Chiropractic care is grounded in the principle that the body can heal itself when the skeletal system is correctly aligned and the nervous system is functioning properly. To achieve this, the practitioner uses his or her hands or an adjusting tool to perform specific manipulations of the vertebrae. When these bones of the spine are not correctly articulated, resulting in a condition known as subluxation, the theory is that nerve transmission is disrupted and causes pain in the back, as well as other areas of the body.
Chiropractic is one of the most popular alternative therapies currently available. According to the National Institutes of Health's National Center for Complementary and Alternative Medicine (http://nccam.nih.gov/) about 20% of Americans report having used chiropractic care at least once. Chiropractic treatment is covered by many insurance plans, including Medicare.
