Objectives: This study aims to examine the association of time to recovery between early versus late presentation to outpatient community-based concussion management clinics following sport-related concussion (SRC) among adolescent Canadian athletes., Methods: Using electronic health records (between January 2017 and December 2019) from the Complete Concussion Management Inc (CCMI) database, this was a historical cohort study of Canadian athletes aged 12-18 presenting for care early (0-7 days) or late (8-28 days) after SRC. Time-to-recovery was defined as the date of clinician clearance to return to sport. Propensity scores were first derived from logistic regression with early versus late clinical presentation as the outcome. Cox proportional hazards regression analysis was then used to model the relationship between early versus late clinical presentation and time to recovery, while including the propensity score to adjust for confounding. The association was expressed using hazard rate ratios (HRR) with 95% CIs., Results: A total of 4696 patient records (mean age of 14.71 (±1.69 SD); 57.7% male) were eligible. Early presentation to a concussion management clinic following SRC was associated with faster time to recovery (adjusted HRR 1.23; 95% CI 1.14 to 1.32, p<0.001). This association was consistent within each quintile of the propensity score. The median time to recovery was 18 versus 22 days in the early and late groups, respectively., Conclusion: Adolescent athletes with SRC have favourable recovery trajectories when presenting for care up to 28 days. Time to recovery (clinician clearance to return to sport) may be quicker with an earlier presentation which can lead to a faster return to sport., Competing Interests: CM is the founder and current president of Complete Concussion Management Inc.

Objectives: To investigate the prevalence of spine symptoms and spine disability, self-care and care seeking behaviors in a random sample of Indigenous adults residing in Cross Lake, northern Manitoba, Canada., Study Design and Setting: Orally administered survey in Cree or English to a representative sample of Pimicikamak citizens from the treaty ( n  = 150/1931 houses) and non-treaty ( n  = 20/92 houses) land, between May and July 2023. Questions ( n  = 154) were derived from the 2018 First Nations Regional Health Survey, 2020 Canadian Community Health Survey, and 2021 The Global Burden of Disease study, covering demographics, spine symptoms, chronic conditions, activity limitations, general health, self-care, medication, and satisfaction with care. We used descriptive and cross-tabulations and consulted the community for data interpretation., Results: The survey was completed by 130 adults (65 % females, mean age, 48.4 years). Nearly all participants (89.6 %) reported having spine symptoms in the past four weeks, with a majority experiencing activity limitations lasting one day or more due to neck (77.9 %) or low back pain (55.6 %). Chronic neck and low back pain "sometimes or often" limited activities of daily living (52.8 % and 74.1 % respectively). Nearly two-third (65.4 %) did not have concomitant mood problems. Future preferred care included self-care (88.5 %), over-the- counter medication (64.6 %), seeing an allied care provider (45.4 %), a traditional healer (26.2 %), a nurse or a medical doctor (22.3 %)., Conclusion: Spine symptoms were highly prevalent and significantly impacted activities of daily living. Nearly half of respondents felt that they could benefit from care provided by allied health providers., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Andre Bussieres reports financial support and administrative support were provided by Health Canada.

Background: Chiropractors and chiropractic students commonly report low back pain (LBP). However, the burden of LBP in this occupational group has not been synthesized in the literature. This systematic review aims to describe the epidemiology of LBP in chiropractors and chiropractic students., Methods: We searched MEDLINE, Embase, CINAHL, and PsycINFO from inception to May 1, 2023. Eligible studies were cross-sectional, cohort, or case-control studies investigating the prevalence, incidence, associated factors, or risk factors of LBP in chiropractors or chiropractic students. Reviewers independently screened articles and assessed risk of bias using the appropriate JBI Checklists for the observational study design. We descriptively synthesized studies that were rated as low or moderate risk of bias., Results: Of 2012 citations screened, we included 2 cross-sectional studies in the evidence synthesis (1 study rated as moderate risk of bias on chiropractors, and 1 rated as low risk of bias on chiropractic students). For chiropractors, the 12-month prevalence of work-related overuse injuries to the low back was 35.6% (95% CI 29.1, 42.0) in women and 22.4% (95% CI 16.3, 29.6) in men. The 12-month prevalence of work-related acute physical injuries to the low back in chiropractors were 3.4% (95% CI 1.6, 6.8) for women and 0.7% (95% CI 0.1, 3.7) for men. Among chiropractic students, the 1-week prevalence of LBP was 69% (95% CI 64.8, 73.0). This was higher among female students (72.5%, 95% CI 67.1, 77.4) and lower among male students (64%, 95% CI 57.0, 70.6)., Conclusion: There is limited high-quality evidence on the epidemiology of LBP in chiropractors and chiropractic students. Our systematic review provides a synthesis of the body of literature, highlighting that chiropractors and chiropractic students commonly report LBP. Future high-quality research is needed to address the incidence, associated factors, and risk factors of LBP., Competing Interests: Declarations.

Background: Despite increases in musculoskeletal disorders (MSD) in Canada, evidence suggests utilization of chiropractic services has remained relatively stable over time. Understanding the extent to which chiropractors are consulted and factors associated with their utilization may suggest factors related to accessing care. We assessed the change in prevalence and characteristics of Canadians seeking chiropractic care across two time periods 2001-2010 and 2015-2018., Methods: We used national cross-sectional data from seven cycles of the Canadian Community Health Survey between 2001 and 2018. The survey included Canadians aged 12 years and older living in private dwellings in all provinces and territories. National annual weighted prevalence and age-standardized weighted prevalence (and 95% confidence intervals) of chiropractic utilization were calculated. We calculated prevalence of chiropractic utilization stratified by demographic, socioeconomic, lifestyle and health-related variables. Crude linear trends and change in prevalence from 2001 to 2010 were assessed using linear regression models., Results: The national annual prevalence of Canadians consulting a chiropractor in the previous 12 months slightly increased from 11.0% (95% CI 10.8, 11.3) in 2001 to 11.4% (95%CI 11.1, 11.7) in 2010, and in those reporting receiving regular health care from a chiropractor from 7.5% (95%CI 7.2, 7.7) in 2015 to 7.9% (95%CI 7.7, 8.2) in 2018. Prevalence of utilization varied by province, highest in the Western provinces but lowest in Atlantic provinces. The age-specific prevalence of chiropractic utilization was highest in those aged 35-49 years and remained stable over time, except for slight increase in those aged 65-79 years. A higher percentage of Canadians identifying as white, Canadian-born, in the highest quintile of household income, overweight, physically active and in excellent health reported seeking chiropractic services. The most common reported chronic conditions measured in the survey among Canadians consulting chiropractors were chronic back problems, arthritis, fibromyalgia and headaches., Conclusion: The national prevalence of utilization of chiropractic services among Canadians slightly increased over time but varied by province and respondents' socioeconomic and health characteristics. Chronic back problems were the most common reported chronic condition. This comprehensive population-based study on chiropractic utilization in Canada can be used to inform decisions concerning health human resources and access to rehabilitation care for MSD., (© 2024.

