My former chiropractor (who is now deceased) was president of the Applied Kinesiologists Association, and wrote books on the subject. I have to say, my treatments were very slow, and involved a lot of laying on blocks, and not a lot of cracking. The diagnostic tests were weird, and involved pressure applied by him to specific points on me, which would sometimes completely disable other parts of my body. Like, he would touch a point on my shoulder, and I wouldn't be able to lift my arm, no matter how hard I tried. This would show him where the weakness was, and where he should put the above mentioned block. At one point, I asked him if he was really applying the same amount of pressure to the "weak" side as to the "strong" side. I honestly couldn't tell myself. He assured me he was, and that the differences I was feeling was due to my inbalances, not his pressure. I really couldn't tell for sure, and so I was always a little suspicious of the technique.

I was seeking treatment for migranes, and it did work, but so does the plain old cracking my plain old (new) chiropractor does, and now I only go about once a year, and I don't get migranes anymore. I was going monthly for the other treatments, with the same result. Oh, and I was put on an herbal supplement to raise my low blood pressure, and that had some very ugly side effects (like it turned me into what rhymes with witch).

My new chiropractor told me that my former doctor was quite famous for the work he did with Autistic children, and I have no doubt that he was sincere in his beliefs in the method. Was it quackery....maybe, but I never doubted his integrity.
