Variability in the prevalence of depression among adults with chronic pain: UK Biobank analysis through clinical prediction models

BACKGROUND

The prevalence of depression among people with chronic pain remains unclear due to the heterogeneity of study samples and definitions of depression. We aimed to identify sources of variation in the prevalence of depression among people with chronic pain and generate clinical prediction models to estimate the probability of depression among individuals with chronic pain.

METHODS

Participants were from the UK Biobank. The primary outcome was a "lifetime" history of depression. The model's performance was evaluated using discrimination (optimism-corrected C statistic) and calibration (calibration plot).

RESULTS

Analyses included 24,405 patients with chronic pain (mean age 64.1 years). Among participants with chronic widespread pain, the prevalence of having a "lifetime" history of depression was 45.7% and varied (25.0-66.7%) depending on patient characteristics. The final clinical prediction model (optimism-corrected C statistic: 0.66; good calibration on the calibration plot) included age, BMI, smoking status, physical activity, socioeconomic status, gender, history of asthma, history of heart failure, and history of peripheral artery disease. Among participants with chronic regional pain, the prevalence of having a "lifetime" history of depression was 30.2% and varied (21.4-70.6%) depending on patient characteristics. The final clinical prediction model (optimism-corrected C statistic: 0.65; good calibration on the calibration plot) included age, gender, nature of pain, smoking status, regular opioid use, history of asthma, pain location that bothers you most, and BMI.

CONCLUSIONS

There was substantial variability in the prevalence of depression among patients with chronic pain. Clinically relevant factors were selected to develop prediction models. Clinicians can use these models to assess patients' treatment needs. These predictors are convenient to collect during daily practice, making it easy for busy clinicians to use them.

Effectiveness of an eHealth-Delivered Program to Empower People With Musculoskeletal Pain in Rural Australia: A Randomized Controlled Trial

OBJECTIVE

Our objective was to evaluate the effectiveness of a three-month physiotherapist-delivered eHealth physical activity program compared with usual care to improve function in adults with low back pain or knee osteoarthritis in rural Australia.

METHODS

This was a parallel, two-group, pragmatic, superiority, randomized controlled trial involving three- and six-month posttreatment follow-ups. There was a total of 156 adults with chronic nonspecific low back pain (n = 97) or knee osteoarthritis (n = 59) from rural Australia. The intervention involved an eHealth physical activity and an exercise program that included five to eight teleconsultations with a physiotherapist (primary time point three months) or usual care (eg, general practitioner, physiotherapy, and pain medication). The primary outcome was the Patient-Specific Functional Scale (0-30), with a three-point difference between groups being considered the minimum clinically important difference.

RESULTS

Participants receiving the eHealth intervention (n = 78) reported significantly greater and clinically worthwhile improvements in function (mean between-group difference 3.6; 95% confidence interval [CI] 1.3-5.9) compared to participants receiving usual care (n = 78). Small but statistically significantly greater improvements in disability (7.2 of 100; 95% CI 2.1-12.3) and quality of life (4.5 of 100; 95% CI 0.0-9.0) also favored the eHealth group. No clinical or statistical differences between groups were found for the secondary outcomes of pain, coping skills, and physical activity levels.

CONCLUSION

A physiotherapist-delivered eHealth intervention is effective and provides clinically meaningful improvements in function compared to usual care for people with musculoskeletal pain in rural communities. These findings highlight the potential for eHealth-based programs to improve access to evidence-based exercise interventions for people with musculoskeletal pain in rural communities.

Outcome Heterogeneity in Prehabilitation Trials-Are We Comparing Apples and Oranges?

INTRODUCTION

Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery.

METHODS

A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality).

RESULTS

A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]).

CONCLUSIONS

Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.

Clinical guidelines are silent on the recommendation of physical activity and exercise therapy for low back pain: A systematic review

OBJECTIVES

To synthesise and evaluate the quality of the recommendations for exercise therapy and physical activity from guidelines for the prevention and/or management of low back pain.

DESIGN

Systematic review.

METHODS

Included clinical practice guidelines for the management of low back pain published between 2014 and 2022 and searched in 9 databases until September 2022. The quality of evidence was evaluated with the Appraisal of Guidelines, Research and Evaluation tool (AGREE-II instrument).

RESULTS

After screening 3448 studies, 18 clinical practice guidelines were included in this review. Only five (27 %) guidelines were judged as having a satisfactory quality of evidence (i.e., rigour of development and applicability), and 13 (72 %) of guidelines are discussed and rated as critical. Regarding physical activity, no guidelines provided recommendations for the primary prevention of low back pain or incorporated adequate physical activity aspects considering type, dosage, frequency, and intensity. For exercises, all (100 %) guidelines recommended at least one type of supervised exercise in the management of low back pain, and 16 (88 %) provided an overall recommendation for people to stay active.

CONCLUSIONS

Guidelines offer minimal or, sometimes, no detail regarding physical activity or specific exercise regimens for the management and prevention of low back pain. When some guidance is provided, the recommendations typically lack specificity concerning the type, intensity, duration, and frequency of exercise and, in many cases, they represent a combination of scarce available evidence and stakeholder perspectives.

A review of patient recruitment in randomised controlled trials of preoperative exercise

BACKGROUND

Randomised controlled trials (RCTs) are considered the gold standard design to determine the effectiveness of an intervention, as the only method of decreasing section bias and minimising random error. However, participant recruitment to randomised controlled trials is a major challenge, with many trials failing to recruit the targeted sample size accordingly to the planned protocol. Thus, the aim of this review is to detail the recruitment challenges of preoperative exercise clinical trials.

METHODS

A comprehensive search was performed on MEDLINE, Embase, The Cochrane Library, CINAHL, AMED and PsycINFO from inception to July 2021. Randomised controlled trials investigating the effectiveness of preoperative exercise on postoperative complication and/or length of hospital stay in adult cancer patients were included. Main outcomes included recruitment rate, retention rate, number of days needed to screen and recruit one patient and trial recruitment duration. Descriptive statistics were used to summarise outcomes of interest.