Objective: The purpose of this review was to identify assessment instruments and their measurement properties for assessing evidence-based practice (EBP) knowledge, skills, attitudes, and behavior among students of manual therapy education programs., Methods: 7 electronic databases were systematically searched from inception to May 19, 2023. (MEDLINE, EMBASE, CINAHL, ERIC, EBSCO Discovery, LISA, Google Scholar.) Search terms were subject headings specific to each database (MeSH in MEDLINE) and relevant to evidence-based practice, assessment tools/instruments, and manual therapy healthcare professions. Eligible studies included students of manual therapy education programs (chiropractic, physiotherapy, occupational therapy, osteopathy) and provided evidence supporting instrument measurement properties (reliability, validity). Titles and abstracts were screened by 2 reviewers. Data on each instrument and its properties were extracted and tabulated by 2 reviewers. Instruments were compared using the Classification Rubric for EBP Assessment Tools in Education (CREATE) framework including the 5 steps in the EBP model. Joanna Briggs Institute methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist were followed., Results: 5 studies were identified, (3 physiotherapy, 2 chiropractic) Two studies used a physiotherapy-focused modification of the Fresno test. One study presented the Knowledge of Research Evidence Competencies instrument. Two studies presented original instruments. Instruments focused on the knowledge domain and did not assess all 5 EBP model steps., Conclusion: The current literature does not address all 5 steps of the EBP model. The identified instruments have the potential to ensure chiropractic institutions are graduating chiropractors who are highly skilled in evidence-based practice., (© 2024 Association of Chiropractic Colleges.)

Musculoskeletal (MSK) conditions are the leading cause of disability, resulting in up to 40% of visits to family physicians. Current primary care workforce shortages in Canada require other providers to maximize scopes of practice. Few MSK providers have been trained in team-based primary care settings. Study objectives included: (1) educating participating primary care teams through synchronous education, (2) educating Canadian primary care providers through asynchronous education, and (3) integrating chiropractors into primary care teams, whilst evaluating team MSK care knowledge/attitudes and integration experience. Results indicated improvements in collaborative competency, improved understanding and attitudes to chiropractic, and the importance of providing MSK care within funded primary care. Teams employed unique approaches to integrating chiropractors and indicated high demand for their services by patients and providers. Provision of MSK care without economic barrier is desirable and highly valued by teams. Chiropractors are well suited to participate in funded primary care teams in Canada., Competing Interests: Declaration of conflicting interestsThe author declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The aim of our study is to inform the development of a rehabilitation program of care from the perspectives of those suffering from degenerative cervical radiculopathy (DCR)., Material and Methods: We conducted a qualitative study, purposefully recruiting individuals with DCR. Transcripts from virtual semi-structured interviews were iteratively analyzed using interpretative phenomenological methods., Results: Eleven participants were recruited and depicted their ideal rehabilitation program of care. Participants described the importance of a patient centered-approach, health care providers who were validating, reassuring and attentive, easier access to health services, a supportive and collaborative team environment, and receiving peer support. Furthermore, participants expressed that they would expect the program of care to result in their symptoms being less intense and intermittent. In consideration of the participant perspectives, the ideal rehabilitation program of care can be conceptualized by the enactive-biopsychosocial model, which provides a theoretical framework for developing and implementing the program of care., Conclusion: We obtained valuable information from individuals living with DCR regarding their preferences and expectations of a rehabilitation program of care. The participant descriptions will provide the groundwork for its development to meet patient needs and expectations. Future research to guide implementation will also be explored.

Objective: This study aimed to describe the characteristics associated with unmet rehabilitation needs in a sample of Canadians with long-term health conditions or disabilities during the first wave of the COVID-19 pandemic., Design: We used data from the Impacts of COVID-19 on Canadians Living With Long-Term Conditions and Disabilities, a national cross-sectional survey with 13,487 respondents. Unmet needs were defined as needing rehabilitation (ie, physiotherapy/massage/chiropractic, speech therapy, occupational therapy, counseling services, or support groups) but not receiving due to the pandemic. We used multivariable modified Poisson regression to examine the association between demographic, socioeconomic, and health-related characteristics and unmet rehabilitation needs., Results: More than half of the sample were 50 years and older (52.3%), female (53.8%), and 49.3% reported unmet rehabilitation needs. Those more likely to report unmet needs were females, those with lower socioeconomic status (receiving disability benefits or social assistance, job loss, increased work hours, decreased household income or earnings), and those with lower perceived general health or mental health status., Conclusions: Among Canadians with disabilities or chronic health conditions, marginalized groups are more likely to report unmet rehabilitation needs. Understanding the systemic and upstream determinants is necessary to develop strategies to minimize unmet rehabilitation needs and facilitate the delivery of equitable rehabilitation services., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2023 The Author(s).

Objectives: To estimate the one-month prevalence of problematic psychological symptoms among Canadian postsecondary students, and to compare the prevalence by student characteristics., Participants: Three samples of students from two postsecondary institutions., Methods: In a cross-sectional study conducted in 2017, we measured self-reported problems related to symptoms of depression, anxiety, and stress using questions from the functioning module of the WHO Model Disability Survey. We used modified Poisson regression modeling to compute prevalence ratios (95%CI) to compare the prevalence by student characteristics., Results: Our study included 1392 students (participation rate 35%-77%). Across samples, the one-month prevalence of moderate-extreme problems ranged from 50.8%-64.7% for anxiety, 41.2%-60.8% for stress, and 29.4%-43.6% for depression. Such problems were consistently more prevalent among females, poor-quality sleepers, students with food insecurity and those with insufficient social support., Conclusions: Significant burden of problems related to psychological symptoms exists within the postsecondary student population and varies by student characteristics.

