Professor Wand and colleagues state that although manipulation of the cervical spine is a common treatment option for muscular neck pain, it carries the risk of causing a bleed of the vertebral artery, which would result in a vertebrobasilar stroke. A population-based nested case-control design was used.15 Using the date of a case’s VBA as the reference date, we created a risk set of all members of the population matching the case on date of birth and sex and simultaneously eligible to be a case as of the reference date. Chiropractic and Stroke: Association or Causation? Yes, Does case misclassification threaten the validity of studies investigating the relationship between neck manipulation and vertebral artery dissection stroke? And other factors should be considered, like the many “smoking gun” cases and whether there is any conclusive evidence of benefit to set against the possibility of risk.

Chiropractic Neck Manipulation and Stroke: What’s the Risk? It seems plausible that gentle mobilization techniques would be less likely to cause a vertebral artery tear than high velocity low amplitude (HVLA) manipulation techniques. Note that that neck pain is not even on the list. The research also suggests that spinal manipulative therapy may exacerbate pre-existing vertebral artery dissections. Stroke is a leading cause of serious long-term disability, with an estimated 5.4 million stroke survivors currently alive today.
