Paul Prusakowski (who runs this list) has an excellent video of transfemoral gait deviations. The older one was done by Northwestern University Prosthetic facility. It has been transferred into a fair CD by Seattle Prosthetic Research. There is a transtibial gait deviation video and CD developed at the Department of Physical Therapy at the Medical College of Georgia but I don’t believe it is available for sale; it might be if there were enough demand.
