ADJUSTMENTS/ MANIPULATION
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 made by the chiropractor can be accomplished in several ways. Traditional chiropractic adjustements consist 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.
An adjustment can be accomplished using what is called a "drop table" which assists the chiropractic physician in correcting the abnormal motion of the vertebra in question. The table makes a banging noise and patients are advised in advance to expect the noise as a normal part of the adjusting process.
Adjustments can also be accomplished with either a handheld or computer assisted instrument. The handheld instrument is known as an Activator but is often referred to by patients as a clicker. It uses a controlled mechanically generated thrust to adjust the vertebra. It is usually performed with the patient lying face down on the table.
Computerized adjusting instruments are the 21st century's approach to chiropractic. Please look at the page on the PulStar Instrument to get a more detailed description of this wonderful new approach to chiropractic care.
