The Effects of Healthy Lifestyle Management Training and Personalized Physical Activity Counseling: A Randomized Controlled Trial

Knee osteoarthritis is a common condition that causes knee pain, stiffness, and difficulty in daily activities. Physical activity and exercise are recommended as part of the treatment; however, many individuals have difficulty maintaining regular exercise over time. The purpose of this study is to evaluate the effects of different physical activity intervention approaches on pain, physical function, and exercise adherence in individuals with knee osteoarthritis. Participants will be randomly assigned to one of three groups. One group will receive a physiotherapist-supervised exercise and physical activity program. The second group will follow an individualized home-based physical activity program that they will perform independently after receiving initial instruction. The third group will receive usual care and will serve as the control group. The intervention period will last six weeks. Participants in the intervention groups will then be followed for an additional six weeks using telephone-based follow-up to monitor adherence and ongoing physical activity. Outcomes related to pain, physical function, physical activity, and adherence to exercise will be assessed at different time points during the study. The results of this study are expected to improve understanding of how supervised and home-based physical activity programs may contribute to the management of knee osteoarthritis and support the development of effective rehabilitation strategies.
