Purpose The purpose of this study was to examine the influence of the exercise program for Osteoarthritis of the knee (knee OA) which American Geriatrics Society Panel on Exercise and Osteoarthritis (AGS) recommends on physical function in Japanese independent elderly with knee joint pain. Methods Subjects of this study were 36 (7 males: aged 74.7±5.1 years, 29 females: aged 72.3±4.6 years) community-dwelling independent elderly with knee joint pain who voluntary participated in our exercise program. The program consisted of massage around knee, flexibility exercises in knee and ankle joints, and leg muscle development exercises. They performed these exercises twelve times for a month at regular intervals. Physical function were evaluated by the muscle strength during knee extension and flexion, the range of motion of knee joint and the center of pressure during upright standing. There were three times measurements at one month before starting of the program (the 1st), immediately before beginning of the program (the 2nd), and just after ending of the program (the 3rd). Difference between change in measurement values during the observation period (subtract the 1st from the 2nd; Δ1) and that during intervention period (subtract the 2nd from the 3rd; Δ2) were analyzed by Students't-test. Results and Conclusion There was significant difference between Δ1 (0.01±0.05kg/wt) and Δ2 (0.04±0.05kg/wt) on maximal muscle strength during knee extension. This result suggested that the exercise program recommended by AGS was improved the leg muscle strength in Japanese elderly with knee joint pain. However the effects of the exercise intervention were not clarified on the other physical function. As for the reasons it seems to affect the initial level of joint pain and physical function in the subjects. Therefore, reexamination of this point with a greater number of samples which the worse level of knee joint pain is needed in the future.
