Chiropractors have always sought to provide the safest and most effective healing methods for their patients. In order to achieve this, the chiropractic profession has been dedicated to conducting scientific studies to improve their diagnostic methods and treatment techniques. In the last 20 years chiropractic health care has established an impressive array of scientific research that demonstrates the efficacy, safety and cost effectiveness of chiropractic care. There are many further studies currently underway, and several have been performed by medical doctors and government researchers in both the U.S. and a number of other countries.

In fact, the chiropractic profession has accumulated a greater number of scientific trials on chiropractic than the medical profession has accumulated for many of the treatments rendered by medical doctors. According to David M. Edy, M.D., Ph.D., professor of health policy and management with Duke University, North Carolina, only 15 percent of all medical interventions are supported by solid scientific evidence. Paul G. Shekelle, M.D., M.P.H., of the RAND Corporation made the following statement on ABC's 20/20:
"There are considerably more randomized controlled trials which show benefit of this (chiropractic care) than there are for many, many other things which physicians and neurosurgeons do all the time."
