Physical Therapist-Delivered Pain Coping Skills Training and Exercise for Knee Osteoarthritis: Randomized Controlled Trial

Physical activity, sedentary behaviour and well-being: experiences of people with knee and hip osteoarthritis

Living with knee and hip osteoarthritis (OA) means living with pain and difficulty in movement. Given the beneficial effects of physical activity (PA) and reduction of sedentary behaviour (SB), these behaviours need to be understood in the context of individuals' daily lives and sense of well-being. Twelve individuals (age: 43-79 years; 67% female) with knee and/or hip OA purposively selected (e.g., age, OA duration, OA severity) participated in semi-structured interviews. Data was analysed using inductive thematic analysis. PA and SB were narrated as multifaceted experiences with two overarching themes, PA negotiations (valuing mobility, the burden of osteoarthritis, keep going, the feel-good factor), SB negotiations (the joy of sitting, a lot is too bad, the osteoarthritis confines), and two overlapping themes (the life context, finding a balance). Physical and psychological aspects of PA and SB experiences were interwoven. Participants valued mobility and were proactively trying to preserve it by keeping active. A constant negotiation among the OA burden, the need to enjoy life and life circumstances was underlying PA behaviour. Prescription and encouragement of a physically active lifestyle in this population should be linked to mobility-related personal values and sense of well-being, while addressing concerns around OA-safety and normalizing PA trade-offs.

Cost-Effectiveness of Treatments for Musculoskeletal Conditions Offered by Physiotherapists: A Systematic Review of Trial-Based Evaluations

BACKGROUND

Musculoskeletal conditions are a leading contributor to disability worldwide. The treatment of these conditions accounts for 7% of health care costs in Germany and is often provided by physiotherapists. Yet, an overview of the cost-effectiveness of treatments for musculoskeletal conditions offered by physiotherapists is missing. This review aims to provide an overview of full economic evaluations of interventions for musculoskeletal conditions offered by physiotherapists.

METHODS

We systematically searched for publications in Medline, EconLit, and NHS-EED. Title and abstracts, followed by full texts were screened independently by two authors. We included trial-based full economic evaluations of physiotherapeutic interventions for patients with musculoskeletal conditions and allowed any control group. We extracted participants' information, the setting, the intervention, and details on the economic analyses. We evaluated the quality of the included articles with the Consensus on Health Economic Criteria checklist.

RESULTS

We identified 5141 eligible publications and included 83 articles. The articles were based on 78 clinical trials. They addressed conditions of the spine (n = 39), the upper limb (n = 8), the lower limb (n = 30), and some other conditions (n = 6). The most investigated conditions were low back pain (n = 25) and knee and hip osteoarthritis (n = 16). The articles involved 69 comparisons between physiotherapeutic interventions (in which we defined primary interventions) and 81 comparisons in which only one intervention was offered by a physiotherapist. Physiotherapeutic interventions compared to those provided by other health professionals were cheaper and more effective in 43% (18/42) of the comparisons. Ten percent (4/42) of the interventions were dominated. The overall quality of the articles was high. However, the description of delivered interventions varied widely and often lacked details. This limited fair treatment comparisons.

CONCLUSIONS

High-quality evidence was found for physiotherapeutic interventions to be cost-effective, but the result depends on the patient group, intervention, and control arm. Treatments of knee and back conditions were primarily investigated, highlighting a need for physiotherapeutic cost-effectiveness analyses of less often investigated joints and conditions. The documentation of provided interventions needs improvement to enable clinicians and stakeholders to fairly compare interventions and ultimately adopt cost-effective treatments.

Cognitive behavioral therapy achieves better benefits in relieving postoperative pain and improving joint function: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Cognitive behavioral therapy (CBT) is a structured, short-term psychotherapy approach that may have positive effects in terms of relieving postoperative pain. The main objective of this study was to determine the effect of CBT on pain and joint function in patients after total joint arthroplasty.

METHODS

We searched 3 electronic databases including randomized controlled studies (RCTs) using CBT as an intervention. The main results of this study were to determine pain intensity by NRS, VAS, WOMAC pain Scale, PCS, and joint function by HHS, OKS, EQ-5D, ROM. Data extraction and quality assessment of included RCTs were independently performed by the authors and date analysis was performed by RevMan V.5.4.

RESULTS

Among the 605 studies, 9 RCTS were included in this systematic review and meta-analysis. The study showed that the difference between CBT and usual care groups in PCS (≤3months), NRS, VAS (≤3months) were statistically significant (P < 0.05); the difference between CBT and usual care groups in PCS (≥12months), WOMAC Pain Scale, and VAS (≥12months) were not statistically significant (P > 0.05), indicating that CBT can improve pain in patients after arthroplasty in the early term. In addition, the difference between CBT and usual care groups in OKS (≤3months), HSS, ROM (≤3months), EQ-5D (≤3months) were not statistically significant (P > 0.05); the difference between CBT and usual care groups in EQ-5D (≥12months) were statistically significant (P < 0.05), indicating that the quality of life in patients after total joint arthroplasty were improved with the extension of follow-up time.

CONCLUSIONS

This study shows that CBT can relieve pain in patients with total joint arthroplasty in the early postoperative period and improve quality of life to some extent over time.

Neurophysiological pain education for patients with symptomatic knee osteoarthritis: A systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of neurophysiological pain education in patients with symptomatic knee osteoarthritis considering pain-related variables.

METHODS

A systematic review and meta-analysis was carried out according to the PRISMA guidelines. A search was conducted in PubMed, PEDro Database, Cochrane Library, Scopus, and Web of Science. Only randomized controlled trials enrolling patients ≥ 18 years of age with symptomatic knee osteoarthritis were included. The Downs and Black quality assessment tool was used to assess the quality of the articles, and the risk of bias was evaluated with the Cochrane Risk of Bias Assessment Tool.

RESULTS

A total of 7 studies were included in the study. Most of the studies were rated as "fair" on the Downs and Black quality assessment tool, and in the category of "some concerns" according to the Cochrane Risk of Bias Assessment Tool. Neurophysiological pain education was conducted alone or combined with exercise, joint mobilizations, or self-management programs. The number of sessions ranged from 1 to 10. The meta-analysis results showed significant differences in favor of the intervention group in pain (MD = -0.49; 95% CI = -0.66; -0.32; p < 0.001) and catastrophization (MD = -1.81; 95% CI = -3.31, -0.3; p = 0.02).

CONCLUSION, PRACTICE IMPLICATIONS

Neurophysiological pain education interventions in isolation or combined with exercise, joint mobilizations, or self-management programs have proven to significantly improve pain and catastrophization in patients with symptomatic knee osteoarthritis. These findings could provide clinicians with more information regarding the management of patients with symptomatic knee osteoarthritis.

If You Build It, Will They Come? Patient and Provider Use of a Novel Hybrid Telehealth Care Pathway for Low Back Pain

OBJECTIVE

The purpose of this study was to describe the referrals and use of a hybrid care model for low back pain that includes on-site care by physical therapists, physical activity training, and psychologically informed practice (PiP) delivered by telehealth in the Improving Veteran Access to Integrated Management of Low Back Pain (AIM-Back) trial.

METHODS

Data were collected from November 2020 through February 2023 from 5 Veteran Health Administration clinics participating in AIM-Back, a multisite, cluster-randomized embedded pragmatic trial. The authors extracted data from the Veteran Health Administration Corporate Data Warehouse to describe referral and enrollment metrics, telehealth use (eg, distribution of physical activity and PiP calls), and treatments used by physical therapists and telehealth providers.

RESULTS

Seven hundred one veterans were referred to the AIM-Back trial with 422 enrolling in the program (consult-to-enrollment rate = 60.2%). After travel restrictions were lifted, site visits resulted in a significant increase in referrals and a number of new referring providers. At initial evaluation by on-site physical therapists, 92.2% of veterans received pain modulation (eg, transcutaneous electrical nerve stimulation, manual therapy). Over 81% of enrollees completed at least 1 telehealth physical activity call, with a mean of 2.8 (SD = 2.0) calls out of 6. Of the 167 veterans who screened as medium to high risk of persistent disability, 74.9% completed at least 1 PiP call, with a mean of 2.5 (SD = 2.0) calls out of 6. Of those who completed at least 1 PiP call (n = 125), 100% received communication strategies, 97.6% received pain coping skills training, 89.6% received activity-based treatments, and 99.2% received education in a home program.

CONCLUSION

In implementing a hybrid care pathway for low back pain, the authors observed consistency in the delivery of core components (ie, pain modulation, use of physical activity training, and risk stratification to PiP), notable variability in telehealth calls, high use of PiP components, and increased referrals with tailored provider engagement.

IMPACT

These findings describe variability occurring within a hybrid care pathway and can inform future implementation efforts.

From sceptic to believer: Acceptability of cognitive muscular therapyTM , a new intervention for knee osteoarthritis

BACKGROUND

Cognitive Muscular TherapyTM (CMT) is an integrated behavioural intervention developed for knee osteoarthritis. CMT teaches patients to reconceptualise the condition, integrates muscle biofeedback and aims to reduce muscle overactivity, both in response to pain and during daily activities. This nested qualitative study explored patient and physiotherapist perspectives and experiences of CMT.

METHODS

Five physiotherapists were trained to follow a well-defined protocol and then delivered CMT to at least two patients with knee osteoarthritis. Each patient received seven individual clinical sessions and was provided with access to online learning materials incorporating animated videos. Semi-structured interviews took place after delivery/completion of the intervention and data were analysed at the patient and physiotherapist level.

RESULTS

Five physiotherapists and five patients were interviewed. All described a process of changing beliefs throughout their engagement with CMT. A framework with three phases was developed to organise the data according to how osteoarthritis was conceptualised and how this changed throughout their interactions with CMT. Firstly, was an identification of pain beliefs to be challenged and recognition of how current beliefs can misalign with daily experiences. Secondly was a process of challenging and changing beliefs, validated through new experiences. Finally, there was an embedding of changed beliefs into self-management to continue with activities.

