Implementing good life with osteoArthritis from Denmark (GLA:D®) in Australian public hospitals. Part 2: Service providers' perceptions.

BACKGROUND: Previous literature has reported the successful implementation of the Good Life with osteoArthritis in Denmark (GLA:D®) program into predominantly private practice settings. There may be unique challenges present within the public hospital setting that influence GLA:D® implementation in public health. OBJECTIVE: Explore the attitudes and experiences of service providers directly involved in implementing GLA:D® in Australian public tertiary hospitals. DESIGN: Qualitative descriptive study design. METHOD: Service providers (n = 14) from three participating hospitals took part in semi-structured focus groups at the completion of the 6-month implementation period. Inductive thematic analysis was employed to identify primary domains across all facilities. RESULTS: Four broad domains were identified. Factors that influenced uptake included GLA:D® being a recognisable, evidence-based product requiring minimal development or adaptation. The fidelity of the GLA:D® Australia program was challenged by referral of patients with multiple/complex medical comorbidities, and patient preference to complete registry data via paper rather than online. Several operational considerations are required when delivering GLA:D® in a public hospital setting, including adequate numbers of GLA:D®-trained staff, additional screening requirements, obtaining appropriate clinical space, and persisting patient barriers to attending the service. GLA:D® provided benefits beyond improvement in pain and function, including social interactivity, high attendance and promotion of long-term self-management, while also maximising service efficiencies. CONCLUSIONS: Implementing GLA:D® in Australian public hospitals was supported by service providers. Specific operational and administrative factors, including staff training, patient complexity, and registry requirements should be considered when attempting to embed and sustain GLA:D® in large Australian public tertiary hospitals.

Concerns beyond ankle symptoms predominate healthcare professionals' views of patients with ankle osteoarthritis: A qualitative study.

OBJECTIVES: Explore healthcare professionals' perspectives on the main problems that their patients with ankle osteoarthritis experience and to propose health-related domains. METHODS: A qualitative study using semi-structured interviews was conducted with an international multidisciplinary group of healthcare professionals identified as ankle experts. Eligibility criteria were aged ≥18 years, and a certified healthcare professional with ≥ 5-year experience post-qualification in working with ankle osteoarthritis and/or chronic ankle pain. Interviews were recorded, transcribed verbatim and thematically analysed. RESULTS: Twenty-one healthcare professionals (20 males; mean (range) age 49 (34-72) years) from four professions (orthopaedic surgeons (n = 9), athletic trainers (n = 5), physiotherapists (n = 4) and podiatrists (n = 3)) were interviewed. Four main themes were identified: 1) people with ankle osteoarthritis have difficulty with weight-bearing activities; 2) symptoms of pain and stiffness predominate, alongside swelling, instability, weakness and poor balance; 3) chronic pain in ankle osteoarthritis has psychosocial consequences; and 4) the loss of activities of daily living and independence compromises quality of life. We proposed 15 health-related domains that emerge from the interview data. CONCLUSION: Healthcare professionals recognise that ankle osteoarthritis patients have difficulty in physical, sporting, and occupational weight-bearing activities, and they live with persistent ankle pain, stiffness and other symptoms that have physical and psychosocial consequences. The health-related domains derived from interviews with expert healthcare professionals will contribute to the development of a core domain set for ankle osteoarthritis.

An exploration of footwear preferences, attitudes and beliefs in people with knee osteoarthritis: A qualitative study.

BACKGROUND: Although footwear can improve pain and function in individuals with knee osteoarthritis (OA), perspectives about footwear in this population have not been explored. OBJECTIVES: This qualitative study explored preferences, attitudes and beliefs about footwear in adults with knee OA. METHODS: Twenty individuals with a clinical diagnosis of knee OA (aged 45-79 years, 65% women) participated in semi-structured interviews about factors which influence footwear selection, the effect of footwear on knee symptoms, and footwear modifications. Data were analysed thematically. RESULTS: Four themes, with sub-themes, were identified: i) there are specific footwear characteristics people look for, with comfort as their top priority; ii) shoe appearance is important; iii) footwear can aggravate or ease symptoms; and iv) people with knee OA find footwear in a variety of ways. Participants related built-in arch support, a cushioned insole and low/no heel, without addition of foot orthoses, to comfort, and were willing to pay more for comfort and quality. Appearance was also a consideration, and participants indicated they would tolerate short periods of symptom aggravation for aesthetic shoes. Participants felt that footwear choice affected their knee symptoms and risk of slipping/twisting. Participants reported that their footwear choices were determined through trial-and-error, and sometimes on advice from health professionals or shoe store salespersons. CONCLUSIONS: There are specific footwear features important to individuals with knee OA. Knowledge of these features can be used by health professionals to inform footwear discussions with knee OA patients and serve as considerations when developing footwear targeted for this population.