RESULTS

A total of 27 trials were identified, including 3656 patients screened (N = 21) and 1414 randomised (median recruitment rate (interquartile range) = 53.6% (25.2%-67.6%), N = 21). The sample size of the included trials ranged from 19 to 270 (median = 48.0; interquartile range = 40.0-85.0) and the duration of trial recruitment ranged from 3 to 50 months (median = 19.0 months; interquartile range = 10.5-34.0). Overall, a median of 3.6 days was needed to screen one patient, whereas 13.7 days were needed to randomise one participant. Over the trials duration, the median dropout rate was 7.9%. Variations in recruitment outcomes were observed across trials of different cancer types but were not statistically significant.

CONCLUSION

The recruitment of participants to preoperative exercise randomised controlled trials is challenging, but patient retention appears to be less of a problem. Future trials investigating the effectiveness of a preoperative exercise programme following cancer surgery should consider the time taken to recruit patients. Strategies associated with improved recruitment should be investigated in future studies.

The impact of aggregate positive lifestyle behaviors on low back pain resilience and care seeking

BACKGROUND CONTEXT

Low back pain (LBP) is a global issue, and the high associated costs are mainly attributed to a small proportion of people with LBP who seek care. Importantly, the impact of aggregate positive lifestyle behaviors on LBP resilience and care seeking is not known.

PURPOSE

This study aimed to evaluate the relationship between positive lifestyle behaviors and LBP resilience.

STUDY DESIGN

This study was a prospective longitudinal cohort study.

PATIENT SAMPLE

Data was collected as part of the AUstralian Twin BACK Study (AUTBACK). Participants who reported a lifetime previous history of LBP at baseline were included in this analysis (n = 340).

OUTCOME MEASURES

The outcomes of interest were the number of weeks without activity limiting LBP and total number of days of healthcare usage, health practitioner care, self-management care, and medication intake.

METHODS

A lifestyle behavior score was built using variables of body mass index (BMI), physical activity, smoking status, and sleep quality. Negative binomial regression analyses were used to assess the relationship between the positive lifestyle behavior score and the count outcomes of number of weeks without activity limiting LBP and number of days participants used care.

RESULTS

After adjusting for covariates, no association was found between participants' positive lifestyle behavior score and their number of weeks without activity limiting LBP (IRR: 1.02, 95% CI 1.00-1.05). There was a statistically significant relationship between higher positive lifestyle behavior scores and fewer number of days of participants' total healthcare usage (IRR:0.69, 95% CI 0.56-0.84), healthcare practitioner visits (IRR:0.62, 95% CI 0.45-0.84), use of self-management strategies (IRR:0.74, 95% CI 0.60-0.91), and use of pain medication (IRR:0.55, 95% CI 0.44-0.68).

CONCLUSION

People who adopt optimal lifestyle behaviors, such as engaging in adequate physical activity, achieving optimal quality sleep, maintaining an ideal BMI, and not smoking, may not experience less time suffering from activity limiting LBP, but are less likely to use healthcare and pain medication for their LBP.

Barriers and facilitators to reducing paracetamol use in low back pain: A qualitative study

BACKGROUND

Paracetamol is widely used for low back pain (LBP), but research questions its efficacy and safety. Patient education booklets have been explored for promoting deprescribing, but barriers and facilitators specific to LBP deprescribing remain unexamined.

OBJECTIVE

To identify contextual factors facilitating and obstructing successful deprescribing of paracetamol for LBP after receiving an educational booklet.

STUDY DESIGN

This study is part of an uncontrolled cohort feasibility study (CEASE NOW) in the community, recruiting from Musculoskeletal Australia and painaustralia.

PATIENT SAMPLE

Twenty-four participants with acute, sub-acute, or chronic LBP, self-reporting paracetamol consumption, were included.

METHODS

Thematic content analysis was used to analyze qualitative data on barriers and facilitators. Data were categorized by deprescribing outcomes: i) successful deprescribing, ii) attempted but failed, or iii) no attempt. Semi-structured telephone interviews were conducted within one week after each participant completed the one-month follow-up.

RESULTS

Successful deprescribing was facilitated by supportive healthcare professionals, willingness, high self-efficacy, fear of future illness, and diverse strategies for deprescribing plans. Barriers included unsupportive healthcare professionals and fear of flare-ups. Participants not attempting deprescribing believed it unnecessary, perceived it as effortful, unquestioningly trusted healthcare professionals, and lacked risk awareness.

CONCLUSIONS

Support from healthcare professionals, patient willingness, perceived necessity, risk awareness, effort, and varied strategies influence deprescribing outcomes for LBP patients using paracetamol. Addressing these factors is crucial when designing interventions to promote safe and effective deprescribing in LBP management.

Positive lifestyle behaviours and emotional health factors are associated with low back pain resilience

PURPOSE

To evaluate the relationship between lifestyle behaviours, emotional health factors, and low back pain (LBP) resilience.

METHODS

This retrospective longitudinal study utilised 1,065 twins with a recent history of LBP from the Washington State Twin Registry. A lifestyle behaviour score was built using variables of body mass index, physical activity engagement, sleep quality, smoking status, and alcohol consumption. An emotional health score was built using variables of the absence of depressed mood, perceived stress, and active coping. The main outcome was LBP resilience, assessed as recovery ("bouncing back"), and sustainability (maintaining high levels of function despite LBP).

RESULTS

After adjusting for covariates, there was no relationship between the lifestyle behaviour score (OR 1.05, 95% CI 0.97-1.15, p = 0.218) and the emotional health score (OR 1.08, 95% CI 0.98-1.19, p = 0.142) with the likelihood of recovering from LBP. There was however, evidence of a positive association between the lifestyle behaviour score (β 0.20, 95% CI 0.04-0.36, p = 0.013), the emotional health score (β 0.22, 95% CI 0.00-0.43, p = 0.049), and greater levels of sustainability. These results were confirmed by a within-pair analysis (lifestyle behaviour score: β 1.79, 95% CI 0.05-3.53, p = 0.043) and (emotional health score: β 0.52, 95% CI 0.09-0.96, p = 0.021) adjusting for genetic and early shared environmental confounding.

CONCLUSION

Findings from this study suggest that people who adopt optimal lifestyle behaviours and positive emotional factors are more likely to be resilient and maintain high levels of function despite suffering from LBP.

Association of chronic musculoskeletal pain with mortality among UK adults: A population-based cohort study with mediation analysis

BACKGROUND

We aimed to quantify the association between chronic musculoskeletal pain and all-cause mortality, and to investigate the extent to which this association is mediated by physical activity, smoking status, alcohol consumption, and opioid use.

