Chiropractic is from Greek words meaning done by hand. Doctors of Chiropractic are concerned with how the body’s nerves, muscles and joints function as a whole. They focus on the diagnosis, treatment and prevention of mechanical disorders of the body. They are specialists in using manipulations of joints to improve range of motion, flexibility, and to restore proper function. Chiropractic is one of the most popular alternative therapies currently available. Some would say it now qualifies as mainstream treatment as opposed to complementary medicine. Chiropractic treatment is covered by many insurance plans. It has become well-accepted treatment for acute pain and problems of the spine, including low back pain and whiplash.
