Pilates is rooted in rehab. Its originator, Joseph Pilates, made a name for himself by using it for that purpose, even before coming to America.
A native German, he immigrated to Great Britain first and was, by a conspicuous twist of fate, interned on the Isle of Man during World War I. It was there, while working in a hospital, that he used exercises that strengthened him as a sickly youth to strengthen injured soldiers. And get this: many of the people he rehabbed survived the 1918 influenza epidemic!
Even today, researchers have shown how Pilates helps a number of musculoskeletal conditions, including knee injuries. Moreover, they have discovered how Pilates helps in rapid rehabilitation following surgeries. Brett R. Levine, an orthopedic surgeon in the Chicago area, demonstrated how patients were more satisfied with their total hip (THA) and total knee arthroplasties (TKA) after taking up Pilates before and after surgery.
The videos below show how Dr. Levine came to be involved in his research, and how confident he is that a dancer will benefit from Pilates after her ACL tore for the second time.
