Our Projects

Subject Specific Concurrent Simulation of Movement and Natural Knee Contacts Mechanics

This project combines custom muscle driven musculoskeletal models with subject specific geometries and gait data to predict patient specific loading on knee structures and tissues during ambulation.

Validation of Musculsokeletal Models with Instrumented Prosthetic

The purpose of this project is to validate the knee contact force predictions of our custom muscle driven musculoskeletal models.

Our Lab

The Mizzou Motion Analysis Center (Mizzou MAC)

The mission of the Mizzou MAC is to combine the tools of engineering (computational analysis, instrumentation, measurement, and mechanical design) with the clinical expertise of physical therapy and orthopaedics to address issues of musculoskeletal health.