Work-related interventions are not commonly included in physiotherapy management of lower limb osteoarthritis: A cross-sectional survey of Australian Physiotherapists.

BACKGROUND: Lower limb osteoarthritis (OA) is a leading cause of disability and can affect an individual's ability to work. OBJECTIVES: To explore Australian physiotherapists' use of work-related interventions in managing patients with lower limb OA, and identify current management practices. METHODS: Physiotherapists with at least two years of experience treating patients with lower limb OA were invited to complete an online survey to understand how physiotherapists manage patients with lower limb OA, specifically regarding interventions related to work. RESULTS: A total of 132 physiotherapists completed the survey. In free text responses, only 1.5% and 2.3% of physiotherapists nominated work-related items in their key components of treatment or educational topics discussed with patients with lower limb OA, respectively. From a range of work-related activities presented, over half of physiotherapists indicated they regularly/always provided education about the benefits of remaining in work (63.5%) and advice on managing symptoms at work (57.4%). Less than 10% of physiotherapists regularly/always used a validated scale to identify barriers for work (9.6%), discussed absences from work (9.6%), conducted a workplace assessment (4.4%), and discussed submitting workers' compensation claims (2.6%). Exercise and patient education were the most frequently nominated physiotherapy treatments in free text (96.2% and 86.3%, respectively) and fixed response (99.2% and 93.9%, respectively) questions. CONCLUSION: Many physiotherapists do not address work-related activities in their management of patients with lower limb OA. In light of work-related challenges commonly experienced by individuals with lower limb OA, this is an important aspect of management of this condition.

Coach perspectives on factors that influence the implementation of injury prevention programs in community netball: A qualitative study.

OBJECTIVE: The Netball KNEE Program is an injury prevention program (IPP) developed by Netball Australia. It is promoted to coaches, but implementation is limited. This study explored community netball coaches' perspectives on factors that influence IPP implementation, and ideas on how it could be improved. METHODS: Twenty-four coaches from 16 netball clubs participated in semi-structured interviews that asked about their beliefs about injury prevention, use of and confidence in delivering IPP, barriers and facilitators to implementation, and suggestions to ease IPP implementation. Interviews were analysed using inductive thematic analysis. RESULTS: Two themes were identified - Factors that influence IPP implementation (4 sub-themes), and Suggestions to improve IPP implementation (2 sub-themes). Coaches thought early development of injury prevention habits was important. Life roles, coaching experience and engagement with development courses influenced IPP delivery. Coaches expressed concerns about Netball KNEE program length and complexity and lack of implementation support. They suggested the need for a short simple IPP and engagement with health/exercise professionals for implementation. CONCLUSIONS: This study engaged with stakeholders to identify barriers that need to be addressed to improve IPP implementation in netball. Coaches desired a short simple standardised IPP, and training from physiotherapists or exercise professionals on implementation.

Experiences of Working with Lower Limb Osteoarthritis: A Qualitative Study.

PURPOSE: Pain and disability associated with lower limb osteoarthritis (OA) may contribute to difficulties at work. This study aimed to understand the perspectives of workers with lower limb OA on difficulties, concerns, and coping strategies used at work. METHODS: Twenty-two individuals with lower limb OA who were working in paid employment participated in semi-structured interviews. Data were qualitatively analyzed using an inductive thematic approach. Codes were identified and refined through review of interview transcripts and discussion with the research team. RESULTS: Six themes were identified in relation to experiences working with lower limb OA. Themes were as follows: weight-bearing physical demands are challenging; lower limb OA can affect work performance; emotional consequences of pain; concerns about work in the future; positive experiences of supportive colleagues and managers; and minimal effects on sedentary work. Three themes were identified relating to strategies to manage at work: adjustments at work help manage pain and avoid exacerbations; regular strategies to manage pain; and healthcare professionals are consulted, but usually not specifically for work. CONCLUSIONS: Workers with lower limb OA experience physical and emotional difficulties at work that can impact work performance. Workers are concerned about longevity and job security and use a range of strategies to manage symptoms and remain at work. Employers, employees, and healthcare professionals may need to work together to create workplace accommodations to help workers with lower limb OA confidently remain in work.

