A former osteopathic medical school faculty member wrote:
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."
Cranial therapy was a large component of the manipulative medicine department, both for patient care as well as for teaching the medical students. Interestingly, while the other faculty accepted most forms of OMT even though they did not use them, they did not endorse the use of cranial therapy. Indeed, I heard many criticisms of the practice by the non-OMT faculty. Their objections were the same as mentioned on Quackwatch -- that the cranial bones fuse early in infancy, after which no motion of these bones takes place. As you indicate, the alleged sensing of such motion forms the heart of cranial therapy.
I have never heard any attempt by an OMT practitioner to offer a tenable defense to such criticism. To me it almost seemed as if the OMT practitioner felt that the practice could not be defended with ordinary logic since its basis lay somewhere in the metaphysical and that only their gifted hands were able to "sense" the cranial motion.
But the seemingly metaphysical did not stop with the practice of cranial therapy. I know of one case in which a student with an undiagnosed illness consulted one of her OMT mentors who concluded that she had "a "hole in [her] aura."
