Surgical interventions for degenerative lumbar spinal stenosis: a systematic review with network meta-analysis.

BACKGROUND: Several surgical options for degenerative lumbar spinal stenosis (LSS) are available, but current guidelines do not recommend which one should be prioritized. Although previous network meta-analyses (NMAs) have been performed on this topic, they have major methodological problems and could not provide the convincing evidence and clinical practical information required. METHODS: Randomized controlled trials (RCTs) comparing at least two surgical interventions were included by searching AMED, CINAHL, EMBASE, the Cochrane Library, and MEDLINE (inception to August 2023). A frequentist random-effects NMA was performed for physical function and adverse events due to any reason. For physical function, three follow-up time points were included: short-term (< 6 months post-intervention), mid-term (≥ 6 months but < 12 months), and long-term (≥ 12 months). Laminectomy was the reference comparison intervention. RESULTS: A total of 43 RCTs involving 5017 participants were included in the systematic review and 28 RCTs encompassing 14 types of surgical interventions were included in the NMA. For improving physical function (scale 0-100), endoscopic-assisted laminotomy (mean difference: - 8.61, 95% confidence interval: - 10.52 to - 6.69; moderate-quality evidence), laminectomy combined with Coflex (- 8.41, - 13.21 to - 3.61; moderate quality evidence), and X-stop (- 6.65, - 8.60 to - 4.71; low-quality evidence) had small effects at short-term follow-up; no statistical difference was observed at mid-term follow-up (very low- to low-quality evidence); at long-term follow-up, endoscopic-assisted laminotomy (- 7.02, - 12.95 to - 1.08; very low-quality evidence) and X-stop (- 10.04, - 18.16 to - 1.93; very low-quality evidence) had a small and moderate effect, respectively. Compared with laminectomy, endoscopic-assisted laminotomy was associated with fewer adverse events due to any reason (odds ratio: 0.27, 0.09 to 0.86; low-quality evidence). CONCLUSIONS: For adults with degenerative LSS, endoscopic-assisted laminotomy may be the safest and most effective intervention in improving physical function. However, the available data were insufficient to indicate whether the effect was sustainable after 6 months. TRIAL REGISTRATION: PROSPERO (CRD42018094180).

Attitudes and practices of Australian healthcare and sports workers on the use of ankle supports for management and prevention of lateral ankle sprains: A cross-sectional survey.

OBJECTIVE: Explore attitudes and practices of Australian professionals using ankle taping or bracing for the management and prevention of lateral ankle sprains. DESIGN: Cross-sectional study. SETTING: Anonymous online survey. PARTICIPANTS: Australian healthcare or athletic workers, registered with an official governing body, involved in the management and/or prevention of lateral ankle sprains. MAIN OUTCOME MEASURES: Quantitative data was collected from 20 close-ended questions. Qualitative data from 14 open-ended questions were categorized into topics using inductive thematic analysis. Data was analysed using descriptive statistics and presented in figures and tabular format. RESULTS: A total 160 respondents answered the survey; the majority were podiatrists (42.5%), physiotherapists (23%), or sports/athletic trainers (13.8%). Ankle supports were overwhelmingly recommended and considered to be effective in the management (95% and 89% bracing and taping, respectively) and prevention (96% and 92% bracing and taping, respectively) of lateral ankle sprains. For management, semi-rigid brace with straps (26%) and figure eight taping technique (42%) were the most frequently used. For prevention, the most commonly used were soft brace with straps (30%) and the figure eight taping technique (37%). CONCLUSIONS: Australian professionals expressed a positive attitude towards using ankle supports in the management and prevention of lateral ankle sprains.

A community health-coaching referral program following discharge from treatment for chronic low back pain - a qualitative study of the patient's perspective.