CONCLUSION

This study identified a range of psychological changes which occur during exposure to CMT. These changes enabled patients to reconceptualise their condition, develop a new understanding of their body, understand psychological processes, and make sense of their knee pain.

Adapting a Clinical Practice Guideline for Management of Patients with Knee and Hip Osteoarthritis by Hong Kong Physiotherapists

Knee and hip osteoarthritis are common disabling conditions globally. Although numerous international clinical practice guidelines exist to guide physiotherapy management, not all recommendations issued from these guidelines can be translated to other contexts without considering the cultural acceptability and clinical implementability of targeted countries. Because the ADAPTE framework provides a robust methodology to adapt guidelines to the local context, this study used its methodology to adapt high-quality guideline recommendations to promote optimal physiotherapy care for knee and hip osteoarthritis in Hong Kong. The ADAPTE framework was used and modified to complete the adaptation process. International clinical practice guidelines were identified from eight guideline clearinghouses and six electronic databases. Two independent reviewers critically appraised the eligible guidelines using the AGREE II tool. We extracted and tabulated recommendations from high-quality guidelines. A voting-based consensus among interdisciplinary experts was conducted to decide on suitable recommendations for the Hong Kong context and whether there was a need to modify them. Pertinent recommendations were then translated into the traditional Chinese language. Our team members suggested modifying four tools and adding one to explore the patient's feedback on the recommendations, to the ADAPTE framework. The adaptation was performed on three high-quality guidelines. We adapted 28 and 20 recommendations for treating knee and hip osteoarthritis, respectively. We recommend a multimodal treatment for managing knee and hip osteoarthritis. Land- and aquatic-based exercises, patient education, and self-management were strongly recommended for patients with knee osteoarthritis. Land- and aquatic-based exercises were strongly recommended for patients with hip osteoarthritis. This is the first adaptation study in Hong Kong. It provides guidance to local physiotherapists on managing patients with knee and hip osteoarthritis. Future studies should test the effectiveness of implementing this adapted guideline to improve local physiotherapy care in Hong Kong.

The addition of structured lifestyle modifications to a traditional exercise program for the management of patients with knee osteoarthritis: A systematic review and meta-analysis of randomised trials

BACKGROUND

Guidelines recommend exercise for the management of knee osteoarthritis (OA), however, recently it has been suggested that including additional lifestyle modifications with a traditional exercise program may elicit greater benefits than exercise alone.

OBJECTIVES

To investigate the influence of the addition of lifestyle modifications to a traditional exercise program, with respect to functional outcomes and quality of life among individuals with knee OA.

DESIGN

Systematic review and meta-analysis.

METHODS

Four databases were searched to identify randomised controlled trials comparing an exercise program, which included the addition of lifestyle modifications, to an exercise program alone in individuals with knee OA. Methodological quality of included studies was assessed via the PEDro scale. Results synthesis through meta-analysis using a random effects model was conducted to determine the pooled effect on eligible outcomes and a GRADE approach was utilised to rate the certainty of evidence.

RESULTS

Meta-analysis of seven studies showed the inclusion of lifestyle modifications to an exercise program can further decrease pain intensity (SMD -0.68 [95% CI -1.26 to -0.10]), improve joint stiffness (MD -0.69 [95% CI -1.21, -0.17]) and increase physical function (MD -1.26 s ([95% CI -1.34, -1.17]) at six-months. Individual results showed improvements in quality of life with the addition of lifestyle modifications, however, this was not demonstrated through meta-analysis.

CONCLUSION

This systematic review supports the inclusion of additional lifestyle modifications to a traditional exercise program, for pain intensity, joint stiffness and physical function for individuals with knee OA.

Fundamentals of osteoarthritis. Rehabilitation: Exercise, diet, biomechanics, and physical therapist-delivered interventions

Insights related to the pathogenesis of osteoarthritis (OA) have informed rehabilitative treatments that aim to mitigate the influence of several known impairments and risk factors for OA, with the goal to improve pain, function, and quality of life. The purpose of this invited narrative review is to provide fundamental knowledge to non-specialists about exercise and education, diet, biomechanical interventions, and other physical therapist-delivered treatments. In addition to summarizing the rationale for common rehabilitative therapies, we provide a synthesis of current core recommendations. Robust evidence based on randomized clinical trials supports exercise with education and diet as core treatments for OA. Structured, supervised exercise therapy is advised. The mode of exercise may vary but should be individualized. The dose should be based on an initial assessment, the desired physiological changes, and progressed when appropriate. Diet combined with exercise is strongly recommended and studies demonstrate a dose-response relationship between the magnitude of weight loss and symptom improvement. Recent evidence suggests the use of technology to remotely deliver exercise, diet and education interventions is cost-effective. Although several studies support the mechanisms for biomechanical interventions (e.g., bracing, shoe inserts) and physical therapist-delivered (passive) treatments (e.g., manual therapy, electrotherapeutic modalities) fewer rigorous randomized trials support their clinical use; these therapies are sometimes recommended as adjuncts to core treatments. The mechanisms of action for all rehabilitative interventions include contextual factors such as attention and placebo effects. These effects can challenge our interpretation of treatment efficacy from clinical trials, yet also provide opportunities to maximize patient outcomes in clinical practice. When evaluating rehabilitative interventions, the field may benefit from increased emphasis on research that considers contextual factors while evaluating mechanistic, longer-term, clinically-important and policy-relevant outcome measures.

Behavioral cancer pain intervention dosing: results of a Sequential Multiple Assignment Randomized Trial

ABSTRACT

Behavioral pain management interventions are efficacious for reducing pain in patients with cancer. However, optimal dosing of behavioral pain interventions for pain reduction is unknown, and this hinders routine clinical use. A Sequential Multiple Assignment Randomized Trial (SMART) was used to evaluate whether varying doses of Pain Coping Skills Training (PCST) and response-based dose adaptation can improve pain management in women with breast cancer. Participants (N = 327) had stage I-IIIC breast cancer and a worst pain score of > 5/10. Pain severity (a priori primary outcome) was assessed before initial randomization (1:1 allocation) to PCST-Full (5 sessions) or PCST-Brief (1 session) and 5 to 8 weeks later. Responders ( > 30% pain reduction) were rerandomized to a maintenance dose or no dose and nonresponders (<30% pain reduction) to an increased or maintenance dose. Pain severity was assessed again 5 to 8 weeks later (assessment 3) and 6 months later (assessment 4). As hypothesized, PCST-Full resulted in greater mean percent pain reduction than PCST-Brief (M [SD] = -28.5% [39.6%] vs M [SD]= -14.8% [71.8%]; P = 0.041). At assessment 3 after second dosing, all intervention sequences evidenced pain reduction from assessment 1 with no differences between sequences. At assessment 4, all sequences evidenced pain reduction from assessment 1 with differences between sequences ( P = 0.027). Participants initially receiving PCST-Full had greater pain reduction at assessment 4 ( P = 0.056). Varying PCST doses led to pain reduction over time. Intervention sequences demonstrating the most durable decreases in pain reduction included PCST-Full. Pain Coping Skills Training with intervention adjustment based on response can produce sustainable pain reduction.

What are the unsupervised exercise adherence rates in clinical trials for knee osteoarthritis? A systematic review

BACKGROUND

Exercise is an effective intervention for knee osteoarthritis (OA), and unsupervised exercise programs should be a common adjunct to most treatments. However, it is unknown if current clinical trials are capturing information regarding adherence.

OBJECTIVE

To summarize the extent and quality of reporting of unsupervised exercise adherence in clinical trials for knee OA.

METHODS

Reviewers searched five databases (PubMed, CINAHL, Medline (OVID), EMBASE and Cochrane). Randomized controlled trials where participants with knee OA engaged in an unsupervised exercise program were included. The extent to which exercise adherence was monitored and reported was assessed and findings were subgrouped according to method for tracking adherence. The types of adherence measurement categories were synthesized. A quality assessment was completed using the Physiotherapy Evidence Database (PEDro) scores.

RESULTS

Of 3622 abstracts screened, 176 studies met criteria for inclusion. PEDro scores for study quality ranged from two to ten (mean=6.3). Exercise adherence data was reported in 72 (40.9%) studies. Twenty-six (14.8%) studies only mentioned collection of adherence. Adherence rates ranged from 3.7 to 100% in trials that reported adherence. For 18 studies (10.2%) that tracked acceptable adherence, there was no clear superiority in treatment effect based on adherence rates.

CONCLUSIONS

Clinical trials for knee OA do not consistently collect or report adherence with unsupervised exercise programs. Slightly more than half of the studies reported collecting adherence data while only 40.9% reported findings with substantial heterogeneity in tracking methodology. The clinical relevance of these programs cannot be properly contextualized without this information.

Effectiveness of spinal manipulation and biopsychosocial self-management compared to medical care for low back pain: a randomized trial study protocol

BACKGROUND

Chronic low back pain (cLBP) is widespread, costly, and burdensome to patients and health systems. Little is known about non-pharmacological treatments for the secondary prevention of cLBP. There is some evidence that treatments addressing psychosocial factors in higher risk patients are more effective than usual care. However, most clinical trials on acute and subacute LBP have evaluated interventions irrespective of prognosis.

