Behavioural graded activity results in better exercise adherence and more physical activity than usual care in people with osteoarthritis: a cluster-randomised trial.

Question: Does behavioural graded activity result in better exercise adherence and more physical activity than usual care in people with osteoarthritis of the hip or knee? Design: Analysis of secondary outcomes of a cluster-randomised trial with concealed allocation, assessor blinding, and intention-to-treat analysis. Participants: Two hundred patients with hip and/or knee osteoarthritis. Intervention: Experimental group received 18 sessions of behavioural graded activity over 12 weeks and up to 7 booster sessions over the next year. The control group received 18 sessions of usual care over 12 weeks according to the Dutch physiotherapy guideline. Outcome measures: Exercise adherence was measured using a questionnaire and physical activity was measured using the SQUASH questionnaire at baseline, 13, and 65 weeks. Results: Adherence to recommended exercises was significantly higher in the experimental group than in the control group at 13 weeks and at 65 weeks. Significantly more of the experimental than the control group met the recommendations for physical activity at 13 weeks and at 65 weeks.

Behavioural graded activity results in better exercise adherence and more physical activity than usual care in people with osteoarthritis of the hip or knee, both in the short- and long-term.
