Effectiveness of postsurgical rehabilitation following lumbar disc herniation surgery: A systematic review

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).

The Vehicle Seating Intervention Trial: Cross-Over Randomized Controlled Trial to Evaluate the Impact of 2 Car Seat Configurations on Spinal Posture

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.

Information is power: a qualitative study exploring the lived experiences of patients with degenerative cervical radiculopathy

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.

Prevalence of Unmet Rehabilitation Needs Among Canadians Living With Long-term Conditions or Disabilities During the First Wave of the COVID-19 Pandemic

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.

Care at a distance: Understanding lived experiences of people with MSK disorders receiving non-pharmacological interventions delivered through synchronous telehealth: A systematic rapid review

Background

Little is known about lived experience of synchronous telehealth in patients with musculoskeletal (MSK) disorders.

Objective

We conducted a rapid systematic review to answer: (1) what are the lived experiences and/or perspectives of people with MSK disorders receiving non-pharmacological interventions delivered through synchronous telehealth; and (2) what clinical implications can be inferred from qualitative studies focusing on lived experiences for how telehealth is delivered in the management of MSK disorders?

Data sources

A comprehensive search of MEDLINE, CINAHL, PsycINFO, ProQuest, and Google Scholar from June 2010 to July 2023. Eligible qualitative and mixed methods studies capturing lived experiences of adults with MSK disorders receiving non-pharmacological interventions via synchronous telehealth were included.

Study methods

Systematic rapid review conducted according to WHO guidelines. Titles and abstracts screened by reviewers independently, eligible studies critically appraised, and data was extracted. Themes summarized using the Consolidated Framework for Implementation Research (CFIR). GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) used to assess confidence in synthesis findings.

Results

We identified 9782 references, screened 8029, and critically appraised 22, and included 17 studies. There is evidence to suggest that the experience of telehealth prior to and during the pandemic was shaped by (1) patient perception of telehealth, (2) existing relationships with practitioners, (3) availability and accessibility of telehealth technologies, and (4) perceptions about the importance of the role of the physical exam in assessing and treating MSK disorders.

Conclusion

The five identified implications could be used to inform future research, policy, and strategy development.

Characteristics of Canadians living with long-term health conditions or disabilities who had unmet rehabilitation needs during the first wave of the COVID-19 pandemic: A cross-sectional study

OBJECTIVE

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

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 (i.e., physiotherapy/massage/chiropractic, speech therapy, occupational therapy, counselling 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 (52.3%), female (53.8%), and 49.3% reported unmet rehabilitation needs. Those more likely to report unmet needs were females, those with lower socio-economic 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.

Identifying sports chiropractic global research priorities: an international Delphi study of sports chiropractors

Objectives

Developing a research agenda is one method to facilitate broad research planning and prioritise research within a discipline. Despite profession-specific agendas, none have specifically addressed the research needs of the specialty of sports chiropractic. This study determined consensus on research priorities to inform a global sports chiropractic research agenda.

Methods

A Delphi consensus methodology was used to integrate expert opinions. Clinicians, academics and leaders from the international sports chiropractic specialty were recruited using purposive sampling to participate in (1) a Delphi panel involving three voting rounds to determine consensus on research priorities and (2) a priority importance ranking of the items that reached consensus.

Results

We identified and contacted 141 participants, with response rates for rounds 1, 2 and 3, of 44%, 31% and 34%, respectively. From the original 149 research priorities, 66 reached consensus in round 1, 63 in round 2 and 45 items in round 3. Research priorities reaching consensus were collapsed by removing redundancies, and priority ranking identified 20 research priorities, 11 related to collaboration and 6 to research themes.

Conclusions

The top-ranked items for research priorities, research themes and collaborations included the effects of interventions on performance, recovery and return to play; clinical research in sport; and collaborations with researchers in chiropractic educational institutions, respectively.

Implications

The prioritisation of research items can be evaluated by key stakeholders (including athletes) and implemented to develop the first international research agenda for sports chiropractic.

Improving Rehabilitation Research to Optimize Care and Outcomes for People with Chronic Primary Low Back Pain: Methodological and Reporting Recommendations from a WHO Systematic Review Series

Chronic primary low back pain (CPLBP) is a prevalent and disabling condition that often requires rehabilitation interventions to improve function and alleviate pain. This paper aims to advance future research, including systematic reviews and randomized controlled trials (RCTs), on CPLBP management. We provide methodological and reporting recommendations derived from our conducted systematic reviews, offering practical guidance for conducting robust research on the effectiveness of rehabilitation interventions for CPLBP. Our systematic reviews contributed to the development of a WHO clinical guideline for CPLBP. Based on our experience, we have identified methodological issues and recommendations, which are compiled in a comprehensive table and discussed systematically within established frameworks for reporting and critically appraising RCTs. In conclusion, embracing the complexity of CPLBP involves recognizing its multifactorial nature and diverse contexts and planning for varying treatment responses. By embracing this complexity and emphasizing methodological rigor, research in the field can be improved, potentially leading to better care and outcomes for individuals with CPLBP.

Systematic Review Procedures for the World Health Organization (WHO) Evidence Syntheses on Benefits and Harms of Structured and Standardized Education/Advice, Structured Exercise Programs, Transcutaneous Electrical Nerve Stimulation (TENS), and Needling Therapies for the Management of Chronic Low Back Pain in Adults

As commissioned by the WHO, we updated and expanded the scope of four systematic reviews to inform its (in development) clinical practice guideline for the management of CPLBP in adults, including older adults. Methodological details and results of each review are described in the respective articles in this series. In the last article of this series, we discuss methodological considerations, clinical implications and recommendations for future research.

Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Transcutaneous Electrical Nerve Stimulation (TENS) for Chronic Primary Low Back Pain in Adults

PURPOSE

To evaluate benefits and harms of transcutaneous electrical nerve stimulation (TENS) for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline.

METHODS

We searched for randomized controlled trials (RCTs) from various electronic databases from July 1, 2007 to March 9, 2022. Eligible RCTs targeted TENS compared to placebo/sham, usual care, no intervention, or interventions with isolated TENS effects (i.e., combined TENS with treatment B versus treatment B alone) in adults with CPLBP. We extracted outcomes requested by the WHO Guideline Development Group, appraised the risk of bias, conducted meta-analyses where appropriate, and graded the certainty of evidence using GRADE.

RESULTS

Seventeen RCTs (adults, n = 1027; adults ≥ 60 years, n = 28) out of 2010 records and 89 full text RCTs screened were included. The evidence suggested that TENS resulted in a marginal reduction in pain compared to sham (9 RCTs) in the immediate term (2 weeks) (mean difference (MD) = -0.90, 95% confidence interval  -1.54 to -0.26), and a reduction in pain catastrophizing in the short term (3 months) with TENS versus no intervention or interventions with TENS specific effects (1 RCT) (MD = -11.20, 95% CI -17.88 to -3.52). For other outcomes, little or no difference was found between TENS and the comparison interventions. The certainty of the evidence for all outcomes was very low.

CONCLUSIONS

Based on very low certainty evidence, TENS resulted in brief and marginal reductions in pain (not deemed clinically important) and a short-term reduction in pain catastrophizing in adults with CPLBP, while little to no differences were found for other outcomes.

Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Structured and Standardized Education or Advice for Chronic Primary low back pain in Adults

PURPOSE

Evaluate benefits and harms of education/advice for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline.

METHODS

Electronic databases were searched for randomized controlled trials (RCTs) assessing education/advice compared with placebo/sham, usual care, or no intervention (including comparison interventions where the attributable effect of education/advice could be isolated). We conducted meta-analyses and graded the certainty of evidence.

