The basic theme underlying this research program is that the identification and understanding of basic injury mechanisms will lead to the development of more effective and efficient clinical interventions and prevention strategies. To this end, investigations evaluate the kinematic, kinetic and muscular actions associated with human movement, the pathomechanics of orthopedic disabilities and issues related to rehabilitation of the musculoskeletal system . Through the use of advanced imaging techniques, functional biomechanical measurements, and musculoskeletal modeling, the various research projects in this program contribute to a better understanding of the causes of various orthopaedic conditions.

Although recognized as one of the most common lower extremity disorders encountered in orthopaedic practice, the etiology and treatment of this condition remains elusive and highly controversial. We are currently conducting several studies aimed at understanding the pathomechanics of patellofemoral joint dysfunction. In particular, we are evaluating how abnormal lower extremity mechanics may contribute to elevated patellofemoral joint forces and stresses in this population. To test our hypotheses, we are utilizing patient specific models of the patellofemoral joint, dynamic imaging, and finite element techniques. The long term goal of this research is to use biomechanical data to develop a classification system for persons with patellofemoral joint dysfunction and to conduct clinical trials to establish the efficacy and cost effectiveness of various interventions (surgical and non-surgical).
As female participation rates at all levels of sporting activity have dramatically increased, so have certain sports injuries. In particular, the incidence of ACL injury in female athletes has been reported to be 4 to 6 times greater than male athletes participating in the same sports. The purpose of this line of research is two-fold: 1) to quantify gender differences in biomechanical and neuromuscular aspects of sport specific movements, and to determine how gender specific movement patterns vary across different stages of maturation, and 2) to assess the influence of a training program in altering biomechanical and neuromuscular aspects of movement in female athletes, and determine whether a given response to a training program varies across different stages of maturation. By better understanding the biomechanical and neuromuscular factors that may place the female athlete at risk for ACL injury, we hope to provide a foundation on which further investigation of injury prevention and rehabilitation can be based.

Slipping is one of the most common causes of falls, and has been reported to account for approximately 62% of underfoot accidents in the workplace . In conjunction with Sub-committee F-13 (Safety and Traction for Footwear) of the American Society of Testing and Materials, we are investigating issues related to the evaluation of utilized and required friction, and devices used for the evaluation of pedestrian traction (tribometers). In addition, we are evaluating the influence of footwear sole hardness on slip initiation and recovery in young adults The long-term goal of this line of research is to provide objective data for the development of standards for safe walkway surfaces.
