While it does seem to be significant in extent, we don't even know what the specific prerequisites are for MDs earning eligibility to enter a residency with osteopathic recognition beyond the following:
Prior to matriculation, residents meeting the requirements for V.A.2. or V.A.3. above must be prepared to demonstrate competence in osteopathic principles and practice approaching that of a graduating fourth-year student as established by the American Association of Colleges of Osteopathic Medicine (AACOM), including the following knowledge, skills, or behaviors:
V.B.1. osteopathic philosophy, history, terminology and code of ethics;
V.B.2. anatomy and physiology related to osteopathic medicine;
V.B.3. indications, contraindications, and safety issues associated with the use of osteopathic manipulative treatment; and,
V.B.4. palpatory diagnosis, osteopathic structural examination, and osteopathic manipulative treatment (OMT).
V.C. Competence must be demonstrated through achievement of prerequisite osteopathic principles and practice Milestones, including those specific to the specialty.
