Ok, first - Please do not let this degenerate into a flame war. I honestly would like to know the answer to this, and I do not know enough about either type of treatment to even form an opinion, so if I am wrong about something - I am sorry. The general trend in a lot of previous DO vs. DC threads is the belief that chiropractic medicine is often unsupported by solid evidence, where as OMT has a broad base of scientific support for many treatment types. So, how does OMT differ from Chiropractic medicine in treating something like sciatica or low back pain? I know that the chiropractic treatment would be to align the spine, correct the 'subluxation', and problem solved. But if this treatment has little scientific support, what would OMT offer that is both different and empirically superior. Also, I know there are like a zillion and one 'DO vs DC' threads, and one of them may touch on this topic, but I was unable to weed through them all to find an answer b/c most of them end up as pi$$ing matches between the two fields that seem to go on forever.