METHODS

We have designed a phase 3 randomized trial with a 2 × 2 factorial design. The study is also a Hybrid type 1 trial with focus on intervention effectiveness while simultaneously considering plausible implementation strategies. Adults (n = 1000) with acute/subacute LBP at moderate to high risk of chronicity based on the STarT Back screening tool will be randomized in to 1 of 4 interventions lasting up to 8 weeks: supported self-management (SSM), spinal manipulation therapy (SMT), both SSM and SMT, or medical care. The primary objective is to assess intervention effectiveness; the secondary objective is to assess barriers and facilitators impacting future implementation. Primary effectiveness outcome measures are: (1) average pain intensity over 12 months post-randomization (pain, numerical rating scale); (2) average low back disability over 12 months post-randomization (Roland-Morris Disability Questionnaire); (3) prevention of cLBP that is impactful at 10-12 months follow-up (LBP impact from the PROMIS-29 Profile v2.0). Secondary outcomes include: recovery, PROMIS-29 Profile v2.0 measures to assess pain interference, physical function, anxiety, depression, fatigue, sleep disturbance, and ability to participate in social roles and activities. Other patient-reported measures include LBP frequency, medication use, healthcare utilization, productivity loss, STarT Back screening tool status, patient satisfaction, prevention of chronicity, adverse events, and dissemination measures. Objective measures include the Quebec Task Force Classification, Timed Up & Go Test, the Sit to Stand Test, and the Sock Test assessed by clinicians blinded to the patients' intervention assignment.

DISCUSSION

By targeting those subjects at higher risk this trial aims to fill an important gap in the scientific literature regarding the effectiveness of promising non-pharmacological treatments compared to medical care for the management of patients with an acute episode of LBP and the prevention of progression to a severe chronic back problem.

Healthcare utilization patterns for knee or hip osteoarthritis before and after changes in national health insurance coverage: A data linkage study

INTRODUCTION

Medical guidelines aim to stimulate stepped care for knee and hip osteoarthritis, redirecting treatments from hospitals to primary care. In the Netherlands, this development was supported by changing health insurance coverage for physio/exercise therapy. The aim of this study was to evaluate healthcare utilization patterns before and after health changes in health insurance coverage.

METHOD

We analyzed electronic health records and claims data from patients with osteoarthritis in the knee (N = 32,091) and hip (N = 16,313). Changes between 2013 and 2019 in the proportion of patients treated by the general practitioner, physio/exercise therapist or orthopedic surgeon within 6 months after onset were assessed.

RESULTS

Joint replacement surgeries decreased for knee (OR 0.47 [0.41-0.54]) and hip (OR 0.81 [0.71-0.93]) osteoarthritis between 2013-2019. The use of physio/exercise therapy increased (knee: OR 1.38 [1.24-1.53], hip: OR 1.26 [1.08-1.47]). However, the proportion treated by a physio/exercise therapist decreased for patients that had not depleted their annual deductibles (knee: OR 0.86 [0.79 - 0.94], hip: OR 0.90 [0.79 - 1.02]). This might be affected by the inclusion of physio/exercise therapy in basic health insurance in 2018.

CONCLUSION

We have found a shift from hospitals to primary care in knee and hip osteoarthritis care. However, the use of physio/exercise therapy declined after changes in insurance coverage for patients that had not depleted their deductibles.

COMMunity of Practice And Safety Support for Navigating Pain (COMPASS-NP): study protocol for a randomized controlled trial with home care workers

BACKGROUND

Chronic pain is a prevalent and costly problem that often has occupational origins. Home care workers (HCWs) are at high risk for work-related injuries, pain, and disability. Current treatments for chronic pain emphasize medications, which are an inadequate stand-alone treatment and can produce significant adverse effects.

METHODS

In this translational study, we will adapt an established work-based injury prevention and health promotion program (COMmunity of Practice And Safety Support: COMPASS) to address the needs of HCWs experiencing chronic pain. COMPASS employs peer-led, scripted group meetings that include educational content, activities, goal setting, and structured social support. The translated intervention, named COMPASS for Navigating Pain (COMPASS-NP), will be delivered in an online group format. Safety protections will be strengthened through an ergonomic self-assessment and vouchers for purchasing ergonomic tools. Educational content will integrate a self-management approach to chronic pain using proven cognitive-behavioral therapy (CBT) principles. We will use a mixed-methods hybrid type 2 evaluation approach to assess effectiveness and implementation. A cluster-randomized waitlist control design will involve 14 groups of 10 HCWs (n = 140) recruited from Washington, Oregon, and Idaho. Half of the groups will be randomly selected to complete the intervention during the first 10 weeks, while the waitlist groups serve as controls. During weeks 10-20, the waitlist groups will complete the intervention while the original intervention groups complete a follow-up period without further intervention. Our primary hypothesis is that COMPASS-NP will reduce pain interference with work and life. Secondary outcomes include injury and pain prevention behaviors, pain severity, changes in medication use, risk for opioid misuse, well-being, physical activity, and sleep. Qualitative data, including phone interviews with group facilitators and organizational partners, will evaluate the implementation and guide dissemination.

DISCUSSION

The results will advance the use and knowledge of secondary prevention interventions such as ergonomic tools and cognitive behavior therapy, to reduce injury, pain, and disability and to encourage appropriate uses of analgesic medications among HCWs.

Feasibility of a theoretically grounded, multicomponent, physiotherapy intervention aiming to promote autonomous motivation to adopt and maintain physical activity in patients with lower-limb osteoarthritis: protocol for a single-arm trial

BACKGROUND

Lower-limb osteoarthritis (OA) causes high levels of pain and disability in adults over 45 years of age. Adopting and maintaining appropriate levels of physical activity (PA) can help patients with lower-limb OA self-manage their symptoms and reduce the likelihood of developing secondary noncommunicable diseases. However, patients with lower-limb OA are less active than people without musculoskeletal pain. This single-arm feasibility trial seeks to determine the feasibility and acceptability of a complex multicomponent physiotherapy behaviour change intervention that aims to aid patients with lower-limb OA to adopt and maintain optimal levels of PA.

METHODS

This trial will be conducted at one site in a National Health Service physiotherapy outpatient setting in the West Midlands of England. Up to thirty-five participants with lower-limb OA will be recruited to receive a physiotherapy intervention of six sessions that aims to optimise their PA levels during phases of behavioural change: adoption, routine formation and maintenance. The intervention is underpinned by self-determination theory (and other motivational frameworks) and seeks to foster a motivationally optimal (empowering) treatment environment and implement behaviour change techniques (BCTs) that target PA behaviours across the three phases of the intervention. Physiotherapists (n = 5-6) will receive training in the why and how of developing a more empowering motivational environment and the delivery of the intervention BCTs. Participants will complete patient-reported and performance-based outcome measures at baseline and 3-month (to reflect behavioural adoption) and 6-month (maintenance) post-baseline. Feasibility and acceptability will be primarily assessed through semi-structured interviews (purposively recruiting participants) and focus groups (inviting all physiotherapists and research staff). Further evaluation will include descriptive analysis of recruitment rates, loss of follow-up and intervention fidelity.

DISCUSSION

A novel complex, multicomponent theoretical physiotherapy behaviour change intervention that aims to create a more empowering motivational treatment environment to assist patients with lower-limb OA to adopt and maintain optimal PA levels has been developed. Testing the feasibility and acceptability of the intervention and its associated physiotherapist training and related trial procedures is required to determine whether a full-scale parallel group (1:1) randomised controlled trial to evaluate the interventions effectiveness in clinical practice is indicated.

Brief self-exercise education for adults with chronic knee pain: A randomized controlled trial

OBJECTIVES

Effective brief instructions for self-management of chronic knee pain are needed.

METHODS

Forty-six participants with chronic knee pain were randomly allocated into two programmes: material-based education alone or brief self-exercise education (brief-See), which comprised a 100-minute instruction for self-exercise combined with compact pain education. Total function (KOOS4, 4-subscale average of knee injury and osteoarthritis outcome score), pain intensity (NRS, numeric rating scale), self-efficacy (PSEQ, pain self-efficacy questionnaire), and health-related quality of life (EQ-5D, European quality of life-5 dimensions) were evaluated at baseline and 4 and 12 weeks after the initial intervention. A generalized mixed linear model estimated average group differences in changes from baseline and 95% confidence intervals (95% CIs) using intention-to-treat principle.

RESULTS

Compared to material-based education alone, the brief-See provided significant additional improvements of 9.4% (95% CI: 2.3 to 16.4) on the KOOS4 and 5.4 points (0.3 to 10.4) on the PSEQ at 12 weeks but did not on the NRS and EQ-5D. Adherence and satisfaction were favourable in the brief-See without any notable adverse event.

CONCLUSIONS

Adding the brief-See to material-based education could be more acceptable and restore total function and self-efficacy, which could contribute to the self-management of chronic knee pain in primary care.

Evidence Review for Preventing Osteoarthritis After an Anterior Cruciate Ligament Injury: An Osteoarthritis Action Alliance Consensus Statement

CONTEXT

The Osteoarthritis Action Alliance formed a secondary prevention task group to develop a consensus on secondary prevention recommendations to reduce the risk of osteoarthritis after a knee injury.

OBJECTIVE

Our goal was to provide clinicians with secondary prevention recommendations that are intended to reduce the risk of osteoarthritis after a person has sustained an anterior cruciate ligament injury. Specifically, this manuscript describes our methods, literature reviews, and dissenting opinions to elaborate on the rationale for our recommendations and to identify critical gaps.

DESIGN

Consensus process.

SETTING

Virtual video conference calls and online voting.

PATIENTS OR OTHER PARTICIPANTS

The Secondary Prevention Task Group consisted of 29 members from various clinical backgrounds.

MAIN OUTCOME MEASURE(S)

The group initially convened online in August 2020 to discuss the target population, goals, and key topics. After a second call, the task group divided into 9 subgroups to draft the recommendations and supportive text for crucial content areas. Twenty-one members completed 2 rounds of voting and revising the recommendations and supportive text between February and April 2021. A virtual meeting was held to review the wording of the recommendations and obtain final votes. We defined consensus as >80% of voting members supporting a proposed recommendation.

RESULTS

The group achieved consensus on 15 of 16 recommendations. The recommendations address patient education, exercise and rehabilitation, psychological skills training, graded-exposure therapy, cognitive-behavioral counseling (lacked consensus), outcomes to monitor, secondary injury prevention, system-level social support, leveraging technology, and coordinated care models.

