I've had good results with physical therapy. Maybe that could be considered chiropracty lite?
When I was in my 30's, I went to a physician that did spinal adjustments, and they worked. He had me cross my arms while laying on his flat padded table, and then pretty much jumped with all his weight on my crossed arms. My back would pop like a series of popping buttons, but I felt better when he'd do it. And, he would sometimes do it for free, given I was a poor grad student. He wasn't a chiropractic, but he was a D.O. Don't think Osteopaths have been part of this discussion yet. They are legal in Oregon, I think there's a university here somewhere that churns out D.O.s
He was a very bright guy, and I could tell by his practice that he was getting insanely rich. Go figure I guess.