Study Objectives: Sleep quality is important during childhood and adolescence. Given the high prevalence of pain in children/youth with cerebral palsy, we aimed to measure the association between short-term pain trajectories and sleep disturbance in these individuals., Methods: We accrued the cohort between November 2019 and October 2020 and recruited children/youth who (1) were 8-18 years old; (2) had cerebral palsy with any Gross Motor Function Classification System level; and (3) could self-report pain and sleep disturbance. We collected self-reported baseline and weekly follow-up data using electronic questionnaires completed every week for 5 weeks. Sleep disturbance at 5 weeks was the primary outcome (pediatric Patient-Reported Outcomes Measurement Information System short form, v1.0-4a). We used general linear regression to assess the association between pain intensity trajectory group and sleep disturbance controlling for confounders., Results: A total of 190 individuals were eligible; 102 were enrolled and 89 were included in our final analysis. Pain trajectory groups had estimated crude mean sleep disturbance scores at 5 weeks ranging from 56.0 (95% confidence interval, 51.8, 60.8) to 61.8 (55.7, 67.9). Compared to those with stable, no/very mild pain, those in the stable, high-pain group had the greatest sleep disturbance (adjusted β = 5.7; 95% confidence interval, 1.2, 10.2)., Conclusions: Irrespective of pain trajectory, children and youth with cerebral palsy reported sleep disturbances. Those with a stable, high pain intensity in the previous 5 weeks reported the greatest sleep disturbance. The results highlight the importance of considering pain trajectories and their impact on sleep in children with cerebral palsy., Citation: Shearer HM, Côté P, Hogg-Johnson S, Fehlings DL.

Introduction: The effectiveness of post-surgical rehabilitation following lumbar disc herniation (LDH) surgery is unclear., Research Question: To investigate the effectiveness and safety of rehabilitation interventions initiated within three months post-surgery for adults treated surgically for LDH., Material and Methods: This systematic review searched seven databases from inception to November 2023. Independent reviewers screened studies, assessed and extracted data, and rated the certainty of the evidence using the GRADE approach., Results: This systematic review retrieved 20,531 citations and included 25 randomized controlled trials. The high certainty evidence suggests that adding Pilates exercise to routine care and cognitive behavioral therapy may improve function immediately post-intervention (1 RCT), and that adding whole-body magnetic therapy to exercise, pharmacological and aquatic therapy may reduce low back pain intensity (1 RCT) immediately post-intervention. Compared to placebo, pregabalin did not reduce low back pain or leg pain intensity (1 RCT) (moderate to high certainty evidence). We found no differences between: 1) behavioral graded activity vs. physiotherapy (1 RCT); 2) exercise and education vs. neck massage or watchful waiting (1 RCT); 3) exercise, education, and in-hospital usual care vs. in-hospital usual care (1 RCT); 4) functional or staged exercise vs. usual post-surgical care including exercise (2 RCTs); and 5) supervised exercise with education vs. education (1 RCT). No studies assessed adverse events., Discussion and Conclusion: Evidence on effective and safe post-surgical rehabilitation interventions is sparse. This review identified two interventions with potential short-term benefits (Pilates exercises, whole-body magnetic therapy) but safety is unclear, and one with an iatrogenic effect (pregabalin)., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests.

Introduction: Understanding healthcare utilization by Canadians with back problems informs healthcare planning nationally., Research Question: What is the prevalence of utilization of healthcare providers (medical doctors, chiropractors, physiotherapists, nurses), and associated characteristics among Canadians with chronic back problems (2001-2016)?, Material and Methods: This population-based study used Canadian Community Health Survey data (2001-2016) restricted to respondents with chronic back problems (aged ≥12 years). We used self-reported consultation with healthcare providers (medical doctors, chiropractors, physiotherapists, nurses) from 2001-2010, and self-reported regular healthcare provider from 2015-2016. We calculated the 12-month prevalence of utilization with providers, and used modified Poisson regression to assess sociodemographic, health-related and behavioural factors associated with utilization of different providers., Results: From 2001 to 2010 and 2015/2016, respectively, prevalence of utilization of medical doctors was 87.9% (95% CI 87.6-88.2) and 86.7% (95% CI 85.9-87.5); chiropractors 24.0% (95% CI 23.6-24.4) and 14.5% (95% CI 13.8-15.3); physiotherapists 17.2% (95% CI 16.9-17.6) and 10.7% (95% CI 10.0-11.4); nurses 14.0% (95% CI 13.7-14.2) and 6.6% (95% CI 6.1-7.0). Females were more likely to see any provider than males. Persons of lower socioeconomic status were less likely to consult chiropractors or physiotherapists (2001-2016), or nurses (2001-2010). Immigrants were less likely to consult chiropractors or nurses. Persons aged >65 years were less likely to consult chiropractors or physiotherapists, and those with fair/poor general health were less likely to consult chiropractors, but more likely to consult other providers., Discussion and Conclusion: Medical doctors were most commonly consulted by Canadians with back problems, then chiropractors and physiotherapists. Characteristics of healthcare utilization varied by provider. Findings inform the need to strengthen healthcare delivery for Canadians with back problems., Competing Interests: Jessica Wong is supported by a Canadian Institutes of Health Research (CIHR) Research Excellence, Diversity and Independence Early Career Transition Award, was previously supported by a Banting Postdoctoral Fellowship from CIHR and reports research grant from the Canadian Chiropractic Research Foundation (paid to university); research grants from CIHR, Social Sciences and Humanities Research Council (SSHRC), Canadian Memorial Chiropractic College and Canadian Chiropractic Research Foundation (paid to university) and travel reimbursement for teaching and research meetings from Eurospine and Chiropractic Academy of Research Leadership outside the submitted work.

This review sought to identify, critically appraise, compare, and summarize the literature on the reliability, discriminative validity and responsiveness of the flexion relaxation ratio (FRR) in adults (≥ 18 years old) with or without spine pain (any duration), in either a clinical or research context. The review protocol was registered on Open Science Framework ( https://doi.org/10.17605/OSF.IO/27EDF ) and follows COSMIN, PRISMA, and PRESS guidelines. Six databases were searched from inception to June 1, 2022. The search string was developed by content experts and a health services librarian. Two pairs of reviewers independently completed titles/abstracts and full text screening for inclusion, data extraction, and risk of bias assessment (COSMIN RoB Toolkit). At all stages, discrepancies were resolved through consensus meetings. Data were pooled where possible with a three-level random effects meta-analyses and a modified GRADE assessment was used for the summary of findings. Following duplicate removal, 728 titles/abstracts and 219 full texts were screened with 23 included in this review. We found, with moderate certainty of evidence, that the cervical FRR has high test-retest reliability and lumbar FRR has moderate to high test-retest reliability, and with high certainty of evidence that the cervical and lumbar FRR can discriminate between healthy and clinical groups (standardized mean difference - 1.16 [95% CI - 2.00, - 0.32] and - 1.21 [- 1.84, - 0.58] respectively). There was not enough evidence to summarize findings for thoracic FRR discriminative validity or the standard error of measurement for the FRR. Several studies used FRR assuming responsiveness, but no studies were designed in a way that could confirm responsiveness. The evidence supports adequate reliability of FRR for the cervical and lumbar spine, and discriminative validity for the cervical and lumbar spine only. Improvements in study design and reporting are needed to strengthen the evidence base to determine the remaining measurement properties of this outcome., (© 2024. The Author(s).)

