I was referring specifically to his comments about deaths... it must be applied across the board regardless of training/education.
And in my experience, every chiro ive seen has documented everything they do, assess my entire body, posture, stance etc, question my general ergonomics at home/work and dont try fix the problem in one go.
Ive got a hip alignment issue, partly due to many factors and well I dont have time to be a fitness addict unfortunately. My one leg is slightly shorter than the other as a result and chiro corrects this for me.
Chiro can potentially make things worse if the patient gives them incorrect information like going in with a herniated disc. If the chiro doesnt know about this, and they could make it a bit worse. But if known, they definitely wont. So as much as they can do harm, its up to the patient to be informed and we all know how ignorant most people actually are.