METHODS

For this population-based cohort study, we used data from UK Biobank, UK between baseline visit (2006-2010) to 18th December 2020. We assessed the associations between chronic musculoskeletal pain and all-cause mortality using a Cox proportional hazards model. We performed causal mediation analyses to examine the proportion of the association between chronic musculoskeletal pain and all-cause mortality.

FINDINGS

Of the 384,367 included participants, a total of 187,269 participants reported chronic musculoskeletal pain. Higher number of pain sites was associated with increased risk of all-cause mortality compared to having no pain (e.g., four sites vs no site of pain, Hazard Ratio [HR] 1.46, 95% Confidence Interval [CI] 1.35 to 1.57). The multiple mediator analyses showed that the mediating proportions of all four mediators ranged from 53.4% to 122.6%: among participants with two or more pain sites, the effect estimate reduced substantially, for example, HR reduced from 1.25 (95% CI: 1.21 to 1.30; two pain sites) to 1.07 (95% CI: 1.01 to 1.11; two pain sites).

INTERPRETATION

We found that higher number of pain sites was associated with increased risk of all-cause mortality compared to having no pain, and at least half of the association of chronic musculoskeletal pain with increased all-cause mortality may be accounted for by four mediators.

Clinical Course of Pain and Function Following Total Knee Arthroplasty: A Systematic Review and Meta-Regression

BACKGROUND

Total knee arthroplasty (TKA) is widely considered a successful intervention for osteoarthritis and other degenerative knee diseases. This study addresses the need for a high-quality meta-analysis that outlines the clinical course of pain and function post-TKA.

METHODS

The review included prospective cohort studies assessing pain or function of patients undergoing primary TKA at baseline (preoperatively) and at least 2 additional time points including one at least 12 months postoperatively. Two reviewers independently screened references, extracted data, and assessed risk of bias using the Quality in Prognosis Studies tool. The time course of recovery of pain and function was modeled using fractional polynomial meta-regression.

RESULTS

In total, 191 studies with 59,667 patients were included, most with low risk of bias. The variance-weighted mean pain score (/100, 0 = no pain) was 64.0 (95% confidence interval [CI] 60.2-67.7) preoperatively, 24.1 (95% CI 20.3-27.9) at 3 months, 20.4 (95% CI 16.7-24.0) at 6 months, and 16.9 (95%CI 13.6-20.3) at 12 months, and remained low (10.1; 95% CI 4.8-15.4) at 10 years postoperatively. The variance-weighted mean function score (/100, 0 = worst function) was 47.1 (95% CI 45.7-48.4) preoperatively, 72.8 (95% CI 71.3-74.4) at 3 months, 76.3 (95% CI 74.7-77.8) at 6 months, and 78.1 (95%CI 76.4-79.7) at 12 months. Function scores were good (79.7; 95% CI 77.9-81.5) at 10 years postoperatively.

CONCLUSION

Patients undergoing primary TKA can expect a large and rapid but incomplete recovery of pain and function in the first postoperative year. At 10 years, the gains in pain scores may still remain while there is an improvement in function.

Individualised, targeted step count intervention following gastrointestinal cancer surgery: The Fit-4-Home randomised clinical trial

BACKGROUND

To determine the effectiveness of an individualised, daily targeted step count intervention and usual care compared with usual care alone on improving surgical and patient reported outcomes.

METHODS

The Fit-4-Home trial was a pragmatic, randomised controlled trial conducted from April 2019 to February 2021. Patients undergoing elective surgery for liver, stomach or pancreatic cancer in two Australian hospitals were recruited. Participants were randomly allocated to receive an individualised, targeted step count intervention and usual care (intervention) or usual care alone (control). A wearable activity tracker was provided to the intervention group to monitor their daily step count target. Primary outcome was the length of stay in the gastrointestinal ward. Secondary outcomes included postoperative complication rates, discharge destination, quality of life, physical activity, pain, fatigue, distress and hospital re-admission within 30 days. Outcome measures were compared between groups using non-parametric statistics.

RESULTS

Of the 96 patients recruited, 47 were randomised to the intervention group and 49 were randomised to the control group. The median (interquartile) length of stay in the ward was 7 days (5.0-13.0) in the intervention group and 7 days (5.0- 12.0) in the control group (p = 0.330). Fatigue scores were worse in the intervention group when compared to control (p = 0.018). No other differences between groups were observed.

CONCLUSIONS

An individualised, daily targeted step count intervention and usual care did not confer additional benefits in reducing the length of stay in the ward compared to usual care alone for patients undergoing gastrointestinal cancer surgery.

Preoperative Cardiopulmonary Exercise Test Associated with Postoperative Outcomes in Patients Undergoing Cancer Surgery: A Systematic Review and Meta-Analyses

BACKGROUNDS

There is mixed evidence on the value of preoperative cardiorespiratory exercise test (CPET) to predict postoperative outcomes in patients undergoing a cancer surgical procedure. The purpose of this review was to investigate the association between preoperative CPET variables and postoperative complications, length of hospital stay, and quality of life in patients undergoing cancer surgery.

METHODS

A search was conducted on MEDLINE, Embase, AMED, and Web of science from inception to April 2020. Cohort studies investigating the association between preoperative CPET variables, including peak oxygen uptake (peak VO₂), anaerobic threshold (AT), or ventilatory equivalent for carbon dioxide (V_E/V_CO2), and postoperative outcomes (complications, length of stay, and quality of life) were included. Risk of bias was assessed using the QUIPS tool. A random-effect model meta-analysis was performed whenever possible.

RESULTS

Fifty-two unique studies, including 10,030 patients were included. Overall, most studies were rated as having low risk of bias. Higher preoperative peak VO₂ was associated with absence of postoperative complications (mean difference [MD]: 2.28; 95% confidence interval [CI]: 1.26-3.29) and no pulmonary complication (MD: 1.47; 95% CI: 0.49-2.45). Preoperative AT and V_E/V_CO2 also demonstrated some positive trends. None of the included studies reported a negative trend.

CONCLUSIONS

This systematic review and meta-analysis demonstrated a significant association between superior preoperative CPET values, especially peak VO₂, and better postoperative outcomes. The assessment of preoperative functional capacity in patients undergoing cancer surgery has the potential to facilitate treatment decision making.