BACKGROUND: Global policy and guidelines for low back pain (LBP) management promote physical activity and self-management yet adherence is poor and a decline in outcomes is common following discharge from treatment. Health coaching is effective at improving exercise adherence, self-efficacy, and social support in individuals with chronic conditions, and may be an acceptable, cost-effective way to support people in the community following discharge from treatment for LBP. AIM: This qualitative study aimed to understand which aspects of a community over-the-phone health-coaching program, were liked and disliked by patients as well as their perceived outcomes of the service after being discharged from LBP treatment. METHODS: A purposive sampling approach was used to recruit 12 participants with chronic LBP, from a large randomised controlled trial, who were randomly allocated to receive a health coaching program from the Get Healthy Service® in Australia. Semi-structured interviews were conducted, and a general inductive thematic analysis approach was taken. RESULTS: The main themes uncovered regarding the intervention included the positive and negative aspects of the health coaching service and the relationship between the participant and health coach. Specifically, the participants spoke of the importance of the health coach, the value of goal setting, the quality of the advice received, the benefits of feeling supported, the format of the coaching service, and LBP-specific knowledge. They also reported the health coach and the coaching relationship to be the primary factors influencing the program outcomes and the qualities of the coaching relationship they valued most were connection, communication, care, and competence. The sub-themes uncovered regarding the outcomes of the intervention included positive impacts (a greater capacity to cope, increased confidence, increased motivation and increased satisfaction) and negative impacts (receiving no personal benefit). CLINICAL IMPLICATIONS: In an environment where self-management and self-care are becoming increasingly important, understanding the patient's experience as part of a coaching program is likely to lead to improved quality of health coaching care, more tailored service delivery and potentially more effective and cost-effective community-based care for individuals with chronic LBP in the community after being discharged from treatment. TRIAL REGISTRATION: The GBTH trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000889954) on 10/9/2020. Ethical approval was prospectively granted by the Western Sydney Local Health District Human Research and Ethics Committee (2020/ETH00115). Written informed consent was obtained from all participants. The relevant sponsor has reviewed the study protocol and consent form.

Rehabilitation for ankle fractures in adults.

