Adjustments sometimes referred to as manipulations, are the minor movement of the vertebrae in the spine. The objective of this movement is to realign vertebrae that have moved out of place for a number of reasons ranging from normal daily activity to trauma, such as a car accident.
When vertebra are out of place there is an overall systemic effect from the muscular system to the central nervous system. Without proper alignment and flow between the nerves and the many systems of the body, we cannot function at our peak.
An adjustment is often a pressure from the chiropractor utilizing their hands or an instrument to move a vertebrae back into place. This happens with a quick movement and is often without any discomfort. You may hear a noise that sounds like you are cracking your knuckles, called joint cavitation, which is the release of gases such as oxygen and nitrogen from the joint.
