A chiropractic physician uses experience gained from clinical training to perform meticulous, methodical, and highly skilled hands-on manipulation. The hands are usually used since chiropractic is largely a manual procedure, but sometime an instrument might also be used. The joints are manipulated, and the spine is especially the core focus. The treatment is always controlled and customized differently for each patient; depending on the nature of his complain. The results are always positive and lasting.
