Forced passive rotation of the atlas on the axis past 45 or 50 degrees stretches the vertebral artery. Normally, during active cervical rotation, all of the cervical vertebrae move together, a little movement in each joint, allowing about 80 degrees of rotation right and left. The atlantoaxial joint, where there is no intervertebral disc, is capable of about 50 degrees of independent rotation right and left, allowing excessive rotation during upper cervical rotatory manipulative techniques.

Neck Manipulation, Stroke, and the Vertebral Artery Stretch: Views, Opinions, and Options

Stroke reported as being associated with neck manipulation is rare when stroke numbers are tallied with the total number of neck manipulations performed, but the true incidence of this injury is not known and may be much greater than indicated by case reports. Advocating or providing neck manipulation without warning about the limitations and the danger of such treatment is irresponsible and...

Chiropractic and Spinal Manipulation Red Flags: A Comprehensive Review

Many people visit chiropractors’ offices seeking relief from back pain. Appropriate use of spinal manipulation provided by a chiropractor can be helpful in treating mechanical-type back pain, but there are good reasons to avoid chiropractic manipulation based on correction of “vertebral subluxations,” and there are red flags to look for before undergoing any kind of manipulative treatment for neck or back pain.

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 causation. My colleagues and I...

Chiropractic and Stroke: The question is not answered

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?...

Bias and Spin: Acupuncture and Chiropractic

We all construct our narrative based on our biases and spin the facts so that the narrative confirms our biases. Among other characteristics, what separates an SBM provider from a SCAM provider is realizing that biases are always active and apply to me as well as everyone else. My biases are simple: I am skeptical that humans can reliably understand reality without...

That’s so Chiropractic

Old bad studies: Fantastical autopsy results I found the following quote at “Chiropractic care can treat more than just bad backs” (FYI. Chiropractic can’t): Luse references a study published in The Medical Times authored by Dr. Henry Windsor [sic], M.D. that showcases the correlation of spinal health to overall wellness. Windsor dissected 75 human cadavers to investigate their causes of death. The...

A Statement on Cervical Manipulation and Dissections

The American Heart Association and the American Stroke Association recently published in the journal Stroke a thorough analysis of the evidence for an association between cervical manipulative therapy (CMT) and both vertebral artery dissection (VAD) and internal carotid artery dissection (ICAD). The full article is online: “Cervical Arterial Dissections and Association With Cervical Manipulative Therapy: A Statement for Healthcare Professionals From the...

Upper Neck Manipulation: Caveats for Patients and Providers

Chiropractors often deny that neck manipulation can be a primary cause of stroke by injuring vertebral arteries. But according to Jean-Yves Maigne, M.D., head of the Department of Physical Medicine at the Hôtel-Dieu Hospital in Paris, France: It is now a well established fact that cervical thrust manipulation can harm the vertebral artery. This accident was formerly regarded as very rare, although...
