Rehabilitation Applications Based on Behavioral Therapy for People With Knee Osteoarthritis: Systematic Review

BACKGROUND

The development of digital applications based on behavioral therapies to support patients with knee osteoarthritis (KOA) has attracted increasing attention in the field of rehabilitation. This paper presents a systematic review of research on digital applications based on behavioral therapies for people with KOA.

OBJECTIVE

This review aims to describe the characteristics of relevant digital applications, with a special focus on the current state of behavioral therapies, digital interaction technologies, and user participation in design. The secondary aim is to summarize intervention outcomes and user evaluations of digital applications.

METHODS

A systematic literature search was conducted using the keywords "Knee Osteoarthritis," "Behavior Therapy," and "Digitization" in the following databases (from January 2013 to July 2023): Web of Science, Embase, Science Direct, Ovid, and PubMed. The Mixed Methods Assessment Tool (MMAT) was used to assess the quality of evidence. Two researchers independently screened and extracted the data.

RESULTS

A total of 36 studies met the inclusion criteria and were further analyzed. Behavioral change techniques (BCTs) and cognitive behavioral therapy (CBT) were frequently combined when developing digital applications. The most prevalent areas were goals and planning (n=31) and repetition and substitution (n=27), which were frequently used to develop physical activity (PA) goals and adherence. The most prevalent combination strategy was app/website plus SMS text message/telephone/email (n=12), which has tremendous potential. This area of application design offers notable advantages, primarily manifesting in pain mitigation (n=24), reduction of physical dysfunction (n=21), and augmentation of PA levels (n=12). Additionally, when formulating design strategies, it is imperative to consider the perspectives of stakeholders, especially in response to the identified shortcomings in application design elucidated within the study.

CONCLUSIONS

The results demonstrate that "goals and planning" and "repetition and substitution" are frequently used to develop PA goals and PA behavior adherence. The most prevalent combination strategy was app/website plus SMS text message/telephone/email, which has tremendous potential. Moreover, incorporating several stakeholders in the design and development stages might enhance user experience, considering the distinct variations in their requirements. To improve the efficacy and availability of digital applications, we have several proposals. First, comprehensive care for patients should be ensured by integrating multiple behavioral therapies that encompass various aspects of the rehabilitation process, such as rehabilitation exercises and status monitoring. Second, therapists could benefit from more precise recommendations by incorporating additional intelligent algorithms to analyze patient data. Third, the implementation scope should be expanded from the home environment to a broader social community rehabilitation setting.

Telerehabilitation consultations with a physiotherapist for chronic knee pain versus in-person consultations in Australia: the PEAK non-inferiority randomised controlled trial

BACKGROUND

Telerehabilitation whether perceived as less effective than in-person care for musculoskeletal problems. We aimed to determine if physiotherapy video conferencing consultations were non-inferior to in-person consultations for chronic knee pain.

METHODS

In this non-inferiority randomised controlled trial, we recruited primary care physiotherapists from 27 Australian clinics. Using computer-generated blocks, participants with chronic knee pain consistent with osteoarthritis were randomly assigned (1:1, stratified by physiotherapist and clinic) in-person or telerehabilitation (ie, video conferencing) physiotherapist consultations. Participants and physiotherapists were unmasked to group assignment. Both groups had five consultations over 3 months for strengthening, physical activity, and education. Primary outcomes were knee pain (on a numerical rating scale of 0-10) and physical function (using the Western Ontario and McMaster Universities osteoarthritis index of 0-68) at 3 months after randomisation. Primary analysis was by modified intention-to-treat using all available data. This trial is registered with the Australian and New Zealand Clinical Trials Registry, ACTRN12619001240134.

FINDINGS

Between Dec 10, 2019, and June 17, 2022, 394 adults were enrolled, with 204 allocated to in-person care and 190 to telerehabilitation. 15 primary care physiotherapists were recruited. At 3 months, 383 (97%) participants provided information for primary outcomes and both groups reported improved pain (mean change 2·98, SD 2·23 for in-person care and 3·14, 1·87 for telerehabilitation) and function (10·20, 11·63 and 10·75, 9·62, respectively). Telerehabilitation was non-inferior for pain (mean difference 0·16, 95% CI -0·26 to 0·57) and function (1·65, -0·23 to 3·53). The number of participants reporting adverse events was similar between groups (40 [21%] for in-person care and 35 [19%] for telerehabilitation) and none were serious.

