Chiropractic is a health care discipline which emphasizes the inherent recuperative power of the body to heal itself without the use of drugs and surgery. The practice of chiropractic focuses on the relationship between structure (primarily the spine) and function (as coordinated by the nervous system) and how that relationship affects the preservation and restoration of health.

the nervous system is the master controller of all living cells, tissues and organs; orchestrating and coordinating all cellular functions. The spinal column encases the nervous system (spinal cord and nerve roots) and is responsible for its protection.
Because of this intimate relationship, biomechanical and structural problems in the spinal column can irritate parts of the enclosed nervous system. This irritation can result from noxious inflammatory biochemicals released during tissue injury or may result from direct mechanical pressure. In either case, the functioning of the nervous system is negatively influenced as is the functioning of the cells, tissues and organs which are supplied by the affected nerve(s).

A vertebral subluxation is a complex of functional and/or structural and/or pathological articular (joint) changes that compromise neural integrity and may influence organ system function and general health.
Using a number of unique and highly refined skills, the chiropractor checks the patient's spine for any misalignments, fixations or other abnormalities (vertebral subluxations). If subluxations or other abnormalities are detected, the chiropractor will generally apply a gentle force in a corrective manner to the affected spinal area.
Chiropractors use many specialized techniques to identify and treat these spinal abnormalities and optimize overall health. In addition to spinal adjustive techniques, soft tissue techniques such as massage, dietary and nutritional counseling, physical therapies, and lifestyle modification programs are commonly employed.
