The biopsychosocial factors associated with development of chronic musculoskeletal pain. An umbrella review and meta-analysis of observational systematic reviews

AIM

The aim of this umbrella review was to establish which biopsychosocial factors are associated with development of chronic musculoskeletal pain.

METHODS

Ovid Medline, Embase, Web of Science Core Collection, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, PsycINFO, CINAHL, PEDro, PROSPERO, Google Scholar and grey literature were searched from database inception to 4th April 2023. Systematic reviews of observational prospective longitudinal studies, including populations with <3 months (not chronic) musculoskeletal pain, investigating biopsychosocial factors that contribute to development of chronic (>3 months) musculoskeletal pain. Two reviewers searched the literature, assessed risk of bias (Assessing the Methodological Quality of Systematic Reviews-2), and evaluated quality (Grading of Recommendations, Assessment, Development and Evaluation) to provide an overall statement on the certainty of evidence for each biopsychosocial factor. Data analysis was performed through random effects meta-analysis (including meta-analysis of meta-analyses where possible) and descriptive synthesis.

RESULTS

13 systematic reviews were included comprising 185 original research studies (n = 489,644 participants). Thirty-four biopsychosocial factors are associated with development of chronic musculoskeletal pain. Meta-analyses of odds and/or likelihood ratios were possible for 25 biopsychosocial factors. There is moderate certainty evidence that smoking (OR 1.24 [95%CI, 1.14-1.34), fear avoidance (LR+ 2.11 [95%CI, 1.59-2.8]; LR- 0.5 [95%CI, 0.35-0.71]) poorer support networks (OR 1.21 [95%CI, 1.14-1.29]), lower socioeconomic status (OR 2.0 [95%CI, 1.64-2.42]), and high levels of pain (OR 5.61 [95%CI, 3.74-8.43]) are associated with development of chronic musculoskeletal pain (all P<0.001). Remaining factors are of low or very low certainty evidence.

CONCLUSIONS AND RELEVANCE

There is moderate certainty evidence that smoking, fear avoidance, poorer support networks, lower socioeconomic status, and high levels of pain are associated with development of chronic musculoskeletal pain. High risk of bias was evident in most included reviews; this highlights the need for higher quality systematic reviews.

Diagnostic utility of diagnostic investigations to identify neuropathic pain in low back-related leg pain: protocol for a systematic review

INTRODUCTION

Neuropathic pain in low back-related leg pain has gained increasing interest in contemporary research. Identification of neuropathic pain in low back-related leg pain is essential to inform precision management. Diagnostic investigations are commonly used to identify neuropathic pain in low back-related leg pain; yet the diagnostic utility of these investigations is unknown. This systematic review aims to investigate the diagnostic utility of diagnostic investigations to identify neuropathic pain in low back-related leg pain.

METHODS AND ANALYSIS

This protocol has been designed and reported in accordance with the Cochrane Handbook for Diagnostic Test Accuracy studies, Centre for Reviews and Dissemination and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols checklist, respectively. The search strategy will involve two independent reviewers searching electronic databases (CINAHL, EMBASE, MEDLINE, Web of Science, Cochrane Library, AMED, Pedro), key journals (Spine, The Clinical Journal of Pain, PAIN, European Journal of Pain, The Journal of Pain, Musculoskeletal Science and Practice) and grey literature (British National Bibliography for report literature, OpenGrey, EThOS) from inception to 31 July 2023 to identify studies. Studies evaluating the diagnostic accuracy of diagnostic investigation to identify neuropathic pain in patients with low back-related leg pain will be eligible, studies not written in English will be excluded. The reviewers will extract the data from included studies, assess risk of bias (Quality Assessment of Diagnostic Accuracy Studies 2) and determine confidence in findings (Grading of Recommendations, Assessment, Development and Evaluation guidelines). Methodological heterogeneity will be assessed to determine if a meta-analysis is possible. If pooling of data is not possible then a narrative synthesis will be done.

ETHICS AND DISSEMINATION

Ethical approval is not required. Findings will be published in a peer-reviewed journal, presented at relevant conferences and shared with the Patient Partner Advisor Group at Western University, Canada.

Outcome measures for young people with adolescent idiopathic scoliosis: A qualitative exploration of healthcare professionals' perceptions and practices

BACKGROUND

Limited knowledge exists on current use of patient reported outcome measures (PROMs) and performance measures for adolescents with idiopathic scoliosis (AIS), as well as health care professionals' (HCPs) perceived barriers and facilitators towards their use. This study's objectives were: 1) to explore current practice of HCPs when assessing outcomes for AIS 2) to understand perceived barriers and facilitators of HCPs to use PROMs 3) to understand perceived barriers and facilitators of HCPs to use performance measures.

METHODS

A qualitative study recruited a purposive sample of HCPs from a tertiary hospital in the United Kingdom. Mean years of experience managing individuals with AIS was 11.8 years; and included surgeons, physiotherapists and nurses, educated at Bachelor, Masters and Doctoral level. Consent to participate and demographic information were collected in advance of the interviews. In-depth, virtual semi-structured interviews were informed by a topic guide based on current evidence. Interviews of approximately 45 minutes were audio and video recorded and transcribed verbatim alongside written field notes. Data were coded and analysed using inductive thematic analysis, involving researchers with topic and methodological expertise and input from a patient representative.

RESULTS

Two themes emerged regarding current practice of using PROMs routine practice and personal evaluations. Four themes emerged as barriers to using PROMs for individuals with AIS: priority and support (e.g., HCPs focus on providing care), practical challenges (e.g., inadequate PROMs), patient-related challenges (e.g., patient preferences) and knowledge, education, and perceived value. Two themes emerged as facilitators: quality existing measure (e.g., sufficient psychometric properties), and priority and support (e.g., research department/culture). Themes for barriers to use performance measures were practicality (e.g., need physical space) and perceived value and knowledge (e.g., PROMs are more important), while the one theme for facilitators was practical consideration (e.g., acceptability).

CONCLUSIONS

Although HCPs perceived the value of using outcome measures, current practice indicates limited use for individuals with AIS. The findings revealed different barriers and facilitators to implement PROMs in practice. Adopting performance measure are limited due to lack of knowledge and perceived value alongside the practicality, while considering practical factors can improve the use of these measures in practice.

A single bout of prior resistance exercise attenuates muscle atrophy and declines in myofibrillar protein synthesis during bed-rest in older men

Impairments in myofibrillar protein synthesis (MyoPS) during bed rest accelerate skeletal muscle loss in older adults, increasing the risk of adverse secondary health outcomes. We investigated the effect of prior resistance exercise (RE) on MyoPS and muscle morphology during a disuse event in 10 healthy older men (65-80 years). Participants completed a single bout of unilateral leg RE the evening prior to 5 days of in-patient bed-rest. Quadriceps cross-sectional area (CSA) was determined prior to and following bed-rest. Serial muscle biopsies and dual stable isotope tracers were used to determine rates of integrated MyoPS (iMyoPS) over a 7 day habitual 'free-living' phase and the bed-rest phase, and rates of acute postabsorptive and postprandial MyoPS (aMyoPS) at the end of bed rest. Quadriceps CSA at 40%, 60% and 80% of muscle length significantly decreased in exercised (EX) and non-exercised control (CTL) legs with bed-rest. The decline in quadriceps CSA at 40% and 60% of muscle length was attenuated in EX compared with CTL. During bed-rest, iMyoPS rates decreased from habitual values in CTL, but not EX, and were significantly different between legs. Postprandial aMyoPS rates increased above postabsorptive values in EX only. The change in iMyoPS over bed-rest correlated with the change in quadriceps CSA in CTL, but not EX. A single bout of RE attenuated the decline in iMyoPS rates and quadriceps atrophy with 5 days of bed-rest in older men. Further work is required to understand the functional and clinical implications of prior RE in older patient populations. KEY POINTS: Age-related skeletal muscle deterioration, linked to numerous adverse health outcomes, is driven by impairments in muscle protein synthesis that are accelerated during periods of disuse. Resistance exercise can stimulate muscle protein synthesis over several days of recovery and therefore could counteract impairments in this process that occur in the early phase of disuse. In the present study, we demonstrate that the decline in myofibrillar protein synthesis and muscle atrophy over 5 days of bed-rest in older men was attenuated by a single bout of unilateral resistance exercise performed the evening prior to bed-rest. These findings suggest that concise resistance exercise intervention holds the potential to support muscle mass retention in older individuals during short-term disuse, with implications for delaying sarcopenia progression in ageing populations.

Predictors of poor outcome following lumbar spinal fusion surgery: a prospective observational study to derive two clinical prediction rules using British Spine Registry data

PURPOSE

Lumbar spinal fusion surgery (LSFS) is common for lumbar degenerative disorders. The objective was to develop clinical prediction rules to identify which patients are likely to have a favourable outcome to inform decisions regarding surgery and rehabilitation.

METHODS

A prospective observational study recruited 600 (derivation) and 600 (internal validation) consecutive adult patients undergoing LSFS for degenerative lumbar disorder through the British Spine Registry. Definition of good outcome (6 weeks, 12 months) was reduction in pain intensity (Numerical Rating Scale, 0-10) and disability (Oswestry Disability Index, ODI 0-50) > 1.7 and 14.3, respectively. Linear and logistic regression models were fitted and regression coefficients, Odds ratios and 95% CIs reported.

RESULTS

Lower BMI, higher ODI and higher leg pain pre-operatively were predictive of good disability outcome, higher back pain was predictive of good back pain outcome, and no previous surgery and higher leg pain were predictive of good leg pain outcome; all at 6 weeks. Working and higher leg pain were predictive of good ODI and leg pain outcomes, higher back pain was predictive of good back pain outcome, and higher leg pain was predictive of good leg pain outcome at 12 months. Model performance demonstrated reasonable to good calibration and adequate/very good discrimination.

