (VAS). The protocol was effective given that it generated low-moderate intensity DOMS (VAS≈30 -40mm) and a statistically significant reduction in cervical strength and range of motion. Psychological distress (anxiety and depression), but not kinesiophobia and catastrophism, predicted a loss of cervical strength (explained 43% of the variance) and range of motion (explained 22% of the variance) after induction of DOMS. In addition, participants' anxiety level predicted DOMS intensity at 24hour (explained 19% of the variance). PERSPECTIVE: The present findings highlight the relevance of evaluating psychological distress as a preventive/therapeutic measure, given that high levels of distress could lead to more intense and disabling pain in acute injuries, and all these aspects are considered risk factors for the chronification of symptoms.

The Trunk Control Measurement Scale (TCMS) is a valid and reliable tool to assess static and dynamic trunk control in cerebral palsy. However, there is no evidence informing about differences between novice and expert raters. A cross-sectional study was conducted with participants between the ages of 6 and 18 years with a CP diagnosis. The TCMS Spanish version (TCMS-S) was administered in-person by an expert rater, and video recordings were taken for later scoring by the expert and three other raters with varying levels of clinical experience. The intraclass correlation coefficient (ICC) was used to evaluate reliability between raters for the total and subscales of the TCMS-S scores. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) were also calculated. There was a high level of agreement between expert raters (ICC ≥ 0.93), while novice raters demonstrated good agreement (ICC > 0.72). Additionally, it was observed that novice raters had a slightly higher SEM and MDC than expert raters. The Selective Movement Control subscale exhibited slightly higher SEM and MDC values compared to the TCMS-S total and other subscales, irrespective of the rater’s level of expertise. Overall, the study showed that the TCMS-S is a reliable tool for evaluating trunk control in the Spanish pediatric population with cerebral palsy, regardless of the rater’s experience level.

Objective: To establish the minimal clinically important difference (MCID) for inspiratory muscle strength (MIP) and endurance (IME) in individuals with long-term post-COVID-19 symptoms, as well as to ascertain which of the variables has a greater discriminatory capacity and to compare changes between individuals classified by the MCID. Design: Secondary analysis of randomised controlled trial of data from 42 individuals who performed an 8-week intervention of respiratory muscle training programme. Results: A change of at least 18 cmH2O and 22.1% of that predicted for MIP and 328.5s for IME represented the MCID. All variables showed acceptable discrimination between individuals who classified as “improved” and those classified as “stable/not improved” (area under the curve ≥0.73). MIP was the variable with the best discriminative ability when expressed as a percentage of prediction (Youden index, 0.67; sensitivity, 76.9%; specificity, 89.7%). Participants classified as “improved” had significantly greater improvements in quality of life and lung function compared with the participants classified as “stable/not improved”. Conclusion: In individuals with long-term post-COVID-19 symptoms, the inspiratory muscle function variables had an acceptable discriminative ability to assess the efficacy of a respiratory muscle training programme. MIP was the variable with the best discriminative ability, showing better overall performance when expressed as a percentage of prediction.

The purpose of the study is to establish the determinants of change in 6-min walk test (6MWT) performance observed in children aged 6-12 years over a 4-month period, and to provide test-retest reliability (4 months) to establish the minimal detectable change (MDC).Healthy children aged 6-12 years performed two 6MWT trials separated by a period of 4 months. Multiple linear regression analysis was performed to estimate the percentage of variance explained by the variables potentially predictive of the change in the 6MWT. We employed the intraclass correlation coefficient to assess test-retest reliability.Fifty-nine children (28 boys and 31 girls) were assessed. The change in distance covered during the 6MWT was significantly correlated with the growth in their height (r = 0.679; p 0.05) and the change in their weight (r = 0.473; p 0.05). Multiple linear regression analysis shows that the change in distance covered in the 6MWT was only explained by its growth in height (46.0% explained variance). The test-retest reliability was fair-good. After 4 months, we established a 12% change from the initial measurement (79.69 m) as the MDC for a 90% confidence level (MDCThe distance covered in the 6MWT improved as the children's age, weight and height increased. The growth children's height was the most important predictor of change in distance covered in the 6MWT. An increase of at least 79.69 m (MDC

Since there is an increasing rate of physiotherapists using invasive procedures during the clinical practice, understanding the cross-sectional anatomy and radiological images is essential for ensuring patients' safety during these interventions. Therefore, the aim of this study was to analyze the students' opinion of including cross-sectional and radiological images to traditional methodologies, to evaluate whether these additional resources improve their ability to identify musculoskeletal structures in radiological images and their understanding of neurovascular and visceral structures related with specific muscles to be avoided during invasive procedures. First-year undergraduate physiotherapy students were enrolled in the study. A brief online survey asking about their opinion about the use of cross-sectional and radiological images as complementary resources was built. In addition, two open-answer tests (before and after the inclusion of these resources) were conducted to evaluate their ability to identify correctly musculoskeletal structures in magnetic resonance and ultrasound images and to evaluate their awareness of high-risk structures related with specific muscles. One-hundred-thirty-two students returned the online survey and one-hundred-forty-eight completed all the tests. In general, students opined cross-sectional images to be of utility for learning anatomy (81.8%) and radiological images (93.9%) and felt they benefited from cross-sectional and ultrasound images (78.0%). All tests showed significant improvements after the inclusion of these complementary resources (all, P 0.001) except for trunk structures in MRI (P = 0.777). The implementation of anatomical cross-sectional and radiological images resulted in better understanding of radiological images and better cognition of possible risk during invasive procedures.

Background: There is clinical interest in determining the effects of low-load blood flow restriction (LL-BFR) resistance training on muscle strength and hypertrophy compared with traditional high- and low-load (HL and LL) resistance training in healthy older adults and the influence of LL-BFR training cuff-pressure on these outcomes. Methods: A search was performed on the MEDLINE, PEDro, CINHAL, Web of Science, Science Direct, Scopus, and CENTRAL databases. Results: The analysis included 14 studies. HL resistance training produces a small increase in muscle strength (eight studies; SMD, −0.23 [−0.41; −0.05]) but not in muscle hypertrophy (six studies; (SMD, 0.08 [−0.22; 0.38]) when compared with LL-BFR resistance training. Compared with traditional LL resistance training, LL-BFR resistance training produces small–moderate increases in muscle strength (seven studies; SMD, 0.44 [0.28; 0.60]) and hypertrophy (two studies; SMD, 0.51 [0.06; 0.96]). There were greater improvements in muscle strength when higher cuff pressures were applied versus traditional LL resistance training but not versus HL resistance training. Conclusions: LL-BFR resistance training results in lower muscle strength gains than HL resistance training and greater than traditional LL resistance training in healthy adults older than 60 years. LL-BFR resistance training promotes a similar muscle hypertrophy to HL resistance training but is greater than that of traditional LL resistance training. Applying cuff pressures above the limb occlusion pressure could enhance the increases in muscle strength compared with traditional LL resistance training.