INTERPRETATION

Telerehabilitation with a physiotherapist is non-inferior to in-person care for chronic knee pain.

Home-based vs center-based exercise on patient-reported and performance-based outcomes for knee osteoarthritis: a systematic review with meta-analysis

Background

Home-based exercise (HBE) represents an alternative to increase the accessibility of rehabilitation programs and relieve the burden on the health care system for people with knee osteoarthritis.

Objectives

To summarize for the first time the effectiveness of HBE as compared to center-based exercise (CBE), both with and without HBE, on patient-reported and performance-based outcomes in people with KOA.

Methods

Searches were conducted on PubMed, Cochrane, Embase, Web of Science, and Scopus until March 10, 2023, without date or language restrictions. Randomized controlled trials investigating HBE versus CBE or HBE combined with CBE for people with KOA were eligible. The primary outcomes were patient-reported: pain, physical disability, and quality of life. The secondary outcomes were performance-based: walking ability, lower limb muscle strength, and balance function. Risk of bias was assessed with the Cochrane Risk of Bias tool and quality of evidence according to the GRADE.

Results

Eleven trials involving 956 participants were included. There was no difference in short-term pain (SMD, 0.22 [95% CI, -0.04 to 0.47], p = 0.09; I2 = 0%), physical disability (SMD, 0.17 [95% CI, -0.19 to 0.54], p = 0.35; I2 = 0%), walking ability (SMD, -0.21 [95% CI, -0.64 to 0.22], p = 0.33; I2 = 35%) and lower limb muscle strength (SMD, -0.24 [95% CI, -0.88 to 0.41], p = 0.47; I2 = 69%) between HBE and CBE. HBE combined with CBE has better benefits compared with HBE alone in short-term pain (SMD, 0.89 [95% CI, 0.60 to 1.17], p < 0.001; I2 = 11%) and physical disability (SMD, 0.25 [95% CI, 0.00 to 0.50], p = 0.05; I2 = 0%).

Conclusion

Based on limited evidence, HBE is as effective as CBE on short-term pain, physical disability, walking ability, and lower limb muscle strength in people with knee osteoarthritis. Furthermore, combining HBE with CBE may enhance the overall efficacy of the intervention.

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.

Effect of the telemedicine-supported multicomponent exercise therapy in patients with knee osteoarthritis: study protocol for a randomized controlled trial

INTRODUCTION

The rising prevalence of knee osteoarthritis is placing a considerable strain on the global healthcare system. To address this issue, telemedicine-supported multicomponent exercise therapy has emerged as a promising approach. This therapy combines exercise, patient education, and health coaching to empower knee osteoarthritis patients to manage their condition from the comfort of their homes. Nevertheless, there are some existing limitations in the current research on this approach, including challenges related to patient compliance and the absence of objective evaluation methods.

METHODS AND ANALYSIS

Patients diagnosed with knee osteoarthritis, who have not undergone knee surgery in the past year, will be recruited for a randomized controlled trial. The trial will include an intervention group and a control group. The intervention group will receive an mHealth app-based multicomponent exercise therapy, consisting of exercise therapy, patient education, and health coaching. Meanwhile, the control group will receive usual care, involving drug therapy and patient education. The primary outcome of the trial will be the measurement of pain intensity, assessed using a visual analog scale at baseline and at 4, 8, and 12 weeks of the post-intervention. To analyze the data, a two-factor, four-level repeated measures ANOVA will be used if the assumptions of homogeneity of variance and sphericity are met. If not, a mixed effects model will be employed.

DISCUSSION

The aim of the study is to evaluate the effectiveness of multicomponent exercise therapy aimed at enhancing pain self-management for knee osteoarthritis patients in the comfort of their own homes. The intervention incorporate wearable devices equipped with advanced deep learning systems to monitor patients' adherence to the prescribed at-home exercise regimen, as well as to track changes in outcomes before and after the exercise sessions. The findings from this trial have the potential to enhance both the accessibility and quality of care provided to knee osteoarthritis patients, offering valuable insights for future improvements in their treatment and management.

Face-to-face and telerehabilitation delivery of circuit training have similar benefits and acceptability in patients with knee osteoarthritis: a randomised trial

QUESTION

Is periodised circuit training delivered via a telerehabilitation model of care as effective as the same training applied face-to-face for improving pain intensity, physical function, muscle strength, pain catastrophising, body composition, intermuscular adipose tissue and muscle architecture in people with knee osteoarthritis (OA)?

