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.

EXACT: EXercise or Advice after ankle fraCTure. Design of a randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods/Design</p> <p>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 <it>Advice </it>or <it>Rehabilitation </it>group. Participants in the <it>Advice </it>group will receive verbal and written advice about exercise at the time of removal of immobilisation. Participants in the <it>Rehabilitation </it>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.</p> <p>Discussion</p> <p>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.</p

The effects of warm-up on physical performance are not clear

Background: Warm-up is commonly used as part of an exercise programme. Previous reviews have cast doubts on the beneficial effects long thought to be associated with warm-up.1 2 However, recent evidence indicates that warm-up prevents sports-related injuries.3,–,5 Warm-up in the form of stretching has a small effect in reducing muscle soreness following exercise3 and leads to an increase in joint range of motion, but magnitude of the increase is small. Thus, it has an uncertain clinical importance.6 7 In addition to preventing muscle soreness and injury, another possible benefit of warm-up is enhanced physical performance. Only one previous review has examined the effects of warm-up on performance,2 but found limited evidence. Hence, the effects of warm-up on performance during sport or physical activity are not clear. Aim: The aim of the systematic review was to investigate the effects of warm-up on performance of physical activity

Usage evaluation of a resource to support evidence-based physiotherapy : the Physiotherapy Evidence Database (PEDro)

Objectives: The Physiotherapy Evidence Database (PEDro) is a free, web-based database of reports of randomised controlled trials, systematic reviews and evidence-based clinical practice guidelines in physiotherapy. The objective of this study was to describe the usage of PEDro over a 2-year period, including the number of visits and searches performed, the number of countries and territories from which users accessed PEDro, and amount of usage from each country. Design: Survey of web-site and database log files. Main outcome measures: Usage of the PEDro home-page (www.pedro.org.au) and the search function were logged for a 2-year period. Visit and search data were used to calculate the number of visits and searches each month. Domain data were used to calculate the total number of countries accessing PEDro and the amount of usage from each country and territory. Results: The PEDro home-page received 921,181 visits from 205 countries and territories in 2010 and 2011, with 3,350,740 new searches performed. On average, a new search was initiated every 19 seconds. The highest usage was from the United States of America (15%), Australia (13%) and Brasil (8%). Highest normalised usage was from Peru (255 searches/physiotherapist), Chile (154) and Columbia (90), and from Australia (19,883 searches/million-population), New Zealand (13,267) and Switzerland (11,361). Conclusions: There was substantial use of the PEDro resource by the global physiotherapy community during 2010 and 2011. The provision of the PEDro search function in languages other than English may enhance accessibility

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

Abstract 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.

What are the clinical recommendations for the use of ankle braces? A scoping review

Background: Ankle braces can be used in the treatment and prevention of lateral ankle sprains. However, there is a limited understanding and consensus about which type of brace should be used, for how long, and when to stop using ankle braces. Objective: To review the clinical recommendations made in guidelines or position statements for the use of ankle braces. Design: Scoping review. Methods: Ten electronic databases and Google were searched. Guidelines and/or position statements about treatment and/or prevention of lateral ankle sprains or chronic ankle instability were included if derived from a peer-reviewed source or from an official national or international professional group, society or association, and made recommendations on the use ankle braces. Recommendations for brace use and cessation were extracted, collated, reviewed, and presented in tabular format. Results: Eleven guidelines and two position statements were included. All recommended ankle braces for the treatment of grade I and II ankle sprains and prevention of recurring sprains. Inconsistencies were present for; grade III sprains, the classification and definitions for brace types, the level of restriction ankle braces provide, how long ankle braces should be worn, and indicators for cessation of use. Conclusion: Ankle braces are recommended for prevention of recurring sprains and the treatment of grade I and II sprains. Further information is needed on the duration or indicators for cessation of ankle brace use. A standardised classification and definitions used for the type of brace, and the level of restriction ankle braces provide is also warranted

Reduced physical activity in people following ankle fractures: a longitudinal study

Study Design Longitudinal observational cohort. Background The impact of ankle fracture on physical activity and sitting time and the course of recovery of physical activity are unclear. Objectives To assess the course of recovery of physical activity after ankle fracture and the extent to which this population may be less physically active and more sedentary than the general population. Methods A cohort of individuals with ankle fracture was derived from a randomized trial and assessed with the International Physical Activity Questionnaire-Short Form (IPAQ-SF) at immobilization removal and 1, 3, and 6 months later. Total metabolic equivalent (MET) minutes per week were calculated to evaluate the course of recovery of physical activity. Sitting time (minutes per day) and the percentage of those who met the World Health Organization physical activity guidelines were calculated. Normative data were derived from a population-based cohort study that assessed physical activity using the IPAQ-SF. Results In people with ankle fracture (n = 214), physical activity increased in the first month (from a median of 99 at immobilization removal to 979 MET min/wk) and leveled off by 6 months (1386 MET min/wk). Only 22% of the ankle fracture cohort met World Health Organization guidelines at immobilization removal, compared to 80% of the cohort from the general population (P\u3c.001). This difference diminished over time. Sitting time in the ankle fracture cohort was higher than population norms at all time points (P\u3c.001). Conclusion People with ankle fracture are less physically active and more sedentary than the general population. Strategies to increase physical activity must be considered

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