Protocol for a randomised feasibility trial comparing a combined program of education and exercise versus general advice for ankle osteoarthritis.

BACKGROUND: Ankle osteoarthritis (OA) is a serious problem with high associated pain and disability. While education and exercise are recommended for the initial management of OA, this has not been investigated in ankle OA. The primary aim of this study is to establish the feasibility of running a full-scale randomised controlled trial (RCT) investigating a combined education and exercise program compared to a general advice program for people with ankle OA. The secondary aims are to collect preliminary data which will inform sample size calculations, and understand the perspectives of people with ankle OA on their participation in the trial. METHODS: Thirty individuals aged 35 years or older with symptomatic radiographic ankle OA will be recruited from the community and randomised to receive either a combined education and exercise program or a general advice program, both of which will be delivered by a physiotherapist in a group setting. Primary outcomes of feasibility include responses to study advertisements, number of eligible participants, recruitment rate, adherence with the intervention, fidelity of the intervention, adverse events, drop-out rate, and credibility and expectancy of the intervention. Secondary participant-reported outcomes will include global rating of change, patient acceptable symptom state, severity of ankle pain and stiffness, self-reported function, quality of life, satisfaction with treatment, and use of co-interventions. Follow up will be at 8 weeks and 3 months. Physical measures of 40 m walking speed, timed stairs descent, heel raise endurance and ankle dorsiflexion range of motion will be collected at baseline and 8 weeks. Primary feasibility outcomes will be reported descriptively, and estimates of the variability of secondary participant-reported and physical outcomes will be calculated. Semi-structured interviews will be conducted with participants to understand perspectives about the intervention and participation in the trial, with data analyzed thematically. DISCUSSION: Study findings will establish the feasibility of running a full-scale RCT to investigate a combined education and exercise program compared to a general advice program for people with ankle OA. This study is a necessary first step to advance the international research agenda of evaluating the efficacy of exercise in the management of ankle OA. TRIAL REGISTRATION: ACTRN12623000017628.

Work-related outcomes in individuals with and without lower limb osteoarthritis: an online survey.

OBJECTIVE: While osteoarthritis (OA) affects people who are still participating in the workforce, there is limited data about the impact of OA on work. The aim of this study was to compare work participation in individuals with and without lower limb OA. METHODS: This cross-sectional study included workers with (n = 124) and without (n = 106) lower limb OA. Work participation was assessed as work status (full/part time work), work ability (Work Ability Index (WAI)), absenteeism and presenteeism (World Health Organization's Health and Work Performance Questionnaire (WHO-HPQ)), and perceived difficulties meeting work demands (Work Role Functioning Questionnaire (WRFQ)). The data were analyzed using an analysis of covariance with age, body mass index and physical job demands included as covariates. RESULTS: Work ability was poorer (p < 0.001) and loss of work performance (p < 0.001) was higher among workers with OA than healthy controls. There was no statistical difference in absenteeism or overall ability to meet work demands between participants with and without lower limb OA. However, workers with lower limb OA had more difficulty with work scheduling demands (p = 0.05) and physical demands (p = 0.003) than healthy workers. CONCLUSION: Lower limb OA was associated with poorer work ability, loss of work performance and difficulty in meeting physical and work scheduling demands. Health professionals and employers should consider these challenges when managing individuals with lower limb OA and supporting them to remain in the workforce.

The effect of lower limb osteoarthritis on work-related outcomes: a systematic review and meta-analysis.

PURPOSE: Lower limb osteoarthritis (OA) is a prevalent condition that has a profound impact on an individual's life in several domains, including occupational activities. The objective of this study was to systematically describe and compare work-related outcomes (e.g., employment status, absenteeism, and productivity loss) in individuals with and without lower limb OA. MATERIALS AND METHODS: Five databases were searched until 17 June 2023. Studies were eligible for inclusion if they compared work-related outcomes between individuals with lower limb OA and healthy controls (e.g., people without OA or the general population). RESULTS: Seven studies met the inclusion criteria of which two were included in a meta-analysis. Meta-analysis revealed that individuals with OA were less frequently in paid employment than control individuals (odds ratio: 0.25; 95% confidence intervals: 0.12, 0.53). Evidence from single studies indicated greater absenteeism and presenteeism and poorer functional capacity in people with lower limb OA compared to controls. CONCLUSIONS: This systematic review suggests that individuals with lower limb OA have poorer work-related outcomes than those without OA. Low study numbers and lack of consistency in the way work outcomes are defined and measured make accurate quantification of the impact of OA on work challenging.Prospero: registration number: CRD42020178820.

