Announcing: Video Lecture Course on Science-Based Medicine

A couple of years ago, the James Randi Educational Foundation commissioned me to develop a series of 10 video lectures on Science-Based Medicine. After a lot of work and many vicissitudes, it is now available. The lecture titles are: Science-Based Medicine vs. Evidence-Based Medicine What Is CAM?

When Headaches Are a Pain in the Neck: Spinal Manipulation vs. Mobilization for Cervicogenic Headache

NOTE: Today we offer a double feature on the treatment of cervicogenic headache. My article is about a study that compared manipulation to mobilization; it is followed by retired chiropractor Sam Homola’s guest article on manipulation for cervicogenic headache. The two posts complement each other and also complement my post from last week on the possible risk

Chiropractic and Stroke: No Evidence for Causation But Still Reason for Concern

Can neck manipulation (by chiropractors or by other practitioners) cause strokes? Many of us think it can, but definitive proof is lacking. A recently published study looked at the available evidence. A systematic review found a small association between stroke and chiropractic care but concluded that the association was spurious and that there was no evidence for

Update: Chiropractic Neck Manipulation and Stroke

Can neck manipulation cause strokes? Most MDs and many chiropractors agree that it can, but some chiropractors disagree. The subject has been covered on SBM before: here, here, here, here, here, here, here, here, and here. We keep returning to the subject not because it is a common problem (it isn’t), but because it is

Chiropractic Strokes Again: An Update

The risk of stroke with neck manipulation has been addressed on SBM before by Dr. Crislip, by myself, by chiropractor Samuel Homola, and by Jann Bellamy. I have listed the links at the end of this article for the convenience of interested readers. Recent studies merit a followup. A case report published in the Annals of Internal Medicine July 17,

Blind-Spot Mapping, Cortical Function, and Chiropractic Manipulation

Picture of the human retina; the bright spot on the right is the blind spot where the optic nerve leaves the eye. 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)

Kaiser Rejects Neck Manipulation

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

Chiropractic and Stroke

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