CONCLUSIONS

BMI, ODI, leg and back pain and previous surgery are important considerations pre-operatively to inform decisions for surgery. Pre-operative leg and back pain and work status are important considerations to inform decisions for management following surgery. Findings may inform clinical decision making regarding LSFS and associated rehabilitation.

Predictors of Relevant Changes in Pain and Function for Adolescents with Idiopathic Scoliosis following Surgery

STUDY DESIGN

Retrospective analysis of longitudinal data.

OBJECTIVE

To evaluate clinically relevant change in surgical outcomes for Adolescents with Idiopathic Scoliosis (AIS), comparing those who achieved smallest detectable change (SDC) in pain and function at 1-year post-surgery and those who did not, and to evaluate the influencing factors.

SUMMARY OF BACKGROUND DATA

The SDC is recommended to evaluate the surgical outcomes of AIS. However, little is known about the use of SDC in AIS and its influencing factors.

METHODS

This was a retrospective analysis of longitudinal data from patients who underwent surgical correction at a tertiary spinal centre from to 2009-2019. Surgical outcomes were assessed at short-term (6 wk, 6 mo) and long-term (1- and 2-years) post-surgery using the Scoliosis Research Society (SRS-22r). The difference between 'successful' (≥ SDC) and 'unsuccessful' (< SDC) groups was assessed using an independent t-test. Univariate and logistic regression analyses enabled the assessment of influencing factors.

RESULTS

All SRS-22r domains decreased in the short term, except for self-image and satisfaction. In the long term, self-image increased by 1.21 and function increased by 0.2, and pain decreased by 0.1. In all SRS-22r domains 'successful' group had low pre-surgery scores and were statistically different to the 'unsuccessful group'. The difference remained statistically significant at 1-year for most SRS-22r domains. Being older and having low pre-surgery SRS-22r scores increased the chances of achieving SDC function at 1-year. Achieving SDC in the pain domain was significantly associated with age, sex, length of hospital stay, and pre-surgical scores.

CONCLUSION

Notably, the self-image domain showed the largest change compared to other SRS-22r domains. A low preoperative score increases the likelihood of clinical benefit from surgery. These findings demonstrate the utility of SDC for assessing the benefits and factors that may underpin surgical benefit in AIS.

Content validity of the Scoliosis Research Society questionnaire (SRS-22r): A qualitative concept elicitation study

INTRODUCTION

Scoliosis Research Society-22 revised (SRS-22r) is the common questionnaire used to evaluate health related quality of life (HRQOL) for young people with adolescent idiopathic scoliosis (AIS). The aim of this study is to evaluate its content validity for this population.

METHODS

In-depth semi-structured interviews were conducted with a purposive sample of young people with AIS (Cobb angle ≥25˚, aged 10-18 years). Concept elicitation was used to evaluate the influence of AIS on participants' HRQOL. Participant information sheets and consent/assent forms were age relevant. Topic guide was informed by the SRS-22r and existing evidence. Interviews were audio and video recorded, transcribed verbatim, coded, and analysed using thematic analysis. Derived themes/codes were compared with SRS-22r contents (domains/items).

RESULTS

Eleven participants (mean age 14.9 years [SD = 1.8]; 8 female) were recruited. The mean curve size was 47.5° [SD = 18°] and participants had been managed via different approaches. Four main themes emerged with associated subthemes: 1) Physical effects related to physical symptoms (back hurt, stiffness) and body asymmetry (uneven shoulders), 2) Activity-related effects showed impact on mobility (sitting for long periods), self-care (dressing), and school activities (focus during lessons), 3) Psychological effects revealed emotional (feel worried), mental (sleep quality), and body image effects (hide back from others), 4) Social effects (participation in school and leisure activities), and school, friends and mental health support. A weak association was found between items of the SRS-22r and the identified codes.

CONCLUSION

The SRS-22r does not adequately capture important concepts that relate to HRQOL of adolescents with AIS. These findings support revision of the SRS-22r, or the development of a new patient reported outcome measure to evaluate HRQOL of adolescents with AIS.

Evaluating measures of quality of life in adult scoliosis: a systematic review and narrative synthesis

PURPOSE

To systematically review and synthesise the evidence on the measurement properties of patient-reported outcome measure (PROMs) used to assess the quality of life in patients with adult scoliosis.

METHOD

Based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and a published protocol, a two-stage search was conducted and reported in line with the Preferred Reporting Items for Systematic review and Meta-analysis (PRISMA). Stage one identified all studies of patients with adult scoliosis which included PROMs of health-related quality of life (HR-QOL). Databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and Pubmed were searched from inception until 31st December 2020. This derived list of PROMs, was then utilised for a stage 2 search to identify studies which evaluated the measurement properties of the PROMs. Two reviewers independently performed the searches, study screening, selection and risk of bias assessment using the COSMIN tool. The overall quality of the evidence was assessed using a modified Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

Stage one yielded 16 PROMs of HR-QOL with the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 (SRS-22) the most used. Stage two identified three stage one PROMs that fulfilled eligibility criteria: SRS-22, ODI and SRS-22r; with five studies investigating measurement properties in an adult scoliosis population. The SRS-22 was the most comprehensively evaluated PROM in this cohort with very low-quality evidence indicating indeterminate reliability, sufficient construct validity and sufficient responsiveness of the SRS-22. There is very low-quality evidence indicating sufficient responsiveness of the ODI. There is very low-quality evidence indicating indeterminate cross-cultural validity for the SRS-22r. All other measurement properties in the SRS-22, ODI and SRS-22r have not been evaluated.

CONCLUSION

A large number of PROMs are being utilised in the adult scoliosis population and of these, the most commonly utilised are the ODI and SRS-22. The SRS-22, ODI and SRS-22r are the only PROMs to have had their measurement properties evaluated in the adult scoliosis population. The findings of this systematic review are that there currently is not sufficient evidence on the measurement properties of any PROMs in adult scoliosis. Further research is now urgently required to assess the measurement properties of these PROMs.

Individuals' beliefs about the biopsychosocial factors that contribute to their chronic musculoskeletal pain: protocol for a qualitative study in the UK

INTRODUCTION

Chronic musculoskeletal pain (CMP) is described as pain that persists for longer than 3 months. At present, no research is available that understands why CMP develops and continues from the perspective of the individual. Research is needed to establish if there are any consistent biopsychosocial factors perceived as contributing to CMP and what informs such beliefs. Understanding individual beliefs will inform more effective communication between clinicians and patients about their CMP, as well as informing future research into the epidemiology of CMP. Interpretative phenomenological analysis will be used as a methodological framework as it explores how individuals make sense of their world through personal experiences and perceptions while preserving individual nuance. The aim of this study is to understand individuals' beliefs and perceptions about the biological, psychological and social factors, which contribute to the development and maintenance of their CMP.

METHODS AND ANALYSIS

A qualitative study informed by the Consolidated Criteria for Reporting Qualitative Research using interpretative phenomenological analysis and semistructured interviews. A maximum variation purposive sample of 6-12 adults with CMP will be recruited from the general public in the UK. One semistructured interview will be conducted with each participant via an online video platform with interviews transcribed verbatim. The interview schedule (codesigned with expert patients and informed by existing evidence) identifies three domains of important questions; (1) patient beliefs on why they developed and continue to experience CMP; (2) the relationship between their biopsychosocial experiences and CMP; and (3) the origin of their beliefs. Strategies such as 'member checking' will be employed to ensure trustworthiness.

ETHICS AND DISSEMINATION

Ethical approval was granted by the Research Ethics Office at the University of Birmingham (reference ERN_21-0813). Informed consent will be obtained from all participants. The study findings will be submitted for publication in a peer-reviewed journal and for presentation at conferences.

Effectiveness of interventions for middle-aged and ageing population with neck pain: a systematic review and network meta-analysis protocol

INTRODUCTION

Neck pain (NP) is a common musculoskeletal complaint and is increasing in prevalence. Current clinical practice guidelines and systematic reviews recommended conservative, pharmacological and invasive interventions for individuals with NP. However, optimal management specifically for those who are middle-aged or older adults (≥45 years) is not available; and important considering our ageing population.

METHODS AND ANALYSIS

A systematic review with network meta-analysis (NMA) will be conducted following the Cochrane guidelines. Eligibility criteria include randomised controlled/clinical trials evaluating any of acute (<3 months) or chronic (≥3 months) non-specific NP, whiplash associated disorders, cervical radiculopathy and cervicogenic headache. Any interventions and outcome measures detailed within The International Classification of Functioning, Disability and Health domains will be included. Two independent reviewers will search key databases (AMED, CENTRAL, CINAHL, Embase, MEDLINE, PEDro and PsycINFO), grey literature, key journals and reference lists in May 2022. Two reviewers will decide eligibility and assess risk of bias (ROB) of included studies. The kappa statistic will be used to evaluate agreement between the reviewers at each stage. Data will be extracted by one reviewer and checked for accuracy by a second reviewer. Descriptive data and ROB will be summarised and tabulated. Traditional pairwise meta-analysis using random-effect model will be performed for all direct comparisons, and NMA using a frequentist random-effect model then performed based on NP classification where possible. A network of traditional pairwise meta-analysis allows comparisons of multiple interventions from both direct and indirect evidence to provide a hierarchal establishment for enhancing decision making of clinical practitioners.

ETHICS AND DISSEMINATION

Ethic approval is not required as the study is a literature review. The findings will be shared with the national and international researchers, healthcare professionals and the general public through publishing in a peer-reviewed journal and presentations at conferences.

Physical functioning outcome measures in the lumbar spinal surgery population and measurement properties of the physical outcome measures: protocol for a systematic review

INTRODUCTION

Low back pain can lead to substantial decline in physical functioning. For disabling pain not responsive to conservative management, surgical intervention can enhance physical functioning. Measurements of physical functioning include patient-reported outcome measures and physical outcome measures using evaluations of impairments, performance on a standardised task or activity in a natural environment. Selecting outcome measures with adequate measurement properties is fundamental to evaluating effectiveness of interventions. The purpose of this systematic review is to identify outcome measures (patient reported and physical) used to evaluate physical functioning (stage 1) and assess the measurement properties of physical outcome measures of physical functioning (stage 2) in the lumbar spinal surgery population.

