Effects of an online program including mindfulness, exercise therapy and patient education compared to online exercise therapy and patient education for people with Patellofemoral Pain: protocol for a randomized clinical trial.

BACKGROUND: Patellofemoral pain (PFP) is a common knee disorder that causes persistent pain, lower self-reported function and quality of life. People with PFP also present with altered psychological factors, which are associated with higher levels of pain and dysfunction. Mindfulness-based interventions (MBI) generally consist of meditative practices developed to provide a holistic approach to chronic conditions. However, the effects of MBI on clinical and psychological outcomes for people with PFP remains understudied. METHODS: This assessor-blinded, parallel, two-arm randomized clinical trial aims to investigate the effects of adding an 8-week online MBI program to exercise therapy and patient education on clinical and psychological factors for people with PFP. We also aim to investigate whether psychological factors mediate changes in pain and function. Sixty-two participants with PFP will be recruited and randomized into one of two treatment groups (Mindfulness or Control group). Both groups will receive an 8-week intervention involving exercise therapy and education delivered through an online platform. The Mindfulness group will additionally receive a MBI component including formal and informal practices. Outcomes will be assessed online at baseline, intervention endpoint (follow-up 1) and 12 months after intervention completion (follow-up 2). Comparisons between groups will be performed at all time points with linear mixed models. A mediation analysis will be performed using a 3-variable framework. DISCUSSION: Exercise therapy and patient education are considered the "best management" options for PFP. However, unsatisfactory long-term prognosis remains an issue. It is known that people with PFP present with altered psychological factors, which should be considered during the evaluation and treatment of people with PFP. Adding a MBI to the current best treatment for PFP may improve short and long-term effects by addressing the underlying psychological factors.

The effectiveness of biofeedback for improving pain, disability and work ability in adults with neck pain: A systematic review and meta-analysis.

BACKGROUND: Biofeedback is used to optimise muscle activation patterns in people with neck pain. OBJECTIVES: To evaluate the safety and efficacy of electromyographic and pressure biofeedback on pain, disability and work ability in adults with neck pain. DESIGN: Systematic review and meta-analysis. METHODS: We searched key databases and trial registries to September 2020, using terms synonymous with 'neck pain' and 'biofeedback'. We included randomised controlled trials (RCTs) evaluating biofeedback (against any comparison) for adults with neck pain. Outcomes included pain, disability, work ability and adverse events. Two authors independently selected the studies, extracted data, and evaluated risk of bias. GRADE was applied to each meta-analysis. Data were pooled using random-effects models to determine the standardised mean change (SMC). RESULTS: We included 15 RCTs (n = 990). Moderate-quality evidence suggests biofeedback has a moderate effect on reducing short-term disability (SMC = -0.42, 95%CI: 0.59 to -0.26, nine trials, n = 627), and a small effect on reducing intermediate-term disability (SMC = -0.30, 95%CI: 0.53 to -0.06, five trials, n = 458). Biofeedback had no effect on pain or work ability in the short- and intermediate-term (low-to moderate-quality evidence). One study reported headaches in 6.7% of participants, but headache frequency was not reported by group. LIMITATIONS: There were a variety of control interventions across studies. Few studies compared biofeedback with no treatment or placebo. CONCLUSION: Biofeedback appears to have a small-to-moderate effect on reducing neck pain disability in the short- and intermediate-term, but no effect on pain or work ability. More trials reporting adverse events and comparing biofeedback to placebo are needed.

Wrist and hand pain in orthopaedic physical therapists: A mixed-methods study.

BACKGROUND: Orthopaedic physical therapists (PTs) who perform manual therapy are at high risk for wrist and hand pain. Studies that examine the magnitude, scope and causes of wrist and hand pain are needed so that prevention programs can be developed. OBJECTIVES: The objective of this study was to determine the magnitude, scope, and impact of wrist and hand pain in orthopaedic PTs and to identify potential strategies for prevention. DESIGN: This was a sequential, mixed methods study including quantitative and qualitative components. METHODS: The quantitative phase consisted of an online survey sent to members of the Academy of Orthopaedic Physical Therapy. The qualitative phase consisted of focus groups with Orthopaedic PTs who had wrist and hand pain. RESULTS: The survey included 962 PTs and the focus groups included 10 PTs. The one-year prevalence of wrist and hand pain was 75%. Increasing age, decreasing experience, female gender, performing more manual therapy and working more than 40 h per week were associated with an increased risk of moderate to severe wrist and hand pain. Soft-tissue mobilization was the most frequently cited causative factor. The most commonly mentioned strategy for prevention was altering body mechanics and technique. Focus group participants highlighted the importance of managing expectations for manual therapy by patients. CONCLUSIONS: Formal injury prevention programs for PT students and PTs are urgently needed. These programs should focus on improving body mechanics and technique, attention to workload, careful selection of manual techniques, and managing expectations for manual therapy.

Musculoskeletal pain associated with recreational yoga participation: A prospective cohort study with 1-year follow-up.

BACKGROUND: Yoga is a popular complementary therapy for musculoskeletal pain. There are few studies however, that have examined the risks of recreational participation for causing musculoskeletal pain. OBJECTIVES: To examine the relationship between musculoskeletal pain and recreational yoga participation. METHODS: This was a prospective cohort study with one-year follow-up. Data were collected via electronic questionnaires, one year apart. Outcomes included incidence and impact of pain caused by yoga and prevalence of pain caused, exacerbated, unaffected, and improved by yoga. Predictors included age, experience, hours of participation, and intensity of participation. RESULTS: The final sample included 354 participants from two suburban yoga studios. The incidence rate of pain caused by yoga was 10.7%. More than one-third of incident cases resulted in lost yoga participation time and/or symptoms lasting more than 3 months. None of the risk factors at baseline increased the risk for subsequent incident cases of pain caused by yoga. CONCLUSIONS: Yoga can cause musculoskeletal pain. Participants may benefit from disclosure of practice to their healthcare professionals and by informing teachers of injuries they may have prior to participation. Yoga teachers should also discuss the risks for injury with their students.

