Résumé : |
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 walk time, and repeated chair stand time over 36 months. Results Compared with the slowest tertile of RFD, the fastest tertile had a lower risk for worsening of WOMAC physical function subscale score at 36-month follow-up, with an odds ratio (OR) of .68 (95% confidence interval [CI], .51.92) after adjustment for age, sex, body mass index, depression, history of chronic diseases, and knee pain. In women, in comparison with the slowest tertile of RFD, the fastest tertile had a lower risk for worsening of WOMAC physical function subscale score at 36-month follow-up, with an adjusted OR of .57 (95% CI, .38.86). This decreased risk did not reach statistical significance in men (OR, 0.81; 95% CI, 0.521.27). No statistically significant associations were detected between baseline RFD and walk or chair stand times. Conclusions Our results indicate that higher RFD is associated with decreased risk for worsening self-reported physical function but not with decreased risk for worsening of physical performance. |
