Lower Quadriceps Rate of Force Development Is Associated With Worsening Physical Function in Adults With or at Risk for Knee Osteoarthritis: 36-Month Follow-Up Data From the Osteoarthritis Initiative.

ABSTRACT: OBJECTIVE:To determine the association between quadriceps rate of force development (RFD) and decline in self-reported physical function and objective measures of physical performance. DESIGN:Longitudinal cohort study. SETTING:Community-based sample from 4 urban areas. PARTICIPANTS:Osteoarthritis Initiative participants with or at risk for knee osteoarthritis, who had no history of knee/hip replacement, knee injury, or rheumatoid arthritis (N=2630). INTERVENTIONS:Not applicable. MAIN OUTCOME MEASURES:Quadriceps RFD (N/s) was measured during isometric strength testing. Worsening physical function was defined as the minimal clinically important difference for worsening self-reported Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function subscale score, 20-m