BACKGROUND: Ankle fracture is one of the most common lower limb fractures. Whilst immobilisation of the ankle can support and protect the fracture site during early healing, this also increases the risk of ankle weakness, stiffness, and residual pain. Rehabilitation aims to address the after-effects of this injury, to improve ankle function and quality of life. Approaches are wide-ranging and include strategies to improve ankle joint movement, muscle strength, or both. This is an update of a Cochrane review last published in 2012. OBJECTIVES: To assess the effects of rehabilitation interventions following surgical or non-surgical management of ankle fractures in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, three other databases, and two clinical trials registers in May 2022, and conducted additional searches of CENTRAL, MEDLINE, and Embase in March 2023. We also searched reference lists of included studies and relevant systematic reviews. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs comparing any rehabilitation intervention delivered to adults with ankle fracture. Interventions could have been given during or after the initial fracture management period (typically the first six weeks after injury), which may or may not have included surgical fixation. We excluded participants with multi-trauma, pathological fracture, or with established complications secondary to ankle fracture. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We collected data for five outcomes: activity limitation (ankle function), health-related quality of life (HRQoL), participant satisfaction with treatment, pain, and adverse events (we focused on re-operation, defined as unplanned return to theatre). We report the findings up to six months after injury. MAIN RESULTS: We included 53 studies (45 RCTs, 8 quasi-RCTs) with 4489 adults with ankle fracture. In most studies, orthopaedic management included surgical fixation but was non-surgical in five studies, and either surgical or non-surgical in six studies. Here, we summarise the findings for three common rehabilitation comparisons; these included the most data and were the most clinically relevant. Because of different intervention approaches, we sometimes included a study in more than one comparison. Data for other less common comparisons were also available but often included few participants and were imprecise. All studies were unavoidably at high risk of performance and detection bias. We downgraded the certainty of all evidence for this reason. We also downgraded for imprecision and when we noted inconsistencies between studies that precluded meta-analysis of data. Early (within 3 weeks of surgery) versus delayed weight-bearing (12 studies, 1403 participants) Early weight-bearing probably leads to better ankle function (mean difference (MD) 3.56, 95% confidence interval (CI) 1.35 to 5.78; 5 studies, 890 participants; moderate-certainty evidence); however, this does not include a clinically meaningful difference. Early weight-bearing may offer little or no difference to HRQoL compared to delayed weight-bearing (standardised mean difference (SMD) 0.15, 95% CI -0.01 to 0.30; 5 studies, 739 participants; low-certainty evidence); when translated to the EQ-5D scale (a commonly-used HRQoL questionnaire), any small difference was not clinically important. We were unsure whether there were any differences in participant satisfaction or pain because these outcomes had very low-certainty evidence. For adverse events, there may be little or no difference in re-operation (risk ratio (RR) 0.50, 95% CI 0.09 to 2.68; 7 studies, 1007 participants; low-certainty evidence). Removable versus non-removable ankle support (25 studies, 2206 participants) Following surgery, using a removable ankle support may lead to better ankle function (MD 6.39, 95% CI 1.69 to 11.09; 6 studies, 677 participants; low-certainty evidence). This effect included both a clinically important and unimportant difference. There is probably an improvement in HRQoL with a removable ankle support, although this difference included both a clinically important and unimportant difference when translated to the EQ-5D scale (SMD 0.30, 95% CI 0.11 to 0.50; 3 studies, 477 participants; moderate-certainty evidence). No studies reported participant satisfaction. We were unsure of the effects on pain because of very low-certainty evidence (1 study, 29 participants). There may be little or no difference in re-operations (RR 1.20, 95% CI 0.39 to 3.71; 6 studies, 624 participants; low-certainty evidence). Following non-surgical management, there may be little or no difference between removable and non-removable ankle supports in ankle function (MD 1.08, 95% CI -3.18 to 5.34; 3 studies, 399 participants), and HRQoL (SMD -0.04, 95% CI -0.24 to 0.15; 3 studies, 397 participants); low-certainty evidence. No studies reported participant satisfaction. We were unsure of the effects on pain (2 studies, 167 participants), or re-operation because of very low-certainty evidence (1 study, 305 participants). Physical therapy interventions versus usual care or other physical therapy interventions (9 studies, 857 participants) Types of interventions included the use of active controlled motion, a spring-loaded ankle trainer, an antigravity treadmill, and variations of enhanced physiotherapy (e.g. additional stretching, joint mobilisation, neuromuscular exercises), delivered during or after the initial fracture management period. We were unable to pool data because of the differences in the design of interventions and their usual care comparators. Studies often included very few participants. The certainty of the evidence for all outcomes in this comparison was very low, and therefore we were unsure of the effectiveness of these therapies. No studies in this comparison reported re-operation. AUTHORS' CONCLUSIONS: Early weight-bearing may improve outcomes in the first six months after surgery for ankle fracture, but the difference is likely to be small and may not always be clinically important. A removable ankle support may also provide a better outcome, but again, the difference may not always be clinically important. It is likely that neither approach increases the re-operation risk. We assume that the findings for these comparisons are applicable to people with closed ankle fractures, and that satisfactory fracture stabilisation had been achieved with surgery. For people who have non-surgical treatment, there is no evidence that either a removable or non-removable ankle support may be superior. We were uncertain whether any physical therapy interventions were more effective than usual care or other physical therapy interventions. We encourage investigators of future studies on rehabilitation interventions for ankle fracture to use a core outcome set.

Global prevalence of musculoskeletal pain in rural and urban populations. A systematic review with meta-analysis. Musculoskeletal pain in rural and urban populations.

INTRODUCTION: To systematically compare the global prevalence of musculoskeletal pain and care-seeking in rural and urban populations. METHODS: A systematic review with meta-analysis of observational studies reporting a direct comparison of rural and urban populations was conducted worldwide and included back, knee, hip, shoulder, neck pain and a broad diagnosis of 'musculoskeletal pain'. A search strategy combining terms related to 'prevalence', 'musculoskeletal pain' and 'rural' was used on the following databases: MEDLINE, Embase, CINAHL, Scopus, and rural and remote health from their inception to 1 June 2022. Random-effects meta-analysis was used to pool the data. Results were presented as odds ratios (OR) along with 95% confidence intervals (95% CI). RESULTS: A total of 42 studies from 24 countries were included with a total population of 489 439 participants. The quality scores for the included studies, using the modified Newcastle Ottawa Scale tool, showed an average score of 0.78/1, which represents an overall good quality. The pooled analysis showed statistically greater odds of hip (OR = 1.62, 95% CI = 1.23-2.15), shoulder (OR = 1.42, 95% CI = 1.06-1.90) and overall musculoskeletal pain (OR = 1.26, 95% CI = 1.08-1.47) in rural populations compared to urban populations. Although the odds of seeking treatment were higher in rural populations this relationship was not statistically significant (OR = 0.76, 95% CI = 0.55-1.03). CONCLUSION: Very low-certainty evidence suggests that musculoskeletal, hip and shoulder pain are more prevalent in rural than urban areas, although neck, back and knee pain, along with care-seeking, showed no significant difference between these populations. Strategies aimed to reduce the burden of musculoskeletal pain should consider the specific needs and limited access to quality evidence-based care for musculoskeletal pain of rural populations.