RESULTS

We screened 2514 citations and 86 full text RCTs and included 15 RCTs. Most outcomes were assessed 3 to 6 months post-intervention. Compared with no intervention, education/advice improved pain (10 RCTs, MD = -1.1, 95% CI -1.63 to -0.56), function (10 RCTs, SMD = -0.51, 95% CI -0.89 to -0.12), physical health-related quality of life (HRQoL) (2 RCTs, MD = 24.27, 95% CI 12.93 to 35.61), fear avoidance (5 RCTs, SMD = -1.4, 95% CI -2.51 to -0.29), depression (1 RCT; MD = 2.10, 95% CI 1.05 to 3.15), and self-efficacy (1 RCT; MD = 4.4, 95% CI 2.77 to 6.03). Education/advice conferred less benefit than sham Kinesio taping for improving fear avoidance regarding physical activity (1 RCT, MD = 5.41, 95% CI 0.28 to 10.54). Compared with usual care, education/advice improved pain (1 RCT, MD = -2.10, 95% CI -3.13 to -1.07) and function (1 RCT, MD = -7.80, 95% CI -14.28 to -1.32). There was little or no difference between education/advice and comparisons for other outcomes. For all outcomes, the certainty of evidence was very low.

CONCLUSION

Education/advice in adults with CPLBP was associated with improvements in pain, function, HRQoL, and psychological outcomes, but with very low certainty.

Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Structured Exercise Programs for Chronic Primary Low Back Pain in Adults

PURPOSE

Evaluate benefits and harms of structured exercise programs for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline.

METHODS

We searched for randomized controlled trials (RCTs) in electronic databases (inception to 17 May 2022). Eligible RCTs targeted structured exercise programs compared to placebo/sham, usual care, or no intervention (including comparison interventions where the attributable effect of exercise could be isolated). We extracted outcomes, appraised risk of bias, conducted meta-analyses where appropriate, and assessed certainty of evidence using GRADE.

RESULTS

We screened 2503 records (after initial screening through Cochrane RCT Classifier and Cochrane Crowd) and 398 full text RCTs. Thirteen RCTs rated with overall low or unclear risk of bias were synthesized. Assessing individual exercise types (predominantly very low certainty evidence), pain reduction was associated with aerobic exercise and Pilates vs. no intervention, and motor control exercise vs. sham. Improved function was associated with mixed exercise vs. usual care, and Pilates vs. no intervention. Temporary increased minor pain was associated with mixed exercise vs. no intervention, and yoga vs. usual care. Little to no difference was found for other comparisons and outcomes. When pooling exercise types, exercise vs. no intervention probably reduces pain in adults (8 RCTs, SMD = - 0.33, 95% CI - 0.58 to - 0.08) and functional limitations in adults and older adults (8 RCTs, SMD = - 0.31, 95% CI - 0.57 to - 0.05) (moderate certainty evidence).

CONCLUSIONS

With moderate certainty, structured exercise programs probably reduce pain and functional limitations in adults and older people with CPLBP.

Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Needling Therapies for Chronic Primary Low Back Pain in Adults

PURPOSE

Evaluate benefits and harms of needling therapies (NT) for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline.

METHODS

Electronic databases were searched for randomized controlled trials (RCTs) assessing NT compared with placebo/sham, usual care, or no intervention (comparing interventions where the attributable effect could be isolated). We conducted meta-analyses where indicated and graded the certainty of evidence.

RESULTS

We screened 1831 citations and 109 full text RCTs, yeilding 37 RCTs. The certainty of evidence was low or very low across all included outcomes. There was little or no difference between NT and comparisons across most outcomes; there may be some benefits for certain outcomes. Compared with sham, NT improved health-related quality of life (HRQoL) (physical) (2 RCTs; SMD = 0.20, 95%CI 0.07; 0.32) at 6 months. Compared with no intervention, NT reduced pain at 2 weeks (21 RCTs; MD = - 1.21, 95%CI - 1.50; - 0.92) and 3 months (9 RCTs; MD = - 1.56, 95%CI - 2.80; - 0.95); and reduced functional limitations at 2 weeks (19 RCTs; SMD = - 1.39, 95%CI - 2.00; - 0.77) and 3 months (8 RCTs; SMD = - 0.57, 95%CI - 0.92; - 0.22). In older adults, NT reduced functional limitations at 2 weeks (SMD = - 1.10, 95%CI - 1.71; - 0.48) and 3 months (SMD = - 1.04, 95%CI - 1.66; - 0.43). Compared with usual care, NT reduced pain (MD = - 1.35, 95%CI - 1.86; - 0.84) and functional limitations (MD = - 2.55, 95%CI - 3.70; - 1.40) at 3 months.

CONCLUSION

Based on low to very low certainty evidence, adults with CPLBP experienced some benefits in pain, functioning, or HRQoL with NT; however, evidence showed little to no differences for other outcomes.

It might take a village: developing a rehabilitation program of care for degenerative cervical radiculopathy from the patient perspective

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.

Patient and provider characteristics associated with therapeutic intervention selection in a chiropractic clinical encounter: a cross-sectional analysis of the COAST and O-COAST study data

BACKGROUND

Chiropractors use a variety of therapeutic interventions in clinical practice. How the selection of interventions differs across musculoskeletal regions or with different patient and provider characteristics is currently unclear. This study aimed to describe how frequently different interventions are used for patients presenting for chiropractic care, and patient and provider characteristics associated with intervention selection.

METHODS

Data were obtained from the Chiropractic Observation and Analysis STudy (COAST) and Ontario (O-COAST) studies: practice-based, cross-sectional studies in Victoria, Australia (2010-2012) and Ontario, Canada (2014-2015). Chiropractors recorded data on patient diagnosis and intervention selection from up to 100 consecutive patient visits. The frequency of interventions selected overall and for each diagnostic category (e.g., different musculoskeletal regions) were descriptively analysed. Univariable multi-level logistic regression (provider and patient as grouping factors), stratified by diagnostic category, was used to assess the association between patient/provider variables and intervention selection.

RESULTS

Ninety-four chiropractors, representative of chiropractors in Victoria and Ontario for age, sex, and years in practice, participated. Data were collected on 7,966 patient visits (6419 unique patients), including 10,731 individual diagnoses (mean age: 43.7 (SD: 20.7), 57.8% female). Differences in patient characteristics and intervention selection were observed between chiropractors practicing in Australia and Canada. Overall, manipulation was the most common intervention, selected in 63% (95%CI:62-63) of encounters. However, for musculoskeletal conditions presenting in the extremities only, soft tissue therapies were more commonly used (65%, 95%CI:62-68). Manipulation was less likely to be performed if the patient was female (OR:0.74, 95%CI:0.65-0.84), older (OR:0.79, 95%CI:0.77-0.82), presenting for an initial visit (OR:0.73, 95%CI:0.56-0.95) or new complaint (OR:0.82, 95%CI:0.71-0.95), had one or more comorbidities (OR:0.63, 95%CI:0.54-0.72), or was underweight (OR:0.47, 95%CI:0.35-0.63), or obese (OR:0.69, 95%CI:0.58-0.81). Chiropractors with more than five years clinical experience were less likely to provide advice/education (OR:0.37, 95%CI:0.16-0.87) and exercises (OR:0.17, 95%CI:0.06-0.44).

CONCLUSION

In more than 10,000 diagnostic encounters, manipulation was the most common therapeutic intervention for spine-related problems, whereas soft tissue therapies were more common for extremity problems. Different patient and provider characteristics were associated with intervention selection. These data may be used to support further research on appropriate selection of interventions for common musculoskeletal complaints.

Assessing cultural competency among Canadian chiropractors: a cross-sectional survey of Canadian Chiropractic Association members

BACKGROUND

There is a paucity of research assessing cultural competency among Canadian chiropractors. Therefore, the aims of this study were to (1) measure cultural competency among Canadian chiropractors, (2) understand chiropractors' perspectives of challenges and attitudes regarding the delivery of chiropractic services to equity-seeking communities, and (3) assess contextual factors associated with cultural competency.

