Just to get back on original thought and question by 611...
OMM and chiro manipulation are similar. If anyone ever even bothered to study up on the history, you would find that the founder of chiro was also a student of ATStills. I think his name was Something Palmer... samuel palmer? whatever.
I hope that info help you 611 on the origin of chiropractic medicine.
The difference? I believe most chiro treat low back pain, or pain relating to your thoracic or lumbar region, maybe some other regions as well... however, never heard of other regions before besides the back and stuff. So if you injured your back during work, herniated disc, car accident... people usual go to a chiro to get treatment, manual manipulation, and electric.
However... you don't go to your chiro if you have a cold, or if you have sinusities, cervical radiculopathy, pneumonia, headaches, GI immotility, etc. the list goes on and on. Can you treat these disorders with OMM ??? Sure you can. I am not going to describe all the different techniques to treat every specific symptoms because I might as well tell you to buy the book, but whoever is in a DO school will know that you can treat it.
Just for those who are skeptical about OMM treatment of stuff like colds, asthma, pneumonia, etc. then I would suggest either you practice some OMM on real patients or learn some OMM. =)
Do either have scientific basis? Yes... they all do except cranial techniques at the moment. I don't know how many chiro's practice cranial.
Now back to what everyone else was fussing about...
Chiros are doctors... and in my sense, they are physicians treating disorder of the back relating to back pain. I mean.. what do you call someone who does surgical operation on the brain? ANS... NEUROSURGEON!!! Very good! What do you call someone who cracks back and fixes back pain? ANS... CHIROPRACTORS..!!! Very good again!
Get the point?
For all I know, I don't think it is misleading if chiro dliploma saids "doctor of chiropractic medicine" because chiropractics is a form of medicine similar to how osteopathic IS a form of medicine.