Although current evidence supports the use of dry needling for improving some clinical outcomes in people with neck pain, no previous research explored the effects of dry needling on the central processing of pain and autonomic nervous system in this population. Therefore, this clinical trial aimed to compare the effects of real and sham dry needling on autonomic nervous system function, pain processing as well as clinical and psychological variables in patients with chronic nonspecific neck pain. A double-blinded randomized clinical trial including 60 patients with neck pain was conducted. Patients were randomized to the real needling (n = 30) or sham needling (n = 30) group. Skin conductance (SC), pressure pain thresholds (PPTs), temporal summation (TS), conditioned pain modulation (CPM) as well as pain intensity, related-disability, catastrophism, and kinesiophobia levels were assessed by an assessor blinded to the allocation intervention. The results did not find significant group * time interactions for most outcomes, except for the global percentage of change of SC values (mean: F = 35.90, p < 0.001, ηp2 = 0.459; minimum: F = 33.99, p = 0.839, ηp2 = 0.371; maximum: F = 24.71, p < 0.001, ηp2 = 0.037) and PPTs at C5-C6 joint in the same side of needling (F = 9.982; p = 0.003; = 0.147), in favor of the dry needling group. Although the proportion of subjects experiencing moderate to large self-perceived improvement after the intervention was significantly higher (X2 = 8.297; p = 0.004) within the dry needling group (n = 18, 60%) than in the sham needling group (n = 7, 23.3%), both groups experienced similar improvements in clinical and psychological variables. Our results suggested that dry needling applied to patients with chronic nonspecific neck pain produced an immediate decrease in mechanical hyperalgesia at local sites and produced an increase in skin conductance as compared with sham needling. No changes in central pain processing were observed. A single session of sham or real dry needling was similarly effective for decreasing related disability, pain intensity, catastrophism, and kinesiophobia levels. Further studies are needed to better understand the clinical implications of autonomic nervous system activation on central sensitization and pain processing in the long-term after the application of dry needling.

To develop a Spanish version of the international Hip Outcome Tool questionnaire (iHOT-12Sv) for assessing the psychometric characteristics (internal consistency, convergent validity, test–retest reliability, and floor and ceiling effects) of this version in physically active patients with hip pain. Methods: After conducting the translation and transcultural adaptation, a consecutive sample of patients with labral tear injury and/or femoroacetabular impingement (Pincer or Cam type) were recruited in a Spanish Hospital. Patients completed the iHOT-12Sv and the Spanish version of the iHOT-33 and the Hip Outcome Score (HOS). Internal consistency was calculated using Cronbach’s alpha; convergent validity was evaluated using Spearman correlation coefficients (Rho) with iHOT-33 and HOS; test–retest reliability was examined using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable changes (MDC); and floor and ceiling effects were calculated as the percentage of patients who obtained the minimum and maximum score. Results: One hundred and fifty-three patients (64.7% males) participated in this study. Cronbach’s alpha of 0.92 revealed the excellent internal consistency. In addition, the iHOT-12Sv demonstrated strong to very strong correlations with the HOS (Rho ranged from 0.741 to 0.827; p < 0.001) and the iHOT-33 (Rho = 0.932; p < 0.001), respectively; acceptable test-retest reliability (ICC = 0.86 to 0.94); SEM = 6.21 and MDC = 17.22; and no floor or ceiling effects were found. Conclusions: The iHOT-12Sv can be used as a valid and reliable tool for clinical evaluation of physically active patients with hip pathology. However, the full version is preferable for research purposes aiming to assess changes in hip function.

Background Quadriceps muscle plays a relevant role in soccer as its function is determinant for sprinting, jumping and striking the ball. Although ultrasound demonstrated to be useful in risk of injury prevention and monitoring post-injury rehabilitation, no studies analyzed the ultrasound muscle histology with sports performance tests. We aimed to analyze the correlation between ultrasound findings related to rectus femoris morphology and composition with sports performance indicators and to analyze sociodemographic, sports performance and ultrasound differences according to playing position. Methods An observational study was conducted at the CFF OLYMPIA soccer club (Madrid, Spain). Twenty-two semi-professional female soccer players were enrolled in this study. Sociodemographic data, bilateral ultrasound measurements of the rectus femoris muscle and sports performance tests (Counter Movement Jump -CMJ-, The Sprint Repeat Ability -SRA-, and one Repetition Maximum -1RM-) were collected. Results No correlations between ultrasound imaging and sports performance indicators were found. Significant correlations between cross-sectional area and perimeter with age (p0.05). Finally, most of the functional tests showed no between-position differences (except SRA between goalkeepers and attackers). Conclusion Although muscle morphology and quality are associated with demographic features, US should not be used as a predictor of sports performance in female football players since no association between US and sports performance were observed. Similar US and functional test scores were obtained among the different playing positions.

Objective: To describe the injury rate, severity, cause, anatomical location (tissue damaged), recurrence, place and time during matches throughout a season in the Spanish Rugby Union Division de Honor. Methods: Observational, prospective and descriptive study conducted in the competition of the Spanish División de Honor de Rugby with 258 players. The data were reported by the medical services of the previously formed clubs. Results: Total exposure was 4100 h, during which 220 injuries occurred. The average number of sick days was 36.8. The total injury rate was 53.6 injuries/1000 h of exposure. Three quarters suffered 93 injuries and the forwards sustained a total of 127 injuries, with a total of 48.6 and 58.1 injuries/1000 h of exposure, respectively. Moderate injuries were the most frequent. Specifically, ligament injury was the most frequent, and dislocation was the injury that caused the most sick days. The most injuries occurred in the third quarter of the match, and the most serious injuries occurred in the second quarter. Conclusions: The injury rate of Spanish rugby competitors is 53.6 injuries/1000 match hours, with an average of 36.8 sick days. Contact injuries are the most frequent, taking place especially when tackling or being tackled.

