"Osteopathic manipulations integrate purposeful give-and-take of the whole body as an interconnected system. OMM takes chiropractic steps further beyond just bones, joints, and the spine, and is the foundation of osteopathy from the holistic sense."

OMM is one of the foundations of osteopathic medical school curricula. If you're a DO, don't think that the interviewer just wants to see if you know what OMM is. You do. Instead, what you want to convey is that knowing how OMM techniques can supplement conventional medicine is more important than merely listing out the bullet points of what these techniques are. Steering your answer toward what, specifically, are the advantages of OMM techniques over and beyond the MD-centric approach. You should espouse holism in your answer, especially. Then, if they really want you to list the techniques, you know them, so give them that, too.

"Osteopathic Manipulative Medicine supersedes chiropractic like osteopathy supersedes the sometimes narrow focus of medicine. I find that the accepted manipulation techniques of OMM that include other musculoskeletal structures besides just joints is what allows it to impact the physiological conditions outside of the musculoskeletal system."