Objective: We aimed to describe the prevalence of unmet rehabilitation needs among a sample of Canadians living with long-term conditions or disabilities during the first wave of the COVID-19 pandemic., Design: Cross-sectional survey., Setting: Individuals residing in Canada during the first wave of the COVID-19 pandemic., Participants: Eligible participants were Canadians living with long-term conditions or disabilities, 15 years or older living in 1 of the 10 provinces or 3 territories (n=13,487)., Interventions: Not applicable., Main Outcome Measure: We defined unmet rehabilitation needs as those who reported needing rehabilitation (ie, physiotherapy/massage therapy/chiropractic, speech, or occupational therapy, counseling services, support groups) but did not receive it because of the COVID-19 pandemic. We calculated the national, age, gender, and province/territory-specific prevalence and 95% confidence interval of unmet rehabilitation needs., Results: During the first wave of the pandemic, the prevalence of unmet rehabilitation needs among Canadians with long-term conditions or disabilities was 49.3% (95% confidence interval [CI]; 48.3, 50.3]). The age-specific prevalence was higher among individuals 15-49 years old (55.6%; 95% CI [54.2, 57.1]) than those 50 years and older (46.0%; 95% CI [44.5, 47.4]). Females (53.7%; 95% CI [52.6, 54.9]) had higher unmet needs than males (44.1%; 95% CI [42.3, 45.9]). Unmet rehabilitation needs varied across provinces and territories., Conclusions: In this sample, almost 50% of Canadians living with long-term conditions or disabilities had unmet rehabilitation needs during the first wave of the COVID-19 pandemic. This suggests that a significant gap between the needs for and delivery of rehabilitation care existed during the early phase of the pandemic., (Copyright © 2023 American Congress of Rehabilitation Medicine.

Background: Chronic health conditions impact worker outcomes but are challenging to measure using administrative workers' compensation (WC) data. The Functional Comorbidity Index (FCI) was developed to predict functional outcomes in community-based adult populations, but has not been validated for WC settings. We assessed a WC-based FCI (additive index of 18 conditions) for identifying chronic conditions and predicting work outcomes., Methods: WC data were linked to a prospective survey in Ohio (N = 512) and Washington (N = 2,839). Workers were interviewed 6 weeks and 6 months after work-related injury. Observed prevalence and concordance were calculated; survey data provided the reference standard for WC data. Predictive validity and utility for control of confounding were assessed using 6-month work-related outcomes., Results: The WC-based FCI had high specificity but low sensitivity and was weakly associated with work-related outcomes. The survey-based FCI suggested more comorbidity in the Ohio sample (Ohio mean = 1.38; Washington mean = 1.14), whereas the WC-based FCI suggested more comorbidity in the Washington sample (Ohio mean = 0.10; Washington mean = 0.33). In the confounding assessment, adding the survey-based FCI to the base model moved the state effect estimates slightly toward null (<1% change). However, substituting the WC-based FCI moved the estimate away from null (8.95% change)., Conclusions: The WC-based FCI may be useful for identifying specific subsets of workers with chronic conditions, but less useful for chronic condition prevalence. Using the WC-based FCI cross-state appeared to introduce substantial confounding. We strongly advise caution-including state-specific analyses with a reliable reference standard-before using a WC-based FCI in studies involving multiple states., (© 2023 Wiley Periodicals LLC.)

Abstract: Degenerative cervical radiculopathy (DCR) can lead to severe pain, paraesthesia, and/or motor weakness, resulting in significant morbidity, disability, and reduced quality of life. Typically, individuals suffer from prolonged symptoms, with time to complete recovery spanning months to years. Little is known about the impact DCR has on peoples' lives. Therefore, this study aimed to explore the everyday experiences of individuals living with DCR. A qualitative study was conducted through an interpretivist lens exploring the experiences of participants. Participants were purposefully recruited and interviewed with 2 research team members. Transcripts were independently analyzed by 2 reviewers and coding was finalized by consensus. Analysis was performed using an interpretative phenomenological approach, with emergent themes mapped onto the 5 domains of the International Classification of Functioning, Disability and Health framework. Eleven participants were interviewed between December 2021 and April 2022. Three themes emerged: the biopsychosocial impact of DCR, role of the health care provider, and uncertainty surrounding DCR. Pain and paraesthesia were the most common symptoms experienced by participants, leading to significant psychological distress and impact to daily activities, most notably driving, housecleaning, sleep, and ability to work. Participants described the uncertainty they experienced as a result of the unpredictable nature of DCR and the important role that health care providers play in their journey with DCR. Health care providers were seen acting as either a facilitator or a barrier to their recovery. The findings from this study can be used by clinicians providing patient-centered care to better understand the experiences of people with DCR., (Copyright © 2023 The Author(s).

