Injury Prevention & Mobility Biomechanics
My research group uses the tools of biomechanics to develop and evaluate novel techniques for preventing disability and injury. We seek to generate new understanding of the risk factors for injury and mobility impairment, and to develop and test novel interventions. Most projects involve experimental measures of human movement dynamics, often combined with computer-based modeling efforts. For example, we are interested in understanding the relative importance of strength versus reaction time in affecting mobility and balance. A particular focus of the laboratory is the prevention of injuries in the event of fall (especially hip fractures, wrist fractures, and brain injuries). Here, we are designing and testing the ability of energy-absorbing floors and protective clothing (e.g., hip padding devices) to reduce impact forces and injury risk during falls. We are also examining the cause of age-related changes in fall protective responses (e.g., use of the hands to arrest the fall), with the aim of developing exercise-based therapies for fracture prevention. An increasing focus is monitoring movement patterns in the real-life environment, through miniature wearable sensors and video technology. Trainees are exposed to a combination of basic and applied research, including industry collaborations, and efforts to develop international testing standards. The lab has also developed several novel experimental techniques that are now being duplicated by former trainees and other research groups internationally.