METHODS

We conducted a cross-sectional survey of members of the Canadian Chiropractic Association (CCA) (May-July 2021). The survey instrument consisted of 57 questions related to demographics, cultural competency, perceptions about health disparities, and challenges in delivery of rehabilitation. Cultural competency was measured using the Cultural Awareness and Sensitivity and Cultural Competence Behaviours subscales of the Cultural Competence Assessment Instrument. We conducted a multivariate linear regression to assess factors that may be associated with cultural competency.

RESULTS

A total of 3143 CCA members responded (response rate of 41%). Mean scores for the Cultural Awareness and Sensitivity subscale were 5.8/7 (95% CI 5.7; 5.8) and 4.2/7 (95% CI 4.1; 4.2) for the Cultural Competence Behaviour subscale. Most chiropractors (72-78%) reported observing important cultural health disparities across various care-related outcomes. Cost of services and language were identified as barriers to providing care to equity-seeking communities. Cultural Awareness and Sensitivity scores were weakly associated with gender (men), years of clinical practice, cultural health disparities, the statement "I think some people have an agenda to look for discrimination even where it does not exist (DEI attitudes)," race (Caucasian), and prior DEI training, (R² = 0.15, p < 0.0001). Cultural Competence Behaviour scores were weakly associated with race (Caucasian), cultural health disparities, prior DEI training, increased years of clinical experience, and higher Cultural Awareness and Sensitivity scores (R² = 0.19, p < 0.0001).

CONCLUSION

This study provides the first description of cultural competency within the chiropractic profession in Canada. Findings suggest a gap between knowledge and behaviour and uncover several barriers and challenges that may inform the development of profession-specific training in cultural competence.

Diversity of the chiropractic profession in Canada: a cross-sectional survey of Canadian Chiropractic Association members

BACKGROUND

Little is known about the diversity of the chiropractic profession with respect to gender, sexual orientation, race, ethnicity and community of practice. This knowledge is important as profession representation of key equity seeking groups may impact quality of care and access for vulnerable communities. The aim of this cross-sectional survey was to explore the diversity of the chiropractic profession in Canada.

METHODS

All registered members of the Canadian Chiropractic Association (N = 7721) were invited to participate in a web-based survey between May and June 2021. Survey questions explored diversity with respect to personal demographics (age, sex, gender, sexual orientation, race, ethnicity, language) and practice characteristics (community setting, practice type). Where possible, survey data was compared to data from the 2016 Census of the Canadian population.

RESULTS

We received a total of 3143 survey responses (response rate-41%). The average age of our sample was 44.7 years (standard deviation 12.7). Forty-five percent were female with the same proportion (45.2%) self-identifying as women. Ninety-one percent of the sample self-identified as heterosexual. With respect to race, 80% of respondents were Caucasian. Seventy percent of chiropractors in our sample identified with Canadian ancestry and 29% with European ancestry. In comparison to the Canadian population, some visible minorities were underrepresented. The greatest discrepancy between the Canadian population and our sample was in the proportion of Black and Indigenous chiropractors. With respect to ethnicity, chiropractors identifying themselves with Canadian ancestry were overrepresented in our sample compared to others, specifically those with North American Indigenous and South, Central and Latin American ancestry. Sixty-one percent of chiropractors practiced in major cities and most work in interdisciplinary clinics (42% Complementary and Alternative Medicine and 33% rehabilitation).

CONCLUSIONS

This study provides an initial description of diversity within the chiropractic profession in Canada. Women represent less than 50% of the profession nationally. Overall, there is little racial and ethnic diversity in the chiropractic profession compared to the Canadian population, with Black and Indigenous peoples being underrepresented. Future work should focus strategies to foster the development of a more diverse chiropractic workforce.

Developing key performance indicators for the Canadian chiropractic profession: a modified Delphi study

Background

The purpose of this study is to develop a list of performance indicators to assess the status of the chiropractic profession in Canada.

Method

We conducted a 4-round modified Delphi technique (March 2018–January 2020) to reach consensus among experts and stakeholders on key status indicators for the chiropractic profession using online questionnaires. During the first round, experts suggested indicators for preidentified themes. Through the following two rounds, the importance and feasibility of each indicator was rated on an 11-point Likert scale, and their related potential sources of data identified. In the final round, provincial stakeholders were recruited to rate the importance of the indicators within the 90th percentile and identified those most important to their organisation.

Results

The first round generated 307 preliminary indicators of which 42 were selected for the remaining rounds, and eleven were preferentially selected by most of the provincial stakeholders. Experts agreed the feasibility of all indicators was high, and that data could be collected through a combination of data obtained from professional liability insurance records and survey(s) of the general population, patients, and chiropractors.

Conclusions

A set of performance indicators to assess the status of the Canadian chiropractic profession emerged from a scientific and stakeholder consensus.

Adherence to spinal imaging guidelines and utilization of lumbar spine diagnostic imaging for low back pain at a Canadian Chiropractic College: a historical clinical cohort study

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.

Integrating Indigenous healing practices within collaborative care models in primary healthcare in Canada: a rapid scoping review

OBJECTIVES

In November 2020, a series of reports, In Plain Sight, described widespread Indigenous-specific stereotyping, racism and discrimination limiting access to medical treatment and negatively impacting the health and wellness of Indigenous Peoples in British Columbia, Canada. To address the health inequalities experienced by Indigenous peoples, Indigenous healing practices must be integrated within the delivery of care. This rapid scoping review aimed to identify and synthesise strategies used to integrate Indigenous healing practices within collaborative care models available in community-based primary healthcare, delivered by regulated health professionals in Canada.

ELIGIBILITY CRITERIA

We included quantitative, qualitative and mixed-methods studies conducted in community-based primary healthcare practices that used strategies to integrate Indigenous healing practices within collaborative care models.

SOURCES OF EVIDENCE

We searched MEDLINE, Embase, Indigenous Studies Portal, Informit Indigenous Collection and Native Health Database for studies published from 2015 to 2021.

CHARTING METHODS

Our data extraction used three frameworks to categorise the findings. These frameworks defined elements of integrated healthcare (ie, functional, organisational, normative and professional), culturally appropriate primary healthcare and the extent of community engagement. We narratively summarised the included study characteristics.

RESULTS

We identified 2573 citations and included 31 in our review. Thirty-nine per cent of reported strategies used functional integration (n=12), 26% organisational (n=8), 19% normative (n=6) and 16% professional (n=5). Eighteen studies (58%) integrated all characteristics of culturally appropriate Indigenous healing practices into primary healthcare. Twenty-four studies (77%) involved Indigenous leadership or collaboration at each phase of the study and, seven (23%) included consultation only or the level of engagement was unclear.

CONCLUSIONS

We found that collaborative and Indigenous-led strategies were more likely to facilitate and implement the integration of Indigenous healing practices. Commonalities across strategies included community engagement, elder support or Indigenous ceremony or traditions. However, we did not evaluate the effectiveness of these strategies.

Exploring clinician perceptions of a care pathway for the management of shoulder pain: a qualitative study

BACKGROUND

Clinical care pathways may be useful tools to improve the quality of healthcare by facilitating the translation of evidence into practice. Our study is situated within a larger project, whereby end-users co-developed a care pathway for the management of shoulder pain. In this study, we explored end-user perceptions of the usefulness and practicality of implementing a care pathway to manage shoulder pain. We also solicited feedback for the pathway's improvement.

METHODS

We conducted a qualitative study using a transcendental phenomenological approach seen through a constructivist lens. Clinicians recorded themselves interacting with the care pathway while working through a clinical case. Clinicians described their thoughts and movements aloud as they completed the activity. Second, we conducted individual semi-structured interviews to discuss the usefulness and practicality of pathway implementation. Interview transcripts were coded independently by reviewers. Transcript codes and associated quotes were grouped into themes. Themes were sequenced and linked creating a 'web' of thematic connections. Summary statements were developed to synthesize the overall essence of the phenomena.

