BioMotion Lab


Dr. Zandiyeh, Ph.D., directs the UT Health Biomotion Laboratories in the Department of Orthopedic Surgery. The Biomotion Laboratory conducts extensive preclinical and clinical research focusing on comprehensive biomechanical and electrophysiological measurements in-vivo. Studies utilize advanced 3D imaging (CT and MRI), dynamic assessment of joint function (Using a high-speed Dynamic Stereo X-ray (DSX) system), muscle activities (electromyography), and musculoskeletal modeling. The Biomotion Lab is focused on the following main topics: (1) To investigate how bone and joint injuries and their pathologies impact their dynamic movements during muscle-driven functional activities. (2) To improve diagnosis, treatment, and patient care for patients with orthopedic pathologies.
