Physical Function in Hip Osteoarthritis: Relationship to Isometric Knee Extensor Steadiness

Abstract

Pua Y-H, Clark RA, Bryant AL. Physical function in hip osteoarthritis: relationship to isometric knee extensor steadiness. 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±10y) with radiographically confirmed symptomatic hip osteoarthritis. Interventions: Not applicable. Main Outcome Measures: Participants performed isometric knee extensor steadiness and strength testin..