Background: The aims of this study were to develop a web-based Spanish form of the Barthel index (BI), to evaluate its psychometric properties and stability over time (test-retest), and to determine minimal detectable change (MDC) in patients with multiple sclerosis (MS). Methods: Participants answered the BI on two forms (web-based and face-to-face interview), 7–10 days apart. The internal consistency was evaluated using Cronbach’s alpha, and intraclass correlation (ICC) and kappa (κ) coefficients were used to investigate the agreement between both forms. Results: 143 participants were included. The Spanish web-based form of the BI showed excellent agreement between both forms for each item (κ = 0.86 (0.79 to 0.92), and for total score (κ = 0.87 (0.81 to 0.93); ICC = 0.99 (0.98 to 0.99). The internal consistency was good–excellent (Cronbach’s alpha = 0.89 (0.86–0.91)). The stability over time was adequate, the agreement of each item was κ = 0.63 (0.52–0.74)), and for total score (ICC = 0.97), determining a MDC95 of 12.09 points. Conclusions: The Spanish web-based form of the BI is a valid and reliable tool to assess functionality and can be applied in both formats in patients with MS. A total score difference of more than 12 points was found to indicate a deterioration or improvement in the patient’s functionality.

To determine reference values, including the appropriate number of repetitions, and test-retest reliability of the torsion and conventional cervical joint position sense (JPS) tests.Phase 1) Cross-sectional design to determine reference values and the appropriate number of repetitions; Phase 2) repeated-measures concordance design (test-retest reliability). Sixty-eight healthy participants performed 10 repetitions of randomized rotation left and right for both cervical JPS tests using a laser projected onto a target. Thirty participants returned for the same evaluation process one week later.The age-stratified reference values for the torsion JPS test showed greater absolute error as age increased. Stable levels of performance were obtained with 6-7 repetitions for both tests. Moderate to good reliability was found with 7 or more repetitions for left rotation [Torsion JPS test, Intraclass Correlation Coefficient (ICC; 95% CI) = 0.85 (0.68-0.93); Conventional JPS test, ICC = 0.78 (0.53-0.89)], and 6-7 or more repetitions for right rotation [Torsion JPS test, 6 repetitions, ICC = 0.79 (0.56-0.90); Conventional JPS test, 7 repetitions, ICC = 0.82 (0.61-0.91)]. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) stabilized at 7 repetitions in both tests [Torsion JPS test (SEM ≤ 1.0°; MDCThe reference values generated for the torsion JPS test may help identify the presence of impairments cervical proprioception. At least 7 repetitions optimize stability, reliability and responsiveness in the torsion and conventional cervical JPS tests.

To determine the differences in respiratory muscle strength and pulmonary function between patients with chronic neck pain (CNP) and asymptomatic individuals.Databases were MEDLINE, CINAHL, Scopus, Web of Science and EMBASE up to the end of September 2021. Studies with cross-sectional and longitudinal design were selected, with adult patients with CNP and asymptomatic individuals with reports respiratory function.11 studies met the inclusion criteria and 10 were included in the meta-analysis showing a statistically significant reduction in inspiratory/expiratory muscle strength (MIP/MEP) in the patients with CNP compared with the asymptomatic individuals (mean difference (MD) for MIP, -11.67 [-14.57 to -8.77]; MD for MEP, -11.80 [-14.99 to -8.60]) and pulmonary function: vital capacity (standardized mean difference (SMD), -0.31 [-0.56 to -0.06]); maximum voluntary ventilation (SMD, -0.36 [-0.59 to -0.14]); forced vital capacity (SMD, -0.53 [-0.99 to -0.06]); peak expiratory flow (SMD, -0.58 [-1.03 to -0.12]); and forced expiratory volume in the first second (SMD, -0.28 [-0.51 to -0.05]).Patients with CNP have reduced respiratory muscle strength and pulmonary function compared with asymptomatic individuals, and this difference could be clinically meaningful. However, more studies of high methodological quality and longitudinal studies are needed to strengthen the results of this meta-analysis. IMPLICATIONS FOR REHABILITATIONRespiratory dysfunction has been observed in patients with chronic neck pain.Patients with chronic neck pain present a decrease in respiratory muscle strength and pulmonary function compared with asymptomatic individuals.Respiratory pattern disorders should be considered in the clinical context of chronic neck pain.Interventions focused on respiratory muscle training could be helpful for this population.

The aim of this study was to develop a Spanish Version of the Trunk Measurement Scale (TCMS-S) to analyze its validity and reliability and determine the Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) in children with Cerebral Palsy (CP). Participants were assessed twice 7–15 days apart with the TCMS-S and once with the Gross Motor Function Measurement-88 (GMFM-88), Pediatric Disability Inventory-Computer Adaptive Test (PEDI-CAT), Cerebral Palsy Quality of Life (CPQoL), and Gross Motor Classification System (GMFCS). Internal consistency was evaluated using Cronbach’s alpha, and the intraclass correlation (ICC) and kappa coefficients were used to investigate the agreement between the assessments. Finally, 96 participants with CP were included. The TCMS-S showed excellent internal consistency (Cronbach’s alpha = 0.95 [0.93 to 0.96]); was highly correlated with the GMFM-88 (rho = 0.816) and the “mobility” subscale of the PEDI-CAT (rho = 0.760); showed a moderate correlation with the “feeling about functioning” CPQoL subscale (rho = 0.576); and differentiated between the GMFCS levels. Excellent test–retest agreement was found for the total and subscale scores (ICC ≥ 0.94 [0.89 to 0.97). For the total TCMS-S score, an SEM of 1.86 and an MDC of 5.15 were found. The TCMS-S is a valid and reliable tool for assessing trunk control in children with CP.

