The term “chiropractic” combines the Greek words cheir (hand) and praxis (practice) to describe a treatment done by hand. Hands-on therapy—especially adjustment of the spine—is central to chiropractic care. Chiropractic is based on the notion that the relationship between the body’s structure (primarily that of the spine) and its function (as coordinated by the nervous system) affects health.

Spinal adjustment/manipulation is a core treatment in chiropractic care, but it is not synonymous with chiropractic. Chiropractors commonly use other treatments in addition to spinal manipulation. During the initial visit, chiropractors typically take a health history and perform a physical examination, with a special emphasis on the spine. Other examinations or tests such as x-rays may also be performed. If chiropractic treatment is considered appropriate, a treatment plan will be developed.

During followup visits, practitioners may perform one or more of the many different types of adjustments and other manual therapies used in chiropractic care. Given mainly to the spine, a chiropractic adjustment involves using the hands or a device to apply a controlled, rapid force to a joint. The goal is to increase the range and quality of motion in the area being treated and to aid in restoring health. Joint mobilization is another type of manual therapy that may be used.

Chiropractors may combine the use of spinal adjustments and other manual therapies with several other treatments and approaches such as:

Heat and ice
Electrical stimulation
Relaxation techniques
Rehabilitative and general exercise
Counseling about diet, weight loss, and other lifestyle factors
Dietary supplements.