CONCLUSIONS

This consensus statement reflects information synthesized from an interdisciplinary group of experts based on the best available evidence from the literature or personal experience. We hope this document raises awareness among clinicians and researchers to take steps to mitigate the risk of osteoarthritis after an anterior cruciate ligament injury.

Conversations about mental illness and health in adult audiological rehabilitation

OBJECTIVE

To understand the nature of mental health discussions in audiological rehabilitation, specifically, the types of conversations, when and how they are initiated, and the participant factors associated with discussing mental health.

DESIGN

A cross-sectional descriptive survey including quantitative (multiple choice) and qualitative (free-text) questions regarding mental health discussions between audiologists and clients.

STUDY SAMPLE

A convenience sample of 118 Australian audiologists working in adult audiological rehabilitation.

RESULTS

The majority of participants (95.8%) reported having engaged in discussions with clients about mental illness and health at some point throughout their career. The frequency of these discussions varied across participants: 7% rarely discuss, 50% discuss occasionally, 30% discuss with about half their clients and 13% have discussions with most clients. Many participants (85.6%) reported that clients would initiate these conversations, most often via disclosing the impacts of hearing loss on clients' lives.

CONCLUSIONS

Most audiologists will encounter clients with mental health concerns, and many will engage in conversations about psychological symptoms, therefore, training audiologists to recognise and address verbal and non-verbal cues regarding mental health may help to promote person-centred care and potentially improve outcomes.

Improving diagnosis and treatment of knee osteoarthritis in persons with type 2 diabetes: development of a complex intervention

BACKGROUND

Symptomatic knee osteoarthritis (OA) commonly co-occurs in people with type 2 diabetes (T2DM) and increases the risk for diabetes complications, yet uptake of evidence-based treatment is low. We combined theory, stakeholder involvement and existing evidence to develop a multifaceted intervention to improve OA care in persons with T2DM. This was done in partnership with Arthritis Society Canada to leverage the existing infrastructure and provincial funding for community arthritis care.

METHODS

Each step was informed by a User Advisory Panel of stakeholder representatives, including persons with lived experience. First, we identified the target groups and behaviours through consulting stakeholders and current literature. Second, we interviewed persons living with T2DM and knee OA (n = 18), health professionals (HPs) who treat people with T2DM (n = 18) and arthritis therapists (ATs, n = 18) to identify the determinants of seeking and engaging in OA care (patients), assessing and treating OA (HPs) and considering T2DM in OA treatment (ATs), using the Theoretical Domains Framework (TDF). We mapped the content to behavioural change techniques (BCTs) to identify the potential intervention components. Third, we conducted stakeholder meetings to ascertain the acceptability and feasibility of intervention components, including content and modes of delivery. Fourth, we selected intervention components informed by prior steps and constructed a programme theory to inform the implementation of the intervention and its evaluation.

RESULTS

We identified the barriers and enablers to target behaviours across a number of TDF domains. All stakeholders identified insufficient access to resources to support OA care in people with T2DM. Core intervention components, incorporating a range of BCTs at the patient, HP and AT level, sought to identify persons with knee OA within T2DM care and refer to Arthritis Society Canada for delivery of evidence-based longitudinal OA management. Diverse stakeholder input throughout development allowed the co-creation of an intervention that appears feasible and acceptable to target users.

CONCLUSIONS

We integrated theory, evidence and stakeholder involvement to develop a multifaceted intervention to increase the identification of knee OA in persons with T2DM within diabetes care and improve the uptake and engagement in evidence-based OA management. Our partnership with Arthritis Society Canada supports future spread, scalability and sustainability. We will formally assess the intervention feasibility in a randomized pilot trial.

Does land-based exercise-therapy improve physical activity in people with knee osteoarthritis? A systematic review with meta-analyses

PRIMARY OBJECTIVE

Investigate the effects of land-based exercise-therapy on physical activity in people with knee osteoarthritis (KOA).

DESIGN

Systematic review and meta-analysis of randomised or quasi-randomised trials investigating land-based exercise-therapy on physical activity, fitness, and general health in people with KOA. We updated a 2013 Cochrane review search on exercise-therapy for KOA in April 2021 and applied the Cochrane Risk-of-Bias Tool 1.0 to included articles. Standardised mean differences (SMDs) and 95% confidence intervals (CI) were calculated. GRADE was used to assess certainty of the evidence.

RESULTS

Twenty-eight randomised controlled trials (2,789 participants) evaluating the effects of resistance-training (n = 10), walking (n = 6) and mixed-exercise programs (n = 7) were identified. Low to moderate certainty evidence indicated small increases in physical activity for exercise-therapy compared to non-exercise interventions in the short-term (SMD, 95% CI = 0.29, 0.09 to 0.50), but not the medium- (0.03, -0.11 to 0.18) or long-term (-0.06, -0.34 to 0.22). Low certainty evidence indicated large increases in physical activity for walking programs (0.53, 0.11 to 0.95) and mixed-exercise programs (0.67, 0.37 to 0.97) compared to non-exercise interventions in the short-term. Low certainty evidence indicated moderate and small increases in physical activity for resistance-training combined with education focused on pain coping skills and self-efficacy compared to education alone at medium-term follow-up (0.45, 0.19 to 0.71).

CONCLUSION

Walking and mixed-exercise, but not resistance-training, may improve physical activity in people with KOA in the short-term. Combining resistance-training with education may increase physical activity in the medium-, but not the long-term, highlighting the potential importance of developing more effective longer-term interventions for people with KOA. Future studies evaluating land-based exercise-therapy are encouraged to include physical activity outcomes and longer-term follow-up to increase the certainty of evidence.

Adjunctive therapies in addition to land-based exercise therapy for osteoarthritis of the hip or knee

BACKGROUND

Land-based exercise therapy is recommended in clinical guidelines for hip or knee osteoarthritis. Adjunctive non-pharmacological therapies are commonly used alongside exercise in hip or knee osteoarthritis management, but cumulative evidence for adjuncts to land-based exercise therapy is lacking.

OBJECTIVES

To evaluate the benefits and harms of adjunctive therapies used in addition to land-based exercise therapy compared with placebo adjunctive therapy added to land-based exercise therapy, or land-based exercise therapy only for people with hip or knee osteoarthritis.

SEARCH METHODS

We searched CENTRAL, MEDLINE, PsycINFO, EMBASE, CINAHL, Physiotherapy Evidence Database (PEDro) and clinical trials registries up to 10 June 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) or quasi-RCTs of people with hip or knee osteoarthritis comparing adjunctive therapies alongside land-based exercise therapy (experimental group) versus placebo adjunctive therapies alongside land-based exercise therapy, or land-based exercise therapy (control groups). Exercise had to be identical in both groups. Major outcomes were pain, physical function, participant-reported global assessment, quality of life (QOL), radiographic joint structural changes, adverse events and withdrawals due to adverse events. We evaluated short-term (6 months), medium-term (6 to 12 months) and long-term (12 months onwards) effects.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study eligibility, extracted data, and assessed risk of bias and certainty of evidence for major outcomes using GRADE.

MAIN RESULTS

We included 62 trials (60 RCTs and 2 quasi-RCTs) totalling 6508 participants. One trial included people with hip osteoarthritis, one hip or knee osteoarthritis and 59 included people with knee osteoarthritis only. Thirty-six trials evaluated electrophysical agents, seven manual therapies, four acupuncture or dry needling, or taping, three psychological therapies, dietary interventions or whole body vibration, two spa or peloid therapy and one foot insoles. Twenty-one trials included a placebo adjunctive therapy. We presented the effects stratified by different adjunctive therapies along with the overall results. We judged most trials to be at risk of bias, including 55% at risk of selection bias, 74% at risk of performance bias and 79% at risk of detection bias. Adverse events were reported in eight (13%) trials. Comparing adjunctive therapies plus land-based exercise therapy against placebo therapies plus exercise up to six months (short-term), we found low-certainty evidence for reduced pain and function, which did not meet our prespecified threshold for a clinically important difference. Mean pain intensity was 5.4 in the placebo group on a 0 to 10 numerical pain rating scale (NPRS) (lower scores represent less pain), and 0.77 points lower (0.48 points better to 1.16 points better) in the adjunctive therapy and exercise therapy group; relative improvement 10% (6% to 15% better) (22 studies; 1428 participants). Mean physical function on the Western Ontario and McMaster (WOMAC) 0 to 68 physical function (lower scores represent better function) subscale was 32.5 points in the placebo group and reduced by 5.03 points (2.57 points better to 7.61 points better) in the adjunctive therapy and exercise therapy group; relative improvement 12% (6% better to 18% better) (20 studies; 1361 participants). Moderate-certainty evidence indicates that adjunctive therapies did not improve QOL (SF-36 0 to 100 scale, higher scores represent better QOL). Placebo group mean QOL was 81.8 points, and 0.75 points worse (4.80 points worse to 3.39 points better) in the placebo adjunctive therapy group; relative improvement 1% (7% worse to 5% better) (two trials; 82 participants). Low-certainty evidence (two trials; 340 participants) indicates adjunctive therapies plus exercise may not increase adverse events compared to placebo therapies plus exercise (31% versus 13%; risk ratio (RR) 2.41, 95% confidence interval (CI) 0.27 to 21.90). Participant-reported global assessment was not measured in any studies. Compared with land-based exercise therapy, low-certainty evidence indicates that adjunctive electrophysical agents alongside exercise produced short-term (0 to 6 months) pain reduction of 0.41 points (0.17 points better to 0.63 points better); mean pain in the exercise-only group was 3.8 points and 0.41 points better in the adjunctive therapy plus exercise group (0 to 10 NPRS); relative improvement 7% (3% better to 11% better) (45 studies; 3322 participants). Mean physical function (0 to 68 WOMAC subscale) was 18.2 points in the exercise group and 2.83 points better (1.62 points better to 4.04 points better) in the adjunctive therapy plus exercise group; relative improvement 9% (5% better to 13% better) (45 studies; 3323 participants). These results are not clinically important. Mean QOL in the exercise group was 56.1 points and 1.04 points worse in the adjunctive therapies plus exercise therapy group (1.04 points worse to 3.12 points better); relative improvement 2% (2% worse to 5% better) (11 studies; 1483 participants), indicating no benefit (low-certainty evidence). Moderate-certainty evidence indicates that adjunctive therapies plus exercise probably result in a slight increase in participant-reported global assessment (short-term), with success reported by 45% in the exercise therapy group and 17% more individuals receiving adjunctive therapies and exercise (RR 1.37, 95% CI 1.15 to 1.62) (5 studies; 840 participants). One study (156 participants) showed little difference in radiographic joint structural changes (0.25 mm less, 95% CI -0.32 to -0.18 mm); 12% relative improvement (6% better to 18% better). Low-certainty evidence (8 trials; 1542 participants) indicates that adjunctive therapies plus exercise may not increase adverse events compared with exercise only (8.6% versus 6.5%; RR 1.33, 95% CI 0.78 to 2.27).