DESIGN

Randomised controlled, non-inferiority trial with concealed allocation, blinded assessors and intention-to-treat analysis.

PARTICIPANTS

One hundred adults aged ≥ 40 years with knee OA and pain for ≥ 3 months, with current pain ≥ 40 mm on a 100-mm visual analogue scale (VAS).

INTERVENTION

The experimental group received 14 weeks of circuit training delivered via telerehabilitation using video recordings, followed by periodic phone calls in order to motivate and instruct participants. The control group received the same circuit training program in a face-to-face format.

OUTCOME MEASURES

The primary outcomes were pain VAS and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function subscale, measured at 14 weeks. Secondary outcomes included objective physical function, strength, pain catastrophising and morphological measures (muscle architecture and thigh and body composition). Outcomes were measured at 14 and 26 weeks.

RESULTS

Periodised circuit training delivered via telerehabilitation had equivalent effects to face-to-face delivery for pain intensity, physical function, muscle strength, pain catastrophising, thigh composition, intermuscular adipose tissue and muscle architecture. Whole body composition did not change appreciably in either group. Adherence to the training was excellent and participants in each group reported good perceptions of their randomised intervention.

CONCLUSION

A periodised circuit training protocol can be delivered to people with knee OA in their own homes, using available technology while maintaining high levels of acceptability. More importantly, telerehabilitation appears to cause non-inferior physical and functional outcomes to face-to-face rehabilitation programs.

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.

Videoconferencing of Movement-Based and Psychologically Informed Interventions for Chronic Pain: A Systematic Review and Horizon Scan

Introduction: With the coronavirus disease 2019 (COVID-19) pandemic, use of telehealth technology increased dramatically. Nonpharmacological approaches to pain management may be well suited for virtual care. Yet, it is not widely understood if this treatment modality is effective when delivered via videoconferencing. This review examines the effectiveness of movement-based and psychologically informed chronic pain management interventions delivered via videoconferencing compared to in-person care. Methods: Searches of MEDLINE® (via Ovid®), Embase (via Elsevier), CINAHL Complete (via EBSCO), and Cochrane Central Register of Controlled Trials (via Ovid) were performed from inception to June 10, 2021. All articles meeting eligibility criteria were included for data abstraction. Results: Eight thousand two hundred fifty-two citations were identified, and after removing duplicates, 4,661 citations remained. One study investigating acceptance and commitment therapy met eligibility criteria. The noninferiority randomized trial found no statistically significant difference in outcomes between delivery modalities. A horizon scan was conducted to assess planned or recent studies. Horizon scan results yielded six protocols in trial databases, one pilot study, and three published protocols for ongoing studies. Discussion: Findings from this study indicate that virtually delivered pain management is a possible substitute for in-person care. Given the paucity of evidence on this topic, further comparative and adequately powered studies that assess the impact of movement-based and psychologically informed pain management delivered via videoconferencing are needed. Conclusions: Research is needed to understand patient preferences of such interventions within a variety of settings. Such evaluations will be needed to guide clinical and operations practice to optimize equitable deployment and access to high-quality health care delivered via videoconferencing.

Absence of Improvement With Exercise in Some Patients With Knee Osteoarthritis: A Qualitative Study of Responders and Nonresponders

OBJECTIVE

To compare the perceptions of patients about why they did, or did not, respond to a physical therapist-supported exercise and physical activity program.

METHODS

This was a qualitative study within a randomized controlled trial. Twenty-six participants (of 40 invited) with knee osteoarthritis sampled according to response (n = 12 responders, and 14 nonresponders based on changes in both pain and physical function at 3 and 9 months after baseline) to an exercise and physical activity intervention. Semistructured individual interviews were conducted. Inductive thematic analysis was undertaken within each subgroup using grounded theory principles. A deductive approach compared themes and subthemes across subgroups. Findings were triangulated with quantitative data.

RESULTS

(Sub)themes common to responders and nonresponders included the intervention components that facilitated engagement, personal attitudes and expectations, beliefs about osteoarthritis and exercise role, importance of adherence, and perceived strength gains with exercise. In contrast to responders who felt empowered to self-manage, nonresponders accepted responsibility for lack of improvement in pain and function with exercise, acknowledging that their adherence to the intervention was suboptimal (confirmed by quantitative adherence data). Nonresponders believed that their excess body weight (supported by quantitative data) contributed to their outcomes, encountered exercise barriers (comorbidities, stressors, and life events), and perceived that the trial measurement tools did not adequately capture their response to exercise.