METHODS AND ANALYSIS

This protocol aligns with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Using a two-staged approach, searches will be performed in MEDLINE, EMBASE, Health and Psychosocial Instruments, CINAHL, Web of Science, Scopus, PEDro and the grey literature from inception until 15 December 2021. Stage 1 will identify studies evaluating physical functioning with patient-reported or physical outcome measures in the lumbar spinal surgery population. Stage 2 will search for studies evaluating measurement properties (validity, reliability, responsiveness) of the physical outcome measures identified in stage 1 in the lumbar spinal surgery population. Two independent reviewers will evaluate studies for inclusion, extract data, assess risk of bias (COSMIN risk of bias tool and checklist) and quality of evidence (modified Grading of Recommendations Assessment, Development and Evaluation approach). Results for each measurement property per physical outcome measure will be quantitatively pooled if there is adequate clinical and methodological homogeneity or qualitatively synthesised if there is high heterogeneity in studies.

ETHICS AND DISSEMINATION

Ethics approval is not required. Results will be disseminated through peer-reviewed journal publication and conference presentation.

How is recovery defined and measured in patients with low back pain? Protocol for a mixed study systematic review

INTRODUCTION

This protocol describes the methods for a mixed study systematic review aiming to explore the definitions and measurements of recovery in patients with low back pain, and how perspectives of recovery differ between patients and providers. This review will be the first to review the concept of recovery in patients with low back pain across both quantitative and qualitative literature.

METHODS AND ANALYSIS

This protocol has been designed and reported in line with Preferred Reporting Items of Systematic Reviews and Meta-Analyses Protocols. The following databases will be electronically searched from database inception until 30 November 2021: Medline, EMBASE, CINAHL, Cochrane, PEDro. Grey literature will be searched for through targeted searching of ProQuest Dissertations and Theses and handsearching of the references of all included studies. Studies will be included if they include a patient population of >50% with low back pain (with or without leg pain), and mention the concept of recovery within the abstract, methods or results. The Mixed Methods Appraisal Tool will be used for quality assessment of both quantitative and qualitative included studies. Two independent reviewers will conduct the search, screen titles/abstracts and extract relevant data from full texts. Discrepancies between reviewers will be settled by a third reviewer with spinal pain expertise. For syntheses, thematic analysis will be used to analyse both qualitative and quantitative investigations to explore meanings, measurement and perspectives of recovery from a diverse evidence base. There is no clinical trial associated with this protocol.

ETHICS AND DISSEMINATION

There are no ethical issues associated with this systematic review, and ethics approval was not required. Once completed, the results of this review will be published in a peer-reviewed journal within the realm of spinal pain to help guide future research inquiries.

Development of a clinical prediction model to inform clinical decision making for classification of patients with sciatica, based on their clinical characteristics, in the Greek health system: protocol for a prospective predictive exploratory study

INTRODUCTION

Sciatica is one of the most common reasons for seeking healthcare for musculoskeletal pain. Sciatica is primarily considered as neuropathic in nature when neural tissue in the low back is compromised, but sometimes other non-neural structures may be involved. Appropriate assessment and management are important for patients with sciatica. Therapists use several outcome measures to assess patients to inform selection of the most suitable treatment. There is limited evidence for the best treatment of sciatica, and this is likely contributed to by having no reliable algorithm to categorise patients based on their clinical characteristics to inform physiotherapy treatment. The purpose of this study is to develop a clinical prediction model to categorise patients with sciatica, in terms of early clinical outcome, based on their initial clinical characteristics.

METHODS AND ANALYSIS

A prospective observational multicentre design will recruit consecutive patients (n=467) with sciatica referred for physiotherapy. Each patient will be evaluated to determine whether or not they will be accepted into the study by answering some questions that will confirm the study's eligibility criteria. Patients' basic characteristics, patient-reported outcome measures and performance-based measures will be collected at baseline from multiple sites in the Greek territory using this same protocol, prior to commencement of treatment. The main researcher of this study will be responsible for data collection in all sites. On completion of the standard referred physiotherapy treatment after 3 weeks' time, participants will be asked by telephone to evaluate their outcome using the Global Perceived Effect Scale. For the descriptive statistical analysis, the continuous variables will be expressed in the form of 'mean' and 'SD'. In order to assess the prognostic value of each predictor, in terms of the level of improvement or worsening of the symptoms, multiple variable regression analysis will be used.

ETHICS AND DISSEMINATION

Τhis study is approved from the Ethics and Deontology Committee of the University of West Attica, Athens, Greece, protocol number: 38313-09/06/2020, 10226-10/02/2021. The study's findings will be published in a peer-reviewed journal and disseminated at national and international conferences and through social media.

Content validity of Scoliosis Research Society questionnaire-22 revised (SRS-22r) for adolescents with idiopathic scoliosis: protocol for a qualitative study exploring patient's and practitioner's perspectives

INTRODUCTION

Content validity is the most important measurement property for any patient-reported outcome measure (PROM). It being the extent that the PROM measures important concepts that are relevant to the population of interest. Adolescent with idiopathic scoliosis (AIS) is the most common spinal deformity in paediatric populations, with the Scoliosis Research Society questionnaire-22 revised (SRS-22r) a commonly used PROMof quality of life. In the absence of existing evidence, a content validity study for SRS-22r is needed to confirm its suitability for AIS. Thus, this study aims to investigate the content validity of SRS-22r for AIS. A secondary aim is to explore healthcare professional (HCP) perspectives of the barriers and facilitators to using outcome measures in AIS.

METHODS AND ANALYSIS

Qualitative study reported according to COnsolidated criteria for Reporting Qualitative Studies. A purposive sample of AIS (n=10-15, Cobb angle >25°, aged 10-18 years) will be recruited for online semi-structured interviews. A convenience sample (n=10-12) of HCP with clinical and/or research experience in AIS will be recruited for a focus group discussion. Topic guides and age-relevant documents are informed by existing evidence and developed using a framework of concept elicitation and cognitive debriefing. Audio-recordings will be transcribed verbatim, coded, analysed and synthesised using interpretive phenomenology analysis. Themes that generated from the analysis will be used as codes that will then be mapped to the SRS-22r contents.

ETHICS AND DISSEMINATION

The Health Research Authority and Health and Care Research Wales approval have been granted (IRAS 289888). Study findings will be disseminated through publications in peer-reviewed journals and conference presentations.

Which biopsychosocial factors are associated with the development of chronic musculoskeletal pain? Protocol for an umbrella review of systematic reviews

INTRODUCTION

Recent systematic reviews have identified many biopsychosocial factors associated with the development of chronic musculoskeletal pain (CMP). Despite often being specific to a particular musculoskeletal condition, findings are similar across systematic reviews. Research is needed to aggregate these findings to identify consistent factors across musculoskeletal disorders that are associated with the development of CMP. The objective of this study is to provide a meta-level synthesis of all biopsychosocial factors associated with the development of CMP.

METHODS AND ANALYSIS

An umbrella review and meta-level narrative synthesis±meta-analysis has been designed informed by Joanna Briggs Institute and Cochrane guidance. This protocol is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis-P. Sources will include Ovid Medline, Embase, Web of Science Core Collection, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, PsycINFO, CINAHL, PEDro, PROSPERO, Google Scholar and grey literature.

INCLUSION CRITERIA

any systematic review which investigates biopsychosocial factors which may be associated with the development of CMP through prospective longitudinal methods. The outcome is musculoskeletal pain lasting beyond 3 months. Two independent reviewers will be involved in all stages; screening, selection, data extraction and risk of bias evaluation using the Assessing the Methodological Quality of Systematic Reviews-2 guidelines. A meta-level narrative synthesis will be conducted based on (a) factors associated with development of CMP, (b) the range of musculoskeletal disorders for which the same/similar findings have been established and (c) the quality of studies informing these findings. Where possible, meta-analysis will be performed. The Grading of Recommendations, Assessment, Development and Evaluation guidelines will be followed to determine the level of evidence for each biopsychosocial factor.

ETHICS AND DISSEMINATION

This umbrella review does not require ethical approval. Findings will be presented at conferences and published in a peer reviewed journal.

Evaluating measures of quality of life in adult scoliosis: a protocol for a systematic review and narrative synthesis

BACKGROUND

Adult scoliosis represents a distinct subgroup of scoliosis patients for whom the diagnosis can have a large impact on their health-related quality of life (HR-QOL). Therefore, HR-QOL patient-reported outcome measures (PROMs) are essential to assess disease progression and the impact of interventions. The objective of this systematic review is to evaluate the measurement properties of HR-QOL PROMs in adult scoliosis patients.

METHODS

We will conduct a literature search, from their inception onwards, of multiple electronic databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and PubMed. The searches will be performed in two stages. For both stages of the search, participants will be aged 18 and over with a diagnosis of scoliosis. The primary outcome of interest in the stage one searches will be studies which use PROMs to investigate HR-QOL as defined by the Core Outcome Measures in Effectiveness Trials (COMET) taxonomy, the secondary outcome will be to assess the frequency of use of the various PROMs. In stage two, the primary outcome of interest will be studies which assess the measurement properties of the HR-QOL PROMs identified in stage one. No specific measurement property will be given priority. No planned secondary outcomes have been identified but will be reported if discovered. In stage one, the only restriction on study design will be the exclusion of systematic reviews. In Stage two the only restriction on study design will be the exclusion of full-text articles not available in the English language. Two reviewers will independently screen all citations and abstract data. Potential conflicts will be resolved through discussion. The study methodological quality (or risk of bias) will be appraised using the Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) checklist. The overall strength of the body of evidence will then be assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. A narrative synthesis will be provided with information presented in the main text and tables to summarise and explain the characteristics and findings of the included studies. The narrative synthesis will explore the evidence for currently used PROMs in adult scoliosis patients and any areas that require further study.

