Delaware Physical Exercise and Activity for Knee Osteoarthritis — PEAK  

Knee Osteoarthritis Clinical Trial

Official title: Delaware Physical Exercise and Activity for Knee Osteoarthritis (PEAK)

Status Completed

Clinical Trial Summary

The objective of this project is to examine the efficacy of an innovative Telehealth Physical Therapy (PT) program for adults with knee osteoarthritis (OA) to increase physical activity over 12 weeks in adults with knee OA compared to a control group receiving web-based resources about knee OA. One hundred individuals with knee osteoarthritis (OA), who are over the age of 45, and are also looking to move more, will be randomized into a brief or expanded intervention group. The brief intervention includes an online, guided video orientation from a physical therapist to web resources for strengthening exercises, physical activity, and pain management strategies for knee OA. The expanded program includes up to 5 online consultations with a physical therapist over a 12-week period who will prescribe strengthening exercises, physical activity goals, and pain management strategies for knee OA.

Clinical Trial Description

Delaware PEAK (Physical therapy Exercise and Activity for Knee osteoarthritis) is a delivered remotely by a physical therapist over 5 one-on-one video conference (Zoom Platform) consultations lasting 45 to 60 minutes each over 12 weeks. Each consultation focuses on strengthening exercises, physical activity goals, and education to debunk common OA-related myths and misconceptions. Delaware PEAK utilizes a well-established behavioral counseling method, Motivational Interviewing, to increase self-efficacy (confidence) related to exercise, while delivering all aspects of the intervention. The objective of this project is to examine the efficacy of Delaware PEAK to increase physical activity in adults with knee OA compared to a control group receiving web-based resources about knee OA and exercise. The rationale for our study is that there is a need to examine whether PEAK can directly target the mismatch between OA recommendations and practice patterns. Our central hypothesis is that Delaware PEAK will increase physical activity and will increase the belief that exercise is helpful and not harmful, compared with a control group receiving web-based OA treatment resources. Successful completion of this proposal will provide the evidence necessary to scale up this low-cost intervention, with the goal of increasing the number of adults who use exercise to manage their knee OA and thus reducing the burden of disease. The primary endpoint of our study is to examine the efficacy of a physical therapist-delivered exercise intervention (Delaware PEAK) to increase MVPA over 12 weeks compared to a control group receiving web-based resources about knee OA and exercise. The secondary analyses endpoint of our study is to examine the efficacy of a physical therapist-delivered exercise intervention (Delaware PEAK) to increase health beliefs in Physical Exercise and Physical Therapy, light physical activity (LPA), and steps per day, over 24 weeks compared to a control group receiving web-based resources about knee OA and exercise. We also will assess change in MVPA over 24 weeks. Our exploratory endpoints include change in pain, symptoms, function in activities of daily living, function in sport and recreation, and quality of life over 12 weeks and 24 weeks. We will also examine change in treatment expectations before and after randomization. Lastly, we will examine change in treatment adherence from 12 to 24 weeks among those in the expanded intervention group. ;
