For some reason China has been putting out some great recent research on manual manipulation. This latest systematic review tackles a topic on which there is not a lot of published research: do patients benefit from manual adjustments for neck pain that is medically diagnosed as being primarily degenerative in origin? And even more interestingly, if the degeneration is causing pain into the arm? The answer is a resounding yes, and in relatively short period of time, a factoid that surprised even the researchers. So don’t let a diagnosis of cervical spine degeneration stop you from getting a chiropractic evaluation.
