My main failure to comprehend with OMM is that I don't think it's reasonable even when it does work. You do OMM for like 10 minutes on a patient and make their pain or dysfunction lessen for a day. This is not reasonable to compare to that of say a physical therapist who is committed to doing therapy all day and the patient can have multiple sessions without disrupting my capacity to see patients with more serious concerns and needs.
OMM is the thin string that allows the 30 or so DO schools in this country to remain open, it allows the people who work at these schools to remain employed, it allows those of us who are students to become physicians. What seems like a small thing is a very big deal. If it wasn't for OMM, every single DO School would shut their doors.