RESULTS

Nine clinicians participated. Participants included eight chiropractors and one medical physician. We found that clinicians believed the care pathway could be useful at various levels, including education (students, interns), for early career clinicians, for engaging patients, facilitating interprofessional communication, and as a reminder of information for certain, less familiar conditions. When discussing the practicality of implementing the care pathway into practice settings, clinicians expressed that agreement with the care pathway and its recommendations may influence its acceptability among clinicians. Additionally, integrating recommendations into practice may be a skill requirement included into clinical training. Clinicians described the importance of opinion leaders in the acceptability of new evidence. Various difficulties with the replicability of interventions into clinical care was also discussed. In general, clinicians suggested the layout of the care pathway was manageable, and there was sufficient information for clinical decision-making. Clinicians also made several recommendations for improvement.

CONCLUSIONS

End-user involvement and collaboration provides tangible instruction to improve care pathways themselves, their implementation strategies and helps to support and strengthen future research for overcoming individual, systemic and contextual barriers.

I expected to be pain free: a qualitative study exploring athletes' expectations and experiences of care received by sports chiropractors

Background

Knowledge about patient satisfaction and experience with care they receive can guide practitioners in establishing doctor-patient relationships and improve health outcomes. Although evidence suggests high patient satisfaction with chiropractic care in general, there is limited understanding of the expectations and experiences of athletes receiving sports chiropractic care.

Objective

To explore the athletes’ expectations and experiences with care received from sports chiropractors, and their perceptions of relevant areas of future research.

Methods

A qualitative study was conducted through an interpretivist lens exploring the perspectives of elite and competitive athletes receiving care from sports chiropractors in Canada. Participants were purposively recruited and interviewed until saturation was reached. Two research team members independently analyzed the interview transcripts using a conventional approach to content analysis. Content was inductively coded and discussed by the research team to generate categories.

Results

We interviewed 18 participants between December 2018 and March 2020, 14 were national level athletes participating in sports ranging from paddling to combat sports. Reported reasons for seeking care included acute care, injury prevention, enhancing performance and maintenance care. Generated categories were organized under topics of experience with care, expectations of care, and research agenda. Participants experienced a variety of interventions, reassurance, varying treatment times, and reported positive impact on their athletic performance. They expected musculoskeletal assessment and treatment including at and beyond the injury site, symptom improvement, good communication and expertise from the chiropractor. Some participants suggested interpersonal and interprofessional communication can be improved, in particular the level of collaboration with other members of their health care team. Overall, participants reported a high level of trust and satisfaction with care received from sports chiropractors. From our participants’ perspective, suggested areas of research should focus on injury mechanics and prevention, impact of care on performance, and interprofessional collaboration.

Conclusions

In general, participants were very satisfied with care. Overall, participants’ expectations and experiences aligned but changed over time. Addressing the findings of this study can be used to enhance the quality of care provided to athletes from sports chiropractors, as well as inform future research agendas. Further work assessing if athletes in other competitive levels have similar experiences and expectations is needed.

The Impact of Moderate and High Intensity Cardiovascular Exertion on Sub-Elite Soccer Referee's Cognitive Performance: A Lab-Based Study

Soccer referees represent a specialized population who are required to perform decisional or perceptual tasks during physical exertion. Recent studies have demonstrated that submaximal acute exercise has a positive impact on cognitive performance. However, less is known about the impact of more strenuous exertion on cognitive performance. This study assessed the effect of moderate and maximal intensity exercise exertion on a cognitive performance in sub-elite soccer referees. Twelve experienced soccer referees (4 female, 8 male) were recruited. Data were collected on 2 separate days. Baseline fitness level was assessed by a standardized aerobic capacity test (VO_2max Test) on Day 1, along with practice trials of the Stroop Color Word Test (Stroop Test) for evaluating cognitive performance. On Day 2, cognitive performance was assessed before, during, and after an incremental intensity exercise protocol based on the Fédération International de Football Association (FIFA) referee fitness test. Relative to results obtained at rest performance on the Stroop Test improved at moderate exertion and at maximal exertion during the modified FIFA fitness test (F = 18.97, p = .005). Mean time to completion (in seconds) of the interference Stroop task significantly improved (p < .05) between rest and moderate exertion [-3.0 ± 3.0 seconds] and between rest and maximal exertion [-4.8 ± 2.6 seconds]. In summary, we observed that cognitive performance was found to improve when sub-elite soccer referees performed moderate and maximal exercise relative to results obtained at rest. It is possible that referees focus their attention to improve goal-oriented processing in the brain during physical exertion.

"Doing our best for patient safety": An international and interprofessional qualitative study with spinal manipulative therapy providers in community-based settings

BACKGROUND

Patient safety research is expanding from hospitals to community-based healthcare settings. Knowledge gaps persist among manual therapy professions that may impede patient safety initiatives within musculoskeletal care settings.

OBJECTIVES

To describe perceptions of patient safety among chiropractors and physiotherapists who provide spinal manipulation therapy (SMT).

DESIGN

Qualitative descriptive study.

METHOD

Cross-sectional data were collected using the SafetyNET Survey to Support Quality Improvement. SMT providers (n = 705) in 3 countries completed surveys, with 84 providing written responses to an open-ended question about patient safety. Qualitative thematic analysis described providers' perceptions about patient safety within their practice.

RESULTS

SMT providers' perceptions were influenced by professional, patient, and practice setting factors. Five themes and 10 supporting categories were developed. Doing Our Best for Patient Safety concerned Avoiding Mistakes and Prioritizing Safety.Putting Patients First focused on Developing Relationships and Individualizing Care.Working and Learning Together advocated for Interprofessional Communication and Collaborative Learning. Organizing Practice Processes emphasized Standardizing Procedures and Benchmarking Progress.Considering Practitioner Identity highlighted how Recognizing Difference among SMT providers and Challenging Fears of other healthcare professionals and patients about SMT were important for enhancing patient safety.

CONCLUSION

Findings align with World Health Organization guiding principles that the nature of healthcare settings influence patient safety strategies. Most responses focused on individual strategies to prevent adverse events. However, this approach may overlook the benefits of identifying and documenting adverse events, setting time to discuss adverse events with clinic members, standardizing clinical practices, and building transparent patient safety cultures across healthcare professions and settings.

Are Nonpharmacologic Interventions Delivered Through Synchronous Telehealth as Effective and Safe as In-Person Interventions for the Management of Patients With Nonacute Musculoskeletal Conditions? A Systematic Rapid Review

OBJECTIVE

To determine whether nonpharmacologic interventions delivered through synchronous telehealth are as effective and safe compared with in-person interventions for the management of patients with musculoskeletal conditions in improving pain, functioning, self-reported recovery, psychological outcomes, or health-related quality of life using rapid review methods.

DATA SOURCES

We searched MEDLINE, CINAHL, Embase, and Cochrane Central Register of Controlled Trials from 2010 to August 2020 for randomized controlled trials (RCTs) published in English or French; we updated our search in January 2021.

STUDY SELECTION

One reviewer screened citations in 2 phases (phase 1: title/abstract; phase 2: full-text) selecting RCTs comparing synchronous telehealth with in-person care for the management of musculoskeletal conditions. A random 10% sample was screened by 2 independent reviewers with minimum 95% agreement prior to full screening. One reviewer critically appraised and one reviewer validated appraisal for eligible RCTs.

DATA EXTRACTION

One author extracted participant characteristics, setting, sample size, interventions, comparisons, follow-up period, and outcome data. A second author validated data extraction.

