The Fascial Distortion Model (FDM) is an anatomical perspective, originated Stephen Typaldos, D.O. Dr. Typaldos described six principal types of fascial distortions, each with its own body language, signature presentation and likely outcome with and without Fascial Distortion Model treatments. He then tested his model over a period of almost 15 years and found that it held up exceptionally well. Initially he treated mostly acute injuries, which could be reversed almost instantaneously, but as the years went on, he tested his model on more and more difficult cases, some from injuries that had occurred 20 years earlier. The results were the same – dramatic and spectacular in most cases.
