University of Oregon

Li-Shan Chou, Ph.D., is currently a Full Professor and Department Head in the Department of Human Physiology at the University of Oregon. Born in Taiwan, Dr. Chou received his BS degree from Tatung Institute of Technology in Taipei. Subsequently, he finished his MS and Ph.D. degrees, both in Mechanical Engineering, from University of Illinois at Chicago in 1991 and 1995, respectively. He then pursued post-doctoral trainings in areas of orthopedic biomechanics and rehabilitation research in University of Chicago and Mayo Clinic. In 2000, he joined the University of Oregon as a faculty member and established the Motion Analysis Laboratory. His research falls under general areas related to biomechanics and motor control of human movement, with focuses on the investigation of mobility impairments associated with ageing, musculoskeletal diseases or injuries, and traumatic brain injury. Dr. Chou’s research has been funded by many federal agencies, including National Institutes of Health, Centers for Disease Control and Prevention, Department of Veterans Affairs, and Department of Defense as well as medical research foundations.

Biomechanical Analysis of Gait Imbalance in the Elderly: Bridging Clinical Assessment with Laboratory Science

Falls among the elderly population are prevalent, dangerous, and costly.  Early fall risk detection and the ability to design targeted interventions are the best remedies for preventing fall injuries in community-dwelling elderly. Therefore, accurate assessment of individual-specific mobility impairment is critical to reducing the incidence of falls and developing treatment interventions. Toward to this front, movement analysis plays a contributing role in the enhancement of our ability to achieve thse goals. During gait, our body is maintained in a continuous state of controlled imbalance, with each subsequent foot strike preventing a fall. With balance impairment, the ability to place the foot properly in order to capture the center of mass and regulate the body’s velocity might be compromised. The purpose of this presentation is to familiarize attendees with biomechanical assessment and quantification of gait imbalance and discuss clinical implications of different biomechanical measures which address the various aspects of gait stability.