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.

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.

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.

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.

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.

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.

Effect of Braces on Performance in the Context of Chronic Ankle Instability.

Ankle braces are commonly recommended for prevention of ankle sprains, especially secondary sprains, rehabilitation, and return to normal activity or sport after injury. One common resistance to use is the feeling that braces will impede functional performance. For people with chronic ankle instability, the limited research indicates that the use of semirigid, lace-up, or soft-shell braces will not affect, and in some cases, may enhance performance. Activities that could be enhanced are jumping, hopping, and dynamic balance.

(C)onsumer focused (E)ducation on p(A)racetamol (S)ide (E)ffects, i(N)adequate (O)utcomes and (W)eaning (CEASE NOW) for individuals with low back pain: results of a feasibility study.

OBJECTIVES: To determine the feasibility of a patient-education booklet to support patients with low back pain (LBP) to reduce paracetamol intake. DESIGN: Single group, repeated measures feasibility study. SETTING: Community. PARTICIPANTS: Adults experiencing LBP of any kind and self-reporting consumption of paracetamol for LBP weekly for at least 1 month were invited to participate. INTERVENTION: Participants received a patient-education booklet 1 week after the baseline measures were collected. The intervention was designed to change beliefs, increase knowledge and self-efficacy to deprescribe paracetamol for their LBP and create discussion with a health professional through the mechanisms of motivation, capacity and opportunity. PRIMARY OUTCOME MEASURES: Feasibility of recruitment procedures, data collection and acceptability of the intervention. SECONDARY OUTCOME MEASURES: Changes in motivation, self-efficacy, opportunity to deprescribe paracetamol for their LBP, paracetamol usage and LBP clinical outcomes at baseline, 1-week and 1-month follow-up. RESULTS: A total of 24 participants were recruited into the study within the timeframe of 3 months from study advertisement and all completed the study follow-up. There were no missing data for any outcome measure across all follow-up points, 22 (91.6%) participants were willing to participate in a future randomised control trial (RCT) and over 60% of participants responded positively to questions regarding acceptability of the patient-educational booklet. Overall, at the 1-month follow-up, approximately two thirds (15/24) of participants had an increase in motivation and self-efficacy scores and had discussed or intended to discuss their paracetamol use for LBP with a health professional. CONCLUSIONS: The results of this study demonstrate that the patient-education booklet is feasible to implement, and both the intervention and study design were well-received by participants. This study supports the undertaking an RCT to assess the effects of the patient-education booklet on deprescribing paracetamol in people with LBP.

The impact of different intensities and domains of physical activity on analgesic use and activity limitation in people with low back pain: A prospective cohort study with a one-year followup.

