Chiropractic techniques fit into 3 basic models based on the three body systems primarily addressed by chiropractors. Chiropractic intimately involves itself with the skeletal system, the muscle system and the nervous system. Therefore, while all chiropractic techniques involve all three systems, the techniques themselves can be differentiated from one another based on their method of assessment and their method of correction.
Segmental or skeletal system centered chiropractic techniques adjust vertebrae that are not in their optimum position back to a more normal position and, in so doing, affect the nervous system first and then the muscle system next.
Postural or muscle system centered chiropractic techniques first involve putting tension or relaxation within the muscle system in order to allow an easier structural adjustment to take place. In so doing, this approach involves the muscle system first which then affects the skeletal system and then, finally, the nervous system.