Introduction: Individuals with participation and activity limitations face important healthcare challenges., Objectives: We investigated healthcare utilization and characteristics of Canadians living with participation and activity limitations between 2001 and 2010., Methods: We pooled data from 5 cycles of the Canadian Community Health Survey (2001-2010 CCHS). The multistage stratified cluster-sampling method used covered approximately 98% of Canadians, aged 12 years and older residing in private dwellings. We described sociodemographic, behavioral, and health-related characteristics of participants with participation and activity limitations and reported their annual utilization (prevalence; 95% CI) of 7 healthcare providers. Multivariable modified Poisson regression identified individual characteristics associated with healthcare utilization and examined the trends over time., Results: Annually, 8.1 million Canadians aged 12 years and older (29.8%) reported participation and activity limitations. Most common health conditions were back problems (37%) and arthritis (34%). Predominant healthcare providers were medical doctors (88.8%; 95% CI = 88.6-89.0), nurses (16.3%; 95% CI = 16.1-16.6), physiotherapists (15.0%; 95% CI = 14.7-15.2), and chiropractors (14.4%; 95% CI = 14.2-14.7). Overall, males, older adults, immigrants, those with lower education, lower income, recent employment, and better general health were less likely to consult providers. Over time, utilization of most non-medical providers increased., Conclusion: Participation and activity limitations are prevalent in Canada, and most consulted medical doctors. Disadvantaged groups reported lower utilization of most providers, emphasizing access challenges and the need for equitable and integrated healthcare policies. Improving access to rehabilitation services and their inclusion within universal healthcare coverage should be a priority., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The World Health Organization Disability Assessment Schedule 2.0 12-item survey (WHODAS-12) is a questionnaire developed by the WHO to measure functioning across health conditions, cultures, and settings. WHODAS-12 consists of a subset of the 36 items of WHODAS-2.0 36-item questionnaire. Little is known about the minimal important difference (MID) of WHODAS-12 in persons with chronic low back pain (LBP), which would be useful to determine whether rehabilitation improves functioning to an extent that is meaningful for people experiencing the condition. Our objective was to estimate an anchor-based MID for WHODAS-12 questionnaire in persons with chronic LBP., Methods: We analyzed data from two cohort studies (identified in our previous systematic review) conducted in Europe that measured functioning using the WHODAS-36 in adults with chronic LBP. Eligible participants were adults with chronic LBP with scores on another measure as an anchor to indicate participants with small but important changes in functioning over time [Short-form-36 Physical Functioning (SF36-PF) or Oswestry Disability Index (ODI)] at baseline and follow-up (study 1: 3-months post-treatment; study 2: 1-month post-discharge from hospital). WHODAS-12 scores were constructed as sums of the 12 items (scored 0-4), with possible scores ranging from 0 to 48. We calculated the mean WHODAS-12 score in participants who achieved a small but meaningful improvement on SF36-PF or ODI at follow-up. A meaningful improvement was an MID of 4-16 on ODI or 5-16 on SF36-PF., Results: Of 70 eligible participants in study 1 (mean age = 54.1 years, SD = 14.7; 69% female), 18 achieved a small meaningful improvement based on SF-36 PF. Corresponding mean WHODAS-12 change score was - 3.22/48 (95% CI -4.79 to -1.64). Of 89 eligible participants in study 2 (mean age = 65.5 years, SD = 11.5; 61% female), 50 achieved a small meaningful improvement based on ODI. Corresponding mean WHODAS-12 change score was - 5.99/48 (95% CI - 7.20 to -4.79)., Conclusions: Using an anchor-based approach, the MID of WHODAS-12 is estimated at -3.22 (95% CI -4.79 to -1.64) or -5.99 (95% CI - 7.20 to -4.79) in adults with chronic LBP. These MID values inform the utility of WHODAS-12 in measuring functioning to determine whether rehabilitation or other health services achieve a minimal difference that is meaningful to patients with chronic LBP., (© 2023.

Objective: To identify, appraise and synthesize the evidence of autonomic nervous system (ANS) dysfunction following sport-related concussion in pediatric populations., Methods: A literature search was conducted using MEDLINE (Ovid), SportDiscus (EBSCO), CINAHL (EBSCO), EMBASE (Ovid) and PsycINFO (Ovid). Studies were selected and appraised using the Joanna Briggs Institute (JBI) critical appraisal tools. Data was extracted from the included studies and qualitatively synthesized., Results: Eleven studies were included in the synthesis. There was variability in the methods used to measure ANS function between studies, and sample populations and time to assessment following concussion varied considerably. There was also variability in the direction of change of ANS function between some studies., Conclusion: This systematic review identifies that concussion is associated with dysregulation of ANS function in pediatric athletes. We identified some weaknesses in the extant literature which may be due to existing logistical and financial barriers to implementing valid ANS measurements in clinical and sports settings., Competing Interests: The authors have no disclaimers, competing interests, or sources of support or funding to report in the preparation of this manuscript., (© JCCA 2023.)

Driving posture can lead to musculoskeletal pain. Most work focuses on the lower back; therefore, we know little about automobile seat design and neck posture. This study evaluated an automobile driver seat that individualized upper back support to improve head and neck posture. Specifically, we examined the system's impact on anterior head translation with secondary outcomes of spine posture and perceptions of comfort/well-being compared with a control. Forty participants were block randomized to experience either the activated or deactivated version of the same seating system first. Participants completed two 30-minute simulated driving trials, separated by washout, with continuous measures of anterior head translation, spine posture, and pelvis orientation. Perceptions of comfort/well-being were assessed by survey and open-ended questions immediately following each condition. Small, but statistically significant decreases in anterior head translation and posterior pelvic tilt occurred with the activated seat system. Participants reported lower satisfaction with the activated seat system. Order of the 2 seat conditions affected differences in pelvis orientation and participant perceptions of comfort/well-being. An anthropometric-based seat system targeting upper back support can significantly affect head and pelvic posture but not satisfaction during simulated driving. Future work should examine long-term impacts of these posture changes on health outcomes.

Objective: This study investigated the moderating role of baseline depressive symptoms on the association between baseline pain severity and time to recovery in individuals with acute grade I-II whiplash-associated disorders., Design: This is a secondary analysis of a randomized controlled trial investigating the effectiveness of a government-regulated rehabilitation guideline for the management of grade I-II whiplash-associated disorders. Participants who completed baseline questionnaires for neck pain intensity and depressive symptoms and follow-up questionnaire on self-reported recovery were included in the analysis. Cox proportional hazards models were built, and hazard rate ratios were reported to describe the association between baseline neck pain intensity and time to self-reported recovery and to assess the effect modification of baseline depressive symptoms., Results: Three hundred three participants provided data for this study. Despite baseline level of depressive symptoms and neck pain intensity being independently associated with delayed recovery, the association between baseline neck pain intensity and time to recovery was not stronger for individuals with significant postcollision depressive symptoms (hazard rate ratio = 0.91; 95% confidence interval = 0.79-1.04) than for those without depressive symptoms (hazard rate ratio = 0.92; 95% confidence interval = 0.83-1.02)., Conclusions: Baseline depressive symptoms are not an effect modifier of the association between baseline neck pain intensity and time to self-reported recovery in acute whiplash-associated disorders., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2023 Wolters Kluwer Health, Inc.