CONCLUSION

Responders and nonresponders shared some similar perceptions of exercise. However, along with perceived limitations in trial outcome measurements, nonresponders encountered challenges with excess weight, comorbidities, stressors, and life events that led to suboptimal adherence and collectively were perceived to contribute to nonresponse.

Technical issues occur but are infrequent and have little impact on physiotherapist-delivered videoconferencing consultations for knee osteoarthritis: A descriptive study

INTRODUCTION

Clinicians often report technical issues as a barrier to adopting videoconferencing service models. This descriptive study nested within a randomised controlled trial investigated the frequency, nature and impact of technical issues during video consultations.

METHODS

Physiotherapists (n = 15) underwent training to deliver knee osteoarthritis care focussed on education, strengthening and physical activity. In the randomised controlled trial, participants received five physiotherapy consultations either in-person or via videoconferencing (via Zoom) over 3-months; consultations were recorded and physiotherapists documented technical difficulties. In this study, available notes were audited (n = 169 initial and n = 147 final consultations) and nature and frequency of technical issues coded. Based on whether the clinician reported technical difficulties, three subgroups were created for analysis 1) in-person, 2) videoconferencing without technical issues, 3) videoconferencing with technical issues. Forty participants were randomly selected for each subgroup (n = 120). Duration of consultation components (set-up and introduction, assessment, exercise, physical activity, education and wrap-up), total consultation duration and duration of technical issues were compared across subgroups using one-way multivariate analyses of variance with mean differences (MD) and 95% confidence intervals (CIs).

RESULTS

Technical issues were documented in 37% (initial) and 19% (final) of video consultations. Problems with audio/video were most frequent, occurring in 36-21% (initial) and 18-24% (final) consultations. Audio/video problems were predominantly experienced during set-up, but did not significantly increase videoconferencing consultation duration compared to in-person consultation duration (MD (95% CI) 0.72 (-3.57 to 5.01) minutes).

DISCUSSION

While technical issues with videoconferencing consultations frequently occur, they are typically minor, transient and resolved quickly.

Exercise Therapy for Knee and Hip Osteoarthritis: Is There An Ideal Prescription?

Purpose of review

Exercise therapy is the first line treatment for patients with knee and hip osteoarthritis (OA) but is consistently underutilized. In this review, we aim to provide health care professionals with an overview of the latest evidence in the areas of exercise therapy for OA, which can serve as a guide for incorporating the ideal exercise therapy prescription in the overall management plan for their patients with OA.

Recent findings

Evidence continues to be produced supporting the use of exercise therapy for all patients with knee or hip OA. Ample evidence exists suggesting exercise therapy is a safe form of treatment, for both joint structures and the patient overall. Several systematic reviews show that exercise therapy is likely to improve patient outcomes, regardless of disease severity or comorbidities. However, no single type of exercise therapy is superior to others.

Summary

Health care practitioners and patients should be encouraged to incorporate exercise therapy into treatment plans and can be assured of the safety profile and likelihood of improvement in important patient outcomes. Since no single exercise therapy program shows vastly superior benefit, patient preference and contextual factors should be central to the shared decision-making process when selecting and individualising appropriate exercise therapy prescriptions.

Remotely delivered, individualized, and self-directed gait modification for knee osteoarthritis: A pilot trial

BACKGROUND

Gait modification interventions have reported variable results and relied on in-person biofeedback limiting clinical accessibility. Our objective was to assess a remotely delivered and self-directed gait modification for knee osteoarthritis.

METHODS

This was an unblinded, 2-arm, delayed control, randomized pilot trial (NCT04683913). Adults aged ≥50 years with symptomatic medial knee osteoarthritis were randomized to an immediate group (Week 0: Baseline, Intervention; Week 6: Follow-up, Week 10: Retention) or delayed group (Week 0: Baseline, Wait Period, Week 6: Secondary Baseline, Intervention, Week 12: Follow-up, Week 16: Retention). Participants practiced modifying their foot progression angle "as much as was comfortable" while receiving support via weekly telerehabilitation appointments and remote monitoring with an instrumented shoe. Primary outcomes included participation, foot progression angle modification magnitude, confidence, difficulty, and satisfaction while secondary outcomes included symptoms and knee biomechanics during gait.