Objective: This meta-analysis evaluated the effect of dry needling alone or combined with other treatment interventions on pain, related-disability, pressure pain sensitivity, and strength in people with lateral epicondylalgia of musculoskeletal origin. Data Sources: MEDLINE, CINAHL, PubMed, PEDro, Cochrane Library, SCOPUS and Web of Science databases from their inception to 5 April 2020. Review Methods: Randomized controlled trials collecting outcomes on pain, related-disability, pressure pain thresholds, or strength where one group received dry needling for lateral epicondylalgia of musculoskeletal origin. The risk of bias was assessed by the Cochrane Guidelines, methodological quality was assessed with the PEDro score, and the quality of evidence by using the GRADE approach. Results: Seven studies including 320 patients with lateral epicondylalgia were included. The meta-analysis found that dry needling reduced pain intensity (SMD ‒1.13, 95%CI ‒1.64 to ‒0.62) and related-disability (SMD ‒2.17, 95%CI ‒3.34 to ‒1.01) with large effect sizes compared to a comparative group. Dry needling also increased pressure pain thresholds with a large effect size (SMD 0.98, 95%CI 0.30 to 1.67) and grip strength with a small size effect (SMD 0.48, 95%CI 0.16 to 0.81) when compared to a comparative group. The most significant effect was at short-term. The risk of bias was generally low, but the heterogenicity of the results downgraded the evidence level. Conclusion: Low to moderate evidence suggests a positive effect of dry needling for pain, pain-related disability, pressure pain sensitivity and strength at short-term in patients with lateral epicondylalgia of musculoskeletal origin. Level of Evidence: Therapy, level 1a. Registration number: OSF Registry - https://doi.org/10.17605/OSF.IO/ZY3E8

To evaluate the effects of a home-based respiratory muscle training programme (inspiratory [IMT] or inspiratory/expiratory muscles [RMT]) supervised by telerehabilitation on quality of life and exercise tolerance in individuals with long-term post-COVID-19 symptoms. The secondary objective was to evaluate the effects of these programmes on respiratory muscle function, physical and lung function, and psychological state.88 individuals with long-term symptoms of fatigue and dyspnoea after COVID-19 diagnosis were randomly (1:1 ratio) assigned to IMT, IMTAt post-intervention, there was a statistically significant and large (d0.90) improvement in quality of life, but not in exercise tolerance, in the RMT group compared with the RMTOnly an 8-week supervised home-based RMT programme was effective in improving quality of life, but not exercise tolerance, in individuals with long-term post-COVID-19 symptoms. In addition, IMT and RMT programmes were effective in improving respiratory muscle function and lower limb muscle strength, but had no impact on lung function and psychological status.

This study aimed to analyze if chronic low back pain (LBP) and lumbar disc herniation induce biomechanics, flexibility, body balance, physical activity, and muscular function alterations compared to a similar asymptomatic cohort. Fifty male volunteers (n = 25 with chronic LBP and lumbar disc herniation and n = 25 pain-free subjects) were enrolled. Range of motion (internal and external hip rotation, ankle dorsiflexion, and active straight leg raise, ASLR), trunk flexibility (finger–floor distance), body balance (Y-balance test) and muscle function (Biering–Sorensen test, prone and lateral bridges) outcomes were assessed. Comparative analyses between sides and group were conducted. Results: Patients showed greater weight and BMI compared with controls (p < 0.05). None of the outcomes bilaterally assessed showed side-to-side differences for pain-free participants (all, p > 0.05) or LBP patients (all, p > 0.05). Regarding the differences between groups, LBP patients showed limited internal hip rotation (p < 0.001), finger–floor distance (p < 0.001), body balance (p < 0.001), and muscle endurance (planks p < 0.001; Biering–Sorensen test p < 0.05). External hip rotation, ASLR, and ankle dorsiflexion range of movement were comparable in both groups (p > 0.05). The sample of pain-free amateur athletes showed greater range of movement for internal hip rotation, lower finger–floor distance, better body balance, and muscle function. However, the external hip rotation, ankle dorsiflexion, and ASLR tests showed no difference between cases and controls.

To investigate the health-related quality of life (HRQoL), symptoms, psychological and cognitive state and pulmonary and physical function of nonhospitalised COVID-19 patients at long-term, and to identify factors to predict a poor HRQoL in this follow-up.Studies have focused on persistent symptoms of hospitalised COVID-19 patients in the medium term. Thus, long-term studies of nonhospitalised patients are urgently required.A longitudinal cohort study.In 102 nonhospitalised COVID-19 patients, we collected symptoms at 3 months (baseline) and at 6-7 months (follow-up) from diagnosis (dyspnoea, fatigue/muscle weakness and chest/joint pain), HRQoL, psychological state, cognitive function, pulmonary and physical function. This study adhered to the STROBE statement.HRQoL was impaired in almost 60% of the sample and remained impaired 6-7 months. At 3 months, more than 60% had impaired physical function (fatigue/muscle weakness and reduced leg and inspiratory muscle strength). About 40%-56% of the sample showed an altered psychological state (post-traumatic stress disorder (PTSD), anxiety/depression), cognitive function impairment and dyspnoea. At 6-7-months, only a slight improvement in dyspnoea and physical and cognitive function was observed, with a very high proportion of the sample (29%-55%) remained impaired. Impaired HRQoL at 6-7 months was predicted with 82.4% accuracy (86.7% sensitivity and 83.3% specificity) by the presence at 3 months of muscle fatigue/muscle weakness (OR = 5.7 (1.8-18.1)), PTSD (OR = 6.0 (1.7-20.7)) and impaired HRQoL (OR = 11.7 (3.7-36.8)).A high proportion of nonhospitalised patients with COVID-19 experience an impaired HRQoL, cognitive and psychological function at long-term. HRQoL, PTSD and dyspnoea at 3 months can identify the majority of patients with COVID-19 who will have impaired quality of life at long-term.Treatments aimed at improving psychological state and reducing the fatigue/muscle weakness of post-COVID-19 patients could be necessary to prevent the patients' HRQoL from being impaired at 6-7 months after their reported recovery.

Background: The goal of this study was to analyze psychometric properties of the Spanish PROMIS Pediatric Pain Interference short form (PROMIS-PPI) in a sample of Spanish children and adolescents. Methods: In a hospital pediatric sample itwas studied the structure scale (exploratory and confirmatory analysis), construct validity, convergent validity, and reliability (internal consistency). Findings: 163 children and adolescents (mean age 13.3 years; SD 2.01; 39.26% female) with and without chronic pain completed measures pertaining to their pain experience. Psychometric analysis showed the PROMIS-PPI Spanish version maintains the original one-factor model of the scale, excellent internal consistency (Cronbach's α coefficient 0.90 (95% CI 0.88–0.92)), and convergent validity (showed a positive, significant, and moderate magnitude correlation [r from 0.330 to 0.604] with pediatric quality of life, child and parent pain intensity, and showed a low correlation with the number of medical consultations in the last year). Discussion: The Spanish PROMIS-PPI scale is a valid and reliable tool. It is recommended for research and clinical care in pediatric populations. Application to practice: The results provide evidence that the Spanish version of PROMIS-PPI is valid and reliable tool. Health professionals who work with children in risk to develop persistent pain, will have access to short tool with highest evidence, for assess pain interference.