Study Design: Systematic review., Objective: The aim of this study was to evaluate the inclusion and exclusion criteria for participants in randomized control trials (RCTs) assessing conservative management for cervical radiculopathy (CR), to determine if any consensus exists within the literature., Summary of Background Data: A 2012 systematic review identified a lack of uniformity for the eligibility criteria of participants in RCTs evaluating conservative interventions for CR. Since then, a large number of RCTs have been published, signaling the need for an updated evaluation of this topic., Materials and Methods: We electronically searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022, to identify RCTs assessing conservative management of CR. Information extracted was analyzed to determine the level of homogeneity and/or heterogeneity of the inclusion and exclusion criteria across studies., Results: Seventy-six RCTs met our inclusion criteria with 68 distinct trials identified. The inclusion of arm pain with or without another symptom ( i.e. numbness, paresthesia, or weakness) was required in 69.12% of trials, 50% of trials required participants to exhibit neck symptoms, and 73.53% of studies required some form of clinical examination findings, but inconsistencies existed for the number and type of tests used. Furthermore, 41.18% of trials included imaging, with 33.82% of trials requiring magnetic resonance imaging findings. The most common exclusion criteria included were the presence of red flags and cervical myelopathy in 66.18% and 58.82% of trials, respectively., Conclusions: Overall, there is still a lack of uniformity for the inclusion/exclusion criteria of trials assessing the conservative management of CR, with some improvements noted compared with the 2012 review. Based on the current literature assessing the diagnostic utility of clinical symptoms and confirmatory tests, we proposed inclusion criteria for trials assessing conservative interventions. Future research should aim to develop standardized classification criteria to improve consistency among studies., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: The purpose of this systematic review was to assess the effectiveness and safety of conservative interventions compared with other interventions, placebo/sham interventions, or no intervention on disability, pain, function, quality of life, and psychological impact in adults with cervical radiculopathy (CR)., Methods: We searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022 to identify studies that were randomized controlled trials, had at least one conservative treatment arm, and diagnosed participants with CR through confirmatory clinical examination and/or diagnostic tests. Studies were appraised using the Cochrane Risk of Bias 2 tool and the quality of the evidence was rated using the Grades of Recommendations, Assessment, Development, and Evaluation approach., Results: Of the 2561 records identified, 59 trials met our inclusion criteria (n = 4108 participants). Due to clinical and statistical heterogeneity, the findings were synthesized narratively. There is very-low certainty evidence supporting the use of acupuncture, prednisolone, cervical manipulation, and low-level laser therapy for pain and disability in the immediate to short-term, and thoracic manipulation and low-level laser therapy for improvements in cervical range of motion in the immediate term. There is low to very-low certainty evidence for multimodal interventions, providing inconclusive evidence for pain, disability, and range of motion. There is inconclusive evidence for pain reduction after conservative management compared with surgery, rated as very-low certainty., Discussion: There is a lack of high-quality evidence, limiting our ability to make any meaningful conclusions. As the number of people with CR is expected to increase, there is an urgent need for future research to help address these gaps., Competing Interests: C.C. receives funding to develop, adopt or adapt guidelines related to musculoskeletal health and knowledge translation activities and research.

Objective: To determine the measurement properties and minimal important change (MIC) of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) short (12 questions) and full (36 questions) versions in persons with nonspecific low back pain (LBP)., Data Sources: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, APA PsycInfo, and Cochrane Central Register of Controlled Trials (inception to May 2021)., Study Selection: Eligible studies assessed measurement properties or MIC of WHODAS 2.0 in persons with LBP., Data Extraction: Paired reviewers screened articles, extracted data, and assessed risk of bias using Consensus-Based Standards for Selection of Health Measurement Instruments (COSMIN) and COSMIN-Outcome Measures in Rheumatology checklists., Data Synthesis: We descriptively synthesized results stratified by measurement property and LBP duration (subacute: 6 weeks to 3 months; chronic: ≥3 months)., Results: We screened 297 citations and included 14 studies (reported in 15 articles). Methodological quality of studies was very good for internal consistency and varied between very good and doubtful for construct validity, doubtful for responsiveness, and adequate for all other properties assessed. Evidence suggests that WHODAS 2.0 full version has adequate content validity (2 studies); WHODAS 2.0 short and full versions have adequate structural validity (3 studies), but construct validity is indeterminate (9 studies). WHODAS 2.0 short and full versions have adequate internal consistency (10 studies), and the full version has adequate test-retest and interrater reliability (3 studies) in persons with LBP. Minimal detectable change (MDC) was 10.45-13.99 of 100 for the full version and 8.6 of 48 for the short version in persons with LBP (4 studies). WHODAS 2.0 full version has no floor or ceiling effects, but the short version has potential floor effects in persons with chronic LBP (3 studies). One study estimated MIC for the full version as 4.87 of 100 or 9.74 of 100 (corresponding to 1- and 2-point change on 0- to 10-cm visual analog scale for pain, respectively), and 1 study estimated 3.09-4.68 of 48 for the short version., Conclusions: In persons with LBP, WHODAS 2.0 full version has adequate content validity, structural validity, internal consistency, and reliability. WHODAS 2.0 short version has adequate structural validity and internal consistency. Construct validity of the short and full versions is indeterminate. Since MDC is estimated to be larger than MIC, users may consider both MIC and MDC thresholds to measure change in functioning for LBP., (Copyright © 2022 The Authors. Published by Elsevier Inc.

Aim: To describe the clinical course of pain intensity in individuals with cerebral palsy (CP) resulting from usual care or specific interventions., Method: We conducted an exploratory prognostic systematic review searching electronic databases from inception to 31st December 2021. Evidence from low and moderate risk-of-bias studies was synthesized., Results: We retrieved 2275 citations; 18 studies met the inclusion criteria and 10 were synthesized. The course of pain intensity in children with CP receiving usual care was stable over 15 weeks (χ 2 [2]  = 1.8, p = 0.5). Children who received continuous intrathecal baclofen (CITB) reported significant pain intensity reduction (visual analogue scale [VAS] = -4.2 out of 10, 95% confidence interval [CI] = -6.3 to -2.1]) 6 months postinsertion but similar children receiving usual care had no significant change over 6 months (VAS = 1.3 out of 10, 95% CI = -1.3 to 3.6). Children receiving botulinum neurotoxin A (BoNT-A) injections had significant decreases in pain after 1 month (numeric rating scale = -6.5, 95% CI = -8.0 to -5.0). Adults with chronic pain receiving usual care reported stable pain intensity over time; pain intensity improved in ambulatory adults exercising and those treated surgically for cervical myelopathy., Interpretation: The course of pain intensity in individuals with CP is unclear. Evidence suggests that children and adults receiving usual care had stable pain intensity over the short or long term. Interventions (CITB and BoNT-A in children and exercise and surgical treatment for cervical myelopathy in adults) had pain intensity reduction. Larger study samples are needed to confirm these results., What This Paper Adds: Pain intensity was stable in children with cerebral palsy (CP) receiving usual care. Adults with CP and chronic pain receiving usual care had stable, persistent pain intensity. Children receiving continuous intrathecal baclofen via pump and botulinum neurotoxin A reported significantly lower pain intensities. Adults with chronic pain and dyskinetic CP and cervical myelopathy reported significantly lower pain intensity with exercise or cervical decompression. Limited high-quality evidence exists describing non-procedural pain changes in individuals with CP., (© 2022 Mac Keith Press.)

