In the YouTube video series above, Dr. Michael Bridges, professor of physical therapy, provides a background to the roles of a physical therapist and the physics principles they use on a daily basis. He examines typical joint injuries and describes how free body diagrams and mechanical advantage influence diagnosis and treatment. Finally, he discusses electric signals in the body and how they can be manipulated for healing.