RESULTS

We screened 134 people and randomized 20. There was no loss to follow up and 100% attendance at the telerehabilitation appointments. By follow up, participants reported high confidence (8.6/10), low difficulty (2.0/10), and satisfaction (75%) with the intervention and no significant adverse events. Foot progression angle was modified by 11.4° ± 5.6, which was significantly different (p < 0.001, η²_g = 0.8) when compared between groups. No other between-group differences were significant, while several significant pre-post improvements in pain (d = 0.6, p = 0.006) and knee moments (d = 0.6, p = 0.01) were observed.

INTERPRETATION

A personalized, self-directed gait modification supported with telerehabilitation is feasible, and the preliminary effects on symptoms and biomechanics align with past trials. A larger trial is warranted to evaluate efficacy.

Virtual Tools to Enable Management of Knee Osteoarthritis

Purpose of review

There is increasing recognition that virtual tools, enabled by the internet and telecommunications technology, can increase access to health care. We review evidence about the clinical effectiveness and acceptability of telephone-delivered and videoconferencing clinician consultations, websites and internet-delivered programs, and SMS and mobile applications in enabling the management of people with knee osteoarthritis (OA). We discuss barriers to using virtual tools and suggest strategies to facilitate implementation in clinical settings.

Recent findings

An increasing number of systematic reviews, meta-analyses, and clinical trials provide evidence showing the effectiveness of virtual tools for improving knee OA management. Qualitative research shows that virtual tools increase patient access to knee OA care, are generally acceptable and convenient for patients, but can be associated with barriers to use from patient and clinician perspectives.

Summary

Virtual tools offer new opportunities to enable people with knee OA to manage their condition and receive care that may otherwise be difficult or not possible to access. Telephone calls and videoconferencing can be used for real-time synchronous consultations between clinicians and patients, increasing the geographic reach of health services. Websites and internet-based programs can be used to educate patients about their condition, as well as deliver exercise, weight management, and psychological interventions. Mobile apps can monitor and track OA symptoms, exercise, and physical activity, while SMS can facilitate positive behaviour changes for self-management over the long-term when sustained clinician contact may not be possible.

Effect of Information Content and General Practitioner Recommendation to Exercise on Treatment Beliefs and Intentions for Knee Osteoarthritis: An Online Multi-Arm Randomized Controlled Trial

OBJECTIVE

To evaluate effects of general osteoarthritis (OA) information in addition to a treatment option grid and general practitioner (GP) recommendation to exercise on treatment beliefs and intentions.

METHODS

An online randomized trial of 735 people 45 years old or older without OA who were recruited from a consumer survey network. Participants read a hypothetical scenario about visiting their GP for knee problems and were randomized to the following: i) 'general information', ii) 'option grid' (general information plus option grid), or iii) 'option grid plus recommendation' (general information plus option grid plus GP exercise recommendation). The primary outcome was an agreement that exercise is the best management option (0-10 numeric rating scale; higher scores indicating higher agreement that exercise is best). The secondary outcomes were beliefs about other management options and management intentions. Linear regression models estimated the mean (95% confidence interval [CI]) between-group difference in postintervention scores, adjusted for baseline.

RESULTS

Option grid plus recommendation led to higher agreement that exercise is the best management by a mean of 0.4 units (95% CI: 0.1-0.6) compared with general information. There were no other between-group differences for the primary outcome. Option grid led to higher agreement that surgery was best, and x-rays were necessary, compared with general information (mean between-group differences: 0.7 [CI: 0.2-1.1] and 0.5 [CI: 0.1-1.0], respectively) and option grid plus recommendation (0.5 [CI: 0.1-0.9] and 0.9 [CI: 0.4-1.3]).

CONCLUSION

Addition of an option grid and GP exercise recommendation to general OA information led to more favorable views that exercise was best for the hypothetical knee problem. However, differences were small and of unclear clinical importance.

Comparing an Expanded Versus Brief Telehealth Physical Therapy Intervention for Knee Osteoarthritis: Study Protocol for the Delaware PEAK Randomized Controlled Trial

OBJECTIVE

The purpose of this study is to investigate whether a remotely delivered physical therapist intervention increases physical activity (PA) over 12 weeks, compared to existing web-based resources, in adults with knee osteoarthritis (OA).

