It's been said already that some chiropractors happen to also be good physio therapists.
I have a friend who is a chiropractor who eventually was forced to start her own clinic because she refused to do kineaseology (i'm pretty sure I spelled that wrong, but whatever).
That's the one where you lie down and hold up your arm and they push your arm down and ask you a question like "did something bad happen do you where you were a teenager" - depending on how hard it is to push your arm down in response to that question, they determine whether they're on the path to working out the trauma that's causing whatever your present health problem is (ie, if it's easy to push down, they're on the right track!).
They keep asking questions until they narrow it down enough that you are supposed to be able to figure it out. In my case apparently all my problems were caused by a falling out I had with a friend when I was 15... "so, did you have any falling outs with friends when you were 15? Right, well, that's the reason why you have a hip problem now you're 32!". Utter utter bullshit.
But she couldn't get a job in an established clinic because she wouldn't practice it!