AUTHORS' CONCLUSIONS

Moderate- to low-certainty evidence showed no difference in pain, physical function or QOL between adjunctive therapies and placebo adjunctive therapies, or in pain, physical function, QOL or joint structural changes, compared to exercise only. Participant-reported global assessment was not reported for placebo comparisons, but there is probably a slight clinical benefit for adjunctive therapies plus exercise compared with exercise, based on a small number of studies. This may be explained by additional constructs captured in global measures compared with specific measures. Although results indicate no increased adverse events for adjunctive therapies used with exercise, these were poorly reported. Most studies evaluated short-term effects, with limited medium- or long-term evaluation. Due to a preponderance of knee osteoarthritis trials, we urge caution in extrapolating the findings to populations with hip osteoarthritis.

Comparative effect of two educational videos on self-efficacy and kinesiophobia in people with knee osteoarthritis: an online randomised controlled trial

OBJECTIVE

To compare change in self-efficacy for managing knee osteoarthritis (OA) pain and kinesiophobia after watching an educational video based on an empowerment and participatory discourse with a video based on a disease and impairment discourse.

DESIGN

Two-arm randomised controlled trial with participants aged ≥45 years with knee pain (n = 589). Participants completed both baseline and follow-up outcomes and watched one randomly-allocated video (12-minute duration) during one 30-45-minute session within a single online survey. The experimental video presented evidence-based knee OA information using design and language that aimed to empower people and focus on activity participation to manage OA, while the control video presented similar information but with a disease and impairment focus. Primary outcome measures were Arthritis Self-Efficacy Scale pain subscale (range 0-10) and Brief Fear of Movement Scale for OA (range 6-24). Secondary outcomes were expectations about prognosis and physical activity benefits, perceived importance and motivation to be physically active, knee OA knowledge, hopefulness for the future, level of concern and perceived need for surgery.

RESULTS

Compared to control (n = 293), the experimental group (n = 296) showed improved self-efficacy for managing OA pain (mean difference 0.4 [95%CI 0.2, 0.6] units) and reduced kinesiophobia (1.6 [1.1, 2.0] units). The experimental group also demonstrated greater improvements in all secondary outcomes apart from hopefulness, which was high in both groups.

CONCLUSION

An educational video based on an empowerment and participatory discourse improved pain self-efficacy and reduced kinesiophobia in people with knee OA more than a video based on a disease and impairment discourse.

A systematic review of economic analyses of psychological interventions and therapies in health-related settings

Background

This review aims to synthesise evidence on the economic impact of psychological interventions and therapies when applied to a broad range of physical health conditions.

Methods

The following bibliographic databases were searched for relevant articles: MEDLINE (Ovid), EMBASE (Ovid) and PsycINFO (Ebsco). As this review was intended to update an earlier review, the date range for the search was restricted to between January 2012 and September 2018. Reference lists from the review articles were also searched for relevant articles. Study quality was evaluated using the Scottish Intercollegiate Network Guidelines (SIGN) appraisal checklists for both economic studies and Randomised Controlled Trials (RCTs). When the economic analyses did not provide sufficient detail for quality evaluation, the original RCT papers were sought and these were also evaluated. Half of the papers were quality rated by a second author. Initial agreement was high and all disagreements were resolved by discussion.

Results

This yielded 1408 unique articles, reduced to 134 following screening of the title and abstract. The full texts of the remaining articles were reviewed by at least one team member and all exclusions were discussed and agreed by the team. This left 46 original research articles, alongside five systematic reviews. Fifty-seven per cent of the articles were deemed to be of high quality, with the remainder of acceptable quality. Fifteen different medical conditions were covered, with chronic pain (10 articles) and cancer (9 articles) being the two most investigated health conditions. Three quarters of the papers reviewed showed evidence for the cost-effectiveness of psychological interventions in physical health, with the clearest evidence being in the field of chronic pain and cancer.

Conclusions

This paper provides a comprehensive integration of the research on the cost-effectiveness of psychological therapies in physical health. Whilst the evidence for cost-effectiveness in chronic pain and cancer is encouraging, some health conditions require further study. Clearly, as the primary research is international, and was therefore conducted across varying health care systems, caution must be exercised when applying the results to counties outside of those covered. Despite this, the results are of potential relevance to service providers and funders.

Depression Screening and Behavioral Health Integration in Musculoskeletal Trauma Care

OBJECTIVES

To report our experiences in implementing a behavioral health integration pathway, including a validated depression screening and referral to care.

DESIGN

Retrospective case series.

SETTING

Single surgeon's musculoskeletal trauma outpatient practice during calendar year 2019.

PATIENTS

All patients presenting to the practice during 2019 were included (n = 573).

INTERVENTION

We piloted the usage of Patient Health Questionnaire (PHQ)-2 and PHQ-9 screening. An evidence-based, real-time treatment protocol embedded in the electronic health record was triggered when a patient screened positive for depression including an automated behavioral health integration pathway.

MAIN OUTCOME MEASUREMENTS

The percentage of patients screened, the results of the PHQ screening, and the number of patients referred and enrolled in behavioral health programs were collected.

RESULTS

Of the 573 patients, 476 (83%) received the PHQ-2 screening, 80 (14%) had a current screening on file (within 1 year), and 17 (3.0%) were not screened. One hundred seventy-two patients (36%) had a PHQ-2 score of 2 or greater and completed the PHQ-9; of them, 60 (35% of patients screened with full PHQ-9, 13% of patients screened) screened positive for symptoms of moderate depression (PHQ-9 score ≥10), and 19 (4.0%) reported passive suicidal ideation (PHQ-9 item 9). Fifty of these patients were referred to behavioral health through the pathway, and 8 patients enrolled in the program. Ten patients were not referred because of a technical error that was quickly resolved. Patients reporting suicidal ideation were managed with psychiatric crisis resources including immediate virtual consult in the examination room.

CONCLUSIONS

This case series demonstrates the feasibility of screening patients for depressive symptoms and making necessary referrals to behavioral health in outpatient musculoskeletal trauma care. We identified 50 patients with depression and appropriately triaged them for further care in our community.

Therapeutic potential of nanotechnology-based approaches in osteoarthritis

Osteoarthritis (OA) is a multifactorial disease that affects the entire joint, often resulting in severe pain, disability, psychological distress, and a lower quality of life. Patient self-management is emphasized in OA clinical recommendations. Currently, the clinical treatment of OA mainly focuses on pain relief and the improvement of joint function, with few options for regenerating degenerative cartilage or slowing the progression of OA. Therefore, we first reviewed the current treatment of OA, and then summarized the research advances of nanotechnology in OA treatment, including nano drug delivery systems for small molecule drugs, nucleic acids and proteins, nano-scaffolds for cartilage regeneration, and nanoparticle lubricants. Finally, we discussed the opportunities and potential challenges of nanotechnology in OA treatment.

Knee Osteoarthritis Education Interventions in Published Trials Are Typically Unclear, Not Comprehensive Enough, and Lack Robust Development: Ancillary Analysis of a Systematic Review

OBJECTIVE

To summarize the content, development, and delivery of education interventions in clinical trials for people with knee osteoarthritis (OA).

DESIGN

Ancillary analysis of a systematic review.

LITERATURE SEARCH

MEDLINE, EMBASE, SPORTDiscus, CINAHL, and Web of Science were searched from inception to April 2020.

STUDY SELECTION CRITERIA

Randomized controlled trials involving patient education for people with knee OA.

DATA SYNTHESIS

Content of education interventions was matched against a predefined topic list (n = 14) and categorized as accurate and clear, partially accurate/lacks clarity, or not reported. We examined whether education interventions included skill development or stated learning objectives and if they were developed based on theory, previous research, or codesign principles. Delivery methods and mode(s) were also identified. Data were summarized descriptively.

RESULTS

Thirty-eight education interventions (30 trials) were included. Interventions lacked comprehensiveness (median topics per intervention = 3/14, range = 0-11). Few topics were accurately and clearly described (10%, 13/136). Sixty-one percent (n = 23/38) of interventions targeted skill development, and 34% (n = 13/38) identified learning objectives. Forty-two percent (n = 16/38) were based on theory; 45% (n = 17/38) were based on research for chronic conditions, including 32% (n = 12/38) based on OA. Eleven percent of interventions (n = 4/38) were codesigned. Education was typically facilitated through face-to-face sessions (median = 9, range = 0-55), supplemented with telephone calls and/or written materials.

CONCLUSION

Education interventions for people with knee OA lacked comprehensiveness plus accurate and clear descriptions of topics covered. Most interventions failed to identify learning objectives and were not based on theory, previous research, or codesign principles. J Orthop Sports Phys Ther 2022;52(5):276-286.