What interventions can improve quality of life or psychosocial factors of individuals with knee osteoarthritis? A systematic review with meta-analysis of primary outcomes from randomised controlled trials.

OBJECTIVE: To systematically review evidence of primary outcomes from randomised controlled trials (RCTs) examining the effect of treatment strategies on quality of life (QoL) or psychosocial factors in individuals with knee osteoarthritis (OA). DESIGN: Systematic review with meta-analysis. DATA SOURCES: Medline, Embase, SPORTDiscus, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Web of Science were searched from inception to November 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included RCTs investigating the effect of conservative interventions on QoL or psychosocial factors in individuals with knee OA. Only RCTs considering these outcomes as primary were included. RESULTS: Pooled data supported the use of exercise therapy compared with controls for improving health-related and knee-related QoL. There was limited evidence that a combined treatment of yoga, transcutaneous electrical stimulation and ultrasound may be effective in improving QoL. Limited evidence supported the use of cognitive behavioural therapies (with or without being combined with exercise therapy) for improving psychosocial factors such as self-efficacy, depression and psychological distress. SUMMARY/CONCLUSION: Exercise therapy (with or without being combined with other interventions) seems to be effective in improving health-related and knee-related QoL or psychosocial factors of individuals with knee OA. In addition, evidence supports the use of cognitive behavioural therapies (with or without exercise therapy) for improving psychosocial factors such as self-efficacy, depression and psychological distress in individuals with knee OA.

Can we have an overall osteoarthritis severity score for the patellofemoral joint using magnetic resonance imaging? Reliability and validity.

This work aimed to assess inter-rater reliability and agreement of a magnetic resonance imaging (MRI)-based Kellgren and Lawrence (K&L) grading for patellofemoral joint osteoarthritis (OA) and to validate it against the MRI Osteoarthritis Knee Score (MOAKS). MRI scans from people aged 45 to 75 years with chronic knee pain participating in a randomised clinical trial evaluating dietary supplements were utilised. Fifty participants were randomly selected and scored using the MRI-based K&L grading using axial and sagittal MRI scans. Raters conducted inter-rater reliability, blinded to clinical information, radiology reports and other rater results. Intra- and inter-rater reliability and agreement were evaluated using the intra-class correlation coefficient (ICC) and Cohen's weighted kappa. There was a 2-week interval between the first and second readings for intra-rater reliability. Validity was assessed using the MOAKS and evaluated using Spearman's correlation coefficient. Intra-rater reliability of the K&L system was excellent: ICC 0.91 (95% CI 0.82-0.95); weighted kappa (ĸ = 0.69). Inter-rater reliability was high (ICC 0.88; 95% CI 0.79-0.93), while agreement between raters was moderate (ĸ = 0.49-0.57). Validity analysis demonstrated a strong correlation between the total MOAKS features score and the K&L grading system (ρ = 0.62-0.67) but weak correlations when compared with individual MOAKS features (ρ = 0.19-0.61). The high reliability and good agreement show consistency in grading the severity of patellofemoral OA with the MRI-based K&L score. Our validity results suggest that the scale may be useful, particularly in the clinical environment. Future research should validate this method against clinical findings.

Effect of Injury Prevention Programs that Include the Nordic Hamstring Exercise on Hamstring Injury Rates in Soccer Players: A Systematic Review and Meta-Analysis.

BACKGROUND: Hamstring injuries are among the most common non-contact injuries in sports. The Nordic hamstring (NH) exercise has been shown to decrease risk by increasing eccentric hamstring strength. OBJECTIVE: The purpose of this systematic review and meta-analysis was to investigate the effectiveness of the injury prevention programs that included the NH exercise on reducing hamstring injury rates while factoring in athlete workload. METHODS: Two researchers independently searched for eligible studies using the following databases: the Cochrane Central Register of Controlled Trials via OvidSP, AMED (Allied and Complementary Medicine) via OvidSP, EMBASE, PubMed, MEDLINE, SPORTDiscus, Web of Science, CINAHL and AusSportMed, from inception to December 2015. The keyword domains used during the search were Nordic, hamstring, injury prevention programs, sports and variations of these keywords. The initial search resulted in 3242 articles which were filtered to five articles that met the inclusion criteria. The main inclusion criteria were randomized controlled trials or interventional studies on use of an injury prevention program that included the NH exercise while the primary outcome was hamstring injury rate. Extracted data were subjected to meta-analysis using a random effects model. RESULTS: The pooled results based on total injuries per 1000 h of exposure showed that programs that included the NH exercise had a statistically significant reduction in hamstring injury risk ratio [IRR] of 0.490 (95 % confidence interval [CI] 0.291-0.827, p = 0.008). Teams using injury prevention programs that included the NH exercise reduced hamstring injury rates up to 51 % in the long term compared with the teams that did not use any injury prevention measures. CONCLUSIONS: This systematic review and meta-analysis demonstrates that injury prevention programs that include NH exercises decrease the risk of hamstring injuries among soccer players. A protocol was registered in the International Prospective Register of Systematic Reviews, PROSPERO (CRD42015019912).
