HumanInsight Comparing an Expanded Versus Brief Telehealth Physical Therapy Intervention for Knee Osteoarthritis: Study Protocol for the Delaware PEAK Randomized Controlled Trial
Phys Ther. 2022 Oct 6:pzac139. doi: 10.1093/ptj/pzac139. Online ahead of print.
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.