Effectiveness of Interventions Based on Pain Neuroscience Education on Pain and Psychosocial Variables for Osteoarthritis: A Systematic Review

Osteoarthritis (OA) is the most common joint condition. It affects more than 300 million people worldwide, who suffer from pain and physical disability. Objective: To determine the results of cognitive educational interventions for pain management and psychosocial variables in adults with OA. Method: A systematic review was conducted based on searches in MEDLINE, OVID, LILACS, Scopus, PEDro, OTseeker, The Cochrane Library, EBSCO, and Google Scholar. The search strategy included the main terms neuroscience education and osteoarthritis, without any re-strictions with regard to dates or study type (PROSPERO register CRD42021222763). Results: We included four articles that implemented the intervention in 1–6 sessions, addressing concepts related to goal orientation and providing strategies for understanding pain. The results suggest that there is an improvement between the groups (PNE) when compared, but this cannot necessarily be attributed to pain neuroscience education (PNE), as small effect sizes for variables such as pain catastrophizing and kinesiophobia were observed. The response in the modulation of acute pain following the surgical procedure may produce a variation in the responses and this may be mediated by medications. Conclusion: The study revealed an improvement in favor of the groups managed with PNE, although more studies documenting the topic are warranted.

From Fear to Safety: A Roadmap to Recovery From Musculoskeletal Pain

Contemporary conceptualizations of pain emphasize its protective function. The meaning assigned to pain drives cognitive, emotional, and behavioral responses. When pain is threatening and a person lacks control over their pain experience, it can become distressing, self-perpetuating, and disabling. Although the pathway to disability is well established, the pathway to recovery is less researched and understood. This Perspective draws on recent data on the lived experience of people with pain-related fear to discuss both fear and safety-learning processes and their implications for recovery for people living with pain. Recovery is here defined as achievement of control over pain as well as improvement in functional capacity and quality of life. Based on the common-sense model, this Perspective proposes a framework utilizing Cognitive Functional Therapy to promote safety learning. A process is described in which experiential learning combined with "sense making" disrupts a person's unhelpful cognitive representation and behavioral and emotional response to pain, leading them on a journey to recovery. This framework incorporates principles of inhibitory processing that are fundamental to pain-related fear and safety learning.

Complex Lifestyle and Psychological Intervention in Knee Osteoarthritis: Scoping Review of Randomized Controlled Trials

Knee osteoarthritis (OA) causes pain, disability and poor quality of life in the elderly. The primary aim was to identify and map out the current evidence for randomised controlled trials (RCTs) on complex lifestyle and psychosocial interventions for knee OA. The secondary aim was to outline different components of complex lifestyle and psychosocial interventions. Our scoping review searched five databases from 2000 to 2021 where complex lifestyle or psychosocial interventions for patients with knee OA were compared to other interventions. Screening and data extraction were performed by two review authors independently and discrepancies resolved through consensus and in parallel with a third reviewer. A total of 38 articles were selected: 9 studied the effectiveness of psychological interventions; 11 were on self-management and lifestyle interventions; 18 looked at multifaceted interventions. This review highlights the substantial variation in knee OA interventions and the overall lack of quality in the current literature. Potential areas of future research, including identifying prognostic social factors, stratified care models, transdisciplinary care delivery and technology augmented interventions, have been identified. Further high-quality RCTs utilizing process evaluations and economic evaluation in accordance with the MRC guidelines are critical for the development of evidence-based knee OA programs globally.

Training of Physical Therapists to Deliver Individualized Biopsychosocial Interventions to Treat Musculoskeletal Pain Conditions: A Scoping Review

OBJECTIVE

Current guidelines recommend management of musculoskeletal pain conditions from a biopsychosocial approach; however, biopsychosocial interventions delivered by physical therapists vary considerably in effectiveness. It is unknown whether the differences are explained by the intervention itself, the training and/or competency of physical therapists delivering the intervention, or fidelity of the intervention. The aim was to investigate and map the training, competency assessments, and fidelity checking of individualized biopsychosocial interventions delivered by physical therapists to treat musculoskeletal pain conditions.

METHODS

A scoping review methodology was employed, using Arksey and O'Malley's framework. Seven electronic databases were searched between January and March 2019, with a bridge search completed in January 2020. Full-text peer-reviewed articles, with an individualized biopsychosocial intervention were considered, and 35 studies were included.

RESULTS

Reporting overall was sparse and highly variable. There was a broad spectrum of training. More sophisticated training involved workshops combining didactic and experiential learning over longer durations with supervision and feedback. Less sophisticated training was brief, involving lectures or seminars, with no supervision or feedback. Competency assessments and fidelity testing were underperformed.

CONCLUSIONS

Training in some interventions might not have facilitated the implementation of skills or techniques to enable the paradigm shift and behavior change required for physical therapists to effectively deliver a biopsychosocial intervention. Lack of competency assessments and fidelity checking could have impacted the methodological quality of biopsychosocial interventions.

IMPACT

This study highlighted problematic reporting, training, assessment of competency, and fidelity checking of physical therapist-delivered individualized biopsychosocial interventions. Findings here highlight why previous interventions could have shown small effect sizes and point to areas for improvement in future interventions. These findings can help inform future research and facilitate more widespread implementation of physical therapist-delivered biopsychosocial interventions for people with musculoskeletal pain and thereby improve their quality of life.

Effects of a physiotherapist-led approach based on a biopsychosocial model for spinal disorders: protocol for a systematic review

INTRODUCTION

Low back pain and neck pain are among the most common musculoskeletal disorders, and their related medical costs are rising every year. Many interventions are based on the biopsychosocial (BPS) model since the cause of pain is more multifaceted. Physiotherapists have increased opportunities to perform multidisciplinary interventions alone in clinical practice due to a lack of understanding of the model and its cost. Therefore, physiotherapist-led interventions using the BPS model are important and require an updated report summarising their effectiveness. Thus, the purpose of this study will be to summarise and synthesise the effects of physiotherapist-led interventions using the BPS model for spinal disorders.

METHODS AND ANALYSIS

We will search the Web of Science, CENTRAL, MEDLINE, PsycINFO, CINAHL and PEDro electronic databases, using a date range from inception to September 2021. We will include only randomised controlled trials for patients diagnosed with spinal disorders who received physiotherapist-led interventions based on the BPS model. The search will be limited to English-language publications. Pain intensity and disability are the primary outcomes. Secondary outcomes are any psychological factors. We will examine the short-term, medium-term and long-term effects, and a subgroup analysis will be conducted, if possible, to investigate the role of additional physiotherapist training.

ETHICS AND DISSEMINATION

This study is exempt from ethical approval because it involves publicly available documents. The findings will be submitted for publication in a relevant peer-reviewed journal.

Screening for Yellow Flags in Orthopaedic Physical Therapy: A Clinical Framework

BACKGROUND

Psychological factors influence or are associated with physical function, pain, and health care costs among individuals with musculoskeletal pain conditions. Recent clinical practice guidelines recommend screening for psychological factors (also referred to as "yellow flags") in physical therapy practice to help understand prognosis and inform shared decision making for treatment.

CLINICAL QUESTION

Despite the urgings of clinical practice guidelines and evidence of the influence of psychological factors on clinical outcomes, screening for yellow flags is uncommon in clinical practice. Clinicians may feel uncertain about how to integrate screening tools into clinical practice, and how screening results might inform decision making and care coordination.

KEY RESULTS

We outline a 3-step framework for routine yellow flag screening in physical therapy practice: (1) establish a standard first-line screening instrument and process, (2) interpret the results to inform shared decision making, and (3) monitor treatment progress. Four case examples illustrate how yellow flag screening can help clinicians and patients decide whether the patient might benefit most from standard physical therapy, psychologically informed physical therapy, psychologically informed physical therapy with referral to another health care provider, or immediate referral.

CLINICAL APPLICATION

Consider incorporating a standard yellow flag screening process into usual musculoskeletal health care. We present a framework to guide yellow flag screening in practice (1) to help inform treatment pathway selection and (2) to enhance interdisciplinary communication. J Orthop Sports Phys Ther 2021;51(9):459-469. doi:10.2519/jospt.2021.10570.

Back and neck pain: in support of routine delivery of non-pharmacologic treatments as a way to improve individual and population health

Chronic back and neck pain are highly prevalent conditions that are among the largest drivers of physical disability and cost in the world. Recent clinical practice guidelines recommend use of non-pharmacologic treatments to decrease pain and improve physical function for individuals with back and neck pain. However, delivery of these treatments remains a challenge because common care delivery models for back and neck pain incentivize treatments that are not in the best interests of patients, the overall health system, or society. This narrative review focuses on the need to increase use of non-pharmacologic treatment as part of routine care for back and neck pain. First, we present the evidence base and summarize recommendations from clinical practice guidelines regarding non-pharmacologic treatments. Second, we characterize current use patterns for non-pharmacologic treatments and identify potential barriers to their delivery. Addressing these barriers will require coordinated efforts from multiple stakeholders to prioritize evidence-based non-pharmacologic treatment approaches over low value care for back and neck pain. These stakeholders include patients, health care providers, health care organizations, administrators, payers, policymakers and researchers.

Construct validity of the OCTOPuS stratification algorithm for allocating patients with knee osteoarthritis into subgroups

BACKGROUND

We recently developed a model of stratified exercise therapy, consisting of (i) a stratification algorithm allocating patients with knee osteoarthritis (OA) into one of the three subgroups ('high muscle strength subgroup' representing a post-traumatic phenotype, 'low muscle strength subgroup' representing an age-induced phenotype, and 'obesity subgroup' representing a metabolic phenotype) and (ii) subgroup-specific exercise therapy. In the present study, we aimed to test the construct validity of this algorithm.

METHODS

Data from five studies (four exercise therapy trial cohorts and one cross-sectional cohort) were used to test the construct validity of our algorithm by 63 a priori formulated hypotheses regarding three research questions: (i) are the proportions of patients in each subgroup similar across cohorts? (15 hypotheses); (ii) are the characteristics of each of the subgroups in line with their proposed underlying phenotypes? (30 hypotheses); (iii) are the effects of usual exercise therapy in the 3 subgroups in line with the proposed effect sizes? (18 hypotheses).