METHODS

This will be a single-center, randomized controlled trial with 2 parallel arms: (1) the Expanded Intervention (Delaware PEAK [Physical Exercise and Activity for Knee osteoarthritis]), which includes five 45- to 60-minute video conference-based sessions of supervised exercise (strengthening exercises, step goals) that are remotely delivered over 12 weeks by a physical therapist, or (2) the Brief Intervention (control group), a website that includes prerecorded videos directing participants to web-based resources for strengthening, PA, and pain management for knee OA that are freely available online. The trial will enroll 100 participants who meet the National Institute for Health and Care Excellence (NICE) OA clinical criteria (≥45 years old, have activity-related knee pain, have no morning stiffness or it lasts ≤30 minutes), reside in the contiguous US (excluding Alaska and Hawaii), and are seeking to be more physically active. Outcomes include PA (time in moderate-to-vigorous exercise and light exercise, steps/day), sedentary behaviors, treatment beliefs, and self-efficacy for exercise. Our primary outcome is moderate-to-vigorous PA (MVPA). Outcomes will be measured at baseline, 12 weeks, and 24 weeks.

IMPACT

This protocol focuses on the remote delivery of physical therapy via telehealth to adults with knee OA and comes at a critical time, as the burden of inactivity is of particular concern in this population. If successful, the findings of this work will provide strong support for the broad implementation of Delaware PEAK, highlight the utility of telehealth in physical therapy, and address the critical need to utilize exercise to manage adults with knee OA through physical therapists.

Exercise adherence Mobile app for Knee Osteoarthritis: protocol for the MappKO randomised controlled trial

Background

In people with knee osteoarthritis (OA), ongoing exercise participation, particularly with strengthening exercises, is central to management. Patient adherence to prescribed exercise typically declines once consultations with a clinician have ceased. Mobile applications (apps) can incorporate behaviour change techniques that may assist adherence, potentially optimising clinical outcomes.

Methods

This is a two-arm, pragmatic, superiority randomised trial. One hundred and eighty two Australians with chronic knee pain (clinical knee OA) and who have at least a mild level of physical dysfunction are being recruited. Participants are randomly allocated i) exercise (physiotherapist-prescribed exercise) or; ii) exercise plus app (physiotherapist-prescribed exercise plus access to the ‘My Exercise Messages’ mobile app). Exercise care comprises two videoconferencing consultations with a physiotherapist over two weeks (30 min each) for a strengthening exercise program, which is then conducted independently at home for 24 weeks without any further physiotherapist consultations. Participants are also provided with exercise resources to facilitate home-based exercise. Those randomised to exercise plus app will download the app after completing the two weeks of physiotherapy consultations and will be instructed by research staff to use the app for the 24 weeks of unsupervised home-based exercises. The app works by tracking completion of weekly exercise sessions, providing regular messages to facilitate weekly exercise and providing personalised messages to help overcome individual barriers to exercise participation. The two primary outcomes are i) self-reported physical function; and ii) number of days strengthening exercises were performed (previous fortnight), with a primary endpoint of 26 weeks and a secondary endpoint of 14 weeks. Secondary outcomes include knee pain severity; knee-related quality of life; global change; exercise program satisfaction; exercise self-efficacy; physical activity; sport and recreation function; another measure of exercise adherence; and willingness to undergo joint replacement. Process measures are also included.

Discussion

Findings will determine if a theory-informed mobile app improves exercise adherence and physical function in people with knee OA who have received a home-based strengthening program.

Effectiveness of a telehealth physiotherapist-delivered intensive dietary weight loss program combined with exercise in people with knee osteoarthritis and overweight or obesity: study protocol for the POWER randomized controlled trial

BACKGROUND

Obesity is associated with knee osteoarthritis (OA). Weight loss, alongside exercise, is a recommended treatment for individuals with knee OA and overweight/obesity. However, many patients cannot access weight loss specialists such as dietitians. Innovative care models expanding roles of other clinicians may increase access to weight loss support for people with knee OA. Physiotherapists may be well placed to deliver such support. This two-group parallel, superiority randomized controlled trial aims to compare a physiotherapist-delivered diet and exercise program to an exercise program alone, over 6 months. The primary hypothesis is that the physiotherapist-delivered diet plus exercise program will lead to greater weight loss than the exercise program.

