Walking Performance Improvement Following Revascularization Treatments in Patients with Peripheral Artery Disease

Project Description: The overall aim of this study is to understand how walking performance and gait biomechanics change following revascularization treatments. Patients with peripheral artery disease undergo either bypass surgery or endovascular/stenting surgery and are evaluated before and after six-months of surgery. We use advanced biomechanical tools to quantify the outcomes following the surgery. We also compare the preoperative and postoperative ambulatory function and gait biomechanics between bypass surgery and endovascular surgery for pain free and pain walking conditions in patients with peripheral artery disease.
Gait mechanics of children with Cerebral Palsy

Project Description: We are investigating pre- and post-operative changes to walking mechanics following correction of knee flexion deformities in children with Cerebral Palsy (CP). Using motion capture, foot pressure, muscle activity, and metabolic tools we gain a wealth of information on how a patient walks. Our clinical collaborators at Children’s Hospital & Medical Center use these data to inform their surgical plan. In addition, we can objectively track improvements to overall mobility.
