OBJECTIVE. This study assessed the feasibility and preliminary efficacy of an online-assisted, occupational therapist–delivered, cognitive–behavioral therapy intervention to promote physical function in patients with knee osteoarthritis (KOA).

METHOD. Fifty-seven participants with KOA were randomized 2:1 to the Engage program (eight clinic-based sessions supported by online modules) or usual care. Using analysis of covariance, we estimated Engage’s effect on physical function (Western Ontario and McMaster Universities Osteoarthritis Index’s Physical Function subscale [WOMAC–PF]) at 6 mo.

RESULTS. Data were analyzed on 46 completers. Engage was associated with a small effect (η2 = 0.01) on the WOMAC–PF. More Engage participants than controls reported much or very much improvement (45% vs. 13%; p = .03). Satisfaction was high, and 30 of 31 participants attended six sessions or more.

CONCLUSION. An online-supported cognitive–behavioral program for people with KOA delivered by occupational therapists is feasible and may contribute to improved physical function.