METHODS

88 participants with painful knee OA and body mass index (BMI) > 27 kg/m² will be recruited from the community. Following baseline assessment, participants will be randomised to either exercise alone or diet plus exercise groups. Participants in the exercise group will have 6 consultations (20-30 min) via videoconference with a physiotherapist over 6 months for a strengthening exercise program, physical activity plan and educational/exercise resources. Participants in the diet plus exercise group will have 6 consultations (50-75 min) via videoconference with a physiotherapist prescribing a ketogenic very low-calorie diet with meal replacements and educational resources to support weight loss and healthy eating, plus the intervention of the exercise only group. Outcomes are measured at baseline and 6 months. The primary outcome is percentage change in body weight measured by a blinded assessor. Secondary outcomes include self-reported knee pain, physical function, global change in knee problems, quality of life, physical activity levels, and internalised weight stigma, as well as BMI, waist circumference, waist-to-hip ratio, physical performance measures and quadriceps strength, measured by a blinded assessor. Additional measures include adherence, adverse events, fidelity and process measures.

DISCUSSION

This trial will determine whether a physiotherapist-delivered diet plus exercise program is more effective for weight loss than an exercise only program. Findings will inform the development and implementation of innovative health service models addressing weight management and exercise for patients with knee OA and overweight/obesity.

An e-Learning Program for Physiotherapists to Manage Knee Osteoarthritis Via Telehealth During the COVID-19 Pandemic: Real-World Evaluation Study Using Registration and Survey Data

BACKGROUND

The COVID-19 pandemic necessitated clinicians to transition to telehealth, often with little preparation or training. The Physiotherapy Exercise and Physical Activity for Knee Osteoarthritis (PEAK) e-learning modules were developed to upskill physiotherapists in management of knee osteoarthritis (OA) via telehealth and in-person. In the research setting, the e-learning modules are perceived by physiotherapists as effective when they are part of a comprehensive training program for a clinical trial. However, the effectiveness of the modules on their own in a real-world setting is unknown.

OBJECTIVE

This study aims to evaluate the reach, effectiveness, adoption, and implementation of PEAK e-learning modules.

METHODS

This longitudinal study was informed by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Participants were clinicians, researchers, educators, and health care students who registered for access to the modules between April 1 and November 30, 2020. Reach was evaluated by outcomes (countries, referral sources, and attrition) extracted from registration data and embedded within precourse surveys in the Learning Management System (LMS). Effectiveness was evaluated by outcomes (confidence with videoconferencing; likelihood of using education, strengthening exercise, and physical activity in a treatment plan for knee OA; usefulness of modules) measured using a 10-point numeric rating scale (NRS; score range from 1=not confident or likely or useful at all to 10=extremely confident or likely or useful) in pre- and postcourse (on completion) surveys in the LMS. Adoption and implementation were evaluated by demographic and professional characteristics and outcomes related to the use of learning and usefulness of program elements (measured via a 4-point Likert scale, from not at all useful to extremely useful) in a survey administered 4 months after module completion.

RESULTS

Broad reach was achieved, with 6720 people from 97 countries registering for access. Among registrants, there were high levels of attrition, with 36.65% (2463/6720) commencing the program and precourse survey and 19.61% (1318/6720) completing all modules and the postcourse survey. The program was effective. Learners who completed the modules demonstrated increased confidence with videoconferencing (mean change 3.1, 95% CI 3.0-3.3 NRS units) and increased likelihood of using education, strengthening and physical activity in a knee OA treatment plan, compared to precourse. Adoption and implementation of learning (n=149 respondents) occurred at 4 months. More than half of the respondents used their learning to structure in-person consultations with patients (80/142, 56.3%) and patient information booklets in their clinical practice (75/142, 52.8%).

CONCLUSIONS

Findings provide evidence of the reach and effectiveness of an asynchronous self-directed e-learning program in a real-world setting among physiotherapists. The e-learning modules offer clinicians an accessible educational course to learn about best-practice knee OA management, including telehealth delivery via videoconferencing. Attrition across the e-learning program highlights the challenges of keeping learners engaged in self-directed web-based learning.

Perceived Usefulness of Telerehabilitation of Musculoskeletal Disorders: A Belgium-France Pilot Study during Second Wave of COVID-19 Pandemic

BACKGROUND

COVID-19 has affected the practice of physiotherapy, and telerehabilitation (TR) may be seen as an alternative model of care if it is accepted by patients and physiotherapists. This study investigates the perceived usefulness of TR and the intention to use it among physiotherapists and patients from Belgium and France concerned with musculoskeletal disorders (MSDs) during the pandemic period.

