Abstract

OBJECTIVES: To identify levels of knee extensor strength that are associated with high and low risk of incident severe mobility limitation (SML) in initially well-functioning older adults. DESIGN: Prospective cohort study. SETTING: University clinic center. PARTICIPANTS: One thousand three hundred fifty-five men and 1,429 women (aged 73.6±2.85) who reported no mobility limitation. MEASUREMENTS: Unilateral knee extensor isokinetic strength of participants was obtained. Participants were followed over a median of 5.90 years for the onset of SML, defined as two consecutive reports of a lot of difficulty or inability to walk one-quarter of a mile or climb 10 steps. Deciles of knee extension strength relative to body weight were evaluated to identify cutpoints most predictive of incident SML. Cutpoints were then compared with prevalence of having slow gait speed (
