A recent study in the Annals of Internal Medicine reviewed research to determine if there was a link between stroke and spinal manipulation. They did not find evidence of causation.
The World Health Organization regards manual mobilization and or spinal manipulative treatment conducted by chiropractors to be a safe and effective treatment with few mild transient effects.
several extensive cohort studies and meta-analysis have found no excess risk of CAD (stroke), resulting in secondary ischemic stroke for chiropractics empty compared to primary care follow up
History taking, especially regarding the time of symptom onset is the single most important factor for detecting subtle symptoms of a CAD
Evaluation of risk factors such as hypertension, smoking, low cholesterol, recent infection, family history and connective tissue disorders and a new, one sided headache and upper neck pain and or signs of neurologic deficit such as double vision, slurred speech suggest the possibility of stroke and require immediate emergency medical referral.
