ADJUSTMENTS
The term "adjustment" refers to the specific manipulation chiropractors apply to vertebrae that have abnormal movement patterns or fail to function normally. The objective of the chiropractic treatment is to reduce the subluxation, which results in an increased range of motion, reduced nerve irritability and improved function.
The adjustment can be made by the chiropractor in a variety of ways. One technique consists of a high velocity, short lever arm thrust applied to a vertebra, which is often accompanied by an audible release of gas (joint cavitation). The audible sound is caused by the release of oxygen, nitrogen, and carbon dioxide, which releases joint pressure (cavitation). The sensation is usually relieving, though minor discomfort has been reported (that usually lasts for only a short time duration) if the surrounding muscles are in spasm or the patient tenses up during the chiropractic procedure.
The adjustment can also be done with low force or no force techniques which do not have the accompanying sound of the "pop" that is found in the faster techniques. These techniques are available for the older patient or the patient that may be concerned about the high velocity adjustment. While these techniques work as well, they may take longer to affect a change but may well be worth it for you if you are concerned about the "popping" noise.
