Effects of a 12-Week Multifaceted Wearable-Based Program for People With Knee Osteoarthritis: Randomized Controlled Trial.

BACKGROUND: Current guidelines emphasize an active lifestyle in the management of knee osteoarthritis (OA), but up to 90% of patients with OA are inactive. In a previous study, we demonstrated that an 8-week physiotherapist (PT)-led counseling intervention, with the use of a Fitbit, improved step count and quality of life in patients with knee OA, compared with a control. OBJECTIVE: This study aimed to examine the effect of a 12-week, multifaceted wearable-based program on physical activity and patient outcomes in patients with knee OA. METHODS: This was a randomized controlled trial with a delay-control design. The immediate group (IG) received group education, a Fitbit, access to FitViz (a Fitbit-compatible app), and 4 biweekly phone calls from a PT over 8 weeks. Participants then continued using Fitbit and FitViz independently up to week 12. The delay group (DG) received a monthly electronic newsletter in weeks 1 to 12 and started the same intervention in week 14. Participants were assessed in weeks 13, 26, and 39. The primary outcome was time spent in daily moderate-to-vigorous physical activity (MVPA; in bouts ≥10 min) measured with a SenseWear Mini. Secondary outcomes included daily steps, time spent in purposeful activity and sedentary behavior, Knee Injury and OA Outcome Score, Patient Health Questionnaire-9, Partners in Health Scale, Theory of Planned Behavior Questionnaire, and Self-Reported Habit Index. RESULTS: We enrolled 51 participants (IG: n=26 and DG: n=25). Compared with the IG, the DG accumulated significantly more MVPA time at baseline. The adjusted mean difference in MVPA was 13.1 min per day (95% CI 1.6 to 24.5). A significant effect was also found in the adjusted mean difference in perceived sitting habit at work (0.7; 95% CI 0.2 to 1.2) and during leisure activities (0.7; 95% CI 0.2 to 1.2). No significant effect was found in the remaining secondary outcomes. CONCLUSIONS: A 12-week multifaceted program with the use of a wearable device, an app, and PT counseling improved physical activity in people with knee OA.

Efficacy of a Physical Activity Counseling Program With Use of a Wearable Tracker in People With Inflammatory Arthritis: A Randomized Controlled Trial.

OBJECTIVE: To assess the efficacy of a multifaceted counseling intervention at improving physical activity participation and patient outcomes. METHODS: We recruited people with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). In weeks 1-8, the immediate group received education and counseling by a physical therapist, used a Fitbit and a web application to obtain feedback about their physical activity, and received 4 follow-up calls from the physical therapist. The delay group received the same intervention in weeks 10-17. Participants were assessed at baseline and at weeks 9, 18, and 27. The primary outcome was time spent in moderate/vigorous physical activity (MVPA; in bouts of ≥10 minutes) measured with a SenseWear device. Secondary outcomes included step count, time in sedentary behavior, pain, fatigue, mood, self-management capacity, and habitual behaviors. RESULTS: A total of 118 participants enrolled. The adjusted mean difference in MVPA was 9.4 minutes/day (95% confidence interval [95% CI] -0.5, 19.3, P = 0.06). A significant effect was found in pain (-2.45 [95% CI -4.78, -0.13], P = 0.04), and perceived walking habit (0.54 [95% CI 0.08, 0.99], P = 0.02). The remaining secondary outcomes improved, but were not statistically significant. Post hoc analysis revealed a significant effect in MVPA (14.3 minutes/day [95% CI 2.3, 26.3]) and pain (-4.05 [95% CI -6.73, -1.36]) in participants with RA, but not in those with SLE. CONCLUSION: Counseling by a physical therapist has the potential to improve physical activity in people with inflammatory arthritis, but further study is needed to understand the intervention effect on different diseases. We found a significant improvement in pain, suggesting that the intervention might have a positive effect on symptom management.

Effectiveness of an online self-management tool, OPERAS (an On-demand Program to EmpoweR Active Self-management), for people with rheumatoid arthritis: a research protocol.

BACKGROUND: Active self-management is a process where patients are fully engaged in managing their health in daily life by having access to contextualized health data and tailored guidance to support a healthy lifestyle. This study aims to determine whether an e-health intervention that incorporates symptom/disease activity monitoring and physical activity counselling can improve self-management ability in patients with rheumatoid arthritis (RA). METHODS: The 'Empowering active self-management of arthritis: Raising the bar with OPERAS (an On-demand Program to EmpoweR Active Self-management)' project is a randomized controlled trial that uses a delayed control design. One hundred thirty-four participants with RA will be randomly assigned to start the intervention either immediately (immediate group) or 6 months later (delayed group). The intervention involves (1) use of a Fitbit-compatible web app to record and monitor their RA disease activity, symptoms, and time spent on physical activity and a Fitbit; (2) group education and individual counselling by a physiotherapist (PT); and (3) six phone calls with a PT. The primary outcome measure is self-management ability measured by the Patient Activation Measure. Secondary outcome measures include disease status, fatigue, pain, depressive symptoms, and characteristics of habitual behavior and also time spent in physical activity and sedentary activity with a wearable multi-sensor device (SenseWear Mini). After the 6-month intervention, we will interview a sample of participants to examine their experiences with the intervention. DISCUSSION: The results of this study will help to determine whether this technology-enhanced self-management intervention improves self-management ability and health outcomes for people living with RA. A limitation of this study is that participants will need to self-report their symptoms, disease status, and treatment use through questionnaires on the OPERAS web app. The user-friendly interface, reminder emails from the research staff, and tailored guidance from PTs will encourage participants to actively engage with the app. TRIAL REGISTRATION: Date of last update in ClinicalTrials.gov: January 2, 2019.