DATA SYNTHESIS

We summarized the findings narratively. Low- to moderate-quality evidence suggests that synchronous telehealth (ie, videoconference or telephone calls) alone or in combination with in-person care leads to similar outcomes as in-person care alone for nonspecific low back pain, generalized osteoarthritis, hip or knee osteoarthritis, and nonacute headaches in adults.

CONCLUSIONS

Synchronous telehealth may be an option for the management of nonacute musculoskeletal conditions in adults. However, our results may not be generalizable to rural or low socioeconomic populations. Future research should investigate the outcomes associated the use of new technologies, such as videoconference.

Exploring clinicians' experiences and perceptions of end-user roles in knowledge development: a qualitative study

Background

End-user involvement in developing evidence-based tools for clinical practice may result in increased uptake and improved patient outcomes. Understanding end-user experiences and perceptions about the co-production of knowledge is useful to further the science of integrated knowledge translation (iKT) – a strategy for accelerating the uptake and impact of research. Our study had two main objectives: (1) explore end-user (clinician) experiences of co-producing an evidence-based practice tool; and (2) describe end-user perceptions in knowledge development.

Methods

We used a qualitative study design. We conducted semi-structured interviews with clinicians and used a transcendental phenomenological approach to analyze themes/phenomena. In addition, we explored the interrelated themes between the thematic maps of each objective.

Results

Four themes emerged from clinicians’ experiences in co-producing the practice tool: ease/convenience of participating, need for support and encouragement, understanding the value of participating, and individual skillsets yield meaningful contributions. Stakeholder roles in knowledge tool development and improving dissemination of evidence and knowledge tools were themes that related to clinician perceptions in knowledge development. The review of interrelated thematic maps depicts an intertwined relationship between stakeholders and dissemination.

Conclusions

End-users provide invaluable insight and perspective into the development of evidence-based clinical tools. Exploring the experiences and perceptions of end-users may support future research endeavours involving iKT, such as the co-production of clinical resources, potentially improving uptake and patient health outcomes.

Noninvasive management of soft tissue disorders of the shoulder: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration

OBJECTIVES

Objective of this study is to develop an evidence-based guideline for the noninvasive management of soft tissue disorders of the shoulder (shoulder pain), excluding major pathology.

METHODS

This guideline is based on high-quality evidence from seven systematic reviews. Multidisciplinary experts considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience is clinicians; target population is adults with shoulder pain.

RESULTS

When managing patients with shoulder pain, clinicians should (a) rule out major structural or other pathologies as the cause of shoulder pain and reassure patients about the benign and self-limited nature of most soft tissue shoulder pain; (b) develop a care plan in partnership with the patient; (c) for shoulder pain of any duration, consider low-level laser therapy; multimodal care (heat/cold, joint mobilization, and range of motion exercise); cervicothoracic spine manipulation and mobilization for shoulder pain when associated pain or restricted movement of the cervicothoracic spine; or thoracic spine manipulation; (d) for shoulder pain >3-month duration, consider stretching and/or strengthening exercises; laser acupuncture; or general physician care (information, advice, and pharmacological pain management if necessary); (e) for shoulder pain with calcific tendinitis on imaging, consider shock-wave therapy; (f) for shoulder pain of any duration, do not offer ultrasound; taping; interferential current therapy; diacutaneous fibrolysis; soft tissue massage; or cervicothoracic spine manipulation and mobilization as an adjunct to exercise (i.e., range of motion, strengthening and stretching exercise) for pain between the neck and the elbow at rest or during movement of the arm; (g) for shoulder pain >3-month duration, do not offer shock-wave therapy; and (h) should reassess the patient's status at each visit for worsening of symptoms or new physical, mental, or psychological symptoms, or satisfactory recovery.

CONCLUSIONS

Our evidence-based guideline provides recommendations for non-invasive management of shoulder pain. The impact of the guideline in clinical practice requires further evaluation.

SIGNIFICANCE

Shoulder pain of any duration can be effectively treated with laser therapy, multimodal care (i.e., heat/cold, joint mobilization, range of motion exercise), or cervicothoracic manipulation and mobilization. Shoulder pain (>3 months) can be effectively treated with exercises, laser acupuncture, or general physician care (information, advice, and pharmacological pain management if necessary).

Contextualizing the lived experiences of patients with low back pain from different countries according to the ICF framework

Objective

To explore perspectives, including social and psychological aspects, of patients seeking manual care for low back pain, in order to understand constructs of functioning that are important across different cultural contexts. The International Classification of Functioning, Disability and Health (ICF) emphasizes the importance of these aspects to describe health-related functioning.

Design

Focus group interviews.

Patients

Patients from Botswana, Canada and Norway seeking manual care for their low back pain. Methods: Interviews were conducted in the 3 countries, transcribed verbatim, translated into English, and linked to the ICF according to established rules.

Results

Seven focus groups yielded 1,863 meaningful concepts that were linked to ICF categories. The largest proportion of responses linked to the Activities and Participation domain. The most frequently mentioned chapters related to pain and its mental aspects, suggesting that the psychological impact of living with low back pain is important to patients.

Conclusion

Despite cultural differences, patients seeking manual care for low back pain in Botswana, Canada and Norway reported similar experiences of disability across ICF domains. The relatively high ranking of psychosocial factors highlights their importance for patients, in addition to factors of biological origin, and indicates that the contextual nature of the lived experience of low back pain may not be covered in standard examinations used in manual medicine.

The profile of older adults seeking chiropractic care: a secondary analysis

BACKGROUND

Musculoskeletal conditions are the primary reason older adults seek general medical care, resulting in older adults as the highest consumers of health care services. While there is high use of chiropractic care by older adults, there is no recent, specific data on why older adults seek chiropractic care and how chiropractors manage conditions. Therefore, the purpose of this study was to describe the demographic characteristics of older adults seeking chiropractic care, and to report problems diagnosed by chiropractors and the treatment provided to older adults who seek chiropractic care.

METHODS

A secondary data analysis from two, large cross-sectional observational studies conducted in Australia (COAST) and Canada (O-COAST). Patient encounter and diagnoses were classified using the International Classification of Primary Care, 2nd edition (ICPC-2), using the Australian ICPC-2 PLUS general practice terminology and the ICPC-2 PLUS Chiro terminology. Descriptive statistics were used to summarize chiropractor, patient and encounter characteristics. Encounter and patient characteristics were compared between younger (< 65 years old) and older (≥65 years old) adults using χ² tests or t-tests, accounting for the clustering of patients and encounters within chiropractors.

RESULTS

A total of 6781 chiropractor-adult patient encounters were recorded. Of these, 1067 encounters were for persons aged > 65 years (16%), from 897 unique older patients. The most common diagnosis within older adult encounters was a back problem (56%), followed by neck problems (10%). Soft tissue techniques were most frequently used for older patients (85 in every 100 encounters) and in 29 of every 100 encounters, chiropractors recommended exercise to older patients as a part of their treatment.

CONCLUSIONS

From 6781 chiropractor-adult patient encounters across two countries, one in seven adult chiropractic patients were > 65 years. Of these, nearly 60% presented with a back problem, with neck pain and lower limb problems the next most common presentation to chiropractors. Musculoskeletal conditions have a significant burden in terms of disability in older adults and are the most commonly treated conditions in chiropractic practice. Future research should explore the clinical course of back pain in older patients seeking chiropractic care and compare the provision of care to older adults across healthcare professions.

Assessment of Studies Evaluating Spinal Manipulative Therapy and Infectious Disease and Immune System Outcomes: A Systematic Review

IMPORTANCE

Claims that spinal manipulative therapy (SMT) can improve immune function have increased substantially during the COVID-19 pandemic and may have contributed to the rapid spread of both accurate and inaccurate information (referred to as an infodemic by the World Health Organization).

