Furthermore, the role of preoperative muscle function on functional outcome of THA and TKA is poorly understood. A correlation between compromised preoperative muscular function and postoperative outcome would suggest that preoperative physical therapy may be critical for preserving the muscular status and may help explain reported poorer outcome after late treatment when muscular function has already deteriorated. Answers to these questions are highly relevant for developing and improving preoperative treatment schemes and postoperative rehabilitation programs. In particular, understanding the role of strength deficits of specific muscles on dynamic and postural stability will be critical for defining optimal rehabilitation scheme, specifically targeting the muscles responsible for the balance ability and ultimately reducing the risk of falls. The project includes two studies differing in design and primary and secondary objectives but with overlapping patient populations. Gangbild nach Knie- bzw. Hüft-TE Research Project | 5 Project MembersIn this study, we will first identify objective parameters describing gait asymmetry that can be used as outcome measures for future clinical trials. We propose that gait asymmetry can be assessed using a body-worn inertial sensor system (RehaGait®), and that these parameters differ between pre- to postoperative measurements in patients undergoing total arthroplasty and between patients with endstage knee or hip osteoarthritis (OA) and healthy subjects. In a second step we will show that joint biomechanics in the lower extremity of the affected and the contralateral side is influenced by OA and arthroplasty and that gait asymmetry is explained by muscle strength, muscle activity, joint moments and/or passive range of motion. We will include persons with endstage knee (n=50) or hip (n=50) OA and age matched healthy persons (n=50). Gait asymmetry assessed using a portable gait analysis will be compared to that assessed using established laboratory systems and compared between different patient groups and between patients and healthy subjects. Muscle strength, muscle activity, joint moments and range of motion will be tested and related to gait asymmetry. Potential confounders pain and health and functional status will be assessed. 1 1 OverviewMembersPublicationsProjects & Collaborations