BACKGROUND: Analgesics are the most common form of managing low back pain (LBP). No previous study has examined which domains and intensities of physical activity are most beneficial in reducing the frequency of analgesic use for LBP and its related activity limitation. METHODS: This cohort study forms part of the AUstralian Twin low BACK pain study, investigating the impact of physical activity on LBP. Information on demographics, LBP and health-related factors, including physical activity, were collected at baseline. Data on the total counts of analgesic use and activity limitation for LBP were collected weekly for one-year. Negative binomial regression models were conducted separately for each type of physical activity. Results were presented as incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS: From an initial sample of 366 participants, 86 participants reported counts of analgesic use and 140 recorded counts of activity limitation across the follow-up period. The negative binomial regression models for analgesic use counts indicated that engagement in moderate-vigorous physical activity was protective for use of analgesics (IRR 0.97, 95% CI 0.96-0.99), while physical workload was associated with greater use (IRR 1.02, 95% CI 1.01-1.05). No other significant relationships were observed for the other measures of physical activity. For activity limitation counts, engagement in leisure activity was associated with less counts of activity limitation (IRR 0.94, 95% CI 0.81-0.99), while greater amounts of sedentary time was associated with higher counts (IRR 1.04, 95% CI 1.01-1.09). No other significant relationships were observed for the other measures of physical activity. CONCLUSIONS: Our findings highlight the potential importance of supporting engagement in moderate-vigorous and leisure physical activity as well as minimizing sedentary time and physical workload to reduce the risk of activity limitation and the need for analgesic use in people with LBP. SIGNIFICANCE: We examined which domains and intensities of physical activity are most beneficial in reducing the frequency of analgesic use for low back pain and its related activity limitation. Engaging in moderate-vigorous and leisure physical activity as well as minimizing sedentary time and physical workload has the potential to reduce the risk of activity limitation and the need for analgesic use in people with low back pain.

The effect of ankle supports on lower limb biomechanics during functional tasks: A systematic review with meta-analysis.

OBJECTIVES: To systematically review the literature on the effects of ankle supports on lower extremity biomechanics during functional tasks. DESIGN: Systematic review with meta-analysis. METHODS: Eight electronic databases were searched from inception to July 2019. Studies of biomechanical outcomes during functional tasks that used a within-participant (repeated measures) design were included. Two independent reviewers screened studies, extracted data, assessed the methodological quality of the included studies and rated the quality of evidence. Meta-analysis was performed and reported as standardised mean differences and 95% confidence intervals. RESULTS: A total of 8350 studies were identified in the electronic search and 42 studies involving a total of 761 participants were included in the review (21 studies included for qualitative reporting and 21 studies in the meta-analysis). Most individual studies and the meta-analyses demonstrated no effect of ankle supports on ground reaction force or ankle inversion angle. However, there was high quality evidence that ankle taping decreased plantarflexion angle at initial contact during landing from a height (P = 0.0009, standerdised mean differences = 0.72, 95% confidence intervals = 1.15, 0.03, I 2 = 3%). The effect of ankle supports on transverse plane ankle biomechanics has not been adequately investigated. CONCLUSIONS: Ankle taping only decreased plantarflexion angle at initial contact during landing from a jump. Ankle supports did not affect inversion angle or forces in linear and multiplanar tasks. There was insufficient evidence on the effect of ankle supports on ankle transverse plane biomechanics.

Deprescribing paracetamol in pain conditions: A scoping review.

OBJECTIVE: To examine evidence on deprescribing paracetamol in pain conditions and inform future strategies for paracetamol deprescription. DESIGN: Scoping review. PARTICIPANTS: Adults with pain conditions, taking paracetamol. RESULTS: After two independent teams of reviewers screening for titles, abstracts, and then full texts, 16 original articles were included. Deprescribing strategies were grouped into 5 categories: (1) Pharmacological, (2) Psychological, (3) Physiological, (4) Policy, and (5) Combination. We found strategies were predominately consumer-focused, conducted in community settings and involved individuals experiencing musculoskeletal pain (such as low back pain and osteoarthritis). A total of twelve studies investigated interventions targeting dose reduction and four studies examined interventions focusing on discontinuation of paracetamol. The most common strategies used to deprescribe paracetamol in pain conditions were physiological strategies, followed by psychological strategies. All included studies demonstrated some level of effectiveness to deprescribe paracetamol in a pain conditions through dose reduction or discontinuation, although the effectiveness of deprescribing strategies were highly variable, ranging from the majority of participants discontinuing their paracetamol use, to less than 10% reducing their paracetamol use upon the latest follow-up. CONCLUSIONS: There are clear opportunities for prospective trials to be designed more purposely and primarily focused to influence reduction and cessation of paracetamol for specific pain conditions where deprescription is appropriate.

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.

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.
