Studies on the Safety of Chiropractic Care

A Canadian Study found that over a five-year period no deaths had been associated with Chiropractic care in Canada. The conclusion of this study estimated that the risk of serious neurological complications is 1 in 3 million adjustments. (“A report on the occurrence of cervical cerebral vascular accidents in chiropractic practice.” Journal of the Canadian Chiropractic Association, 1993; 37 (2): 104-6.)

Domestically, according to the Journal of Manipulative and Physiological Therapeutics, a study found not a single case of vertebral artery stroke or serious injury in 5 million adjustments performed at the National College of Chiropractic Clinic in Chicago. (“Complications arising from manipulation of the cervical spine,” Journal of Manipulative and Physiological Therapeutics 1980; 3: 213-19.)

The RAND corporation estimated that the risk of stroke from chiropractic adjustments was “one in a million.” (“The appropriateness of manipulation and mobilization of the cervical spine. Santa Monica, GA: RAND Corporation 1996: xiv. (6).)

Numerous studies have show that the risk of stroke from chiropractic adjustment is so small that it is statistically insignificant. So statistically insignificant in fact that it is estimated that more people suffer “beauty parlor stroke syndrome” (a stroke caused by your head being bent backwards into a washing basin) than Chiropractic related strokes.
