Steven Novella recently wrote about so-called “chiropractic neurology” and its most outspoken proponent, Ted Carrick. In 2005 I published an article in The Scientific Review of Alternative Medicine (Vol 9, No 1, p. 11-15) entitled “Blind-Spot Mapping, Cortical Function, and Chiropractic Manipulation.” It was an analysis of a study Carrick had published.
Carrick read a shorter, popularized version of my critique in Skeptical Inquirer and responded with a diatribe that was inaccurate, distorted what I had said, and accused me of fraud, deception, and mis-representation. He failed to offer a credible rebuttal of my specific criticisms; and, in my opinion, showed that he failed to understand some of my points. He referred to me as “Ms. Hall” and suggested that I was psychotic. He characterized my e-mail correspondence with him as “bizarre, rude, and offensive.” It was none of those, and I have copies of the e-mails to prove it. Carrick says he “forwarded it to the legal council for the American Chiropractic Association for review.” Now that strikes me as bizarre.
I am re-publishing the entire text of my article here as an instructive example of what passes for science in the chiropractic neurology community. Readers can judge for themselves whether my critique amounts to fraud and whether I am showing signs of psychosis, whether Carrick is a good scientist and whether his reply to my critique was appropriate.

Despite quackademia, anti-vaccine propaganda, and other discouraging trends, the news is not all bad. A major HMO has taken a decisive action in support of science-based medicine.
Kaiser Permanente Mid Atlantic States and Mid-Atlantic Permanente Group recently announced the elimination of neck manipulation from their chiropractic coverage. The revised policy states,
Given the paucity of data related to beneficial effects of chiropractic manipulation of the cervical spine and the real potential for catastrophic adverse events, it was decided to exclude chiropractic manipulation of the cervical spine from coverage.
Their decision was applauded by some but was predictably attacked by chiropractors. (more…)
I wonder how many people have heard that chiropractic neck adjustments can cause strokes. It isn’t exactly common knowledge. One organization is trying to raise public awareness through signs on the side of city buses (Injured by a Chiropractor? Call this number) and through TV commercials. I had never heard about this phenomenon myself until a few years ago, when I heard it mentioned on an episode of Alan Alda’s Scientific American Frontiers. I questioned his accuracy, but I quickly found confirmation in the medical literature.
A typical case was that of 24 year old Kristi Bedenbaugh who saw her chiropractor for sinus headaches. During a neck manipulation she suffered a brain stem stroke and she died three days later. Autopsy revealed that the manipulation had split the inside walls of both of her vertebral arteries, causing the walls to balloon and block the blood supply to the lower part of her brain. Additional studies concluded that blood clots had formed on the days the manipulation took place. The chiropractor later paid a $1000 fine. (more…)