DISCUSSION

The review will help clinicians and researchers identify a HR-QOL PROM for use in patients with adult scoliosis. Findings from the review will be published and disseminated through a peer-reviewed journal and conference presentations.

SYSTEMATIC REVIEW REGISTRATION

This systematic review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO), reference number: CRD42020219437.

Outcomes evaluating quality of life and their measurement properties in early-onset scoliosis: protocol for a systematic review

INTRODUCTION

Early-onset scoliosis (EOS) is a rare spinal deformity affecting children under the age of 10. Both the condition and its treatment have associated morbidity and can impact quality of life. Understanding this impact can be achieved by using appropriate patient-reported and/or carer-reported outcome measures. The aim of the review described in this protocol is to evaluate the evidence on measurement properties relevant to health-related quality of life outcomes in the EOS population. The focus will be on outcome measures relevant to patients undergoing treatment of EOS under the age of 10.

METHODS/ANALYSIS

This protocol is reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol and COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology. The MEDLINE, EMBASE, EMCARE, PubMed, PsychINFO and CINAHL databases will be searched using a two-stage search strategy. The first stage will identify measures of HRQoL used in EOS through screening of titles and abstracts. The second stage will assess the measurement properties of those measures identified through screening of full-text articles. The measurement properties of interest are the 'reliability', 'validity' and 'responsiveness' of the instrument. Only English language articles will be considered. Two reviewers will independently review the search results against the eligibility criteria, perform data extraction and assess for risk of bias, with disputes handled by a third reviewer. Data will be quantitatively pooled where possible or reported as a narrative synthesis. The summarised results for each measurement property will be rated against the criteria for good measurement properties following the COSMIN methodology. Two reviewers will assess the body of evidence for each measurement property using modified Grading of Recommendations, Assessment, Development and Evaluation guidelines.

ETHICS AND DISSEMINATION

No ethical approval is required for this review and the results will be submitted for publication in peer-reviewed publications.

The experiences and perceived health benefits of individuals with a disability participating in sport: A systematic review and narrative synthesis

BACKGROUND

Sports participation has many physical and mental health benefits for individuals with a disability including improved functionality and reduced anxiety, yet a large proportion of individuals with a disability are inactive.

OBJECTIVE

To investigate the experiences and perceived health benefits of sport participation across four disability populations: children and adolescents, adults, elite athletes and veterans with a disability.

METHODS

A mixed-methods systematic review was conducted. Eligible studies had participants who were children, adults, elite athletes or veterans with a physical, visual or intellectual disability. Data were extracted using the Joanna Briggs Institute (JBI) tool and quality assessment involved the Quality Assessment Tool for Studies with Diverse Designs (QATSDD). Content, thematic and narrative synthesis techniques were used. Confidence in cumulative evidence was determined using GRADE-CERQual and Classes of Evidence.

RESULTS

Several positive aspects of sport participation were highlighted across all four populations, including socialisation opportunities, pure enjoyment, a sense of freedom and providing an arena to challenge stereotypes. The paucity of research within the 'veterans with a disability' group limited analysis of experiences and benefits of sport in this population.

CONCLUSIONS

This systematic review was the first to explore this phenomena, finding that overall sport is a beneficial experience for individuals with a disability. The positive aspects should be promoted when encouraging sport participation for children, adolescents, adults and elite athletes. More research is needed to explore these phenomena in veterans and to compare perceived benefits between populations to enable tailored promotion of sport.

The podium illusion: a phenomenological study of the influence of social support on well-being and performance in elite para swimmers

Background

The value of social support in enhancing performance is well established in non-impaired and sub-international level athletes with impairments. Despite this, no research to date has explored the experiences of social support in elite para-athletes. The aim of this study was to explore the experiences of social support in elite British para-swimmers and the influence on their wellbeing and performance.

Methods

A hermeneutic phenomenological study involving semi-structured interviews was undertaken with 8 elite British para-swimmers (3 male, 5 female, mean age 24.9 years). Participants represented 5 para-swimming classes and all 10 of the International Paralympic Committee impairment categories. Data were analysed following a modified version of the Framework Method. Research quality and trustworthiness were ensured through employing techniques including data triangulation, member checking and reflexivity.

Results

Five themes and 11 sub-themes were generated. The five themes were: ‘the coach-athlete relationship’, ‘team bond’, ‘tangible aid’, ‘The Podium Illusion’ and ‘British para-swimming’. The overall findings and the magnitude of support mentioned in the fourth theme led to the development of a new model called ‘The Podium Illusion’ which reflects the magnitude of support that is available to elite para-swimmers to help maximise their performance and wellbeing.

Conclusion

Social support is essential for athlete wellbeing and performance. Findings underpin a new model, ‘The Podium Illusion’.

Successful recovery following musculoskeletal trauma: protocol for a qualitative study of patients' and physiotherapists' perceptions

Background

Annually in the UK, 40,000–90,000 people are involved in a traumatic incident. Severity of injury and how well people recover from their injuries varies, with physiotherapy playing a key role in the rehabilitation process. Recovery is evaluated using multiple outcome measures for perceived levels of pain severity and quality of life. It is unclear however, what constitutes a successful recovery from injury throughout the course of recovery from the patient perspective, and whether this aligns with physiotherapists’ perspectives.

Methods

A qualitative study using two approaches: Interpretive Phenomenological Analysis (IPA) using semi-structured interviews and thematic analysis following the Kreuger framework for focus groups. A purposive sample of 20 patients who have experienced musculoskeletal trauma within the past 4 weeks and 12 physiotherapists who manage this patient population will be recruited from a single trauma centre in the UK. Semi-structured interviews with patients at 4 weeks, 6 and 12 months following injury, and 2 focus groups with physiotherapists will be undertaken at one time point. Views and perceptions on the definition of recovery and what constitutes a successful recovery will be explored using both methods, with a focus on the lived experience and patient journey following musculoskeletal trauma, and how this changes through the process of recovery. Data from both the semi-structured interviews and focus groups will be analysed separately and then integrated and synthesised into key themes ensuring similarities and differences are identified. Strategies to ensure trustworthiness e.g., reflexivity will be employed.

Discussion

Recovery following musculoskeletal trauma is complex and understanding of the concept of successful recovery and how this changes over time following an injury is largely unknown. It is imperative to understand the patient perspective and whether these perceptions align with current views of physiotherapists. A greater understanding of recovery following musculoskeletal trauma has potential to change clinical care, optimise patient centred care and improve efficiency and clinical decision making during rehabilitation. This in turn can contribute to improved clinical effectiveness, patient outcome and patient satisfaction with potential service and economic cost savings. This study has ethical approval (IRAS 287781/REC 20/PR/0712).

Experiences of telehealth e-mentoring within postgraduate musculoskeletal physical therapy education in the UK and Canada: a protocol for parallel mixed-methods studies and cross-cultural comparison

INTRODUCTION

Mentored clinical practice is central to demonstrating achievement of International Educational Standards in advanced musculoskeletal physical therapy. While traditionally delivered face-to-face, telehealth e-mentoring is a novel alternative to offering this unique pedagogy to facilitate mentee critical reflection, deeper learning and enhanced knowledge translation to optimise patient care. With COVID-19 resulting in widespread adoption of telehealth and access to mentors often limited by geography or cost, the potential value of telehealth e-mentoring needs investigating. To investigate the experiences and outcomes of multiple stakeholders (student mentees, mentors and patients) engaged in musculoskeletal physical therapy telehealth e-mentoring across two universities (UK and Canada).

METHODS AND ANALYSIS

Using case study design, we will use sequential mixed methods involving qualitative and quantitative components based on existing evidence. To examine the influence of telehealth e-mentoring on health outcomes in patients with musculoskeletal complaints, we will use patient-reported outcomes for satisfaction, patient empowerment and change in musculoskeletal health. We will conduct semistructured interviews to explore the development of critical thinking, clinical reasoning, communication skills and confidence of students engaged in telehealth e-mentoring. To explore the mentor acceptability and appropriateness of telehealth e-mentoring, we will conduct a focus group in each site. Finally, we will include a focus group of participants from each site to allow a cross-cultural comparison of findings to inform international stakeholders. Quantitative data will be analysed using descriptive statistics (median and IQR) to describe changes in outcome data and qualitative data will be analysed following the Framework Method.

ETHICS AND DISSEMINATION

This study has ethical approval from both institutions: the University of Birmingham (ERN_20-0695) and Western University (2020-116233-47832). Findings will be published in a peer-reviewed journal and disseminated to key stakeholders in musculoskeletal physical therapy education and practice.

The effect of short-term exercise prehabilitation on skeletal muscle protein synthesis and atrophy during bed rest in older men

BACKGROUND

Poor recovery from periods of disuse accelerates age-related muscle loss, predisposing individuals to the development of secondary adverse health outcomes. Exercise prior to disuse (prehabilitation) may prevent muscle deterioration during subsequent unloading. The present study aimed to investigate the effect of short-term resistance exercise training (RET) prehabilitation on muscle morphology and regulatory mechanisms during 5 days of bed rest in older men.

METHODS

Ten healthy older men aged 65-80 years underwent four bouts of high-volume unilateral leg RET over 7 days prior to 5 days of inpatient bed rest. Physical activity and step-count were monitored over the course of RET prehabilitation and bed rest, whilst dietary intake was recorded throughout. Prior to and following bed rest, quadriceps cross-sectional area (CSA), and hormone/lipid profiles were determined. Serial muscle biopsies and dual-stable isotope tracers were used to determine integrated myofibrillar protein synthesis (iMyoPS) over RET prehabilitation and bed rest phases, and acute postabsorptive and postprandial myofibrillar protein synthesis (aMyoPS) rates at the end of bed rest.