Association of Lumbar Spine Radiographic Changes With Severity of Back Pain-Related Disability Among Middle-aged, Community-Dwelling Women

IMPORTANCE

Previous studies, using mostly cross-sectional data, provide conflicting evidence of an association between lumbar spine radiographic changes and the severity of back pain-related disability. Such conflicting evidence may be associated with widely unnecessary diagnostic imaging of the lumbar spine.

OBJECTIVE

To examine both cross-sectional and longitudinal associations between lumbar spine radiographic changes and the severity of back pain-related disability among middle-aged, community-dwelling women.

DESIGN, SETTING, AND PARTICIPANTS

This population-based prospective cohort study used data from the Chingford 1000 Women Study. Analyses included data collected from year 6 (1994-1996; physical activity was measured), year 9 (1997-1999; treated as baseline), and year 15 (2003-2005), with a total length of follow-up for longitudinal analyses of 6 years. Data were analyzed from April 17 to November 3, 2020.

EXPOSURES

Primary exposure was lumbar spine radiographic changes, defined using the Kellgren-Lawrence (K-L) grade. Secondary exposures were defined using presence of osteophytes and disc space narrowing. The composite score combined the number of lumbar spine segments with definite changes detected on radiographic images (ie, radiographic changes) (K-L grade ≥2, which means at least definite osteophyte and possible narrowing of disc space are present; osteophyte and disc space narrowing grade ≥1, which means at least mild or definite changes are present).

MAIN OUTCOMES AND MEASURES

Self-reported back pain-related disability measured in years 9 and 15 assessed by the St Thomas disability questionnaire.

RESULTS

Among 650 women (mean [SD] age, 61.3 [5.9] years) in cross-sectional analyses and 443 women (mean [SD] age, 60.6 [6.0] years) in longitudinal analyses, there was no evidence to support an association between higher number of lumbar segments with radiographic changes (K-L grade, osteophytes, and disc space narrowing) and more severe back pain-related disability (eg, cross-sectional analyses using the K-L grade; 1 segment vs 0 segment: adjusted odds ratio, 1.22 [95% CI, 0.76-1.96]). No interactions were found of an association between lumbar spine radiographic changes and the severity of back pain-specific disability with age, body mass index, or smoking status.

CONCLUSIONS AND RELEVANCE

In this cohort of middle-aged, community-dwelling women, there was no evidence to support an association between a higher number of lumbar segments with radiographic changes (K-L grade, osteophytes, and disc space narrowing) and more severe back pain-related disability cross-sectionally or over time. These findings provide further evidence against routinely using diagnostic imaging of the lumbar spine.

Comparative Efficacy and Safety of Conservative Care for Pregnancy-Related Low Back Pain: A Systematic Review and Network Meta-analysis

OBJECTIVE

More than one-half of pregnant women experience pregnancy-related low back pain (LBP). Pregnancy-related LBP greatly affects activities of daily life, and although many interventions have been proposed, the optimal treatment for pregnancy-related LBP remains unclear. The purpose of this study was to compare conservative care strategies on their efficacy and safety for women with pregnancy-related LBP through systematic review with pairwise meta-analysis and network meta-analysis.

METHODS

MEDLINE, Embase, the Cochrane Library, AMED, CINAHL, PEDro, PsycINFO, and ClinicalTrials.gov were searched from inception to November 2019. Randomized controlled trials and observational controlled studies were included without restriction to language, sample size, or duration of follow-up. Two independent investigators extracted the data and assessed the risk of bias. The quality of evidence was evaluated through Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

Twenty-three studies were included in the qualitative synthesis (18 randomized controlled trials were included in the network meta-analysis). For women with LBP during pregnancy, progressive muscle relaxation therapy (mean difference = -3.96; 95% CI = -7.19 to -0.74; moderate-quality evidence) and Kinesio Taping (mean difference = -3.71; 95% CI = -6.55 to -0.87; low-quality evidence) reduced pain intensity (Visual Analog Scale, range = 0 to 10) compared with placebo. Moderate-quality evidence suggested that transcutaneous electrical nerve stimulation improved physical function (mean difference = -6.33; 95% CI = -10.61 to -2.05; Roland Morris Disability Questionnaire, range = 0-24) compared with placebo.

CONCLUSION

For patients with LBP during pregnancy, progressive muscle relaxation therapy and Kinesio Taping may help to decrease pain, and transcutaneous electrical nerve stimulation may improve physical function.

IMPACT

This review helps fill the gap in evidence regarding optimal treatment for pregnancy-related LBP.

LAY SUMMARY

If you have LBP during pregnancy, your physical therapist has evidence to support the use of progressive muscle relaxation therapy and Kinesio Taping to help decrease pain and the use of transcutaneous electrical nerve stimulation to help improve physical function.

Feasibility and acceptability of a preoperative exercise program for patients undergoing major cancer surgery: results from a pilot randomized controlled trial

Objective

To establish the feasibility and acceptability of a preoperative exercise program, and to obtain pilot data on the likely difference in key surgical outcomes to inform the sample size calculation for a full-scale trial.

Design

Pilot randomized controlled trial.

Setting

Royal Prince Alfred Hospital, Sydney, Australia.

Subjects

We included patients undergoing elective pelvic exenteration or cytoreductive surgery aged 18 to 80 years, who presented to the participating gastrointestinal surgeon at least 2 weeks prior to surgery. Patients presenting cognitive impairment, co-morbidity preventing participation in exercise, inadequate English language, currently participating in an exercise program or unable to attend the exercise program sessions were excluded.

Methods

Participants were randomized to a 2–6 weeks preoperative, face-to-face, individualised exercise program or to usual care. Feasibility was assessed with consent rates to the study, and for the intervention group, retention and adherence rates to the preoperative exercise program. Acceptability of the exercise program was assessed with a semi-structured questionnaire exploring the advice received and the amount, duration and intensity of the exercise program. In addition, postoperative complication rates (Clavien-Dindo), length of hospital stay and self-reported measures of health-related quality of life (SF-36v2) were collected at baseline, day before surgery and in-hospital up to discharge from hospital.

Results

Of 122 patients screened, 26 (21%) were eligible and 22 (85%) accepted to participate in the trial and were randomized to the intervention (11; 50%) or control group (11; 50%). The median age of the include participants was 63 years. Adherence to the preoperative exercise sessions was 92.7%, with all participants either satisfied (33%) or extremely satisfied (67%) with the overall design of the preoperative exercise program. No significant differences in outcomes were found between groups.

