I spent 12 years teaching basic sciences and 7 years as an associate dean at the an osteopathic medical school. However, since the school's faculty came from institutions throughout the United States, I doubt that what I observed differed much from the situation at other osteopathic schools.
Students carried a heavy curriculum in osteopathic manipulative therapy (OMT), beginning in their freshman year. The department of manipulative medicine was completely segregated from the other departments, both in principles and in practice. The osteopathic faculty members in the standard medical departments neither practiced nor taught OMT. Nor did the OMT faculty practice or teach the standard forms of medicine. It was as if OMT was a freestanding form of health care—one that, unlike other departments, was not necessarily bound by scientific foundations. Being a basic science researcher, I have made attempts to set up an animal model to objectively test the claim that certain harmful forms of sympathetic nerve traffic could be altered by spinal OMT. However, I never received any support from the osteopathic faculty in seeing such a study completed. The general attitude of the osteopathic manipulation physicians was, "since we already know it works, why should we bother with proving it."
