About

Introduction: Femoral and acetabular replacement is characterized as total hip arthroplasty (THA). It has been used as treatment of various pathologies of this joint. In the postoperative period, some studies have shown that strength, function, range of motion and lower limb mechanics remains altered for more than One year after THA in relation to the non-operated side. However, studies that have correlated kinematics and hip muscle strength in individuals who underwent THA for long time, do not exist in literature. Objective: to evaluate lower limb muscle strength and 2D kinematics during stair ascending and descending in patients undergoing total hip arthroplasty. Methods: Third individuals who underwent total hip arthroplasty (THA) will be recruited at two, five and 10 year postoperative periods. They were allocated in three groups: Group 1 (10n), subjects submitted to THA for two years, Group 2 (10n) subjects submitted to THA for five years, Group 3 (10n) subjects submitted to THA for 10 years and Group 4 (10n) subjects without orthopaedic afections, all will be evaluated for dynamometric isometric muscle strength and kinematic analysis of stair ascending and descending by a "blinded" physical Therapist.
