Abstract

Objective. To determine the effectiveness of a behavioral graded activity program (BGA) compared with usual care (UC; exercise therapy and advice) according to the Dutch guidelines for physiotherapy in patients with osteoarthritis (OA) of the hip and/or knee. The BGA intervention is intended to increase activity in the long term and consists of an exercise program with booster sessions, using operant treatment principles. Methods. We conducted a cluster randomized trial involving 200 patients with hip and/or knee OA. Primary outcome measures were pain (visual analog scale [VAS] and Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), physical function (WOMAC), and patient global assessment, assessed at weeks 0,13, 39, and 65. Secondary outcome measures comprised tiredness (VAS), patient-oriented physical function (McMaster Toronto Arthritis Patient Preference Disability Questionnaire [MACTAR]), 5-meter walking time, muscle strength, and range of motion. Data were analyzed according to intent-to-treat principle. Results. Both treatments showed short-term and long-term beneficial within-group effects. The mean differences between the 2 groups for pain and functional status were not statistically significant. Significant differences in favor of BGA were found for the MACTAR functional scale and 5-meter walking test at week 65. Conclusion. Because both interventions resulted in beneficial long-term effects, the superiority of BGA over UC has not been demonstrated. Therefore, BGA seems to be an acceptable method to treat patients with hip and/or knee OA, with equivalent results compared with UC.
