The smallest worthwhile effects of strengthening exercise on pain intensity for people with knee osteoarthritis: A benefit-harm trade-off study

Abstract

Objective: To determine the smallest worthwhile effects (SWEs) of supervised individual, supervised group, or unsupervised digitally-delivered strength exercise on pain intensity, compared to no exercise, for individuals with knee osteoarthritis. Method: Online benefit-harm trade-off study. Participants with knee pain consistent with knee osteoarthritis were allocated information about either supervised individual, supervised group, or unsupervised digitally-delivered strength exercise and a no exercise comparison. Participants selected the pain reduction (percentage) that would make their allocated mode of strength exercise worthwhile, in addition to a 15% improvement with no exercise, cons..
