Effects of Chair-Based Exercises on Perceived Therapeutic and Quality of Life in Inactive Older Adults With Knee Osteoarthritis: A Randomized Controlled Trial.

研究概要

41 physically inactive adults aged 65 years or older with knee osteoarthritis (OA) were randomized to an 8-week supervised chair-based exercise program or to continue their usual activities. The primary outcome used for the sample size calculation was pain on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Other outcomes included WOMAC stiffness and physical function, mobility and dynamic balance on the Timed Up and Go (TUG) test, perceived exercise benefits and barriers, and health-related quality of life. Outcomes were assessed at baseline and after the program. Overall, chair-based exercise improved pain, stiffness, physical function, mobility, and quality of life compared with usual activities. Participants also reported more benefits and fewer barriers to exercise, suggesting that chair-based training could offer an accessible way for inactive older adults with knee OA to begin exercising.