Previous evidence showed altered lumbar multifidus (LM) activation in populations with chronic nonspecific low back pain (LBP). We aimed to investigate the test-retest and inter-examiner reliability of ultrasound imaging (US) for assessing LM thickness at rest and activation during the active straight leg raise test (ASLR) and the association between thickness changes with clinical outcomes.Fifty-two patients with LBP and two examiners (one experienced and one novice) participated in this study. A total of 18 B-mode images at L4-L5 or L5-S1 level (both sides, 3 at rest and 6 during ASLR) were collected. For assessing test-retest reliability, the experienced examiner repeated the procedure after 7 days. Intraclass correlation coefficients (ICC), standard error of measurements (SEM) and minimal detectable changes (MDC) were calculated.Inter-examiner agreement was good to excellent (ICC3,2 = 0.71-0.92) and test-retest reliability was excellent (ICC3,1 = 0.91-0.98). Mean average of multiple measurements improved the agreement. Greater LM thickness at rest (p .05) and greater thickness change after 3 s (p .01) and 10 s (homolateral side, p .01; contralateral side, p .05) were associated with less pain intensity.US is a reliable method to assess the LM thickness at rest and contracted during the ASLR in patients with LBP. The measurement at 3 s after maintaining ASLR, as well as the use of the mean of three measurements, has been shown to be the most reliable method for measuring LM muscle thickness during ASLR.

Altered lumbar multifidus (LM) activation has been found in populations with non-specific chronic low back pain (NSCLBP).To detect differences in LM muscle thickness at rest and during active manoeuvres between patients with NSCLBP and pain-free controls and to analyze the ability of LM thickness change during the active straight leg raise (ASLR) with rehabilitative ultrasound imaging to detect patients with NSCLBP.Cross-sectional observational study.Seventy volunteers (50% patients NSCLBP) were recruited. 18 B-mode images of LM at L4-L5 or L5-S1 level selecting the most symptomatic level (both sides, six at rest and three during ASLR) were collected by a blinded assessor. Differences between patients and controls in LM muscle thickness at rest, during ASLR (holding 3sec), and 5 s after ASLR were calculated. In addition, discriminant validity was evaluated by calculating the area under the receiver operating characteristic curve (ROC), sensitivity, specificity and positive and negative likelihood ratio.Significant LM thickness change differences during ASLR were found within and between groups: bilaterally, LM thickness change during ASLR was significantly higher in healthy controls than in NSCLBP patients. Ipsilateral LM muscle thickness change was sensitive to detect individuals with NSCLBP (ROC = 0.79-0.80).Pain-free individuals exhibited significantly greater LM thickness changes bilaterally during the ASLR compared to patients with NSCLBP. LM thickness change during the ASLR has good validity for discriminating patients with NSCLBP. Further studies should assess benefits of LM training programs in the management of these patients.

Objectives To assess the psychometric characteristics of the Spanish Post-COVID-19 Functional Status (PCFS) scale (web-based and paper-based forms) and the test-retest reliability of the web-based form. Study design and setting Cross-sectional study of 125 COVID-19 survivors. The test-retest reliability of the web-based form was assessed at 7 days after the first evaluation. We collected symptoms, functional status (PCFS scale), health-related quality of life (EuroQol-5D questionnaire, EQ-5D-5L), activities of daily living limitations [Barthel Index and Global Activity Limitation Index, GALI] and psychological state (Hospital Anxiety and Depression Scale, HADS). Results The paper- and web-based forms of the Spanish PCFS scale showed adequate construct validity, and the web-based form provided substantial test-retest reliability (kappa = 0.63). The percentage of agreement between the web-based and paper-based forms was high (88%). Functional status showed a high correlation with EQ-5D-5L (inverse) and GALI (direct) (both; Rho ≥ .743), a moderate correlation with HADS (Rho ≥ .409) and a low correlation with the Barthel Index (Rho < .30). The Kruskal–Wallis test showed statistically significant differences in EQ-5D-5L, GALI and HADS according to the degree of functional status. Conclusion The Spanish version of the PCFS scale (web-based and paper-based forms) showed adequate construct validity, and the web-based form provided substantial test-retest reliability in COVID-19 survivors.

Simpler and less expensive field tests, such as the 6-min walk test, have been employed to evaluate exercise tolerance in chronic paediatric conditions. However, patterns of longitudinal change for outcome measures could show initial gains attributable to normal growth and development in children. We aimed to verify the effect of growth on the distance achieved in 6-min walk test in children 6 to 12 years of age over a 4-month period. Healthy children from 6–12 years of age were recruited. Two trials of the 6-min walk test were performed on the same day and after a 4-month period. We employed the intraclass correlation coefficient to assess test-retest reliability when the 6-min walk test was applied with a 4-month time interval. 59 children (28 boys and 31 girls) were assessed. The distance covered in the 6-min walk test and anthropometric variables showed a statistically significant increase after 4 months. After 4 months, we established a 12% change from the initial measurement (79.69 m) as the minimal detectable change for a 90% confidence level, while a 15% change (94.66 m) was determined as the minimal detectable change for a 95% confidence level. Conclusions: The distance covered in the 6-min walk test improved as the children’s height increased, establishing a 12% change in the score of at least 79.69 m as the most appropriate value in interpreting longitudinal functional performance data when assessing exercise tolerance in healthy children aged 6 to 12 years.

This systematic review aims to analyze the validity and reliability of available tools to assess health-related quality of life (HRQoL) and exercise tolerance in children and adolescents with cystic fibrosis (CF).A review of observational studies studying the validity and reliability of the tools was conducted. The COSMIN (COnsesus-based Standards for the selection of health Measurements INstruments) guide was followed to analyze the quality of these tools.A total of 18 studies were selected. Of the eight HRQoL tools, five generic and three specific, analyzed in 14 studies, the Cystic Fibrosis Questionnaire-Revised (CFQ-R) presents the best properties. Of the four tools analyzed to assess exercise tolerance, cycle ergometry and the modified shuttle test are the most valid and reliable.The CFQ-R, cycloergometry and the modified shuttle test have the best properties for the assessment of children with CF, but more studies are needed.

