Is chiropractic based on science or folklore?

Chiropractic is based on the scientific fact that your nervous system controls the function of virtually every cell, tissue, organ, and system in your body. Specific techniques are used to determine underlying causes of pain or imbalance and to treat them. Extensive medical research and patients experiences confirm that patients get measurable results from chiropractic. Over 30 million Americans received chiropractic treatment in 2003.
