Adjustments, or manipulation as they're sometimes referred to, are the movement of the joints to return proper motion to that area of the spine.
The objective of this movement is to recreate proper motion that has been lost due to trauma, accidents, stress, poor posture, lack of movement, and so much more.
When there is a lack of motion there is a lack of full communication from the brain to the body, this has an overall systemic effect from muscular to the central nervous system. Without proper movement and flow of all nerves and systems in the body from the brain, we can't function at our peak.
An adjustment is often a pressure from the chiropractor utilizing the hands or an instrument to restore motion to the spine. This happens with a quick movement and is often without discomfort. You may hear a noise that sounds like you're cracking your knuckles referred to as joint cavitation. It is the release of gases such as oxygen and nitrogen from the joint.
Overall, adjustments are an excellent way to keep the body functioning at its highest level. When the body is in full motion, the body is able to respond and perform as it was designed to.