RESULTS

During bed rest, daily step-count and light and moderate physical activity time decreased, whilst sedentary time increased when compared with habitual levels (P < 0.001 for all). Dietary protein and fibre intake during bed rest were lower than habitual values (P < 0.01 for both). iMyoPS rates were significantly greater in the exercised leg (EX) compared with the non-exercised control leg (CTL) over prehabilitation (1.76 ± 0.37%/day vs. 1.36 ± 0.18%/day, respectively; P = 0.007). iMyoPS rates decreased similarly in EX and CTL during bed rest (CTL, 1.07 ± 0.22%/day; EX, 1.30 ± 0.38%/day; P = 0.037 and 0.002, respectively). Postprandial aMyoPS rates increased above postabsorptive values in EX only (P = 0.018), with no difference in delta postprandial aMyoPS stimulation between legs. Quadriceps CSA at 40%, 60%, and 80% of muscle length decreased significantly in EX and CTL over bed rest (0.69%, 3.5%, and 2.8%, respectively; P < 0.01 for all), with no differences between legs. No differences in fibre-type CSA were observed between legs or with bed rest. Plasma insulin and serum lipids did not change with bed rest.

CONCLUSIONS

Short-term resistance exercise prehabilitation augmented iMyoPS rates in older men but did not offset the relative decline in iMyoPS and muscle mass during bed rest.

Clinical effectiveness of manipulation and mobilisation interventions for the treatment of non-specific neck pain: protocol for a systematic review and meta-analysis

INTRODUCTION

Non-specific neck pain (NSNP) is a common musculoskeletal condition resulting in pain, physical limitations and associated functional disability. Current guidelines recommend manipulation and/or mobilisation as part of the multimodal management of NSNP. This study focuses on intervention at the articular level and aims to identify whether joint mobilisation or joint manipulation has a greater effect on function, range of movement or pain outcomes in the management of NSNP.

METHODS AND ANALYSIS

A systematic review protocol has been designed and is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. A targeted search strategy will enable searching of key databases from inception to 31 March 2020: CINAHL, PEDro, AMED, EMBASE, OVID, MEDLINE, Web of Science, PubMed and Google Scholar. Key journals will be searched using predefined keywords determined from preliminary scoping searches for randomised controlled trials of manipulation and mobilisation modalities for adults with NSNP in the absence of radiculopathy or whiplash, published in English. Grey literature and unpublished studies will also be searched. Studies will be screened by title and abstract and full text. Two independent reviewers will conduct the searches independently, extract data, assess risk of bias (Cochrane Risk of Bias Tool 2) and assess overall strength of evidence (Grading of Recommendations, Assessment, Development and Evaluation). Meta-analysis will be performed where individual studies measure comparable outcomes including performance-based outcome measures such as range of movement or patient reported outcome measures such as Neck Disability Index; and where interventions are comparable in their delivery such as number of oscillations and Maitland grading. Where not possible, data will be presented descriptively.

ETHICS AND DISSEMINATION

This study does not require ethical approval. Findings will be submitted for publication to relevant peer-reviewed journals and will be presented at profession-specific conferences.

Measures of central sensitization and their measurement properties in musculoskeletal trauma: A systematic review

BACKGROUND AND OBJECTIVE

Chronic pain following musculoskeletal trauma is common, which may partially be attributed to the early presence of central sensitization (CS). Multiple measures are suggested to assess clinical features of CS, yet no systematic review has evaluated the measurement properties of these measures in a musculoskeletal trauma population.

DATABASES AND DATA TREATMENT

This systematic review, which followed a published and PROSPERO registered protocol (CRD42018091531), aimed to establish the scope of CS measures used within a musculoskeletal trauma population and evaluate their measurement properties. Searches were conducted in two stages by two independent reviewers. The Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) checklist was used to evaluate risk of bias and overall quality was assessed using the modified Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

From 86 studies, 30 different CS outcome measures were identified. Nine studies evaluated measurement properties of nine outcome measures; eight evaluated reliability and one evaluated construct validity. Measures included seven quantitative sensory testing methods (pressure, cold and electrical pain thresholds; warm, cold and vibration detection thresholds; vibration perception thresholds), pain drawings and a pinwheel. Risk of bias was assessed as doubtful/inadequate for all but one study, overall quality of evidence was low/very low for all measures. Reliability of measures ranged from poor to excellent.

CONCLUSIONS

Many measures are used to evaluate CS but with limited established measurement properties in musculoskeletal trauma. High quality research to establish measurement properties of CS outcome measures is required.

Physical prognostic factors predicting outcome following anterior cruciate ligament reconstruction: protocol for a systematic review

INTRODUCTION

Injuries of the anterior cruciate ligament (ACL) are a common musculoskeletal complication and can cause significant reduction in patient function and quality of life. Many undergo ACL reconstruction, with high-quality rehabilitation key to successful outcome. Knowledge of physical prognostic factors, such as quadriceps strength, is crucial to inform rehabilitation and has important implications for outcome following ACL reconstruction. However, these factors predicting outcome are poorly defined. Therefore, the aim of this systematic review is to establish physical prognostic factors predictive of outcome in adults following ACL reconstruction. Outcome will be subdivided into two groups of outcome measures, patient-reported and performance-based. Physical prognostic factors of interest will reflect a range of domains and may be modifiable/non-modifiable. Results will help decide most appropriate management and assist in planning and tailoring preoperative and postoperative rehabilitation.

METHODS AND ANALYSIS

This systematic review protocol is reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. MEDLINE, CINAHL and EMBASE databases, key journals and grey literature will be searched from inception to July 2019. Prospective cohort studies including participants aged ≥16 years who have undergone ACL reconstruction will be included, with articles focusing on multi-ligament reconstructions and ACL repair surgery, or not published in English excluded. Two independent reviewers will conduct searches, assess study eligibility, extract data, assess risk of bias (Quality in Prognostic Studies tool) and quantify overall quality of evidence (modified Grading of Recommendations, Assessment, Development and Evaluation guidelines). If possible, a meta-analysis will be conducted, otherwise a narrative synthesis will ensue focusing on prognostic factors, risk of bias of included studies and strength of association with outcomes.

ETHICS AND DISSEMINATION

Findings will be published in a peer-reviewed journal, presented at conferences and locally to physiotherapy departments. Ethical approval is not required for this systematic review.

Clinical indicators to identify neuropathic pain in low back-related leg pain: protocol for a modified Delphi study

INTRODUCTION

Neuropathic low back-related leg pain (LBLP) can be a challenge to healthcare providers to diagnose and treat. Accurate diagnosis of neuropathic pain is fundamental to ensure appropriate intervention is given. However, to date there is no gold standard to diagnose neuropathic LBLP. A Delphi study will therefore be conducted to obtain an expert-derived consensus list of clinical indicators to identify a neuropathic component to LBLP.

METHODS/ANALYSIS

Included participants will be considered experts within the field as measured against a predefined eligibility criterion. Through an iterative multistage process, participants will rate their agreement with a list of clinical indicators and suggest any missing clinical indicators during each round. Agreement will be measured using a 5-point Likert scale. Descriptive statistics will be used to measure agreement; median, IQR and percentage of agreement. A priori consensus criteria will be defined for each round. Data analysis at the end of round three will enable a list of clinical indicators to be derived.

ETHICS AND DISSEMINATION

Ethical approval was gained from the University of Birmingham (ERN_19-1142). On completion of the study, findings will be disseminated in a peer-reviewed journal and presented at relevant conferences.

Are neuromuscular adaptations present in people with recurrent spinal pain during a period of remission? A protocol for a systematic review

INTRODUCTION

The course of spinal pain (neck or low back pain) is often described as episodic and intermittent, with more than one-third of people continuing to experience episodic symptoms 1 year after first onset. Although ongoing neuromuscular adaptations could contribute to recurrent episodes of pain, no systematic review has synthesised evidence of ongoing neuromuscular changes in people with recurrent spinal pain during a period of symptom remission.

METHODS AND ANALYSIS

This protocol is developed and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-P, the Update of the Cochrane Back and Neck Group guidelines and the Methodological Expectations of Cochrane Intervention Reviews. PubMed, Web of Science, MEDLINE, EMBASE, CINAHL, ZETOC, Google Scholar, grey literature sources and key journals will be searched up to September 2019. Observational studies investigating neuromuscular changes in people with recurrent spinal pain during a period of remission will be included. Neuromuscular function will be considered under five outcome domains of muscle activity, spine kinematics, muscle properties, sensorimotor control and neuromuscular performance. Two independent reviewers will search, screen studies, extract data and assess risk of bias (Newcastle-Ottawa Scale). Data will be synthesised per outcome domain. Where clinical and methodological homogeneity across studies exists, a random-effects meta-analysis will be conducted. Otherwise, results will be synthesised narratively. The overall quality of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation guidelines.

ETHICS AND DISSEMINATION

Findings of this review may aid the identification of factors that could contribute to spinal pain recurrence and aid the development of interventions for secondary prevention aimed at the restoration of optimal neuromuscular function. The results will be submitted for publication in a peer-reviewed journal and presented at conferences. No ethical approval was required.

Effectiveness of prehabilitation for patients undergoing orthopaedic surgery: protocol for a systematic review and meta-analysis

INTRODUCTION

Undergoing major surgery can induce physical and functional decline. Prehabilitation programmes aim to improve physical fitness and function preoperatively and could enhance postoperative recovery and outcomes. Prehabilitation interventions have been utilised across a range of orthopaedic populations of all ages and can be multimodal in nature. The aim of this study is to evaluate the effectiveness of prehabilitation for patients undergoing orthopaedic surgery including day surgery procedures. It will also investigate the components of prehabilitation to understand optimum duration and frequency of programmes.

METHODS/DESIGN

Systematic review and meta-analysis designed in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. A comprehensive electronic search will be performed in MEDLINE, CINAHL, AMED, Embase, PEDro and Cochrane CENTRAL databases in order to identify randomised control trials published between January 2000 to 25 March 2019. ISI Web of Science, System for information on grey literature and the European Union clinical trials registry will identify studies that are underway or unpublished. Two independent reviewers will carry out the searches, study selection (title and abstract and full text stages), data extraction, risk of bias assessment (Cochrane Risk of Bias tool 2.0) and evaluation of overall strength of evidence. Meta-analyses will be used for data which demonstrates homogeneity, otherwise a narrative synthesis will be performed for groups of studies of high heterogeneity (I² >50%). The overall strength of the body of evidence will be assessed using Grading of Recommendations Assessment, Development and Evaluation.