METHODS

An online questionnaire based on the technology-acceptance model was designed. Sociodemographic data were collected and Likert scales were proposed to assess perceived ease-of-use, perceived usefulness and intention to use TR. Data were collected between 17 January and 17 March 2021; 68 patients and 107 physiotherapists answered.

RESULTS

In total, 88% of patients and 76% physiotherapists had not used TR at the time they answered. Only 12% of patients and 1% of physiotherapists are willing to use TR, and 50% of physiotherapists think they will never use TR compared to 25% of patients. A total of 98% of participants agreed that they had a good mastery of the technological tools requested.

CONCLUSIONS

Physiotherapists are more reluctant to use TR than patients, regardless of convincing EBM results. This is related to their own representation of proper MSD management, which must include the use of hands-on techniques.

Evaluation of a Novel e-Learning Program for Physiotherapists to Manage Knee Osteoarthritis via Telehealth: Qualitative Study Nested in the PEAK (Physiotherapy Exercise and Physical Activity for Knee Osteoarthritis) Randomized Controlled Trial

BACKGROUND

The delivery of physiotherapy via telehealth could provide more equitable access to services for patients. Videoconference-based telehealth has been shown to be an effective and acceptable mode of service delivery for exercise-based interventions for chronic knee pain; however, specific training in telehealth is required for physiotherapists to effectively and consistently deliver care using telehealth. The development and evaluation of training programs to upskill health care professionals in the management of osteoarthritis (OA) has also been identified as an important priority to improve OA care delivery.

OBJECTIVE

This study aims to explore physiotherapists' experiences with and perceptions of an e-learning program about best practice knee OA management (focused on a structured program of education, exercise, and physical activity) that includes telehealth delivery via videoconferencing.

METHODS

We conducted a qualitative study using individual semistructured telephone interviews, nested within the Physiotherapy Exercise and Physical Activity for Knee Osteoarthritis randomized controlled trial, referred to as the PEAK trial. A total of 15 Australian physiotherapists from metropolitan and regional private practices were interviewed following the completion of an e-learning program. The PEAK trial e-learning program involved self-directed learning modules, a mock video consultation with a researcher (simulated patient), and 4 audited practice video consultations with pilot patients with chronic knee pain. Interviews were audio recorded and transcribed verbatim. Data were thematically analyzed.

RESULTS

A total of five themes (with associated subthemes) were identified: the experience of self-directed e-learning (physiotherapists were more familiar with in-person learning; however, they valued the comprehensive, self-paced web-based modules. Unwieldy technological features could be frustrating); practice makes perfect (physiotherapists benefited from the mock consultation with the researcher and practice sessions with pilot patients alongside individualized performance feedback, resulting in confidence and preparedness to implement new skills); the telehealth journey (although inexperienced with telehealth before training, physiotherapists were confident and able to deliver remote care following training; however, they still experienced some technological challenges); the whole package (the combination of self-directed learning modules, mock consultation, and practice consultations with pilot patients was felt to be an effective learning approach, and patient information booklets supported the training package); and impact on broader clinical practice (training consolidated and refined existing OA management skills and enabled a switch to telehealth when the COVID-19 pandemic affected in-person clinical care).

CONCLUSIONS

Findings provide evidence for the perceived effectiveness and acceptability of an e-learning program to train physiotherapists (in the context of a clinical trial) on best practice knee OA management, including telehealth delivery via videoconferencing. The implementation of e-learning programs to upskill physiotherapists in telehealth appears to be warranted, given the increasing adoption of telehealth service models for the delivery of clinical care.

Management of knee and hip osteoarthritis: an opportunity for the Canadian chiropractic profession

Knee and hip osteoarthritis (OA) place a significant burden on the Canadian health system and are a major public health challenge. This brief commentary discusses the recently published Osteoarthritis Research Society International guideline and the American College of Rheumatology guideline for the management of OA. Special attention has been given to the role of manual therapy, exercise, and patient education for the treatment of knee and hip OA. This article also reviews the Good Life with osteoArthritis in Denmark (GLA:D®) treatment program for knee and hip OA and the implementation of this program in Canada. Lastly, the authors discuss the opportunity for the Canadian chiropractic profession to embrace treatment programs like GLA:D® and take an active role in the strengthening of the Canadian health system from a musculoskeletal perspective.