Individuals with lower limb osteoarthritis (OA) are less frequently in paid employment and experience greater absenteeism and presenteeism and poorer functional capacity than people without OA.For holistic management of lower limb OA, healthcare providers should have conversations about any difficulties experienced at work and include outcome measures related to work.Clinicians should work with individuals with lower limb OA and employers to develop interventions to maximize work participation.

Falls and falls-related injuries in individuals with chronic ankle symptoms: a cross-sectional study.

BACKGROUND: Falls are a major public health concern globally. While falls are associated with osteoarthritis and persistent pain at the hip and knee, falls have not been investigated in people with chronic ankle symptoms. This study aimed to compare self-reported history of falls between adults with and without chronic ankle symptoms. Secondary aims were to compare concern about falling and balance confidence between groups, and to identify factors associated with falling. METHODS: A total of 226 participants (134 with chronic ankle pain and/or stiffness and 92 controls) participated in this cross-sectional case-control study. Participants completed an online questionnaire about falls in the past 12 months, injuries associated with falling, concern about falling, balance confidence, function, pain and multimorbidity. RESULTS: Eighty-six (64%) participants with chronic ankle symptoms and 24 (26%) controls reported at least one fall in the last 12 months (p < 0.001). Participants with chronic ankle symptoms reported more falls, more injurious falls, and more hospitalisations because of a fall than controls (p > 0.002). There was a small effect for lower balance confidence and higher concern about falling in symptomatic participants (standardised mean difference: 0.39-0.49; p > 0.017). Logistic regression analysis identified that falling was associated with the presence of ankle symptoms (3.08 (1.20, 7.92); p = 0.02) and concern about falling (odds ratio (95% confidence intervals): 1.13 (1.05, 1.23); p = 0.002). CONCLUSIONS: Falls and falls-related injuries are a problem in individuals with chronic ankle symptoms. The high falls occurrence and concern about falling in individuals with chronic ankle symptoms suggest the need for clinicians to assess these factors in this population.

"It's like a nail being driven in the ankle": A qualitative study of individuals' lived experiences to inform a core domain set for ankle osteoarthritis.

OBJECTIVES: Explore individuals' lived experience with ankle osteoarthritis and to identify health-related domains for ankle osteoarthritis based on the perspectives of people living with the condition, as an initial step to address the International Foot and Ankle Osteoarthritis Consortium's recommendation to develop a core domain set for ankle osteoarthritis. METHODS: A qualitative study using semi-structured interviews was conducted. Interviews were undertaken with individuals with symptomatic ankle osteoarthritis who were aged ≥35 years. Interviews were recorded, transcribed verbatim and thematically analysed. RESULTS: Twenty-three individuals (16 females; mean (range) age 62 (42-80) years) were interviewed. Five themes were identified: pain, often severe, is a central feature of living with ankle osteoarthritis; stiffness and swelling are key symptoms; ankle osteoarthritis induced mobility impairments compromise enjoyment in life; ankle osteoarthritis instability and balance impairments lead to concerns about falling; there are financial implications of living with ankle osteoarthritis. We propose 17 domains based on individuals' experiences. CONCLUSION: Study findings indicate that individuals with ankle osteoarthritis live with chronic ankle pain, stiffness and swelling which affect their ability to participate in physical, and social activities, maintain an active lifestyle, and work in physical occupations. From the data, we propose 17 domains that are important to people with ankle osteoarthritis. These domains require further evaluation to ascertain their inclusion in a core domain set for ankle osteoarthritis.

Characterising tibialis posterior tendinopathy using the International Classification of Functioning, Disability and Health: a cross sectional study.