Conclusions

The results of our pilot trial demonstrate that a preoperative exercise program is feasible and acceptable to patients undergoing major abdominal cancer surgery. There is an urgent need for a definite trial investigating the effectiveness of a preoperative exercise program on postoperative outcomes in patients undergoing major abdominal cancer surgery. This could potentially reduce postoperative complication rates, length of hospital stay and subsequently overall health care costs.

Are people in the bush really physically active? A systematic review and meta-analysis of physical activity and sedentary behaviour in rural Australians populations

Background

Physical inactivity is a major risk factor for non-communicable disease and premature mortality. People who live in rural settings are usually regarded as more physically active than those living in urban areas, however, direct comparisons between these populations are scarce. We aimed to summarise the prevalence of physical inactivity and sedentary behaviour in rural settings in Australia, compared to urban counterparts.

Methods

We searched six databases (AMED, Embase, Medline; CINAHL, SPORTDiscus; and RURAL) and identified 28 observational studies that investigated the levels of physical inactivity and/or sedentary behaviour in adults aged 18 years and over in rural Australia. Random effects meta-analysis was used to generate pooled prevalence estimates.

Results

Physical inactivity was four percentage points (95% confidence interval (CI) = 0.4 to 8) higher in rural populations compared to urban populations. There was a one percentage point (95% CI = -3 to 5) prevalence difference of physical activity in the rural populations. Rural populations reported on average 7.8 hours of sedentary time per day (95% CI = 5 to 10) and the prevalence of high levels of sedentary behaviour (≥to 8 hours per day) was 7% (95% CI = -8 to -7) greater in urban areas compared to rural areas.

Conclusions

People living in rural areas are just as physically inactive as people who live in urban areas. Our findings challenge the popular views that rural lifestyles result in people engaging more frequently in physical activity. Public health campaigns promoting physical activity in rural settings are just as necessary as in urban settings.

Return to self-reported physical activity level after an event of acute low back pain

Background

Regular physical activity participation is known to promote better mobility and coordination. Although previous research has established that lack of physical activity participation may increase the risk of developing low back pain, the role of physical activity as a predictor of recovery among symptomatic individuals remains unclear.

Objective

To evaluate whether: (i) the level of physical activity participation before an acute episode of low back pain predicts recovery within 12 months following the acute pain episode (i.e. index episode); and (ii) participants return to their pre-pain level of physical activity participation 12 months from the index episode.

Design

This study used longitudinal data from the TRIGGERS case-crossover study.

Setting

This study was conducted through over-the-phone interviews to participants that presented to 300 primary care clinics with a new episode of acute low back pain.

Participants

This study included 999 consecutive patients, aged 18 years or older. Follow-up assessment was completed at 12 months following the index episode.

Methods

This is a cohort study where consecutive patients, aged 18 years or older, that presented with a new episode of acute low back pain were recruited between October 2011 and November 2012.

Main outcome measurements

Self-reported level of physical activity participation.

Results

A total of 830 participants completed the study. When comparing participants who reported pain at 12 months follow-up with those without pain, all participants reported similar levels of physical activity participation one week before (p = 0.449), one week after (p = 0.812) and 12 months after the index episode (p = 0.233). The level of physical activity participation before the index episode was not a reliable predictor of presence of pain at either 3 or 12 months follow-up (OR 0.99; 95% CI 0.993 to 1.003; p = 0.523 and OR 1; 95% CI 0.992 to 1.008; p = 0.923, respectively).

Conclusion

Physical activity participation did not predict recovery from the pain episode. Also all participants returned to their pre-pain level of physical activity participation after 12 months.

Preliminary evidence for physical activity following pelvic exenteration: a pilot longitudinal cohort study

Background

The physical activity (PA) level of patients undergoing major cancer surgery remains unclear. This pilot study aimed to: (i) Compare preoperative PA level between patients undergoing major cancer surgery and the general population; (ii) describe PA trajectories following major cancer surgery; (iii) Compare objective versus subjective PA measures in patients undergoing major cancer surgery; and (iv) Investigate the association between preoperative PA level and postoperative outcomes.

Methods

Patients undergoing pelvic exenteration between September/2016 and September/2017 were included and followed at preoperative, 6-weeks and 6-months postoperative. PA was measured using the International Physical Activity Questionnaire Short-Form and McRoberts activity monitor. Analyses were performed using SPSS.

Results

This pilot study included 16 patients. When compared to the general population, patients undergoing major cancer surgery presented a reduced preoperative PA level. PA levels decreased at 6 weeks but returned to preoperative levels at 6 months postoperative. Objective and subjective measures of PA were comparable, with some variables presenting strong correlations. A higher preoperative level PA was associated with an absence of postoperative complications and better quality of life outcomes.

Conclusions

Patients undergoing major cancer surgery demonstrated lower PA levels when compared to the general population. PA trajectories decreased at 6 weeks postoperative, returning to preoperative levels within 6-months. In this cohort, it seems that higher preoperative PA level may improve postoperative surgical outcomes; however, this preliminary evidence should be confirmed in a larger cohort.

Comparative efficacy and safety of surgical and invasive treatments for adults with degenerative lumbar spinal stenosis: protocol for a network meta-analysis and systematic review

INTRODUCTION

Surgical and invasive procedures are widely used in adults with degenerative lumbar spinal stenosis when conservative treatments fail. However, little is known about the comparative efficacy and safety of these interventions. To address this, we will perform a network meta-analysis (NMA) and systematic review to compare the efficacy and safety of surgical and invasive procedures for adults with degenerative lumbar spinal stenosis.

METHODS AND ANALYSIS

We will include randomised controlled trials assessing surgical and invasive treatments for adults with degenerative lumbar spinal stenosis. We will search AMED, CINAHL, EMBASE, the Cochrane Library and MEDLINE. Only English studies will be included and no restriction will be set for publication status. For efficacy, our primary outcome will be physical function. Secondary outcomes will include pain intensity, health-related quality of life, global impression of recovery, work absenteeism and mobility. For safety, our primary outcome will be all-cause mortality. Secondary outcomes will include adverse events (number of events or number of people with an event) and treatment withdrawal due to adverse effect. Two reviewers will independently select studies, extract data and assess the risk of bias (Revised Cochrane risk-of-bias tool for randomized trials) of included studies. The quality of the evidence will be evaluated through the Grading of Recommendations Assessment, Development and Evaluation framework. Random-effects NMA will be performed to combine all the evidence under the frequentist framework and the ranking results will be presented through the surface under the cumulative ranking curve and mean rank. All analyses will be performed in Stata and R.