RESULTS

Baseline data from a total of 1211 patients with knee OA were analyzed for the first and second research question, and follow-up data from 584 patients who were part of an exercise therapy arm within a trial for the third research question. In total, the vast majority (73%) of the hypotheses were confirmed. Regarding our first research question, we found similar proportions in each of the three subgroups across cohorts, especially for three cohorts. Regarding our second research question, subgroup characteristics were almost completely in line with the proposed underlying phenotypes. Regarding our third research question, usual exercise therapy resulted in similar, medium to large effect sizes for knee pain and physical function for all three subgroups.

CONCLUSION

We found mixed results regarding the construct validity of our stratification algorithm. On the one hand, it is a valid instrument to consistently allocate patients into subgroups that aligned our hypotheses. On the other hand, in contrast to our hypotheses, subgroups did not differ substantially in effects of usual exercise therapy. An ongoing trial will assess whether this algorithm accompanied by subgroup-specific exercise therapy improves clinical and economic outcomes.

Patient education improves pain and function in people with knee osteoarthritis with better effects when combined with exercise therapy: a systematic review

QUESTION

Is patient education effective as a standalone intervention or combined with other interventions for people with knee osteoarthritis?

DESIGN

Systematic review of randomised controlled trials. MEDLINE, EMBASE, SPORTDiscus, CINAHL and Web of Science were searched from inception to April 2020. The Cochrane Risk of Bias tool was used for included studies, and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to interpret certainty of results.

PARTICIPANTS

People with knee osteoarthritis.

INTERVENTION

Any patient education intervention compared with any non-pharmacological comparator.

OUTCOME MEASURES

Primary outcomes were self-reported pain and function.

RESULTS

Twenty-nine trials involving 4,107 participants were included, informing low to very-low certainty evidence. Nineteen of 28 (68%) pooled comparisons were not statistically significant. Patient education was superior to usual care for pain (SMD -0.35, 95% CI -0.56 to -0.14) and function in the short term (-0.31, 95% CI -0.62 to 0.00), but inferior to exercise therapy for pain in the short term (0.77, 95% CI 0.07 to 1.47). Combining patient education with exercise therapy produced superior outcomes compared with patient education alone for pain in the short term (0.44, 95% CI 0.19 to 0.69) and function in the short (0.81, 95% CI 0.54 to 1.08) and medium term (0.39, 95% CI 0.15 to 0.62). When using the Western Ontario and McMaster Universities Osteoarthritis Index for these comparisons, clinically important differences indicated that patient education was inferior to exercise therapy for pain in the short term (MD 1.56, 95% CI 0.14 to 2.98) and the combination of patient education and exercise therapy for function in the short term (8.94, 95% CI 6.05 to 11.82).

CONCLUSION

Although patient education produced statistically superior short-term pain and function outcomes compared with usual care, differences were small and may not be clinically important. Patient education should not be provided as a standalone treatment and should be combined with exercise therapy to provide statistically superior and clinically important short-term improvements in function compared with education alone.

A new integrated behavioural intervention for knee osteoarthritis: development and pilot study

Background

Exercise-based approaches have been a cornerstone of physiotherapy management of knee osteoarthritis for many years. However, clinical effects are considered small to modest and the need for continued adherence identified as a barrier to clinical efficacy. While exercise-based approaches focus on muscle strengthening, biomechanical research has identified that people with knee osteoarthritis over activate their muscles during functional tasks. Therefore, we aimed to create a new behavioural intervention, which integrated psychologically informed practice with biofeedback training to reduce muscle overactivity, and which was suitable for delivery by a physiotherapist.

Methods

Through literature review, we created a framework linking theory from pain science with emerging biomechanical concepts related to overactivity of the knee muscles. Using recognised behaviour change theory, we then mapped a set of intervention components which were iteratively developed through ongoing testing and consultation with patients and physiotherapists.

Results

The underlying framework incorporated ideas related to central sensitisation, motor responses to pain and also focused on the idea that increased knee muscle overactivity could result from postural compensation. Building on these ideas, we created an intervention with five components: making sense of pain, general relaxation, postural deconstruction, responding differently to pain and functional muscle retraining. The intervention incorporated a range of animated instructional videos to communicate concepts related to pain and biomechanical theory and also used EMG biofeedback to facilitate visualization of muscle patterns. User feedback was positive with patients describing the intervention as enabling them to “create a new normal” and to be “in control of their own treatment.” Furthermore, large reductions in pain were observed from 11 patients who received a prototype version of the intervention.

Conclusion

We have created a new intervention for knee osteoarthritis, designed to empower individuals with capability and motivation to change muscle activation patterns and beliefs associated with pain. We refer to this intervention as Cognitive Muscular Therapy. Preliminary feedback and clinical indications are positive, motivating future large-scale trials to understand potential efficacy. It is possible that this new approach could bring about improvements in the pain associated with knee osteoarthritis without the need for continued adherence to muscle strengthening programmes.

The comfort ability program for adolescents with sickle cell pain: Evaluating feasibility and acceptability of an inpatient group-based clinical implementation

BACKGROUND

Integration of nonpharmacological therapies, such as cognitive and behavioral pain management strategies, is recommended to support comprehensive disease and pain management among children and adolescents with sickle cell disease (SCD). The Comfort Ability Program for Sickle Cell Pain (CAP for SCP) introduces psychological and biobehavioral pain management strategies to children and adolescents with SCD. This study aimed to pilot the implementation of the CAP for SCP in a group setting to children and adolescents hospitalized for SCD pain examining feasibility, acceptability, and preliminary effectiveness on improving pain knowledge and coping efficacy.

METHOD

Adaptation of CAP for SCP into a three-session group format was guided by four phases of the Dynamic Adaptation Process model: Exploration, Preparation, Implementation, and Sustainment. Youth with SCD (n = 57) hospitalized for pain participated in at least one session and completed self-report of knowledge of pain management skills, pain coping efficacy, and treatment acceptance. Completion rates of sessions and qualitative feedback were gathered to evaluate feasibility and acceptability.

RESULTS

Feasibility of conducting inpatient group sessions was suboptimal; however, patients and medical providers reported moderate to high levels of treatment acceptance. Patients also reported significant improvements in knowledge of pain management skills following session 1.

CONCLUSIONS

CAP for SCP is a patient-centered first-line psychoeducational intervention that can be integrated into clinical practice settings to introduce youth to cognitive and behavioral pain management strategies to support SCD pain management.

A probiotic intervention on pain hypersensitivity and microbiota composition in patients with osteoarthritis pain: Study protocol for a randomized controlled trial

OBJECTIVES

This study aims to examine the effects of probiotics on pain hypersensitivity at the end of a six-week intervention program in patients with osteoarthritis (OA)-related pain.

PATIENTS AND METHODS

This double-blind randomized controlled clinical trial with two parallel arms will be conducted between January 2021 and July 2022. At least 30 participants (age range, 50 to 90 years) of both sexes with a diagnosis of symptomatic hip or knee (Kellgren-Lawrence scale ≥3) will be recruited in each arm (total n=60) to achieve adequate statistical power in the analyses. The intervention will be administered for six weeks followed by a four-week follow-up period. The experimental group will receive a probiotic product plus the usual medical care. The control group will receive a probiotical sham plus the usual medical care. Assessment points will be measured at baseline, end of intervention, and one-month post-intervention. The outcomes of this intervention will be a change in visual analog scale pain and the gut microbiota composition. Group by time effects will be compared using mixed-model analysis of variance.

CONCLUSION

A reduction in pain hypersensitivity in patients with knee OA-related pain could suggest an involvement of microbiota, or part of it, in chronic pain state mechanisms.

Are education, exercise and diet interventions a cost-effective treatment to manage hip and knee osteoarthritis? A systematic review

OBJECTIVE

To identify research gaps and inform implementation we systematically reviewed the literature evaluating cost-effectiveness of recommended treatments (education, exercise and diet) for the management of hip and/or knee OA.

METHODS

We searched Medline, Embase, Cochrane Central Register of Controlled Trials, National Health Services Economic Evaluation Database, and EconLit from inception to November 2019 for trial-based economic evaluations investigating hip and/or knee OA core treatments. Two investigators screened relevant publications, extracted data and synthesized results. Risk of bias was assessed using the Consensus on Health Economic Criteria list.

RESULTS

Two cost-minimization, five cost-effectiveness and 16 cost-utility analyses evaluated core treatments in six health systems. Exercise therapy with and without education or diet was cost-effective or cost-saving compared to education or physician-delivered usual care at conventional willingness to pay (WTP) thresholds in 15 out of 16 publications. Exercise interventions were cost-effective compared to physiotherapist-delivered usual care in three studies at conventional WTP thresholds. Education interventions were not cost-effective compared to usual care or placebo at conventional WTP thresholds in three out of four publications.

CONCLUSIONS

Structured core treatment programs were clinically effective and cost-effective, compared to physician-delivered usual care, in five health care systems. Providing education about core treatments was not consistently cost-effective. Implementing structured core treatment programs into funded clinical pathways would likely be an efficient use of health system resources and enhance physician-delivered usual primary care.

Associations of the modified STarT back tool and Hospital Anxiety and Depression Scale (HADS) with gait speed and knee pain in knee osteoarthritis: a retrospective cohort study

OBJECTIVE

The association of the modified STarT Back Tool (mSBT) psychosocial measure with gait speed and knee pain in knee osteoarthritis is not well defined. This study aimed to, in patients with knee osteoarthritis, (i) examine the convergent validity of mSBT with the Hospital Anxiety and Depression Scale (HADS) and (ii) compare the predictive validity of mSBT and HADS with gait speed and knee pain.

