"Today, the largest single contributor to chronic neck pain and overall spine pain are motor vehicle crashes. Of the six million injuries per year, about three million are whiplash-type injuries. Of those, 500,000 to 900,000 will develop chronic pain." A. Croft, Journal of the American Chiropractic Association, Feb. 2000, 37:2.

Other estimates state 43% will go on to have chronic pain as a result of whiplash. (Woodward)