OBJECTIVE

To identify, appraise, and synthesize the scientific literature on the efficacy and effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes in patients with infectious disease and to examine the association between SMT and selected immunological, endocrine, and other physiological biomarkers.

EVIDENCE REVIEW

A literature search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Index to Chiropractic Literature, the Cochrane Central Register of Controlled Trials, and Embase was conducted from inception to April 15, 2020. Randomized clinical trials and cohort studies were included. Eligible studies were critically appraised, and evidence with high and acceptable quality was synthesized using the Synthesis Without Meta-Analysis guideline.

FINDINGS

A total of 2593 records were retrieved; after exclusions, 50 full-text articles were screened, and 16 articles reporting the findings of 13 studies comprising 795 participants were critically appraised. The literature search found no clinical studies that investigated the efficacy or effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes among patients with infectious disease. Eight articles reporting the results of 6 high- and acceptable-quality RCTs comprising 529 participants investigated the effect of SMT on biomarkers. Spinal manipulative therapy was not associated with changes in lymphocyte levels or physiological markers among patients with low back pain or participants who were asymptomatic compared with sham manipulation, a lecture series, and venipuncture control groups. Spinal manipulative therapy was associated with short-term changes in selected immunological biomarkers among asymptomatic participants compared with sham manipulation, a lecture series, and venipuncture control groups.

CONCLUSIONS AND RELEVANCE

In this systematic review of 13 studies, no clinical evidence was found to support or refute claims that SMT was efficacious or effective in changing immune system outcomes. Although there were limited preliminary data from basic scientific studies suggesting that SMT may be associated with short-term changes in immunological and endocrine biomarkers, the clinical relevance of these findings is unknown. Given the lack of evidence that SMT is associated with the prevention of infectious diseases or improvements in immune function, further studies should be completed before claims of efficacy or effectiveness are made.

Using technology-based educational interventions to improve knowledge about clinical practice guidelines

OBJECTIVE

To describe the best evidence on the effectiveness of technology-based learning tools designed to improve knowledge of health care providers about clinical practice guidelines (CPGs).

METHODS

We conducted a systematic review, searching MEDLINE, Embase, and CINAHL from inception to July 2018. Included studies investigated the effectiveness of any technology-based learning tools developed to improve knowledge of health care providers about CPGs. We used a 2-phase screening process to determine eligibility. Pairs of reviewers critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network checklist for randomized controlled trials or the National Institutes of Health checklist for pre- and postintervention trials. Evidence from internally valid studies was described using a best-evidence summary. We conducted a sensitivity analysis to determine whether results varied according to methodological quality.

RESULTS

Twenty-five of 8321 articles met our selection criteria. Six studies had a low risk of bias and were included in this review. Spaced education was associated with improvement in knowledge; however, its effectiveness relative to other interventions is unknown. Module-based online educational interventions were associated with improvement in knowledge of CPGs; however, they may not be more effective than paper-based self-learning or in-person workshops. The sensitivity analysis determined that the evidence was similar between the high and low risk of bias studies.

CONCLUSION

Module-based- and spaced-education interventions may be beneficial for improving health care providers' knowledge of CPGs; however, much of the evidence toward their use is preliminary.

The global summit on the efficacy and effectiveness of spinal manipulative therapy for the prevention and treatment of non-musculoskeletal disorders: a systematic review of the literature

Background

A small proportion of chiropractors, osteopaths, and other manual medicine providers use spinal manipulative therapy (SMT) to manage non-musculoskeletal disorders. However, the efficacy and effectiveness of these interventions to prevent or treat non-musculoskeletal disorders remain controversial.

Objectives

We convened a Global Summit of international scientists to conduct a systematic review of the literature to determine the efficacy and effectiveness of SMT for the primary, secondary and tertiary prevention of non-musculoskeletal disorders.

Global summit

The Global Summit took place on September 14–15, 2019 in Toronto, Canada. It was attended by 50 researchers from 8 countries and 28 observers from 18 chiropractic organizations. At the summit, participants critically appraised the literature and synthesized the evidence.

Systematic review of the literature

We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, the Cumulative Index to Nursing and Allied Health, and the Index to Chiropractic Literature from inception to May 15, 2019 using subject headings specific to each database and free text words relevant to manipulation/manual therapy, effectiveness, prevention, treatment, and non-musculoskeletal disorders. Eligible for review were randomized controlled trials published in English. The methodological quality of eligible studies was assessed independently by reviewers using the Scottish Intercollegiate Guidelines Network (SIGN) criteria for randomized controlled trials. We synthesized the evidence from articles with high or acceptable methodological quality according to the Synthesis without Meta-Analysis (SWiM) Guideline. The final risk of bias and evidence tables were reviewed by researchers who attended the Global Summit and 75% (38/50) had to approve the content to reach consensus.

Results

We retrieved 4997 citations, removed 1123 duplicates and screened 3874 citations. Of those, the eligibility of 32 articles was evaluated at the Global Summit and 16 articles were included in our systematic review. Our synthesis included six randomized controlled trials with acceptable or high methodological quality (reported in seven articles). These trials investigated the efficacy or effectiveness of SMT for the management of infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. None of the trials evaluated the effectiveness of SMT in preventing the occurrence of non-musculoskeletal disorders. Consensus was reached on the content of all risk of bias and evidence tables. All randomized controlled trials with high or acceptable quality found that SMT was not superior to sham interventions for the treatment of these non-musculoskeletal disorders. Six of 50 participants (12%) in the Global Summit did not approve the final report.

Conclusion

Our systematic review included six randomized clinical trials (534 participants) of acceptable or high quality investigating the efficacy or effectiveness of SMT for the treatment of non-musculoskeletal disorders. We found no evidence of an effect of SMT for the management of non-musculoskeletal disorders including infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. This finding challenges the validity of the theory that treating spinal dysfunctions with SMT has a physiological effect on organs and their function. Governments, payers, regulators, educators, and clinicians should consider this evidence when developing policies about the use and reimbursement of SMT for non-musculoskeletal disorders.

Methodological flaws on "manual therapy for the pediatric population: a systematic review" by Prevost et al. (2019)

Prevost et al. published a systematic review evaluating the use of manual therapy for clinical conditions in the pediatric population in 2019. However, several methodological flaws in the conduct of the review limit the internal validity of its conclusions. We caution readers about the validity of the recommendations and suggest that the review not be used to inform the clinical management of pediatric patients.

Investigator analytic repeatability of two new intervertebral motion biomarkers for chronic, nonspecific low back pain in a cohort of healthy controls

Background

Understanding the mechanisms underlying chronic, nonspecific low back pain (CNSLBP) is essential to advance personalized care and identify the most appropriate intervention. Recently, two intervertebral motion biomarkers termed “Motion Sharing Inequality” (MSI) and “Motion Sharing Variability” (MSV) have been identified for CNSLBP using quantitative fluoroscopy (QF). The aim of this study was to conduct intra- and inter-investigator analytic repeatability studies to determine the extent to which investigator error affects their measurement in clinical studies.

Methods

A cross-sectional cohort study was conducted using the image sequences of 30 healthy controls who received QF screening during passive recumbent flexion motion. Two independent investigators analysed the image sequences for MSI and MSV from October to November 2018. Intra and inter- investigator repeatability studies were performed using intraclass correlations (ICC), standard errors of measurement (SEM) and minimal differences (MD).

Results

Intra-investigator ICCs were 0.90 (0.81,0.95) (SEM 0.029) and 0.78 (0.59,0.89) (SEM 0.020) for MSI and MSV, respectively. Inter-investigator ICCs 0.93 (0.86,0.97) (SEM 0.024) and 0.55 (0.24,0.75) (SEM 0.024). SEMs for MSI and MSV were approximately 10 and 30% of their group means respectively. The MDs for MSI for intra- and inter-investigator repeatability were 0.079 and 0.067, respectively and for MSV 0.055 and 0.067.

