The most critical part of a chiropractic treatment is the chiropractic adjustment. This works on the premise that a joint, any joint in the body, is not moving to its full capacity. It may be restricted by tight muscles, inflammation or simply a mal-position of the joint. By applying a quick but gentle force through the joint, primarily using the chiropractor's hands, the affected joint is allowed to move with greater freedom through an appropriate range of motion, reducing pain and restoring joint movement. This can also relieve any secondary effects felt through the nervous system, since the nerves exiting your spine at each level have a large potential to be irritated by restricted joints and inflammation. You may or may not hear a “pop” noise during your adjustments, which is simply the result of a release of gas within the joint due to a change in pressure, which is perfectly normal.
