Adjustments or manipulations involve the minor movement of vertebrae in the spine. The objective is to realign the vertebrae that have moved out of place for reasons ranging from normal activity to trauma such as an accident.
When the vertebrae are out of place, it has an overall systemic effect on systems ranging from muscular to the central nervous system. Without the proper alignment and flow of all nerves and systems in the body from the brain, problems can arise with pain or functioning.
An adjustment or manipulation can be pressure from the chiropractor using his hands or tools/instruments to move the vertebrae back into their proper place. This happens with a fast movement and usually doesn’t cause discomfort. You might hear a noise like light pops and this is referred to as joint cavitation. It is the release of gasses like oxygen or nitrogen from the joint.
In general, adjustments are an excellent way to keep the body functioning at peak levels as well as treat a range of pain problems and dysfunction.
