Range of Motion, Muscular Strength and Functionality of Patients Submitted to Total Hip Arthroplasty.

Subjects in the late postoperative phase (5-8 months) of THA and control subjects without any signs or symptoms in the hip joint will be assessed for functionality (Harris Hip Score questionnaire and Timed Up and Go test), level of pain (visual analogue pain scale), hip range of motion and muscle isometric peak torque. This evaluation will be performed in order to compare functionality, level of pain, hip range of motion and peak torque between patients following total hip arthroplasty (THA) and asymptomatic controls.