The abdominal drawing-in maneuver (ADIM) is a clinical tool used for identifying preferential activity of deep abdominal muscles. However, concurrent validity and reproducibility of palpation during the ADIM has not been formally investigated. The aims of this study were (1) to assess intra- and interrater reliability of manual palpation during the ADIM, and (2) to determine the concurrent validity of manual palpation during the ADIM by calculating preferential activation ratio cut-off as assessed with ultrasound imaging (RUSI). Thirty-two subjects (n = 16 patients with nonspecific low back pain and 16 comparable healthy individuals) performed the ADIM in a supine hook-lying position. Two experienced assessors evaluated the presence or absence of preferential contraction of the deep abdominal muscles by palpation during the ADIM on 2 different days. Intrarater (test-retest) and interrater reliability of palpation were calculated using Cohen’s kappa coefficients. Muscle thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles at rest and during the ADIM were also measured. TrA-Contraction Ratio (TrA-CR), TrA-Preferential Activation Ratio (TrA-PAR), and Modified-TrA-PR (M-TrA-PAR) were calculated. The concurrent validity of manual palpation was determined using the correlation between manual palpation and imaging and by calculating ROC curve (operating characteristics curve), Youden index, and sensitivity and specificity. Intra- and interrater reliability of manual palpation during the ADIM was excellent (k: 0.82–1.00) and good to excellent (k: 0.71–1.00), respectively. Interrater reliability for muscle thickness ranged from good to excellent (ICC3,1 0.79–0.91). Manual palpation and TrA ratio showed low to moderate correlations (r: 0.36–0.60). When evaluating the diagnostic accuracy of manual palpation, the best predictive model (ROC value: 0.89, p &lt, 0.001) for correct a preferential contraction of TrA was obtained when the M-TrA-PAR was ≥0.08 (sensitivity: 0.95–1.00, specificity: 0.62). Good to excellent intra- and interrater reliability of manual palpation was found during the ADIM in both patients and healthy groups. Manual palpation showed concurrent validity for identifying the preferential activity of the TrA muscle supporting its use in clinical practice.

Objective. To evaluate the effects of combining dry needling with other physical therapy interventions versus the application of the other interventions or dry needling alone applied over trigger points (TrPs) associated to neck pain. Databases and Data Treatment. Electronic databases were searched for randomized controlled trials where at least one group received dry needling combined with other interventions for TrPs associated with neck pain. Outcomes included pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion. The risk of bias (RoB) was assessed using the Cochrane risk of bias tool, methodological quality was assessed with PEDro score, and the quality of evidence was assessed by using the GRADE approach. Between-groups mean differences (MD) and standardized mean difference (SMD) were calculated. Results. Eight trials were included. Dry needling combined with other interventions reduced pain intensity at short-term (SMD −1.46, 95% CI −2.25 to −0.67) and midterm (SMD −0.38, 95% CI −0.74 to −0.03) but not immediately after or at long-term compared with the other interventions alone. A small effect on pain-related disability was observed at short-term (SMD −0.45, 95% CI −0.87 to −0.03) but not at midterm or long-term. The inclusion of dry needling was also effective for improving pressure pain thresholds only at short-term (MD 112.02 kPa, 95% CI 27.99 to 196.06). No significant effects on cervical range of motion or pain catastrophism were observed. Conclusion. Low-to-moderate evidence suggests a positive effect to the combination of dry needling with other interventions for improving pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion in people with neck pain associated with TrPs at short-term. No midterm or long-term effects were observed.

Objectives To generate normative data on healthy children aged 6–14 years for the timed up and down stairs (TUDS) test, and to provide reference equations. Design and setting Cross-sectional study at two primary schools. Participants Healthy children 6–14 years of age. Main outcomes measures Anthropometric data and Minnesota Leisure-Time Physical Activity Questionnaire from children were collected before the start of the TUDS test. Heart rate, blood pressure and perceived exertion were measured at the beginning and at the end of the test. Two trials of the TUDS test were performed with 15-minute of rest on the same day and the better of the two trials was used in the analyses. The reference equations were established using the anthropometric variables as possible predictors of the TUDS test. Results Two hundred fifty eight children (125 boys and 133 girls) were assessed. The mean TUDS test score decreased significantly from 6 to 14 years of age in boys and girls alike, with statistically significant differences between the three age range groups. A significant difference was found between girls and boys in TUDS test score. The 56% of the variation in TUDS test score could be explained by age, height, and weight in boys [TUDSsec score = (9.967 − (0.182 × Ageyears) + (0.025 × Weightkg) − (2.546 × Heightm)], while 50% could be explained in girls [TUDSsec score = 10.553 − (0.194 × Ageyears) + (0.019 × Weightkg) − (2.406 × Heightm)]. The inclusion of physical level activity increased the variability explained (boys: 59%; girls: 51%). Conclusions TUDS score improved as the age of the children increased, with boys achieving better values than girls within each age group. TUDS test score can be easily predicted from age, height, and weight. The inclusion of the child's physical activity level increased the variance explained by the equation.

(de Asís-Fernández F, del Corral T, López-de-Uralde-Villanueva I. Effects of inspiratory muscle training versus high intensity interval training on the recovery capacity after a maximal dynamic apnoea in breath-hold divers. A randomised crossover trial. Diving and Hyperbaric Medicine. 2020 December 20;50(4):318–324. doi: 10.28920/dhm50.4.318-324. PMID: 33325010.) Introduction: After a maximal apnoea, breath-hold divers must restore O2 levels and clear CO2 and lactic acid produced. High intensity interval training (HIIT) and inspiratory muscle training (IMT) could be employed with the aim of increasing recovery capacity. This study aimed to evaluate the relative effects of IMT versus HIIT on recovery of peripheral oxygen saturation (SpO2), and also on pulmonary function, inspiratory muscle strength, lactate and heart rate recovery after a maximal dynamic apnoea in breath-hold divers. Methods: Fifteen breath-hold divers performed two training interventions (IMT and HIIT) for 20 min, three days per week over four weeks in randomised order with a two week washout period. Results: IMT produced a > 3 s reduction in SpO2 recovery time compared to HIIT. The forced expiratory volume in the first second (FEV1) and maximum inspiratory pressure (MIP) were significantly increased in the IMT group compared to HIIT. The magnitude of these differences in favour of IMT was large in both cases. Neither training intervention was superior to the other for heart rate recovery time, nor in peak- and recovery- lactate. Conclusions: IMT produced a reduction in SpO2 recovery time compared to HIIT after maximal dynamic apnoea. Even a 3 s improvement in recovery could be important in scenarios like underwater hockey where repetitive apnoeas during high levels of exercise are separated by only seconds. IMT also improved FEV1 and MIP, but no differences in lactate and heart rate recovery were found post-apnoea between HIIT and IMT.