ETHICS AND DISSEMINATION

No ethical approval is required. The research will be published in a peer-reviewed journal.

The influence of kinesiology tape colour on performance and corticomotor activity in healthy adults: a randomised crossover controlled trial

Background

There exists conflicting evidence regarding the impact of kinesiology tape on performance and muscle function. One variable that may account for disparities in the findings of previous studies is the colour of the tape applied. Colour is hypothesised to influence sporting performance through modulation of arousal and aggression. However, few studies have investigated the influence of colour on products designed specifically to enhance athletic performance. Further, no studies have investigated the potential influence of colour on other drivers of performance, such as corticomotor activity and neuromuscular function. Thus, the aim of this study was to investigate the influence of kinesiology tape colour on athletic performance, knee extensor torque, and quadriceps neuromuscular function.

Methods

Thirty two healthy participants were assessed under five conditions, applied in random order: (1) no kinesiology tape (control), (2) beige-coloured kinesiology tape applied with tension (sham A), (3) beige-coloured kinesiology tape applied with no tension (sham B), (4) red-coloured kinesiology tape applied with tension, and (5) blue-coloured kinesiology tape applied with tension. Athletic performance was assessed using a previously validated hop test, knee extensor torque was measured using an isokinetic dynamometer, and transcranial magnetic stimulation was utilised to provide insight into the neuromuscular functioning of the quadriceps musculature.

Results

Kinesiology tape had no beneficial impact on lower limb performance or muscle strength in healthy adults. The colour of the tape did not influence athletic performance (F (4, 120) = 0.593, p = 0.669), quadriceps strength (F (4, 120) = 0.787, p = 0.536), or neuromuscular function (rectus femoris: F (2.661, 79.827) = 1.237, p = 0.301).

Conclusion

This study found that kinesiology tape does not alter lower limb performance or muscle function in healthy adults, irrespective of the colour of the tape applied. Future research should seek to confirm these findings beyond the research setting, across a range of sports, and at a range of skill levels.

Is preoperative physical activity level of patients undergoing cancer surgery associated with postoperative outcomes? A systematic review and meta-analysis

BACKGROUND

There is uncertainty about the role of preoperative physical activity (PA) level and its influence on postoperative outcomes, especially for patients undergoing cancer surgery.

AIM

To investigate if the level of preoperative PA in patients undergoing cancer surgery is associated with postoperative complication rates, length of hospital stay (LOS) and quality of life (QOL).

METHODS

An electronic search was performed from inception to 26th November 2017 in MEDLINE, Embase, AMED and CINAHL. Studies investigating the association between objective or subjective level of PA and postoperative complication rates, LOS and QOL were included. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool. When possible, summary odds ratios (OR) and 95% confidence intervals (CI) were calculated using random-effect models.

RESULTS

13 studies (5523 unique patients) were included. Overall, most studies were rated as having low or moderate risk of bias. Higher preoperative level of PA was not significantly associated with absence of postoperative complications (OR = 2.60; 95%CI = 0.59 to 11.37) but was significantly associated with shorter LOS (OR = 3.66; 95%CI = 1.38 to 9.6) and postoperative QOL (OR = 1.29; 95%CI = 1.11 to 1.49).

CONCLUSIONS

The available literature suggests higher levels of preoperative PA in patients undergoing cancer surgery may be associated with better postoperative outcomes, particularly shorter LOS and better QOL. There is a need for high-quality studies investigating the association between preoperative PA and postoperative outcomes.

Feasibility and acceptability of PrE-operative Physical Activity to improve patient outcomes After major cancer surgery: study protocol for a pilot randomised controlled trial (PEPA Trial)

BACKGROUND

There is a need for evidence of the effectiveness of pre-operative exercise for patients undergoing major cancer surgery; however, recruitment to such trials can be challenging. The PrE-operative Physical Activity (PEPA) Trial will establish the feasibility and acceptability of a pre-operative exercise programme aimed to improve patient outcomes after cytoreductive surgery and pelvic exenteration. The secondary aim is to obtain pilot data on the likely difference in key outcomes (post-operative complications, length of hospital stay, post-operative functional capacity and quality of life) to inform the sample size calculation for the substantive randomised clinical trial.

METHODS/DESIGN

Twenty patients undergoing cytoreductive surgery and pelvic exenteration at the Royal Prince Alfred Hospital, Sydney will be recruited and randomly allocated (1:1 ratio) to either 2 to 6 weeks' pre-operative exercise programme (intervention group) or usual care (control group). Those randomised to the intervention group will receive up to six individualised, 1-h physiotherapy sessions (including aerobic and endurance exercises, respiratory muscle exercises, stretching and flexibility exercises), home exercises (instruction and recommendations on how to progress the exercises at home) and encouragement to be more active by using an activity tracker to measure the number of steps walked daily. Patients allocated to the control group will not receive any specific advice about exercise training. Feasibility will be assessed with consent rates to the study, and for the intervention group, retention and adherence rates to the exercise programme. Acceptability of the exercise programme will be assessed with a semi-structured questionnaire. The following measures of the effectiveness of the intervention will be collected at baseline (2 to 6 weeks pre-operative), a week before surgery, during hospital stay and pre hospital discharge: post-operative complication rates (Clavien-Dindo), post-operative functional capacity (Six-minute Walk Test) and quality of life (SF-36v2®) and length of hospital stay. Functional status will be additionally measured using Cardiopulmonary Exercise Testing (CPET), at baseline and within a week before surgery.

DISCUSSION

The PEPA Trial will provide important information about the feasibility and acceptability of a pre-operative exercise programme for patients undergoing major cancer surgery. Data from the PEPA Trial will be used to inform the design, methodology and to calculate sample size required for a larger, definitive trial.

Preoperative exercise halves the postoperative complication rate in patients with lung cancer: a systematic review of the effect of exercise on complications, length of stay and quality of life in patients with cancer

Objective

To investigate the effectiveness of preoperative exercises interventions in patients undergoing oncological surgery, on postoperative complications, length of hospital stay and quality of life.

