Extreme rotation of the atlas on the axis (at the atlantoaxial joint) stretches the vertebral artery. In layman’s terms, 40% of a hanging.
I am off to Chicago for 5 days to wow the SMACC crowd with my ID/SBM acumen. I hope. Given that most of my multiple-personalities do not seem to be able to get any work done, I am forced to write a brief post this week, limited by the battery life on my MacBook Air. Whatever I get down on paper? pixels? RAM? before the battery dies as I fly over the Rockies will be the post. It is times like this I wish I had Gorskian typing skills.
SBM has discussed the many limitations of chiropractic: the low grades for entry into chiropractic school, the inadequate training, their reason d’être, subluxations and their adjustments being divorced from reality, the lack of efficacy of chiropractic for any process beyond low back pain (and even that is no better than safer interventions), the fondness of chiropractors for other useless pseudo-medicines, and their opposition to vaccines.
Hm. When I put it like that chiropractic does appear a little sketchy. But is chiropractic safe? It is a hands-on intervention, for a brief period of time applying the same force to the neck as about 40% of hanging from the neck until dead. So there is certainly the potential for chiropractic to cause harm. (more…)
One of the more frustrating things about practitioners who promote unsafe and scientifically discredited medical practices is their tendency to change their message for different audiences. One day they’ll tell you that they espouse only evidence-based practices and the next they’ll be promoting snake oil. This double talk is hard to combat, since to disprove them one would essentially have to provide a video of their contradictory remarks.
One day I participated in a series of business meetings with a CAM practitioner in attendance (he was an MD who graduated from UCSF). During one meeting he boldly proclaimed his support of scientifically rigorous research, and praised the Cochrane Collaborative’s efforts to provide systematic reviews of the evidence (or lack thereof) for various practices.
Several hours later we were sitting together in another meeting in which I objected to the publication of a consumer article that would assist parents of children with autism in finding a DAN! practitioner who could provide chelation therapy to their children. I explained that there was no evidence for the efficacy of such treatments, and plenty of evidence for their harm (including the death of at least one child that I’d read about in the news). I suggested that an article describing these dangers might be in order, but that an article encouraging chelation use for autism was simply unethical and I would not allow it to be published.
Instead of agreeing with me, the CAM MD suggested that I was being “narrow” and that I should allow consumers to “explore all their options.” I was stunned. This was the same person who had just said that he fully supported scientific inquiry. So I asked him how he could say that he supported evidence-based medicine, and then turn around and ignore evidence at will – even at the peril of human life.
His response dumbfounded me:
“I am just as comfortable practicing within an evidence-based framework as I am outside it.”
