LORAINE DEVOS-COMBY, TERRY CRONAN, and SCOTT C. ROESCH ABSTRACT. Methods. A metaanalysis was conducted on 16 studies reporting exercise and/or self-management interventions for patients with knee OA. The effects on physical and psychological well-being were assessed immediately after the interventions. Results. Compared to control conditions, exercise regimens led to improvement in physical health (by self-report and direct measures) and in overall impact of OA. Perceived psychological health remained unchanged by the exercise programs. Although the effect sizes for the self-management programs were significant for psychological outcomes and for the overall effect of OA, there was a significant difference between self-management and control groups only in psychological outcomes. Conclusion. Overall, both patient education and exercise regimens had a modest, yet clinically important, influence on patients' well-being. (J Rheumatol 2006;33:744–56)
