Long-Term Adherence and Effectiveness of a Multicomponent Intervention for Community-Dwelling Overweight Thai Older Adults with Knee Osteoarthritis: 1-Year Follow Up

: Being overweight is a major risk factor for developing knee osteoarthritis (OA). The purpose of the current study was to: (a) determine participant adherence to a quadriceps exercise and weight management program after completion of the intervention; and (b) examine whether a quadriceps exercise and weight management program can reduce knee pain and improve knee function and weight loss in 40 community-dwelling overweight Thai older adults with knee OA at 6- and 12-month follow up. Twenty-nine (76.3%) participants completed at least 75% of the program. Two (5%) participants did not complete the program. In the intervention group, significant improvement was noted in knee range of motion at 6 and 12 months compared with baseline, and a significant reduction was noted in knee pain, time spent in the Timed Up and Go test, and body weight compared with baseline. These study variables, except for body weight, between the intervention group and control group were significantly different. This study highlights the benefit of long-term adherence to the multicomponent intervention for community-dwelling overweight Thai older adults with knee OA.