BACKGROUND: Tibialis posterior tendinopathy (TPT) is characterised by pain around the medial foot/ankle and difficulties weightbearing. OBJECTIVE: Compare individuals who have TPT with asymptomatic controls across the International Classification of Functioning, Disability and Health (ICF) domains of body structure and function, activity, participation and personal factors. METHODS: Twenty-two individuals meeting the selection criteria for TPT (86% female, mean ± SD age:43 ± 13 years; body mass index [BMI]:28 ± 7 kg/m2) were compared to 27 controls (93% female, age:44 ± 16 years, BMI:23 ± 5 kg/m2). Standardised differences (and 95% confidence intervals [CIs]) between groups were estimated for outcomes under each ICF domain using Cliff's delta to allow for comparison of the magnitude of deficits across outcomes (>0.47 considered large). RESULTS: Impairments in body structure and function in individuals with TPT were accompanied by activity limitations including difficulties due to foot problems (-1.0 (-1.0, -1.0)) and with independent living (-0.8 (-1.0, -0.3)) and greater time to complete stair descent/ascent (-0.6 (-0.8, -0.3)). Considering participation, overall foot-related function (-1.0 (-1.0, -1.0)), ability to participate in activities (-0.7 (-0.08, -0.3)), social restrictions (-0.8 (-1.0, -0.4)) and quality of life (-0.7 (-0.9, -0.5)) were poorer in individuals with TPT. CONCLUSION: Individuals with TPT have large impairments in body structure and function, activity limitations and participation restrictions, particularly relating to independent living, mental health and pain. Personal factors appear to contribute to a lesser extent to the TPT presentation. Treatment plans should consider activity and participation limitations in addition to body structure and function.

Exploring women's experiences with persistent pain and pain management following breast cancer treatment: A qualitative study.

This qualitative study aimed to explore experiences of women with persistent pain following breast cancer treatment, including their perceptions about the cause of their pain, how they manage their pain and their interactions with healthcare providers related to their pain during and following breast cancer treatment. Fourteen women who experienced pain for more than 3 months following breast cancer treatment were recruited from the general breast cancer survivorship community. Focus groups and in-depth, semi-structured interviews were conducted by one interviewer, audio-recorded, and transcribed verbatim. Transcripts were coded and analysed using Framework Analysis. Three main descriptive themes emerged from the interview transcripts: (1) characteristics of pain, (2) interactions with healthcare providers and (3) pain management. Women had various types and degrees of persistent pain, all of which they believed were related to breast cancer treatment. Most felt like they were not given enough information pre- or post-treatment and believed their experience and ability to cope with pain would have been better if they were given accurate information and advice about (the possibility of) experiencing persistent pain. Pain management strategies ranged from trial and error approaches, to pharmacotherapy, and to 'just coping with the pain". These findings highlight the importance of the provision of empathetic supportive care before, during and after cancer treatment that can facilitate access to relevant information, multidisciplinary care teams (including allied health professionals) and consumer support.

Outcome measures in clinical studies of ankle osteoarthritis: a systematic review.

OBJECTIVE: To explore and describe the outcome measures reported in primary research of ankle osteoarthritis (OA) and to propose aligned health-related domains. METHODS: Six databases were searched, and studies were screened by two independent reviewers. Studies of participants with ankle OA who were> 18 years of age and reported outcome measure data were included. Non-English, animal, cadaveric, reviews, and studies with< 5 participants were excluded. Outcome measures were examined for content and mapped to health-related domains. RESULTS: 1386 studies were identified, of which 547 met selection criteria - reporting 250 outcome measures. Most commonly reported measures were the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (n = 257 studies), plain radiographs to measure ankle alignment (n = 211), numerical rating scale for pain severity (n = 177) and goniometry to measure ankle range of motion (n = 148). Outcome measures were organised into 19 domains. The most common domains were pain severity (315 (58%) studies), ankle alignment (254 (46%)), ankle motion (181 (33%)), disability (169 (31%)) and health-related quality of life (128 (23%)). These domains fell into the Outcome Measures in Rheumatology (OMERACT) core areas of life impact and pathophysiological manifestations. CONCLUSION: Many outcome measures are used in ankle OA research, most of which assess joint alignment, pain, and motion. Based on the outcome measures identified, we proposed 19 possible health-related domains, predominantly in the OMERACT core areas of life impact and pathophysiological manifestations of ankle OA. Clinicians and researchers can use this review in guiding selection of outcome measures.

Protocol for the development of a core domain set for individuals with ankle osteoarthritis.

