When everything is working properly, humans can perform high-demand activities of daily living for more than 100 years. This rarely happens. One of the greatest barriers to realizing this potential is pathology of the musculoskeletal system. Joints are critical elements for enabling complex movements between segments, and they are remarkable in their ability to facilitate motion while transmitting forces; however, changes due to disease and injury interfere with mechanical function. Clinical interventions aim to alter joint mechanics; however, a lack of information on how healthy joints function during dynamic loading and whether interventions effectively alter joint mechanics as intended limit the ability to optimize treatments. 

The purpose of this work is to use biplanar videoradiography to directly measure a person’s specific anatomy in motion while they perform high-demand activities. Precise information describing the motion of the skeletal system coupled with full-body musculoskeletal modeling approaches may provide insights into joint function and health.