Objectives The objective was to explore whether action observation (AO) and motor imagery (MI) of aerobic and isometric exercise could induce hypoalgesic responses in asymptomatic individuals compared with placebo observation (PO). Methods A randomized controlled pilot trial was designed. Twenty-four healthy participants (mean age = 21.9 ± 2.1 years) were randomized into three groups: AO+MI (N = 8), AO, (N = 8), and PO (N = 8). All participants performed an actual aerobic running exercise (three series of 90 seconds at 85% of their VO2max and 30 seconds at 65% of their VO2max) and an isometric exercise protocol (isometric squats). A day later, they all performed the mental intervention, observing or imagining exercise execution performed the day before, according to their allocated group. Pressure pain thresholds (PPTs) of the quadriceps and epicondyle regions were assessed at baseline, postintervention, and 15 minutes postintervention. Results Analysis of variance revealed statistically significant differences in the group*time interaction for PPT in the quadriceps. The AO group showed a statistically significant increase at postintervention and at 15 minutes postintervention. The AO+MI group obtained a statistically significant increase in the two PPT regions compared with the PO group at Δpre–post. The AO group obtained a greater increase in the PPT in the quadriceps femoris than the PO group at Δpre–post and Δpre–post 15 minutes. Conclusions AO and MI induce hypoalgesic responses compared with PO. AO isolated training showed pain modulation responses in the PPTs of the quadriceps region in young physically active adults. These findings highlight the potential role of brain training in pain management.

Resumen: Introducción: La escala autoadministrada de Evaluación de Signos y Síntomas Neuropáticos de Leeds (S-LANSS) es un instrumento diseñado para identificar a pacientes con dolor de características neuropáticas. Objetivo: Evaluar la validez y fiabilidad de la versión española del S-LANSS. Métodos: Se incluyó un total de 182 pacientes con dolor crónico para evaluar la validez discriminante y convergente del S-LANSS, incrementándose la muestra hasta 321 pacientes para valorar la validez de constructo y la fiabilidad de la escala. Se utilizó como variable criterio la versión validada al español del ID-Pain. Todos los participantes cumplimentaron el cuestionario ID-Pain, el S-LANSS, y la Escala Numérica del Dolor. La validez discriminante se evaluó mediante el análisis del área bajo la curva de características operativas para el receptor, y la sensibilidad y especificidad. La validez de constructo se evaluó mediante un análisis factorial y mediante el análisis del odds-ratio de cada ítem del S-LANSS respecto a la puntuación total. La validez convergente y la fiabilidad se valoraron con la R de Pearson y el alfa de Cronbach respectivamente. Resultados: El punto de corte óptimo del S-LANSS fue ≥ 12 puntos (área bajo la curva = 0,89; sensibilidad = 88,7; especificidad = 76,6). El S-LANSS presentó un factor y, además, cada ítem contribuyó significativamente a la puntuación total positiva del S-LANSS (p

OBJECTIVE Subjects with greater trochanteric pain syndrome (GTPS) show an altered physical function while performing static and dynamic tasks. Pain and psychosocial factors are also variables that influence the outcomes of these patients. Thus, the aim of this study was to evaluate the relationship between dynamic balance, pain-related measures, and psychosocial measures in subjects with chronic GTPS. DESIGN Descriptive cross-sectional study. SETTING Primary health care center. SUBJECTS Fifty-one subjects with greater trochanteric pain syndrome were recruited. METHODS Dynamic balance was evaluated using the Y-Balance Test (YBT), and a self-reported test battery was used to assess the following aspects: pain catastrophizing (Pain Catastrophizing Scale [PCS]), kinesiophobia (Tampa Scale of Kinesiophobia [TSK-11]), pain intensity (visual analog scale [VAS]), disability (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), and self-efficacy (Chronic Pain Self-Efficacy Scale [CPSS]). RESULTS Correlation analysis showed that YBT was negatively associated with the VAS average, the helplessness subscale of the PCS, and the pain and function subscales and total score of the WOMAC. YBT was positively associated with the pain subscale of the CPSS. The scores of the YBT forward movement were predicted by the VAS average (38.1% of variance) in addition to the WOMAC total score (34.2% of variance) and TSK-11 total score (43.8% of variance). CONCLUSIONS The findings of this study suggest that kinesiophobia, pain, and physical function are related to dynamic balance in subjects with GTPS. Thus, when diagnosing and planning the treatment of patients with GTPS, psychosocial and physical function factors should be taken into account, in addition to pain management.

Thanks to advances in neuroscience, biopsychosocial models for diagnostics and treatment (including physical, psychological, and pharmacological therapies) currently have more clinical support and scientific growth. At present, a conservative treatment approach prevails over surgery, given it is less aggressive and usually results in satisfactory clinical outcomes in mild-moderate temporomandibular disorder (TMD). The aim of this review is to evaluate the recent evidence, identify challenges, and propose solutions from a clinical point of view for patients with craniofacial pain and TMD. The treatment we propose is structured in a multi-modal approach based on a biobehavioral approach that includes medical, physiotherapeutic, psychological, and dental treatments. We also propose a new biobehavioral model regarding pain perception and motor behavior for the diagnosis and treatment of patients with painful TMD.