ETHICS AND DISSEMINATION

This study raises no ethical issues. This study aims to identify the effectiveness of prehabilitation interventions and may assist clinicians in determining which components, duration, frequency and the method of delivery would form the most effective prehabilitation intervention for patients undergoing an orthopaedic surgical procedure. The findings will be disseminated through publication in a peer-reviewed journal and conference presentations.

Predictors of pain reduction following manual therapy in patients with temporomandibular disorders: a protocol for a prospective observational study

INTRODUCTION

Temporomandibular disorders (TMDs) are principally characterised by pain in the craniomandibular area and probable limitations of jaw opening. Manual therapy, like other recommended conservative treatments included in clinical guidelines, is commonly used to treat patients with TMD to reduce pain and improve function. However, outcomes may be variable. The aim of this study is to identify predictors associated with pain reduction in patients with TMD following manual therapy by analysing a combination of patient-reported outcome measures and clinical tests. Such knowledge will support a more personalised management approach by facilitating clinical decision-making.

METHODS/ANALYSIS

An observational prospective design will recruit a cohort of 100 adults with a diagnosis of TMD (according to Axis I of the Diagnostic Criteria for TMD) at a Dental Hospital in Italy. Patients will be treated with four weekly sessions of manual therapy applied to craniomandibular structures. An array of predictors has been chosen based on previous research on prognostic factors for TMD and altered pain modulation in musculoskeletal disorders. Candidate predictors including demographic variables, general health variables, psychosocial features, TMD characteristics and clinical tests of the temporomandibular joint and masticatory muscles will be collected at baseline. Definition of good outcome is a clinically significant reduction of pain intensity over the last week (≥30% reduction Visual Analogue Scale) immediately following the four week intervention. Exploratory factor analysis will be applied to analyse factor loading of candidate predictors for good outcome at four weeks. Subsequently, a logistic multivariable regression model will be performed to calculate low and high risk of good outcome.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the 'Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico' and University of Birmingham Ethics Committee. The results will be submitted for publication in a peer-reviewed journal and presented at conferences.

The effect of chronic, non-specific low back pain on superficial lumbar muscle activity: a protocol for a systematic review and meta-analysis

INTRODUCTION

Chronic, non-specific low back pain is a major global cause of disability. One factor which might potentially contribute to ongoing pain is maladaptive variation in the level of activity in the lumbar musculature. Several studies have investigated this activity using surface electromyography, in varied muscles and during a number of functional activities. Due to differences in the applied methodology, the results have been difficult to compare, and previous reviews have been limited in scope. In this protocol, we aim to perform a comprehensive review of the effect of chronic low back pain on lumbar muscle activity.

METHODS AND ANALYSIS

This protocol was informed by the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) and results will be reported in line with the PRISMA. Searches will be conducted on the Web of Science, PubMed, MEDLINE, EMBASE, ZETOC and CINAHL databases, along with a comprehensive review of grey literature and key journals. One reviewer will conduct the searches, but two independent reviewers will screen potential studies and assess the risk of bias within studies which meet the inclusion criteria. The Newcastle-Ottawa risk of bias tool, and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines will be used to assess the quality of the data. Meta-analysis will be conducted where appropriate on groups of studies with homogenous methodology. Where studies are too heterogeneous to allow for meta-analysis, meta-synthesis will instead be completed, comparing results in terms of net increases or decreases of activity.

ETHICS AND DISSEMINATION

This review aims to identify common adaptations of muscle activity in people with low back pain and it is expected that the results will influence future research directions and future rehabilitation approaches. The results will be submitted for publication in a peer-reviewed journal and presented at conferences.

Pragmatic cluster randomised double-blind pilot and feasibility trial of an active behavioural physiotherapy intervention for acute non-specific neck pain: a mixed-methods protocol

INTRODUCTION

Non-specific neck pain causes pain and disability and contributes substantial socioeconomic burden internationally. Up to 50% of adults experience neck pain annually, leading to reduced the quality of life. An active behavioural physiotherapy intervention (ABPI) may be feasible to manage patients with acute non-specific neck pain to prevent transition to chronicity. A recent pilot and feasibility trial investigating an acute whiplash-associated disorder population found potential value of the ABPI with 95% of participants fully recovered (Neck Disability Index: NDI ≤4, compared with 17% in the standard physiotherapy arm); supporting a definitive trial. Qualitative findings from the physiotherapists supported the potential of the ABPI in a non-specific neck pain population.

METHODS AND ANALYSIS

Two phases: (1) Pragmatic cluster randomised double-blind, parallel 2-arm (ABPI vs standard physiotherapy intervention) pilot and feasibility trial to evaluate the procedures and feasibility of the ABPI for the management of acute non-specific neck pain. Six physiotherapy departments from six public hospitals in Thailand will be recruited and cluster randomised by a computer-generated randomisation sequence with block sampling. Sixty participants (30 each arm, 10 per hospital) will be assessed at baseline and 3 months following baseline for NDI, Numerical Rating Scale for pain intensity, cervical range of motion, fear-avoidance beliefs questionnaire and EuroQol-5 dimensions 5 levels outcomes, and (2) Embedded qualitative study using semistructured interviews to explore acceptability of the ABPI to participants (n=12) and physiotherapists (n=3). Descriptive analysis of the quantitative data and interpretative phenomenological analysis to code and analyse qualitative data (deductive and inductive) will inform feasibility for a future definitive trial.

Patient journey following lumbar discectomy surgery: protocol for a single-centre qualitative analysis of the patient rehabilitation experience (DiscJourn)

INTRODUCTION

Lumbar discectomy is a widely used surgical procedure internationally with the majority of patients experiencing significant benefit. However, approximately 20% of patients report suboptimal functional recovery and quality of life. The impact and meaning of the surgical experience from the patients' perspective are not fully understood. Furthermore, there is limited evidence guiding postoperative management with significant clinical practice variation and it is unclear if current postoperative support is valued, beneficial or meets patients' needs and expectations. This study aims to address the evidence gap by moving beyond current knowledge to gain insight into the lived experiences relating to patients' lumbar discectomy surgery journey. Results will inform more meaningful and specific care, thus, enhance rehabilitation and outcomes.

METHODS AND ANALYSIS

A qualitative investigation using interpretative phenomenology analysis (IPA) will provide a flexible inductive research approach. A purposive sample (n=20) of patients undergoing primary discectomy will be recruited from one UK NHS secondary care centre. Semi-structured interviews will be conducted postsurgery discharge. A topic guide, developed from the literature and our previous work with input from two patient co-investigators, will guide interviews with the flexibility to explore interesting or patient-specific points raised. Providing longitudinal data, patients will keep weekly diaries capturing experiences and change over time throughout 12 months following surgery. A second interview will be completed 1 year postsurgery with its topic guide informed by initial findings. This combination of patient interviews and diaries will capture patients' attitudes and beliefs regarding surgery and recovery, facilitators and barriers to progress, experiences regarding return to activities/function and interactions with healthcare professionals. The rich density of data will be thematically analysed in accordance with IPA, supported by NVivo software.

Ethical approval has been granted by the London-Bloomsbury Research Ethics Committee (18/LO/0459; IRAS 241345). Conclusions will be disseminated through conferences and peer-reviewed journals.

Perceptions of Australian physiotherapy students about the potential implementation of physiotherapist prescribing in Australia: a national survey

OBJECTIVES

To explore the perceptions of Australian physiotherapy students about (1) the potential implementation and use of non-medical prescribing by physiotherapists in Australia and (2) how physiotherapist prescribing might impact the care that the physiotherapy profession can provide in the future.

DESIGN

A cross-sectional descriptive survey of physiotherapy students across Australia was completed using an online questionnaire developed by subject-experts and pretested (n=10) for internal consistency. A hyperlink to the questionnaire was emailed to all students enrolled in any accredited, entry-level Australian university physiotherapy programme. A reminder email was sent 4 weeks later.

SETTING

Participants completed an online questionnaire.

PARTICIPANTS

526 physiotherapy students from universities across all states with entry-level programmes.

OUTCOME MEASURES

Quantitative data underwent primary descriptive analysis. Thematic analysis was used to synthesise qualitative data.

RESULTS

87% of participants supported the introduction of physiotherapist prescribing in Australia. 91% of participants stated that they would train to prescribe following introduction. Participants identified improvements in clinical and cost effectiveness, timely access to appropriate prescription medicines and optimisation of quality healthcare as key drivers for the introduction.

CONCLUSIONS

Student physiotherapists support the introduction of physiotherapist prescribing in Australia, reporting potential benefits for patients, health services and the physiotherapy profession. Stakeholders should use the results of this study in conjunction with supporting literature to inform future decisions regarding physiotherapist prescribing in Australia.

Perceptions about the implementation of physiotherapist prescribing in Australia: a national survey of Australian physiotherapists

OBJECTIVES

To explore: (1) the views of Australian physiotherapists regarding potential implementation of non-medical prescribing in Australia, (2) how the geographical location and health sector in which a clinician works may influence their perceptions and (3) the perceptions of Australian physiotherapists about how physiotherapist prescribing might impact the care that the profession can provide.

DESIGN

A cross-sectional descriptive survey using open and closed questions.

SETTING

Participants completed an online questionnaire.

PARTICIPANTS

883 Australian Health Professionals Registration Authority (AHPRA)-registered physiotherapists, working across all states and territories.

OUTCOME MEASURES

An online questionnaire was developed by a panel of subject experts and pretested (n=10) for internal consistency. A hyperlink to the questionnaire was emailed to all members of the Australian Physiotherapy Association. A reminder email was sent 4 weeks later. Quantitative data were analysed descriptively, with use of absolute risk reductions (ARRs) and 95% CIs to determine the likelihood that health sector or geographical location were associated with specific views. Thematic analysis enabled synthesis of the qualitative data.