Design

Intervention systematic review with meta-analysis.

Data sources

MEDLINE, Embase and PEDro.

Eligibility criteria for selecting studies

Trials investigating the effectiveness of preoperative exercise for any oncological patient undergoing surgery were included. The outcomes of interest were postoperative complications, length of hospital stay and quality of life. Relative risks (RRs), mean differences (MDs) and 95% CI were calculated using random-effects models.

Results

Seventeen articles (reporting on 13 different trials) involving 806 individual participants and 6 tumour types were included. There was moderate-quality evidence that preoperative exercise significantly reduced postoperative complication rates (RR 0.52, 95% CI 0.36 to 0.74) and length of hospital stay (MD −2.86 days, 95% CI −5.40 to −0.33) in patients undergoing lung resection, compared with control. For patients with oesophageal cancer, preoperative exercise was not effective in reducing length of hospital stay (MD 2.00 days, 95% CI −2.35 to 6.35). Although only assessed in individual studies, preoperative exercise improved postoperative quality of life in patients with oral or prostate cancer. No effect was found in patients with colon and colorectal liver metastases.

Conclusions

Preoperative exercise was effective in reducing postoperative complications and length of hospital stay in patients with lung cancer. Whether preoperative exercise reduces complications, length of hospital stay and improves quality of life in other groups of patients undergoing oncological surgery is uncertain as the quality of evidence is low.

Diagnostic accuracy of the Ottawa Ankle and Midfoot Rules: a systematic review with meta-analysis

OBJECTIVE

To review the diagnostic accuracy of the Ottawa Ankle and Midfoot Rules and explore if clinical features and/or methodological quality of the study influence diagnostic accuracy estimates.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, SPORTDiscus and Cochrane Library.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Primary diagnostic studies reporting the accuracy of the Rules in people with ankle and/or midfoot injury were retrieved. Diagnostic accuracy estimates, overall and for subgroups (patient's age, profession of the assessor and setting of application), were made. Sensitivity analyses included studies with a low risk of bias and studies where all patients received radiographs.

RESULTS

66 studies were included. Ankle and Midfoot Rules presented similar accuracies, which were homogeneous and high for sensitivity and negative likelihood ratios and poor and heterogeneous for specificity and positive likelihood ratios (mean, 95% CI pooled sensitivity of Ankle Rules: 99.4%, 97.9% to 99.8%; specificity: 35.3%, 28.8% to 42.3%). Sensitivity of the Ankle Rules was higher in adults than in children, but the profession of the assessor did not appear to influence accuracy. Specificity was higher for Midfoot than for Ankle Rules. There were not enough studies to allow comparison according to setting of application. Studies with a low risk of bias and where all patients received radiographs provided lower accuracy estimates. Specificity heterogeneity was not explained by assessor training, use of imaging in all patients and low risk of bias.

CONCLUSIONS

Study features and the methodological quality influence estimates of the diagnostic accuracy of the Ottawa Ankle and Midfoot Rules.

Rehabilitation After Immobilization for Ankle Fracture: The EXACT Randomized Clinical Trial

IMPORTANCE

The benefits of rehabilitation after immobilization for ankle fracture are unclear.

OBJECTIVES

To determine the effectiveness of a supervised exercise program and advice (rehabilitation) compared with advice alone and to determine if effects are moderated by fracture severity or age and sex.

DESIGN, SETTING, AND PARTICIPANTS

The EXACT trial was a pragmatic, randomized clinical trial conducted from December 2010 to June 2014. Patients with isolated ankle fracture presenting to fracture clinics in 7 Australian hospitals were randomized on the day of removal of immobilization. Of 571 eligible patients, 357 chose not to participate and 214 were allocated to rehabilitation (n = 106) or advice alone (n = 108), with 194 (91%) followed up at 1 month, 173 (81%) at 3 months, and 170 (79%) at 6 months. There were no withdrawals attributed to adverse effects. Recruitment terminated early on December 31, 2013 (planned enrollment, 342; actual, 214), because funding was exhausted.

INTERVENTIONS

Supervised exercise program and advice about self-management (rehabilitation) (individually tailored, prescribed, monitored, and progressed) or advice alone, both delivered by a physical therapist.

MAIN OUTCOMES AND MEASURES

Primary outcomes were activity limitation assessed using the Lower Extremity Functional Scale (score range, 0-80; higher scores indicate better activity), and quality of life assessed using the Assessment of Quality of Life (score range, 0-1; higher scores indicate better quality of life), measured at baseline and at 1, 3 (primary time point), and 6 months.

RESULTS

Mean activity limitation and quality of life at baseline were 30.1 (SD, 12.5) and 0.51 (SD, 0.24), respectively, for advice and 30.2 (SD, 13.2) and 0.54 (SD, 0.24) for rehabilitation, increasing to 64.3 (SD, 13.5) and 0.85 (SD, 0.17) for advice vs 64.3 (SD, 15.1) and 0.85 (SD, 0.20) for rehabilitation at 3 months. Rehabilitation was not more effective than advice for activity limitation (mean effect at 3 months, 0.4 [95% CI, -3.3 to 4.1]) or quality of life (-0.01 [95% CI, -0.06 to 0.04]). Treatment effects were not moderated by fracture severity or age and sex.

CONCLUSIONS AND RELEVANCE

A supervised exercise program and advice did not confer additional benefits in activity limitation or quality of life compared with advice alone for patients with isolated and uncomplicated ankle fracture. These findings do not support the routine use of supervised exercise programs after removal of immobilization for patients with isolated and uncomplicated ankle fracture.

Communication that values patient autonomy is associated with satisfaction with care: a systematic review

QUESTION

Which communication factors used by clinicians during patient-clinician interactions are associated with satisfaction with care?

DESIGN

Systematic review with meta-analysis of studies investigating the association of verbal or nonverbal factors or interaction styles used by clinicians with patient satisfaction during an encounter between clinician and patient.

PARTICIPANTS

: Clinicians interacting with patients in primary care or rehabilitation settings.