Conclusions

MSI demonstrated substantial intra- and inter-investigator repeatability, suggesting that investigator input has a minimal influence on its measurement. MSV demonstrated moderate intra-investigator reliability and fair inter-investigator repeatability. Confirmation in patients with CNSLBP is now required.

Reported 1-year prevalence of occupational musculoskeletal disorders in Ontario chiropractors

Background

Chiropractors are a particular subset of health care professionals that reportedly suffer occupational musculoskeletal disorders (MSDs), yet they have received minimal attention to date regarding mitigating risks of occupational injury. Our study determined the prevalence of occupationally-related MSDs in the preceding year, their bodily distribution, severity, and practice-related changes in practicing chiropractors in the province of Ontario.

Methods

We conducted a cross-sectional survey of chiropractors who were members of the Ontario Chiropractic Association (OCA) from January to March 2019. A three-part online survey was developed to ask chiropractors about specific details of MSDs they experienced in the past year and any practice-related changes they made as a result. Responses from participants provided both quantitative and qualitative data. Prevalence estimates were derived for quantitative data. Qualitative data were stratified by themes that were further divided into categories and subcategories. Demographic variables of the respondents and OCA membership were compared to determine representativeness.

Results

From the 432 responses (11.8% response rate), 59.1% reported experiencing an occupationally-related MSD in the past year. Survey respondents were demographically representative of the OCA membership. MSDs were most commonly reported for the lower back (38.3%), wrists/hands (38.1%) and neck (37.4%). Positioning/performing manipulation was the most common occupational activity for MSD of the upper extremity (53.1%) and lower back (34.8%). Chiropractors largely reported their MSDs did not prevent them from doing their normal work (77.4%), despite the fact that 43.2% reported experiencing their MSDs for more than 30 days in the previous year. Common reported work modifications were grouped under themes of practice and physical changes. Practice changes included reducing patient volume, hiring personnel and scheduling. Physical changes included using different office equipment, selecting different techniques requiring lower force and altering their hand contacts or body position when treating patients.

Conclusions

One-year prevalence of occupational MSDs from this study are comparable to previously reported estimates in chiropractors. These data suggest that chiropractors continue with their regular workload despite their MSDs, thereby increasing their chances of presenteeism. Chiropractors changing technique or technique parameters due to their MSDs provides direction for future research to reduce exposure to occupational MSD risk factors.

Rehabilitative management of back pain in children: protocol for a mixed studies systematic review

INTRODUCTION

Little is known about effective, efficient and acceptable management of back pain in children. A comprehensive and updated evidence synthesis can help to inform clinical practice.

OBJECTIVE

To inform clinical practice, we aim to conduct a systematic review of the literature and synthesise the evidence regarding effective, cost-effective and safe rehabilitation interventions for children with back pain to improve their functioning and other health outcomes.

METHODS AND ANALYSIS

We will search MEDLINE, Embase, PsycINFO, CINAHL, the Index to Chiropractic Literature, the Cochrane Controlled Register of Trials and EconLit for primary studies published from inception in all languages. We will include quantitative studies (randomised controlled trials, cohort and case-control studies), qualitative studies, mixed-methods studies and full economic evaluations. To augment our search of the bibliographic electronic databases, we will search reference lists of included studies and relevant systematic reviews, the WHO International Clinical Trials Registry Platform and consult with content experts. We will assess the risk of bias using appropriate critical appraisal tools. We will extract data about study and participant characteristics, intervention type and comparators, context and setting, outcomes, themes and methodological quality assessment. We will use a sequential approach at the review level to integrate data from the quantitative, qualitative and economic evidence syntheses.

ETHICS AND DISSEMINATION

Ethics approval is not required. We will disseminate findings through activities, including (1) presentations in national and international conferences; (2) meetings with national and international decision makers; (3) publications in peer-reviewed journals and (4) posts on organisational websites and social media.

Patient safety in chiropractic teaching programs: a mixed methods study

Background

Patient safety research has lagged within academic settings, including chiropractic teaching institutions. To develop a robust patient safety culture, the Institute of Medicine emphasized the need for employee’s attitudes to be understanding and positive. To initiate the assessment of the current culture and future needs, this study evaluated patient safety attitudes among chiropractic teaching clinic stakeholders (supervising clinicians, student interns, and administrative staff) and compared their standardized survey scores to established medical survey databases.

Methods

We conducted a cross-sectional, mixed methods survey design with quantitative analytic priority. Chiropractic interns, clinical faculty, and clinic staff of 5 international chiropractic educational programs completed a modified version of the Agency for Healthcare Research and Quality (AHRQ) Patient Safety Culture for Medical Offices Survey with open-ended comment fields between 2014 and 2016. Composite means of positive responses were calculated and compared to patient safety, quality of care, and overall self-ratings benchmarks from Canadian providers and academic settings in the AHRQ database. Qualitative responses were thematically categorized for a convergent analysis of quantitative results for the chiropractic sample.

Results

Chiropractic survey response rate was 45.3% (n = 645). Quantitative survey results indicated moderate scores and ranges (57–85%) on all patient safety dimensions for the chiropractic samples. Academic medicine and chiropractic providers’ benchmarks scored higher positive responses than chiropractic teaching clinics on most quantitative dimensions, except for work pressure/pace. Teamwork, organizational learning, and patient tracking/follow-up were the most positively endorsed quantitative dimensions, with communication, staff training, office standardization, and leadership support considered areas for improvement in both settings. Qualitative responses for the chiropractic clinics identified a need for open communication; additional staff training and student involvement in creating safety cultures; standardization of office processes including information exchange, scheduling, and equipment maintenance; and leadership support that focused on decreasing work pressure/pace and setting safety priorities.

Conclusion

As the first report of patient safety attitudes from stakeholders in chiropractic teaching clinics, specific areas of improvement were identified. Chiropractic teaching programs might consider incorporating these and related patient safety concepts into their formal curricula. Mixed methods approach offers teaching clinics opportunities to assess stakeholders’ insights and enhance safe delivery of chiropractic care.

Beliefs, perceptions and practices of chiropractors and patients about mitigation strategies for benign adverse events after spinal manipulation therapy

BACKGROUND

Approximately 50% of patients who receive spinal manipulative therapy (SMT) experience some kind of adverse event (AE), typically benign and transient in nature. Regardless of their severity, mitigating benign AEs is important to improve patient experience and quality of care. The aim of this study was to identify beliefs, perceptions and practices of chiropractors and patients regarding benign AEs post-SMT and potential strategies to mitigate them.

METHODS

Clinicians and patients from two chiropractic teaching clinics were invited to respond to an 11-question survey exploring their beliefs, perceptions and practices regarding benign AEs post-SMT and strategies to mitigate them. Responses were analyzed using descriptive statistics.

RESULTS

A total of 39 clinicians (67% response rate) and 203 patients (82.9% response rate) completed the survey. Most clinicians (97%) believed benign AEs occur, and 82% reported their own patients have experienced one. For patients, 55% reported experiencing benign AEs post-SMT, with the most common symptoms being pain/soreness, headache and stiffness. While most clinicians (61.5%) reported trying a mitigation strategy with their patients, only 21.2% of patients perceived their clinicians had tried any mitigation strategy. Clinicians perceived that patient education is most likely to mitigate benign AEs, followed by soft tissue therapy and/or icing after SMT. Patients perceived stretching was most likely to mitigate benign AEs, followed by education and/or massage.

CONCLUSIONS

This is the first study comparing beliefs, perceptions and practices from clinicians and patients regarding benign AEs post-SMT and strategies to mitigate them. This study provides an important step towards identifying the best strategies to improve patient safety and improve quality of care.