BACKGROUND: Ankle osteoarthritis (OA) is a debilitating health condition that is increasing in prevalence. Currently, there are no evidence-based guidelines for managing ankle OA. One of the current challenges to establishing guidelines is the lack of a widely agreed-upon set of outcome measures that are consistently used in ankle OA research. Without a set of agreed-upon outcome measures, it is difficult to synthesise clinical trial outcomes through meta-analysis-an essential element of evidence-informed practice. In order to develop an appropriate set of outcome measures for ankle OA, it is important first to develop a core domain set. In this protocol, we describe the methodological approach that we will use to develop such a core domain set for ankle OA. METHODS: We established an international steering committee to guide the development of a core domain set for ankle OA. The core domain set development will follow a multi-staged approach consisting of three phases, involving participation by patients and clinicians/healthcare professionals. In phase 1, a list of candidate domains will be gleaned from (a) a scoping review of outcome measures used in ankle OA research, (b) qualitative interviews with individuals with ankle OA, and (c) qualitative interviews with healthcare professionals with expertise in ankle OA. In phase 2, the steering committee will review and generate a list of candidate domains from those gleaned in phase 1. In phase 3, this list of candidate domains will be considered in a Delphi process to reach a consensus on a core domain set. We anticipated this will involve 3 rounds of surveys. CONCLUSION: This protocol describes the methods that will be used to develop a core domain set of health-related aspects for ankle OA. Importantly, it will include both healthcare professional and patient involvement. This is a prerequisite step to developing a core outcome set for ankle OA that should be reported in all clinical trials for ankle OA. The findings will be widely disseminated across peer-refereed publication(s) and national and international conferences, as well as via relevant professional societies, patient support group organisations, and social media platforms. PROJECT REGISTRATION: This project is registered with the Core Outcome Measures in Effectiveness Trials (COMET) database on 17 March 2021. https://www.comet-initiative.org/Studies/Details/1837 .

Symptom characteristics in office workers using standing workstations: A cross-sectional study.

BACKGROUND: In some occupational groups, prolonged standing is associated with adverse symptoms. While the introduction of sit-stand workstations in office workers is increasingly common, the profile of symptom development is not known. OBJECTIVES: To identify and describe the location, intensity, quality, and timing of symptoms experienced by office workers while standing at a sit-stand workstation. METHODS: This cross-sectional observational study was performed in an university campus laboratory simulated as an office with a sit-stand workstation. Sixty-three office workers without low back pain or prior exposure to a sit-stand workstation participated. For primary outcome measures, participants recorded any symptoms of pain, stiffness, and/or fatigue on a body chart every 15 min during a 2-hour standing task. Participants rated symptom intensity on an 11-point numerical rating scale (NRS). RESULTS: Fifty-three participants (84%) experienced symptoms during the 2-hour standing task, with 30 participants (48%) reporting at least one symptom within 30 min of standing. A greater number of participants reported symptoms rated ≥2 on the NRS in the lumbar spine, lower extremity, and feet/ankle than the upper quadrant (odds ratios from 3.84 to 6.86). Mean maximal symptom intensity for the lumbar spine was greater than that for the upper quadrant and feet/ankles (incidence rate ratios: 1.46 to 1.79). CONCLUSION: Symptoms of pain, stiffness, and fatigue, especially those affecting the lumbar spine, lower extremity and feet/ankles are common in office workers who stand at a workstation. Study findings suggest that physical therapists should advise workers using sit-stand workstations to monitor symptoms and consider changing position within 30 min.

Thirty Minutes Identified as the Threshold for Development of Pain in Low Back and Feet Regions, and Predictors of Intensity of Pain during 1-h Laboratory-Based Standing in Office Workers.

This study with 40 office workers investigated (a) the effect of time spent standing on low- back and lower limb pain during a 1-h laboratory-based task; (b) the standing time after which a significant increase in pain is likely; and (c) the individual, physical and psychosocial factors that predict pain. The primary outcome was bodily location of pain and pain intensity on a 100-mm Visual Analogue Scale recorded at baseline and every 15 min. Physical measures included trunk and hip motor control and endurance. Self-report history of pain, physical activity, psychosocial job characteristics, pain catastrophizing and general health status were collected. Univariate analysis and regression models were included. The prevalence of low-back pain increased from 15% to 40% after 30 min while feet pain increased to 25% from 0 at baseline. The intensity of low-back and lower limb pain also increased over time. A thirty-minute interval was identified as the threshold for the development and increase in low-back and feet pain. Modifiable factors were associated with low-back pain intensity-lower hip abductor muscle endurance and poorer physical health, and with feet symptoms-greater body mass index and less core stability.

An Individualized Exercise Intervention for People with Multiple Myeloma-Study Protocol of a Randomized Waitlist-Controlled Trial.

