Professional Interests

Dr. Susan Sigward’s research focuses on the identification and amelioration of impaired mechanics as they relate to lower-extremity injuries, with a focus on knee injuries. Her work has contributed to the understanding of how factors such as experience, age, training and sex influence the development of movement strategies that contribute to anterior cruciate ligament (ACL) injuries. Current studies are focused on rehabilitation following ACL reconstruction, with an emphasis on the effects of early rehabilitation interventions on long-term outcomes. Dr. Sigward is director of the division’s Human Performance Laboratory at the Competitive Athletic Training Zone, Physical Therapy Institute and Sports Performance Center in Pasadena, Calif.