Background: Shoulder problems are common in swimmers. Previous research has focused on elite swimmers. Our research questions were: 1) what is the prevalence of shoulder problems among Ontario age group swimmers and 2) how does prevalence relate to age, sex and years of experience?, Methods: A cross sectional survey was administered to youth swimmers from two Ontario clubs. Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC) was used to assess four-week prevalence of shoulder problems. Prevalence (%) with 95% confidence intervals (95% CI) was constructed and prevalence across age, sex and years of experience was investigated using cross-tabulations and chi-square tests., Results: There were 83 surveys completed (response rate 50%). The 4-week prevalence of shoulder pain was 35% (95% CI 25%, 45%). Shoulder problems were not significantly related to age, sex or years of experience., Conclusion: These results can inform future studies on injury prevention and risk mitigation strategies in swimmers., Competing Interests: The authors have no disclaimers, competing interests, or sources of support or funding to report in the preparation of this manuscript., (© JCCA 2022.)

Knowledge of the pre-rehabilitation generic status of functioning in individuals with low back pain is necessary to understand the clinical utility of rehabilitation care. We conducted a scoping review to describe the pre-rehabilitation functioning status of persons with nonspecific low back pain using the World Health Organization Disability Assessment Schedule (WHODAS)-36 or WHODAS-12. We searched multiple databases from 2010 to 2021 for studies reporting pre-rehabilitation scores using WHODAS in persons with low back pain. Reviewers independently screened articles and extracted data, and we descriptively summarized results by the duration of low back pain (acute/subacute <3 months; chronic ≥3 months), and the WHODAS version. Of 1770 citations screened, eight citations were relevant. Five studies were conducted in Europe, two in America, and one in the African Region (mostly high-income countries). In persons with acute low back pain, the mean WHODAS-36 pre-rehabilitation summary score (complex scoring) was 22.8/100 (SD = 15.4) (one study). In persons with chronic low back pain, the mean WHODAS-36 summary score (complex scoring) ranged from 22.8/100 (SD = 5.7) to 41.5/100 (SD = 13.8) (two studies). For WHODAS-12 in persons with chronic low back pain, the mean summary score was 11.4/48 (SD = 8.7) or 14.4/48 (SD = 9.4) using simple scoring (two studies), and 25.8/100 (SD = 2.2) using complex scoring (one study). No floor or ceiling effects were observed in WHODAS-36 summary scores for chronic low back pain. Our scoping review comprehensively summarizes available studies reporting pre-rehabilitation levels of functioning using WHODAS in persons with low back pain. Persons with low back pain seeking rehabilitation have moderate limitations in functioning, and limitations level tends to be worse with chronic low back pain., (Copyright © 2022 The Author(s).

Aim: To identify 5-week pain intensity trajectories and their association with physical and psychological well-being in children/young people with cerebral palsy (CP)., Method: A cohort study was conducted with 101 Canadian children/young people with CP, of whom 49 were female, with an overall mean age of 12 years 11 months (SD 3 years 1 month), range of 8 to 18 years, and classified in any Gross Motor Function Classification System level. Self-reported pain intensity (Faces Pain Scale - Revised) was collected weekly for 5 weeks and physical and psychological well-being (KIDSCREEN-27) at baseline and 5 weeks. Statistical analyses included latent class growth and general linear models., Results: All Gross Motor Function Classification System levels were represented (I = 40.6%; II = 15.8%; III = 20.8%; IV = 13.9%; V = 8.9%). Five pain intensity trajectories were identified. Three trajectories had very low (35.4%), low (32.4%), or high (4.9%) mean stable pain. Two trajectories had moderate changing pain (16.8%) and high pain decreasing to moderate levels (10.5%) respectively. Trajectory participants with stable high pain had the lowest physical well-being (adjusted β = -10.01; 95% confidence interval [CI] = -19.37 to -0.66). Those in the three trajectories with the highest mean baseline pain intensity (>3 out of 10) had the lowest psychological well-being (adjusted β = -8.27, 95% CI = -14.84 to -1.70; β = -6.74, 95% CI = -12.43 to -1.05; β = -5.82, 95% CI = -15.34 to 3.71)., Interpretation: Almost one-third of participants had moderate-to-high pain intensity trajectories. Membership in the higher pain intensity trajectories was associated with lower physical and psychological well-being., What This Paper Adds: Five distinct 5-week pain intensity trajectories were identified in children/young people with cerebral palsy. Thirty-two per cent of participants had moderate-to-high pain intensity trajectories. Participants in the trajectories with higher pain intensity reported lower physical and psychological well-being., (© 2022 The Authors.

Background: Diagnostic imaging is useful for assessing low back pain (LBP) when a clinician suspects a specific underlying pathology. Evidence-based imaging guidelines assist clinicians in appropriately determining the need for imaging when assessing LBP. A previous study reported high adherence to three clinical guidelines, with utilization rate of 12.3% in imaging of LBP patients attending a chiropractic teaching clinic. A new imaging guideline for spinal disorders has been published and used in teaching. Thus, the aims of our study were to assess the adherence to the new guideline and X-ray utilization in new episodes of LBP., Methods: We conducted a historical clinical cohort study using patient electronic health record audits at seven teaching clinics over a period of 20 months. Records of patients who were at least 18 years of age, presented with a new onset of LBP, and consented to data collection were included. Abstracted data included patient demographics, the number and type of red flags, and the decision to image. Rate of guideline adherence (proportion of those not recommended for imaging, given no red flags) and rate of image utilization were descriptively analyzed., Results: We included 498 patients in this study. At least 81% of included patients had one or more red flags reported. The most commonly reported individual red flag was age ≥ 50 (43.8%) followed by pain at rest (15.7%). In those referred for imaging, age ≥ 50 (93.3%) was the most frequently reported red flag. No red flag(s) were identified in 93 patient records, and none were referred for imaging of their LBP, yielding an adherence rate of 100% (95% CI 96, 100%). A total of 17 of 498 patients were recommended for imaging for their low back pain, resulting in an imaging utilization rate of 3.4% (95% CI 1.8, 5.0%)., Conclusion: The imaging utilization rate was 3.4%, lower than 12.3% previously reported at a chiropractic teaching clinic. None without red flags were referred for imaging, yielding a 100%, adherence rate to current LBP imaging guidelines. Future research should consider currency of guideline, accuracy of red flags and factors influencing clinicians' decision, when assessing imaging adherence rates., (© 2022. The Author(s).)

