Adjustments are the minor movement of vertebrae in the spine. The objective is to realign vertebrae that have moved out of place for various reasons. Without proper vertebral alignment and nerve flow of all the cells and tissues of the body are unable to function at their optimal healing potential.
An adjustment is gentle pressure from the chiropractor to move a vertebrae back into place. This happens quickly and more often without discomfort. The cracking noise you may hear is the release of gases from the joint.
Adjustments are an excellent way to keep the body functioning at its highest level possible. When the body is in alignment, the body is able to respond and perform as it was designed to.