The clinical utility of routine spinal radiographs by chiropractors: a rapid review of the literature

Introduction

When indicated by signs or symptoms of potentially serious underlying pathology (red flags), chiropractors can use radiographs to inform their diagnosis. In the absence of red flags, the clinical utility of routine or repeat radiographs to assess the structure and function of the spine is controversial.

Objectives

To determine the diagnostic and therapeutic utility of routine or repeat radiographs (in the absence of red flags) of the cervical, thoracic or lumbar spine for the functional or structural evaluation of the spine. Investigate whether functional or structural findings on repeat radiographs are valid markers of clinically meaningful outcomes. The research objectives required that we determine the validity, diagnostic accuracy and reliability of radiographs for the structural and functional evaluation of the spine.

Evidence review

We searched MEDLINE, CINAHL, and Index to Chiropractic Literature from inception to November 25, 2019. We used rapid review methodology recommended by the World Health Organization. Eligible studies (cross-sectional, case-control, cohort, randomized controlled trials, diagnostic and reliability) were critically appraised. Studies of acceptable quality were included in our synthesis. The lead author extracted data and a second reviewer independently validated the data extraction. We conducted a qualitative synthesis of the evidence.

Findings

We identified 959 citations, screened 176 full text articles and critically appraised 23. No relevant studies assessed the clinical utility of routine or repeat radiographs (in the absence of red flags) of the cervical, thoracic or lumbar spine for the functional or structural evaluation of the spine. No studies investigated whether functional or structural findings on repeat radiographs are valid markers of clinically meaningful outcomes. Nine low risk of bias studies investigated the validity (n = 2) and reliability (n = 8) of routine or repeat radiographs. These studies provide no evidence of clinical utility.

Conclusion

We found no evidence that the use of routine or repeat radiographs to assess the function or structure of the spine, in the absence of red flags, improves clinical outcomes and benefits patients. Given the inherent risks of ionizing radiation, we recommend that chiropractors do not use radiographs for the routine and repeat evaluation of the structure and function of the spine.

A united statement of the global chiropractic research community against the pseudoscientific claim that chiropractic care boosts immunity

Background

In the midst of the coronavirus pandemic, the International Chiropractors Association (ICA) posted reports claiming that chiropractic care can impact the immune system. These claims clash with recommendations from the World Health Organization and World Federation of Chiropractic. We discuss the scientific validity of the claims made in these ICA reports.

Main body

We reviewed the two reports posted by the ICA on their website on March 20 and March 28, 2020. We explored the method used to develop the claim that chiropractic adjustments impact the immune system and discuss the scientific merit of that claim. We provide a response to the ICA reports and explain why this claim lacks scientific credibility and is dangerous to the public. More than 150 researchers from 11 countries reviewed and endorsed our response.

Conclusion

In their reports, the ICA provided no valid clinical scientific evidence that chiropractic care can impact the immune system. We call on regulatory authorities and professional leaders to take robust political and regulatory action against those claiming that chiropractic adjustments have a clinical impact on the immune system.

Locus of control in patients with Huntington disease: a cross-sectional study

BACKGROUND

Health locus of control (LOC) represents an individual's beliefs regarding one's ability to influence health outcomes. In patients with chronic and neurodegenerative diseases, greater internal LOC has been associated with lower levels of disability.

OBJECTIVE

To examine LOC in patients with Huntington disease (HD).

METHODS

A cross-sectional study of individuals affected by HD, stratified by disease status, was conducted. Participants completed a demographic questionnaire, the Internal Control Index (ICI), and the Hospital Anxiety and Depression Scales.

RESULTS

Thirty-four subjects completed the study. All groups demonstrated greater internal LOC (measured by ICI scores), and significant differences between groups were observed. Secondary analysis demonstrated relationships between depressive symptoms and anxiety symptoms, and ICI score and time from clinical diagnosis of HD.

CONCLUSION

As patients with chronic pain and neurodegenerative diseases such as HD are likely to present for chiropractic care, identifying factors such as anxiety, depression and LOC may affect patients' response to care.

Clinical management of benign joint hypermobility syndrome: a case series

BACKGROUND

Benign Joint Hypermobility Syndrome (BJHS) is a relatively prevalent condition of the spectrum of heritable connective tissue disorders, with musculoskeletal, visceral and psychological manifestations. The conservative management of the musculoskeletal symptomatology must be modified for optimal effectiveness and minimal sequelae.

PURPOSE

To provide an overview of the presentation, assessment, chiropractic management, and outcomes of patients with BJHS.

STUDY DESIGN

Case series.

DISCUSSION

Recognizing joint hypermobility as a significant contributing factor in patients presenting with musculoskeletal complaints is often challenging. The lack of awareness of BJHS may delay the diagnosis as well as effective management. Manual therapy should be used judiciously; active exercise is an essential element of care. We provide an overview of the presentations, assessment, chiropractic management, and outcomes of three patients with BJHS. Future clinical trials are necessary to determine effective clinical management strategies for patients with BJHS.

"I stay in bed, sometimes all day." A qualitative study exploring lived experiences of persons with disabling low back pain

AIM

To explore the lived experiences of persons with low back pain (LBP) and disability within the context of the International Classification of Function, Disability and Health (ICF) framework.

METHODS

Qualitative study using focus group methodology. We stratified LBP patients into two low (n=9) and one high disability (n=3) groups. Transcript-based thematic analysis was conducted through an interpretivist lens.

RESULTS

Four themes emerged: Invisibility, Ambivalence, Social isolation, and Stigmatization and marginalization. Participants described how environmental factors affected how they experienced disability and how their awareness of people's attitudes affected personal factors and participation in social activities. High disability participants experienced challenges with self-care, employment, and activities. The invisibility of LBP and status loss contributed to depressive symptoms.

CONCLUSION

LBP patients experience physical, social, economic and emotional disability. Our findings highlight the interaction between domains of the ICF framework and the importance of considering these perspectives when managing LBP patients with varying levels of disability.

Postsurgical rehabilitation for adults with low back pain with or without radiculopathy who were treated surgically: protocol for a mixed studies systematic review

INTRODUCTION

Surgical rates for low back pain (LBP) have been increasing in Europe, North America and Asia. Many patients treated surgically will require postsurgical rehabilitation. Little is known about the effectiveness of postsurgical rehabilitation interventions on health outcomes or about patients' experiences with these interventions.

OBJECTIVES

To conduct a mixed studies systematic review of quantitative and qualitative studies regarding: (1) the effectiveness and safety of postsurgical rehabilitation interventions for adults with LBP treated surgically and (2) the experiences of patients, healthcare providers, caregivers or others involved with the rehabilitation.

METHODS AND ANALYSIS

We will search MEDLINE, Embase, PsycINFO, CINAHL, the Index to Chiropractic Literature, the Cochrane Controlled Register of Trials and the Rehabilitation & Sports Medicine Source for peer-reviewed empirical studies published from inception in any language. Studies using quantitative, qualitative and mixed methodologies will be included. We will also search reference lists of all eligible articles. Data extraction will include type of presurgical pathology, indication for surgery, surgical procedure, how the intervention was delivered and by whom, context and setting. We will conduct a quality assessment of each study and consider study quality in our evidence synthesis. We will use a sequential approach at the review level to synthesise and integrate data. First, we will synthesise the quantitative and qualitative studies independently, conducting a meta-analysis of the quantitative studies if appropriate and thematic synthesis of the qualitative studies. Then, we will integrate the quantitative and qualitative evidence by juxtaposing the findings in a matrix.

ETHICS AND DISSEMINATION

Ethical approval is not required for this knowledge synthesis. Findings will be disseminated through knowledge translation activities including: (1) presentations at national and international conferences and scientific meetings; (2) presentations to local and international stakeholders; (3) publications in peer-reviewed journals and (4) posts on organisational websites.