Context: Sarcopenia is a prevalent syndrome that has seen increased awareness in the last twenty years., Objective: To systematically assess and evaluate the utility of bioelectrical impedance analysis (BIA) in the diagnosis of sarcopenia in adults over the age of 60., Methods: An electronic search strategy of databases was conducted, including Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, and SportDiscus. Included articles were evaluated using The Quality Appraisal for Reliability Studies (QAREL) checklist., Results: Seven articles (1336 participants) met the inclusion criteria of evaluating the diagnostic ability of BIA. Results indicate that that there is a high degree of heterogeneity in how BIA is used to diagnose sarcopenia. While BIA is an affordable and easy to use measurement tool, it does not consistently demonstrate high levels of diagnostic sensitivity., Conclusion: The current evidence does not consistently support the utility of BIA as an accurate diagnostic tool for sarcopenia in adults over 60. If utilizing BIA, clinicians should select a validated BIA equation for their patient's demographics. Clinicians should also consider the use of functional tests and validated screening questionnaires.

Background: Older workers are increasingly represented in the U.S. workforce, but frequently work part-timeor intermittently, hindering accurate injury rate estimates. To reduce the impact of reporting barriers on rate comparisons, we focused on reinjury (both injury recurrence and new injury) among workers with a workers' compensation claim, assessing: (1) reinjury risk for workers age 65+ versus <65; (2) importance of work-time at-risk measurement for rate estimates and comparisons; and (3) age distribution of potential risk factors., Methods: Washington State workers' compensation claims for a retrospective cohort of workers with work-related permanent impairments were linked to state wage files. Reinjury rates were calculated for the cohort (N = 11,184) and a survey sample (N = 582), using both calendar time and full-time equivalent (FTE)-adjusted time. Risk differentials were assessed using rate ratios and adjusted survival models., Results: The rate ratio for workers age 65+ (vs. <65) was 0.45 (p < 0.001) using calendar time, but 0.70 (p = 0.07) using FTE-adjusted time. Survey-based rates were 35.7 per 100 worker-years for workers age 65+, versus 14.8 for <65. Workers age 65+ (vs. <65) were more likely to work <100% FTE, but were similar regarding job strain, their ability to handle physical job demands, and their comfort reporting unsafe conditions or injuries., Conclusions: Accounting for work-time at risk substantially improves age-based reinjury comparisons. Although the marked elevation in self-reported reinjury risk for older workers might be a small-sample artifact (n = 34), workers age 65+ are likely at higher risk than previously appreciated. Ongoing workforce trends demand increased attention to injury surveillance and prevention for older workers., (© 2022 Wiley Periodicals LLC.)

Background: Degenerative cervical radiculopathy (DCR) is a common condition which, due to the aging global population, is expected to worsen over time. For the majority of patients with DCR, surgical intervention is not required as nonoperative management is sufficient for symptom improvement. However, there are significant gaps within the literature as the majority of past systematic reviews assessing conservative interventions are outdated, or omit relevant studies due to strict inclusion/exclusion criteria. Therefore, an updated understanding of the effectiveness of noninvasive nonoperative management for DCR is required., Methods: We will search MEDLINE, CENTRAL, Embase, PsycINFO, and CINAHL from inception, as well as hand-search reference lists of included studies and previous systematic reviews, to identify peer-reviewed randomized controlled trials on this topic., Discussion: The results of this review will provide an understanding of the effectiveness of various nonoperative interventions. The quality of evidence will also be assessed using the GRADE approach., Systematic Review Registration: PROSPERO CRD42021249699., Competing Interests: The authors have no disclaimers, competing interests, or sources of support or funding to report in the preparation of this manuscript., (© JCCA 2022.)

Objective: We set out to identify factors associated with recording of exercise minutes per week in electronic patient files at chiropractic teaching clinics to better understand whether this important health determinant - exercise vital sign (EVS) - is captured or not., Methods: Patient files (4018) from 23 clinicians eligible for inclusion underwent multilevel logistic regression modeling to explore the association between a recorded EVS and the following: patients' age, sex, comorbidities and interns nested within clinicians., Results: EVS discussion was documented in 81.2% of patient files, whereas 44.9% had exercise minutes recorded numerically. Clinicians and interns explained 1.7% and 25.5% of the variance in the EVS outcome., Conclusion: To enhance EVS recording, clinic directors and clinicians should better educate the interns on the importance of exercise is medicine and appropriate record keeping, as they explained the largest portion of variability in recording exercise in minutes per week., Competing Interests: The authors have no disclaimers or competing interests to report in the preparation of this manuscript. This work was funded internally by the Canadian Memorial Chiropractic College., (© JCCA 2022.)

Background: While pain is often the focus of clinical interventions, other clinical outcomes (e.g., discomfort, stiffness) might also contribute to patients' functionality and well-being. Although researchers and clinicians may view discomfort, pain and stiffness as different constructs, it remains unclear how patients perceive and differentiate between these constructs. Therefore, the purpose of this study was to explore patients' perceptions of pain, discomfort, and stiffness., Methods: Chiropractic patients were invited to complete an online cross-sectional survey and describe what 'discomfort', 'pain' and 'stiffness' meant to them using their own words. Lexical and inductive qualitative content analyses were conducted independently and then triangulated., Results: Fifty-three chiropractic patients (47.2% female, mean age: 39.1 ± 15.1 years) responded. The most common combinations of words to describe discomfort were "can be ignored" and "less severe than". "Cannot be ignored" and "sharp shooting" were used to describe pain. "Limited range of motion" was used to describe stiffness. Qualitatively, five themes were developed: impact, character, feeling, intensity and temporality. Stiffness was described as limited movement/mobility. Although discomfort and stiffness impacted patients' activities, patients remained functional; pain was described as stopping/limiting activities. Discomfort was described as dull and tingling, pain as sharp and shooting, and stiffness as tight and restricted. Patients felt displeased and annoyed when experiencing discomfort and stiffness but hurt and in danger of harm when experiencing pain. Discomfort and stiffness were described as less intense than pain, with shorter/intermittent duration; however, all constructs could be experienced constantly., Conclusion: Patients perceived discomfort, pain and stiffness as different, yet overlapping constructs. This preliminary work advances our knowledge of how patients conceptualize these constructs, contributing to better understanding of what patients mean when reporting these experiences, potentially improving the clinician-patient communication., (© 2022.
