Musculoskeletal injuries due to sports, recreation and exercise (SRE) have reached epidemicproportions as our society attempts to develop a healthier lifestyle. Participation in these activities requires maintenance of lower extremity joint health, yet such involvement presents an inherent risk of developing exercise-induced or traumatic musculoskeletal injuries. Acute injuries to the ankle are among the most frequent musculoskeletal injuries in all levels of SRE. As opposed to the most common lateral ankle sprains (LAS), high ankle sprains (HAS) are more problematic due to their potential for a significantly greater time lost and subsequent chronic ankle dysfunction. While excessive foot inversion and external rotation are suspected in LAS and HAS, respectively, the mechanisms of injury remain unclear. Surprisingly, to date, few studies investigate direct causing factors of ankle sprains. Previous experiments have largely been designed to measure ankle kinematics and joint moments. However, these studies fail to address in vivo ankle ligament strains accompanying excessive foot motions or moments.
This talk will demonstrate a novel methodology that uses kinematic data from video and motion analyses of injury-producing events todrive computational models for estimations of ankle ligament strains and joint moments. Additionally, the talk will also present a potential use of weightbearing, upright MRI to investigate kinematics of the ankle and subtalar joints. The development of new prophylactic measures and targeted rehabilitation therapies will hinge on an accurate understanding of the injury mechanisms and knowledge of the injury-causing factors. These techniques have the potential to provide a better comprehension of LAS and HAS that may help reduce incidence and accelerate recovery for these injuries.
Dr. Wei is currently a Postdoctoral Fellow in the Human Performance and Engineering Laboratory at the Kessler Foundation Research Center in West Orange, New Jersey. He received his PhD in Mechanical Engineering from Michigan State University, supervised by Dr. Roger Haut. His research interests include human musculoskeletal system modeling, orthopaedic biomechanics, imaging, biomedical engineering, and mechanobiology. He is the first author of 8 peer-reviewed journal publications, and 14 conference proceedings. He received Outstanding Graduate Student award from Michigan State University, Honorable Mention from Michigan OsteopathicAssociation’s Scientific Research Competition 2011, and Best Student Paper in Orthopaedic Biomechanics award from the American Society of Mechanical Engineers, Bioengineering Conference 2011.
