Abstract

OBJECTIVE: To evaluate, in a community hip osteoarthritis sample, the cross-sectional associations of isometric strength and steadiness of the knee extensors and their interaction with physical performance measures of physical function. DESIGN: Cross-sectional. SETTING: Human movement laboratory of a university. PARTICIPANTS: Sixty-seven adults (27 men and 40 women; age, 61+/-10 y) with radiographically confirmed symptomatic hip osteoarthritis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants performed isometric knee extensor steadiness and strength testing on a dynamometer. Physical function was assessed by using the habitual timed walk test and the self- and fast-paced st..