METHODS

We performed a retrospective cohort analysis of mSBT, HADS, gait speed, and knee pain outcomes data collected from 119 patients who received outpatient physical therapy. Of these patients who were evaluated at their first (baseline) physical therapy visit, 55 had available data at the Week-16 follow-up visit.

RESULTS

mSBT and HADS showed moderately strong pairwise correlations (Spearman correlation > 0.57; p < 0.001). After adjusting for age, sex, body weight, and knee impairment variables in multivariable linear mixed-effects analyses, mSBT was associated with gait speed (p < 0.001) and knee pain intensity (p < 0.001) and it had comparable strength of association as HADS. In within-patient regression analyses, change in mSBT was associated with changes in gait speed (p = 0.04) and knee pain (p = 0.01) over 16 weeks.

CONCLUSION

The mSBT had convergent validity with HADS and it showed predictive validity with gait speed and knee pain in knee osteoarthritis. Although broader validation is required, the 5-item mSBT psychosocial measure may be applied as part of routine clinical care to assess psychological distress in patients with knee osteoarthritis. IMPLICATIONS FOR REHABILITATION The 5-item psychosocial subscale of the modified STarT Back tool (mSBT) showed good convergent validity with the 14-item Hospital Anxiety and Depression Scale in patients with knee osteoarthritis. The mSBT psychosocial subscale showed predictive validity, at both cross-sectional and longitudinal levels, with gait speed and knee pain in patients with knee osteoarthritis. The mSBT can potentially be used in the busy clinical setting to assess psychological distress in patients with knee osteoarthritis.

A proof-of-concept study on the impact of a chronic pain and physical activity training workshop for exercise professionals

OBJECTIVES

Physical activity is essential for long-term chronic pain management, yet individuals struggle to participate. Exercise professionals, including fitness instructors, and personal trainers, are preferred delivery agents for education and instruction on chronic pain, physical activity, and strategies to use adherence-promoting behavioral skills. However, exercise professionals receive no relevant training during certification or continuing education opportunities to effectively support their participants living with chronic pain. Based on the ORBIT model for early pre-efficacy phases of development and testing of new behavioral treatments, the present Phase IIa proof-of-concept study was conducted. The purpose was to examine the impacts of a newly developed chronic pain and physical activity training workshop on psychosocial outcomes among exercise professionals. Outcomes included knowledge and attitudes regarding chronic pain, attitudes and beliefs about the relationship between pain and impairment, and self-efficacy to educate and instruct participants with chronic pain.

METHODS

Forty-eight exercise professionals (M _age=44.4±11.0 years) participated in a three-hour, in-person workshop that was offered at one of four different locations. Participants completed pre- and post-workshop outcome assessment surveys.

RESULTS

Mixed MANOVA results comparing time (pre- versus post-workshop) by workshop location (sites 1 to 4) illustrated a significant within-subjects time effect (p<0.001). All outcomes significantly improved from pre- to post-workshop (p's<0.001), demonstrating large effect sizes (partial eta-squared values ranging from 0.45 to 0.59).

CONCLUSIONS

Findings offer early phase preliminary support for the effectiveness of the chronic pain and physical activity training workshop for exercise professionals. Based on ORBIT model recommendations, findings warrant future phased testing via a pilot randomized clinical trial as well as testing for impacts that trained professionals have on activity adherence among their clients living with chronic pain. Eventual workshop adoption by exercise professional certification organizations would ensure widespread and sustainable access to qualified exercise professionals to help individuals engage in physical activity. By increasing the capacity of available exercise professionals to deliver effective support, active individuals could better manage their chronic pain and live well.

High kinesiophobia and pain catastrophizing in people with articular cartilage defects in the knee and associations with knee function

PURPOSE

The purpose of this study was to evaluate the extent to which individuals with knee articular cartilage defects (ACDs) have kinesiophobia and pain catastrophizing, and how these psychological factors relate to self-reported knee outcomes.

METHODS

Thirty-five individuals seeking surgical consultation for an ACD in the knee confirmed with 3.0T MRI and 18 controls without history of knee injury participated in the study. Kinesiophobia was measured with the Tampa Scale of Kinesiophobia (TSK), and scored using the modified 11-item (TSK-11) methods. Pain catastrophizing was measured with the Pain Catastrophizing Scale (PCS). Data were analyzed using descriptive statistics, independent t-tests, chi-squared tests and Spearman's correlation coefficients, as appropriate (α = 0.05).

RESULTS

Participants with ACDs reported higher TSK-11 scores (median 27 [IQR 25-29]) and higher PCS scores (median 10 [IQR 4-18]) than controls (median TSK-11 16 [IQR 14-17], p < 0.001; median PCS 0 [IQR 0-9], p < 0.001). Within those with knee ACDs, higher TSK-11 scores were associated with worse knee pain, function on activities of daily living, sports/recreation, and knee-related quality of life scores (rho = -0.38 to -0.61). Higher pain catastrophizing was associated with worse function with activities of daily living and knee-related quality of life (rho = -0.37 to -0.40).

CONCLUSIONS

Kinesiophobia and pain catastrophizing in people with knee ACDs were higher than controls. Higher kinesiophobia and pain catastrophizing were associated with worse function and quality of life. Further study of the impact of these psychological factors on outcomes and prognosis in people with knee ACDs is warranted.

"I Could Do It in My Own Time and When I Really Needed It": Perceptions of Online Pain Coping Skills Training For People With Knee Osteoarthritis

OBJECTIVE

To qualitatively explore the perceptions and experiences of people with knee osteoarthritis (OA) who used an online automated pain coping skills training program (PCST).

METHODS

This was a descriptive qualitative study (based on interpretivist methodology) embedded within a randomized controlled trial. Individual semistructured interviews were conducted with 12 people with knee OA who had participated in an 8-week automated online PCST program while also receiving exercise advice and support from a physical therapist via Skype. Interviews in this study focused specifically on the online PCST program, rather than the physical therapy component. Interviews were audiorecorded, transcribed verbatim, and thematically analyzed.

RESULTS

Five themes arose: 1) easy to understand and follow (clearly explained, presented well), 2) better able to cope with pain (controlling pain, helping relax, pacing self, incorporating skills into exercise program), 3) anonymity and flexibility (no judgement by clinician, work at own pace, accessibility), 4) not always relatable or engaging (some techniques not useful, Americanization of the program, annoying character examples, time consuming and slow-paced), and 5) support from clinician desirable (follow-up from a clinician would be beneficial, worked in tandem with physical therapist-prescribed exercise, desire referral to the program by a trusted source).

CONCLUSION

People with knee OA had generally positive experiences using an online PCST program, suggesting that online PCST is a broadly acceptable and accessible way to help people with OA to manage their pain. User engagement may be enhanced by redesigning some aspects of the program and by provision of support from a clinician.

The effects of cognitive behavioural therapy delivered by physical therapists in knee osteoarthritis pain: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Recent evidence suggests that knee osteoarthritis (KOA) chronic pain can result in brain structural and organizational changes. Thus, patients' pain level, emotional status, and perception of their condition might be negatively altered. An approach to reverse such adaptations to chronic pain is cognitive behavioural therapy (CBT). Combining CBT with exercise might enhance therapy outcomes.

OBJECTIVES

To identify the effect of combining exercise and CBT when delivered by a physical therapist in KOA pain.

METHODS

A systematic search in PubMed, Cochrane, and Medline Complete (EBSCO) databases was conducted from their inception to March 2020, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Study risk of bias and quality were assessed through the Risk-of-bias 2 (ROB2) and PEDro scales.

RESULTS

Six primary studies met eligibility criteria. All studies had a low risk of bias and were divided into two sub-groups, in-person interventions and distance interventions. Both groups of studies showed within group participant improvements. In regards of WOMAC pain subscale, our meta-analysis revealed an overall deduction of -1.42 (95% CI: -1.76, -1.09; I² = 58%), -1.62 (95% CI: -1.97, -1.27; I² = 0%) in centre-based intervention, and -1.28 (95% CI: -1.75, -0.81; I² = 73%) in distance delivered intervention.

CONCLUSION

Combining exercise and CBT seems to be an effective method to reduce KOA pain, although it is based on a small number of studies. Further studies are needed to reveal any differences when each intervention is applied separately.

Effectiveness of pain coping skills training on pain, physical function, and psychological outcomes in patients with osteoarthritis: A systemic review and meta-analysis

OBJECTIVE

To investigate the effectiveness of pain coping skills training in pain, function, and psychological outcomes for patients with osteoarthritis, compared to the control group; and to compare the effectiveness of pain coping skills training between the intervention involving and without involving exercise.

DATA SOURCES

PubMed, Embase, the Cochrane Library, PEDro, Clinical Trials, and the WHO Clinical Trials Registry Platform (to 30 September 2020).

REVIEW METHODS

To calculate the results, we used standardized mean difference, and mean difference for the outcomes of continuous variables, risk difference for the risk of adverse events. Heterogeneity was identified with I² test, and publication bias was identified with Egger's test.

RESULTS

A total of 1195 patients with osteoarthritis underwent ten trials were included. The intervention group had significant differences in pain (SMD = -0.18; 95% CI -0.29 to -0.06), function (SMD = -0.19; -0.30 to -0.07), coping attempts (SMD = 0.37; 0.24 to 0.49), pain catastrophizing (SMD = -0.16; -0.29 to -0.02), and self-efficacy (SMD = 0.27; 0.07 to 0.46) than the control group. Between-group differences measured by the McMaster Universities Osteoarthritis Index subscales of pain (MD = -0.62; -1.48 to 0.24) or function (MD = -3.01; -6.26 to 0.24) were not statistically significant and did not reach the minimal clinically important differences that have been established. Subgroup analyses revealed no significant subgroup differences. Besides, no specific intervention-related adverse events were identified.

CONCLUSION

Our results supported the effectiveness and safety of pain coping skills training for managing osteoarthritis in pain, function, and psychological aspects. Besides, exercise could not add benefits when combined with pain coping skills training.