RESULTS

79.0% participants felt that physiotherapist prescribing should be introduced in Australia, with 71.2% wanting to train as prescribers. Clinical governance, risk management, regulation of clinicians and the development of an education framework were identified as priorities for implementation. Participants working in the private sector were significantly more likely to train as prescribers than those in the public sector (ARR 9.9%; 95% CI 3.5 to 16.4) or educational/research institutions (ARR 23.3%; 95% CI 12.8 to 33.8), with city dwellers significantly more likely to train compared with physiotherapists in remote regions (ARR 19.8%; 95% CI 0.8 to 39.2). Physiotherapist prescribing was predicted to improve efficiency of healthcare delivery, access to medicines and reductions in healthcare costs.

CONCLUSIONS

AHPRA-registered physiotherapists perceive that the introduction of autonomous physiotherapist prescribing would be beneficial for the Australian population and should be introduced. Decision makers should consider the results of this survey in conjunction with cost-benefit and risk analysis when planning the introduction of physiotherapist prescribing.

Independent prescribing by advanced physiotherapists for patients with low back pain in primary care: protocol for a feasibility trial with an embedded qualitative component

INTRODUCTION

Low back pain (LBP) is the most prevalent musculoskeletal condition in the UK. Guidelines advocate a multimodal approach, including prescription of medications. Advanced physiotherapy practitioners (APPs) are well placed to provide this care in primary care. Physiotherapist independent prescribing remains novel, with the first prescribers qualifying in 2014. This feasibility trial aims to evaluate the feasibility, suitability and acceptability of assessing the effectiveness of independent prescribing by APPs for patients with LBP in primary care, to inform the design of a future definitive stepped-wedged cluster trial. METHOD AND ANALYSIS: (1) Trial component. An APP (registered prescriber) will complete the initial participant consultation. If prescription drugs are required within the multimodal physiotherapeutic context, these will be prescribed. Patient-reported outcome measures will be completed prior to initial assessment and at 6 and 12 weeks to assess feasibility of follow-up and data collection procedures. Accelerometers will be fitted for 7 days to assess physical activity, sedentary behaviour and feasibility of use. (2) Embedded qualitative component. A focus group and semistructured interviews will be used to evaluate the views and experiences of the participants and APPs respectively, about the feasibility, suitability and acceptability of the proposed full trial. A Consolidated Standards of Reporting Trials diagram will be used to analyse feasible eligibility, recruitment and follow-up rates. Descriptive analysis of the data will be completed to evaluate procedures. Thematic analysis will be used to analyse and synthesise the qualitative data.

ETHICS AND DISSEMINATION

Measures of central sensitisation and their measurement properties in the adult musculoskeletal trauma population: a protocol for a systematic review and data synthesis

INTRODUCTION

Pain following musculoskeletal trauma is common with poor outcomes and disability well documented. Pain is complex in nature and can include the four primary mechanisms of pain: nociceptive, neuropathic, inflammatory and central sensitisation (CS). CS can be measured in multiple ways; however, no systematic review has evaluated the measurement properties of such measures in the musculoskeletal trauma population. This systematic review aims to evaluate the measurement properties of current measures of CS in this population.

METHODS/ANALYSIS

This protocol is informed and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis-P. MEDLINE, EMBASE, CINAHL, ZETOC, Web of Science, PubMed and Google Scholar as well as key journals and grey literature will be searched in two stages to (1) identify what measures are being used to assess CS in this population and (2) evaluate the measurement properties of the identified measures. Two independent reviewers will conduct the search, extract the data, assess risk of bias for included studies and assess overall quality. The Consensus-based Standards for the selection of Health Measurement Instruments Risk of Bias Checklist and a modified Grading of Recommendations, Assessment, Development and Evaluation guidelines will be used. Meta-analysis will be conducted if deemed appropriate. Alternatively, a narrative synthesis will be conducted and summarised per measurement property per outcome measure.

ETHICS AND DISSEMINATION

This review will aid clinicians in using the most appropriate tool for assessing central sensitisation in this population and is the first step towards a more standardised approach in pain assessment. The results of this study will be submitted to a peer reviewed journal and presented at conferences.

Effect of a combined programme of dietary restriction and physical activity on the physical function and body composition of obese middle-aged and older adults with knee OA (DRPA): protocol for a feasibility study

INTRODUCTION

Knee osteoarthritis (OA) is the most common chronic illness among older adults. Up to the submission date of this protocol, there are no published UK studies reporting the efficacy of a combined intervention programme of physical activity and dietary restriction on the musculoskeletal function of obese older adults with knee OA in spite of the clinical recommendation for exercise and diet for people with knee OA. The aim of this study is to assess the feasibility and acceptability of a combined dietary restriction and physical activity intervention programme and collect preliminary data.

METHOD AND ANALYSIS

This single-arm intervention study is scheduled to begin in September 2017 and conclude in November 2018. It will take place at the Royal Orthopaedic Hospital (ROH), Birmingham and the School of Sport, Exercise and Rehabilitation Sciences (SportExR), University of Birmingham. Participants will receive a physiotherapy usual care programme for knee OA for 1 month, after which they will continue to exercise in their local gym/leisure facility for 3 months. Participants will also follow dietary restriction throughout the 4-month intervention. Mixed analysis techniques will be used to analyse the quantitative and qualitative outcome measures.

ETHICS AND DISSEMINATION

It is approved by ROH R&D Foundation Trust and the Health Research Authority. The Consort Guidelines and checklist will be reviewed prior to generating any publications for the trial to ensure they meet the standards required for submission to high-quality peer-reviewed journals.

Care home resident and staff perceptions of the acceptability of nutrition intervention trial procedures: a qualitative study embedded within a cluster randomised feasibility trial

OBJECTIVES

To examine care home resident and staff perceptions of the acceptability of participating in a feasibility trial evaluating nutritional interventions in the treatment of malnutrition.

DESIGN

Exploratory qualitative methodology was used to gather descriptions of resident and staff perceptions of trial procedures, using semi-structured interviews with residents and focus groups with staff. The interviews were used to explore individual perceptions of the acceptability of the assigned intervention and the outcomes measured. Focus groups were used to explore staff experiences of trial participation and perspectives of nutritional support interventions.

SETTING

The study was embedded within a cluster randomised feasibility trial, which randomised six care homes to provide standard care (SC), food-based (FB) intervention or oral nutritional supplement (ONS) intervention to residents with, or at risk of, malnutrition.

PARTICIPANTS

Residents in the trial with capacity to consent (n=7) formed the sampling frame for inclusion. Four agreed to be approached by the researcher and to take part in the individual interviews. All were women, representing two arms of the trial (ONS and SC). Twelve staff participated in six focus groups, one at each care home. All participants were women, representing all three arms of the trial.

RESULTS

Major themes that emerged from both interviews and focus groups included the perceived acceptability of trial involvement, the value of residents completing participant-reported outcome measures and the challenges associated with outcomes measurement in this setting. Themes that emerged from the focus groups alone, included the importance of individualising an intervention, and the perceived value of FB and ONS interventions and dietetic input.

CONCLUSIONS

Residents and staff perceived involvement in a trial evaluating nutritional interventions to be acceptable, although the challenges associated with research in this setting were acknowledged. Resident preferences were highlighted by staff as an important consideration when implementing a nutrition support plan.

Development and validation of two clinical prediction models to inform clinical decision-making for lumbar spinal fusion surgery for degenerative disorders and rehabilitation following surgery: protocol for a prospective observational study

INTRODUCTION

Potential predictors of poor outcome will be measured at baseline: (1) preoperatively to develop a clinical prediction model to predict which patients are likely to have favourable outcome following lumbar spinal fusion surgery (LSFS) and (2) postoperatively to predict which patients are likely to have favourable long-term outcomes (to inform rehabilitation).

METHODS AND ANALYSIS

Prospective observational study with a defined episode inception of the point of surgery. Electronic data will be collected through the British Spine Registry and will include patient-reported outcome measures (eg, Fear-Avoidance Beliefs Questionnaire) and data items (eg, smoking status). Consecutive patients (≥18 years) undergoing LSFS for back and/or leg pain of degenerative cause will be recruited.

EXCLUSION CRITERIA

LSFS for spinal fracture, inflammatory disease, malignancy, infection, deformity and revision surgery. 1000 participants will be recruited (n=600 prediction model development, n=400 internal validation derived model; planning 10 events per candidate prognostic factor). The outcome being predicted is an individual's absolute risk of poor outcome (disability and pain) at 6 weeks (objective 1) and 12 months postsurgery (objective 2). Disability and pain will be measured using the Oswestry Disability Index (ODI), and severity of pain in the previous week with a Numerical Rating Scale (NRS 0-10), respectively. Good outcome is defined as a change of 1.7 on the NRS for pain, and a change of 14.3 on the ODI. Both linear and logistic (to dichotomise outcome into low and high risk) multivariable regression models will be fitted and mean differences or ORs for each candidate predictive factor reported. Internal validation of the derived model will use a further set of British Spine Registry data. External validation will be geographical using two spinal registries in The Netherlands and Switzerland.

Ethical approval (University of Birmingham ERN_17-0446A). Dissemination through peer-reviewed journals and conferences.

Development of a screening tool to predict the risk of chronic pain and disability following musculoskeletal trauma: protocol for a prospective observational study in the United Kingdom

INTRODUCTION

Pain is an expected and appropriate experience following traumatic musculoskeletal injury. By contrast, chronic pain and disability are unhelpful yet common sequelae of trauma-related injuries. Presently, the mechanisms that underlie the transition from acute to chronic disabling post-traumatic pain are not fully understood. Such knowledge would facilitate the development and implementation of precision rehabilitation approaches that match interventions to projected risk of recovery, with the aim of preventing poor long-term outcomes. The aim of this study is to identify a set of predictive factors to identify patients at risk of developing ongoing post-traumatic pain and disability following acute musculoskeletal trauma. To achieve this, we will use a unique and comprehensive combination of patient-reported outcome measures, psychophysical testing and biomarkers.