The objective of this study was to evaluate whether the addition of manual therapy and therapeutic exercise protocol to inspiratory muscle training was more effective in improving maximum inspiratory pressure than inspiratory muscle training in isolation.This is a single-blinded, randomized controlled trial.In total, 43 patients with asthma were included in this study.The patients were allocated into one of the two groups: (1) inspiratory muscle training ( n = 21; 20-minute session) or (2) inspiratory muscle training (20-minute session) combined with a program of manual therapy (15-minute session) and therapeutic exercise (15-minute session; n = 22). All participants received 12 sessions, two days/week, for six weeks and performed the domiciliary exercises protocol.The main measures such as maximum inspiratory pressure, spirometric measures, forward head posture, and thoracic kyphosis were recorded at baseline and after the treatment.For the per-protocol analysis, between-group differences at post-intervention were observed in maximum inspiratory pressure (19.77 cmHThe inspiratory muscle training combined with a manual therapy and therapeutic exercise program is more effective than its application in isolation for producing short-term maximum inspiratory pressure and forward head posture improvements in patients with asthma.

Background The Passive Neck Flexion Test (PNFT) can diagnose meningitis and potential spinal disorders. Little evidence is available concerning the use of a modified version of the PNFT (mPNFT) in patients with chronic nonspecific neck pain (CNSNP). Objectives To assess the reliability of the mPNFT in subjects with and without CNSNP. The secondary objective was to assess the differences in the symptoms provoked by the mPNFT between these two populations. Design We used repeated measures concordance design for the main objective and cross-sectional design for the secondary objective. Method A total of 30 asymptomatic subjects and 34 patients with CNSNP were recruited. The following measures were recorded: the range of motion at the onset of symptoms (OS-mPNFT), the range of motion at the submaximal pain (SP-mPNFT), and evoked pain intensity on the mPNFT (VAS-mPNFT). Results Good to excellent reliability was observed for OS-mPNFT and SP-mPNFT in the asymptomatic group (intra-examiner reliability: 0.95–0.97; inter-examiner reliability: 0.86–0.90; intra-examiner test-retest reliability: 0.84–0.87). In the CNSNP group, a good to excellent reliability was obtained for the OS-mPNFT (intra-examiner reliability: 0.89–0.96; inter-examiner reliability: 0.83–0.86; intra-examiner test-retest reliability: 0.83–0.85) and the SP-PNFT (intra-examiner reliability: 0.94–0.98; inter-examiner reliability: 0.80–0.82; intra-examiner test-retest reliability: 0.88–0.91). The CNSNP group showed statistically significant differences in OS-mPNFT (t = 4.92; P P = 0.007) and in VAS-mPNFT (t = −10.39; P Conclusion The mPNFT is a reliable tool regardless of the examiner and the time factor. Patients with CNSNP have a decrease range of motion and more pain than asymptomatic subjects in the mPNFT. This exceeds the minimal detectable changes for OS-mPNFT and VAS-mPNFT.

Background There is a lack of evidence to assess whether gait functionality can be affected by the condition of the pelvic floor musculature in patients with multiple sclerosis (MS). Objective To evaluate the relationship between pelvic floor functionality and general functional performance, and also their relationship depending on dependence degree in MS patients. Participants Forty-three MS patients performed the study. The pelvic floor musculature and its functionality were evaluated by urinary incontinence (UI), fecal incontinence, and constipation. General functional performance was evaluated by the Barthel index, the Health Status Questionnaire Short Form-12 (SF-12), and the Timed Up and Go (TUG) test. Results UI was moderately related to general functional performance (SF-12 Physical: R = -0.413; Barthel index: R = -0.501; TUG: R = 0.482). The comparative analysis showed differences between UI and gait functionality (P = .008), with poorer results in the TUG in patients with moderate/severe dependence (P Conclusion UI appears to have a negative impact on the performance of daily living activities, walking, and the physical dimension of quality of life in patients with MS. In addition, patients with moderate or severe dependence showed higher UI and gait disturbance compared with those with mild dependence or independence.

Background: Multiple sclerosis (MS) is an autoimmune, chronic and inflammatory disease characterized by an axonal loss that may be accompanied by respiratory muscle weakness. Objective: The aim of this study was to assess pulmonary function and respiratory muscle strength in MS patients and to identify differences between gender. Methods: This prospective, noninterventional study measured respiratory parameters in patients with MS by maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) of the mouth, sniff nasal inspiratory pressure (SNIP) and lung capacity using a forced spirometry. Results: A total of 28 patients with MS (mean (SD) men (n=13) 50.7 ± 7.4 years; women (n= 15) 50 ± 9.9 years) were included. Both groups presented respiratory dysfunction showing values Conclusions: MS patients showed a decrease in pulmonary function and respiratory muscle weakness. This study found that women with MS have lower values in these parameters than men.

Objective The purpose of this study was to develop a scale to measure patient adherence to physical therapist intervention and to report psychometric properties in patients with cystic fibrosis (CF). Methods This observational, multicenter, qualitative, and cross-sectional study was divided into 2 phases: development of scale items (content validity) and assessment of psychometric properties (construct validity, reliability, and convergent/discriminant validity). Recruited were 121 patients with CF (aged ≥16 years). Sociodemographic characteristics, lung function testing, Coping with Stress Self-Efficacy, brief Coping Orientation to Problems Experienced inventory, and the scale of Adherence to Treatment of Physiotherapy (AdT-Physio) scale were evaluated. Results The final version of the AdT-Physio scale consists of 15 items distributed across 2 subscales: compliance and beliefs about treatment/therapist. The scale showed high internal consistency (Cronbach α = .897; 95% CI = 0.868–0.922) and subscales above 0.800. The 2-factor confirmatory factor analysis model fitted the data reasonably well: χ2 (76) = 111.96, comparative fit index = 0.982, Tucker-Lewis index = 0.978, root mean square error of approximation = 0.063, 95% CI = 0.036 to 0.086, and weighted root mean square residual = 0.720. No floor or ceiling effects were identified. There was a positive, significant, and moderate-low magnitude correlation with the total Coping Orientation to Problems Experienced inventory (r = .360) and Coping with Stress Self-Efficacy subscale efficacy expectations scores (r = .304). For discriminant validity, there was a positive, significant, and moderate correlation between the total and the age of the patients (r = .354). Conclusions The AdT-Physio scale is psychometrically valid and reliable for use in the clinic for the assessment of adherence to physical therapy in patients with CF. Impact Ultimately, the authors propose this documentary instrument to assess the evaluation of the therapeutic alliance in a valid and objective manner. The AdT-Physio scale provides us with a greater degree of understanding of the problems behind noncompliance with treatment to advance person-centered decisions in physical therapy and thereby enhance the effectiveness of care.
