"...spinal manipulation applied by chiropractors is shown to be more effective than alternative treatment for low-back pain"– The Magna Study
The effectiveness of chiropractic has been repeatedly documented in studies from such groups as the AHCPR (Agency for Health Care Policy and Research;1994), Ontario Ministry of health (Magna;1993), Rand Corporation amongst others. It is widely accepted by insurance companies.
The RAND reports marked the first time that representatives of the medical community went on record stating that spinal manipulation is an appropriate treatment for certain low-back pain conditions.
Judge Getzendanner rejected the AMA's patient care defense, and cited scientific studies which implied that "chiropractic care was twice as effective as medical care in relieving many painful conditions of the neck and back as well as related musculo-skeletal problems." Since the court's findings and conclusions were released, an increasing number of medical doctors, hospitals and health care organizations in the U.S. have begun to include the services of chiropractors.