RESULTS

Twenty seven studies investigated 129 verbal, nonverbal, and interaction style factors. Of these, 38 factors were consistently associated with satisfaction. Verbal factors concerning clinicians involving, facilitating, and supporting patients were associated with satisfaction with care. Most communication factors presented a fair correlation (r≥0.21 but <0.41) with satisfaction with care. Nonverbal factors such as time spent discussing prevention and time spent reading patient charts had a fair association with satisfaction with care (correlations range from 0.21 to 0.40). A moderate association was found between interaction styles such as caring (pooled r=0.51, 95% CI 0.42 to 0.60) and satisfaction with care. Over half (58%) of the 129 identified factors never associated with satisfaction with care and the remainder associated inconsistently.

CONCLUSION

The number of potential modifiable communication factors associated with satisfaction with care and the magnitude of their association partially support interventions to train clinicians in communication skills that value patient autonomy.

Rehabilitation for ankle fractures in adults

BACKGROUND

Rehabilitation after ankle fracture can begin soon after the fracture has been treated, either surgically or non-surgically, by the use of different types of immobilisation that allow early commencement of weight-bearing or exercise. Alternatively, rehabilitation, including the use of physical or manual therapies, may start following the period of immobilisation. This is an update of a Cochrane review first published in 2008.

OBJECTIVES

To assess the effects of rehabilitation interventions following conservative or surgical treatment of ankle fractures in adults.

SEARCH METHODS

We searched the Specialised Registers of the Cochrane Bone, Joint and Muscle Trauma Group and the Cochrane Rehabilitation and Related Therapies Field, CENTRAL via The Cochrane Library (2011 Issue 7), MEDLINE via PubMed, EMBASE, CINAHL, PEDro, AMED, SPORTDiscus and clinical trials registers up to July 2011. In addition, we searched reference lists of included studies and relevant systematic reviews.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials with adults undergoing any interventions for rehabilitation after ankle fracture were considered. The primary outcome was activity limitation. Secondary outcomes included quality of life, patient satisfaction, impairments and adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, assessed risk of bias and extracted data. Risk ratios and 95% confidence intervals (95% CIs) were calculated for dichotomous variables, and mean differences or standardised mean differences and 95% CIs were calculated for continuous variables. End of treatment and end of follow-up data were presented separately. For end of follow-up data, short term follow-up was defined as up to three months after randomisation, and long-term follow-up as greater than six months after randomisation. Meta-analysis was performed where appropriate.

MAIN RESULTS

Thirty-eight studies with a total of 1896 participants were included. Only one study was judged at low risk of bias. Eight studies were judged at high risk of selection bias because of lack of allocation concealment and over half the of the studies were at high risk of selective reporting bias.Three small studies investigated rehabilitation interventions during the immobilisation period after conservative orthopaedic management. There was limited evidence from two studies (106 participants in total) of short-term benefit of using an air-stirrup versus an orthosis or a walking cast. One study (12 participants) found 12 weeks of hypnosis did not reduce activity or improve other outcomes.Thirty studies investigated rehabilitation interventions during the immobilisation period after surgical fixation. In 10 studies, the use of a removable type of immobilisation combined with exercise was compared with cast immobilisation alone. Using a removable type of immobilisation to enable controlled exercise significantly reduced activity limitation in five of the eight studies reporting this outcome, reduced pain (number of participants with pain at the long term follow-up: 10/35 versus 25/34; risk ratio (RR) 0.39, 95% confidence interval (CI) 0.22 to 0.68; 2 studies) and improved ankle dorsiflexion range of motion. However, it also led to a higher rate of mainly minor adverse events (49/201 versus 20/197; RR 2.30, 95% CI 1.49 to 3.56; 7 studies).During the immobilisation period after surgical fixation, commencing weight-bearing made a small improvement in ankle dorsiflexion range of motion (mean difference in the difference in range of motion compared with the non-fractured side at the long term follow-up 6.17%, 95% CI 0.14 to 12.20; 2 studies). Evidence from one small but potentially biased study (60 participants) showed that neurostimulation, an electrotherapy modality, may be beneficial in the short-term. There was little and inconclusive evidence on what type of support or immobilisation was the best. One study found no immobilisation improved ankle dorsiflexion and plantarflexion range of motion compared with cast immobilisation, but another showed using a backslab improved ankle dorsiflexion range of motion compared with using a bandage.Five studies investigated different rehabilitation interventions following the immobilisation period after either conservative or surgical orthopaedic management. There was no evidence of effect for stretching or manual therapy in addition to exercise, or exercise compared with usual care. One small study (14 participants) at a high risk of bias found reduced ankle swelling after non-thermal compared with thermal pulsed shortwave diathermy.

AUTHORS' CONCLUSIONS

There is limited evidence supporting early commencement of weight-bearing and the use of a removable type of immobilisation to allow exercise during the immobilisation period after surgical fixation. Because of the potential increased risk of adverse events, the patient's ability to comply with the use of a removable type of immobilisation to enable controlled exercise is essential. There is little evidence for rehabilitation interventions during the immobilisation period after conservative orthopaedic management and no evidence for stretching, manual therapy or exercise compared to usual care following the immobilisation period. Small, single studies showed that some electrotherapy modalities may be beneficial. More clinical trials that are well-designed and adequately-powered are required to strengthen current evidence.

EXACT: exercise or advice after ankle fracture. Design of a randomised controlled trial

Background

Ankle fractures are common. Management of ankle fractures generally involves a period of immobilisation followed by rehabilitation to reduce pain, stiffness, weakness and swelling. The effects of a rehabilitation program are still unclear. However, it has been shown that important components of rehabilitation programs may not confer additional benefits over exercise alone. The primary aim of this trial is to determine the effectiveness and cost-effectiveness of an exercise-based rehabilitation program after ankle fracture, compared to advice alone.

Methods/Design

A pragmatic randomised trial will be conducted. Participants will be 342 adults with stiff, painful ankles after ankle fracture treated with immobilisation. They will be randomly allocated using a concealed randomisation procedure to either an Advice or Rehabilitation group. Participants in the Advice group will receive verbal and written advice about exercise at the time of removal of immobilisation. Participants in the Rehabilitation group will be provided with a 4-week rehabilitation program that is designed, monitored and progressed by a physiotherapist, in addition to verbal and written advice. Outcomes will be measured by a blinded assessor at 1, 3 and 6 months. The primary outcomes will be activity limitation and quality-adjusted life years.

Discussion

This pragmatic trial will determine if a rehabilitation program reduces activity limitation and improves quality of life, compared to advice alone, after immobilisation for ankle fracture.
