"Currently, the evidence is weak for an association between cervical spinal adjustments or manipulation (CeSAM) and cervical vascular accidents (CeVA), and the available data suggest no causal effect from CeSAM. With the change in law and the introduction of the Montgomery ruling in 2015, it is imperative to recognise that a direct or indirect association or causal link between chiropractic adjustments and CeVA is no longer relevant."

"According to peer-reviewed literature, Chiropractic adjustments are still associated with a risk factor. However, is this a balanced view? Many articles report the most serious adverse effects, but few report the positive impact of appropriate referral. This paper covers three such cases. We encourage those who have used the neurovascular screening criteria, identified a potential CeVA, and made the appropriate referral to the hospital to document their experiences, providing a balance to the discussion."
