Motion Analysis


The Herrick-Davis Motion Analysis Laboratory studies the dynamic function of human joints and mechanical factors that are associated with degenerative joint and soft tissue diseases.

The Motion Analysis Laboratory has developed a unique high-speed X-ray system to measure dynamic joint function. This system enables direct 3-D visualization and measurement of joint motion with extremely high accuracy. Imaging data is supplemented with simultaneous measurement of forces, neuromuscular function (EMG) and whole-body motion. Combined with complex computer models, this enables 3-D visualization as well as characterization of musculoskeletal loading and behavior during movement.

On-going studies are aimed at understanding how the treatment of rotator cuff tears affects long-term shoulder function, the impact of fusion and artificial disc replacement on spine motion, and the effects of surgical reconstruction techniques on knee and elbow function.
