Blind-Spot Mapping, Cortical Function, and Chiropractic Manipulation

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.

A member of Quackwatch’s Healthfraud discussion list recently reported from a health fair:

No, a quick glance at their website makes it seem that they are not legitimate, and a more detailed examination confirms that initial impression. (more…)

Chiropractic and Deafness: Back to 1895

Chiropractic originated in 1895 when D.D. Palmer claimed to have restored deaf janitor Harvey Lillard’s hearing by manipulating his spine. This makes no anatomical sense, and few if any chiropractors claim to be able to reverse deafness today. But now a chiropractic website is attempting to vindicate D. D. Palmer. They list deafness among a long (wrong) list of “Conditions That Respond Well to Chiropractic”

They list 6 supporting studies. Three are case reports, two are case series, and one is a review of the literature that is labeled in its title as “A Search to Validate” D.D. Palmer. (more…)