METHODS AND ANALYSIS

A prospective observational study will recruit two temporally staggered cohorts (n=250 each cohort; at least 10 cases per candidate predictor) of consecutive patients with acute musculoskeletal trauma aged ≥16 years, who are emergency admissions into a Major Trauma Centre in the United Kingdom, with an episode inception defined as the traumatic event. The first cohort will identify candidate predictors to develop a screening tool to predict development of chronic and disabling pain, and the second will allow evaluation of the predictive performance of the tool (validation). The outcome being predicted is an individual's absolute risk of poor outcome measured at a 6-month follow-up using the Chronic Pain Grade Scale (poor outcome ≥grade II). Candidate predictors encompass the four primary mechanisms of pain: nociceptive (eg, injury location), neuropathic (eg, painDETECT), inflammatory (biomarkers) and nociplastic (eg, quantitative sensory testing). Concurrently, patient-reported outcome measures will assess general health and psychosocial factors (eg, pain self-efficacy). Risk of poor outcome will be calculated using multiple variable regression analysis.

Effect of physical activity and dietary restriction interventions on weight loss and the musculoskeletal function of overweight and obese older adults with knee osteoarthritis: a systematic review and mixed method data synthesis

BACKGROUND

Despite the clinical recommendation of exercise and diet for people with knee osteoarthritis (OA), there are no systematic reviews synthesising the effectiveness of combining physical activity and dietary restriction interventions on the musculoskeletal function of overweight and obese older adults with knee OA.

OBJECTIVE

To evaluate the effectiveness of combined physical activity and dietary restriction programmes on body weight, body mass index (BMI) and the musculoskeletal function of overweight and obese older adults with knee OA.

INFORMATION SOURCES

A detailed search strategy was applied to key electronic databases (Ovid, Embase, Web of Science andCumulative Index to Nursing and Allied Health Literature (CINAHL)) for randomised controlled trials (RCTs) published in English prior to 15 January 2017.

PARTICIPANTS

Participants with BMI ≥25 kg/m², aged ≥55 years of age and with radiographic evidence of knee OA.

INTERVENTIONS

Physical activity plus dietary restriction programmes with usual care or exercise as the comparators.

OUTCOME MEASURES

Primary outcome measures were body weight, BMI or musculoskeletal function. Secondary outcome measures were pain and quality of life.

RESULTS

One pilot and two definitive trials with n=794 participants were included. Two articles reporting additional data and outcome measures for one of the RCTs were identified. All included RCTs had an unclear risk of bias. Meta-analysis was only possible to evaluate mobility (6 min walk test) at 6 months and the pooled random effect 15.05 (95% CI -11.77 to 41.87) across two trials with n=155 participants did not support the combined intervention programme. Narrative synthesis showed clear differences in favour of a reduced body weight and an increased 6 min walk in the intervention group compared with control groups.

CONCLUSION

The quality of evidence of benefit of combining exercise and dietary interventions in older overweight/obese adults with knee OA is unclear.

Identification of adult knee primary bone tumour symptom presentation: A qualitative study

OBJECTIVES

The aim of this study was to identify the symptom presentation of adult knee primary bone tumours from onset to Consultant diagnosis, from combined patient and healthcare professional perspectives.

MATERIALS AND METHODS

A qualitative study using in-depth semi-structured interviews recruited a purposive sample of adult patients with a knee primary bone tumour (n = 8) and healthcare professionals with expertise in orthopaedic oncology (n = 6). Following informed consent, recorded interviews explored participants' experiences of symptom presentation. A grounded theory approach was utilised to analyse transcribed data, producing themes. Methods to increase rigour and trustworthiness were employed. Recruitment continued until data saturation was achieved.

RESULTS

Four key themes were established: 1] Symptoms started with intermittent pain which became more severe and more constant, 2] Pain was mechanical in nature but became more difficult to ease; 3] The pain story was unusual with a protracted symptom duration and failure to improve with conservative treatment; 4] Non-painful symptoms included swelling, and systemic signs were uncommon. More similarities between healthcare professionals' and patients' perceptions were found at Consultant diagnosis compared to onset.

CONCLUSION

New insights of symptom presentation, particularly in the early stages have been provided which are not reflected in current guidelines. Although starting similarly to routine musculoskeletal presentations, a number of distinctive features may enable earlier diagnosis.

The effect of work-based mentoring on patient outcome in musculoskeletal physiotherapy: study protocol for a randomised controlled trial

BACKGROUND

Despite persistent calls to measure the effectiveness of educational interventions on patient outcomes, few studies have been conducted. Within musculoskeletal physiotherapy, the effects of postgraduate clinical mentoring on physiotherapist performance have been assessed, but the impact of this mentoring on patient outcomes remains unknown. The objective of this trial is to assess the effectiveness of a work-based mentoring programme to facilitate physiotherapist clinical reasoning on patient outcomes in musculoskeletal physiotherapy.

METHODS/DESIGN

A stepped wedge cluster randomised controlled trial (CRCT) has been designed to recruit a minimum of 12 senior physiotherapists who work in musculoskeletal outpatient departments of a large National Health Service (NHS) organization. Participating physiotherapists will be randomised by cluster to receive the intervention at three time periods. Patients will be blinded to whether their physiotherapist has received the intervention. The primary outcome measure will be the Patient-Specific Functional Scale; secondary outcome measures will include the EQ-5D, patient activation, patient satisfaction and physiotherapist performance. Sample size considerations used published methods describing stepped wedge designs, conventional values of 0.80 for statistical power and 0.05 for statistical significance, and pragmatic groupings of 12 participating physiotherapists in three clusters. Based on an intergroup difference of 1.0 on the PSFS with a standard deviation of 2.0, 10 patients are required to complete outcome measures per physiotherapist, at time period 1 (prior to intervention roll-out) and at each of time periods 2, 3 and 4, giving a sample size of 480 patients. To account for the potential loss to follow-up of 33%, 720 sets of patient outcomes will be collected.All physiotherapist participants will receive 150 hours of mentored clinical practice as the intervention and usual in-service training as control. Consecutive, consenting patients attending treatment by the participating physiotherapists during data collection periods will complete outcome measures at baseline, discharge and 12 months post-baseline. The lead researcher will be blinded to the allocation of the physiotherapist when analyzing outcome data; statistical analysis will involve classical linear models incorporating both an intervention effect and a random intercept term to reflect systematic differences among clusters.

A modified Delphi consensus study to identify UK osteopathic profession research priorities

There is an increasing emphasis to take an evidence-based approach to healthcare. To obtain evidence relevant to the osteopathic profession a clear research direction is required based on the views of stakeholders in the osteopathic profession. A modified Delphi consensus approach was conducted to explore the views of osteopaths and patients regarding research priorities for osteopathy. Osteopaths and patients were invited to complete an online questionnaire survey (n = 145). Round 1 requested up to 10 research priority areas and the rationale for their selection. All of the themes from Round 1 were fed back verbatim, and in Round 2 participants were asked to rank the importance of the research priorities on a 5-point Likert scale. Finally, in Round 3 participants were asked to rank the importance of a refined list of research topics which had reached consensus. Descriptive analysis and use of Kendall's coefficient of concordance enabled interpretation of consensus. The response rate for Round 1 was 87.9% and identified 610 research priority areas. Round 2 identified 69 research themes as important, and Round 3 identified 20 research priority topic areas covering four themes: effectiveness of osteopathic treatment (7 areas prioritised), role of osteopathy: the management of four conditions were prioritised, risks with osteopathic treatment (two areas prioritised) and outcomes of osteopathic treatment (two areas prioritised). The findings will be taken forward to develop the research strategy for osteopathy.

Intrarater and interrater reliability of the Anteromedial Reach Test in healthy participants

Background

The Anteromedial Reach Test is a performance-based outcome measure for evaluating dynamic knee stability in patients with anterior cruciate ligament injury. No previously published study has adequately evaluated intrarater or interrater reliability of the Anteromedial Reach Test, so the purpose of this study was to assess these measurement properties in healthy participants prior to their investigation in patients with anterior cruciate ligament injury.

Methods

Two raters (A and B) tested 39 healthy university staff and students (20 men, 19 women). For the intrarater reliability investigation, rater A tested participants on three separate test occasions (days 1, 2, and 3) at the same time of day. For the interrater reliability investigation, raters A and B independently tested participants on the same test occasion (day 3).

Results

There was no significant systematic bias between test occasions or raters. Values of the intraclass correlation coefficient (2,1) were 0.96 for intrarater reliability of both the dominant leg and nondominant leg and 0.97 (dominant leg) and 0.98 (nondominant leg) for interrater reliability. Values for the standard error of measurement were 1.46 (dominant leg) and 1.62 (nondominant leg) for the intrarater investigation, and 1.26 (dominant leg) and 1.04 (nondominant leg) for the interrater investigation. At the 90% confidence level, the minimum detectable change was 3.8% and the error in an individual’s score at a given point in time was ±2.7%.

Conclusion

The Anteromedial Reach Test demonstrated excellent intrarater and interrater reliability in healthy participants. This provides a basis for future investigation of the measurement properties of the Anteromedial Reach Test in patients with anterior cruciate ligament injury.

Distance reached in the Anteromedial Reach Test as a function of learning and leg length

The anteromedial reach test (ART) is a new outcome measure for assessing dynamic knee stability in anterior cruciate ligament-injured patients. The effect of learning and leg length on distance reached in the ART was examined. Thirty-two healthy volunteers performed 15 trials of the ART on each leg. There was a moderate correlation (r = .44-.50) between reach distance and leg length, therefore reach distances were normalized for leg length. Normalized reach distance increased significantly over the 15 trials (p < .01), reaching a plateau after 8 trials, identified by a moving average graph. It is recommended that participants be afforded eight practice trials and that reach distances be normalized by expressing them as a percentage of leg length.