People with multiple myeloma (MM) are second only to people with lung cancer for the poorest reported health-related quality of life (HRQoL) of all cancer types. Whether exercise can improve HRQoL in MM, where bone pain and lesions are common, requires investigation. This trial aims to evaluate the efficacy of an exercise intervention compared with control on HRQoL in people with MM. Following baseline testing, people with MM (n = 60) will be randomized to an exercise (EX) or waitlist control (WT) group. EX will complete 12-weeks of supervised (24 sessions) and unsupervised (12 sessions) individualized, modular multimodal exercise training. From weeks 12-52, EX continue unsupervised training thrice weekly, with one optional supervised group-based session weekly from weeks 12-24. The WT will be asked to maintain their current activity levels for the first 12-weeks, before completing the same protocol as EX for the following 52 weeks. Primary (patient-reported HRQoL) and secondary (bone health and pain, fatigue, cardiorespiratory fitness, muscle strength, body composition, disease response, and blood biomarkers) outcomes will be assessed at baseline, 12-, 24- and 52-weeks. Adverse events, attendance, and adherence will be recorded and cost-effectiveness analysis performed. The findings will inform whether exercise should be included as part of standard myeloma care to improve the health of this unique population.

Hip and knee muscle torque is not impaired in the first three months of a first-time lateral ankle sprain.

OBJECTIVES: The primary objective was to compare hip and knee isometric muscle strength between individuals with a first-time acute lateral ankle sprain and controls. A secondary objective was to investigate hip and knee isometric muscle strength three months post-injury. DESIGN: Cross-sectional and prospective follow-up components. SETTING: Laboratory environment. PARTICIPANTS: Forty-two participants (21 acute lateral ankle sprain and 21 controls) matched for age, sex, physical activity and leg dominance participated. MAIN OUTCOME MEASURES: Hip and knee isometric muscle torque was assessed using a rigidly fixated hand-held dynamometer. Testing in acute lateral ankle sprain participants was performed within four weeks of injury and three months post-injury. Controls were tested at one timepoint. RESULTS: There were no differences in hip or knee isometric muscle torque between acute lateral ankle sprain and control participants (mean differences <0.08). Hip and knee isometric muscle torque in acute ankle sprain participants did not differ between baseline and three months post-injury testing (mean difference <0.06). CONCLUSIONS: Proximal lower limb isometric strength is not impaired within the first three months of sustaining a first-time lateral ankle sprain injury. This implies that hip and knee isometric strength deficits in individuals with CAI may occur at some later stage.

Balance is impaired in symptomatic ankle osteoarthritis: A cross-sectional study.

BACKGROUND: Ankle osteoarthritis (OA) is associated with several physical impairments but investigations into balance impairments in this population are limited. Understanding balance impairments in ankle OA may help inform the management of this condition. RESEARCH QUESTION: Does balance overall performance differ between individuals with symptomatic radiographic ankle OA, asymptomatic radiographic ankle OA and healthy controls? Are there any differences in mediolateral or anteroposterior balance, or confidence to perform balance tasks between these groups? METHODS: Ninety-six volunteers (31 symptomatic radiographic ankle OA, 41 asymptomatic radiographic ankle OA and 24 healthy controls) completed six static balance tasks: bilateral stance on a firm surface, bilateral stance on foam, and tandem stance, all performed with eyes open and closed. Centre of pressure (COP) data were collected using force plates. Confidence to perform each balance task was collected using an 11-point numerical rating scale. RESULTS: Compared to controls, participants with symptomatic radiographic ankle OA had greater COP area when standing on a firm surface, foam and in tandem with eyes closed (all p < 0.05) and greater total COP sway in both firm surface and tandem stance conditions (p < 0.04). Participants with symptomatic ankle OA had greater COP area (p < 0.04) and total COP sway (p = 0.01) than those with asymptomatic ankle OA during tandem stance. Total COP sway and area were similar between asymptomatic ankle OA and control participants. Some differences in mediolateral and anteroposterior balance were identified between groups. Individuals with symptomatic ankle OA had lower confidence to perform the tandem stance eyes closed task compared to controls. SIGNIFICANCE: Balance impairments and decreased balance confidence were identified in those with symptomatic radiographic ankle OA compared to asymptomatic individuals with and without radiographic ankle OA. This suggests that balance deficits in ankle OA may be related to symptoms, rather than radiographic evidence of disease.
