Are the Effects of Resistance Exercise on Pain and Function in Knee and Hip Osteoarthritis Dependent on Exercise Volume, Duration, and Adherence? A Systematic Review and Meta-Analysis

Abstract

Objective: The purpose of this study was to determine dose parameters for resistance exercise associated with improvements in pain and physical function in knee and hip osteoarthritis (OA) and whether these improvements were related to adherence. Methods: We searched six databases, from inception to January 28, 2023, for randomized controlled trials comparing land-based, resistance exercise–only interventions with no intervention, or any other intervention. There were four subgroups of intervention duration: 0 to 6 to 6 to 6 to <12 months) duration improve pain and physical function. Improvements do not depend on exercise volume or adherence, suggesting exercise does not require rigid adhere..
