Jason Long, PhD

I have over twenty years’ experience in motion analysis and biomechanical modeling, focusing on the assessment of lower extremity kinematics and kinetics during ambulation. My previous research has dealt with perturbations in gait associated with lower limb disorders, with a focus on cerebral palsy and foot/ankle pathology. I employ 3D kinematic assessment and inverse dynamics modeling to quantify biomechanical changes in gait for patients undergoing conservative or surgical intervention.
