A Canadian study indicates there is no increased risk related to chiropractic treatment in the heated debate about whether neck adjustments can trigger a rare type of stroke.

Researchers say patients are no more likely to suffer a stroke following a visit to a chiropractor than they would after stepping into their family doctor's office.

The findings, published today in the journal Spine, help shed light on earlier studies that had cast a cloud on the chiropractic profession and suggested that their actions resulted in some patients suffering a stroke after treatment.

“We didn't see any increased association between chiropractic care and usual family physician care, and the stroke,” said Frank Silver, one of the researchers and also a professor of medicine at the University of Toronto and director of the University Health Network stroke program.

“The association occurs because patients tend to seek care when they're having neck pain or headache, and sometimes they go to a chiropractor, sometimes they go to a physician. But we didn't see an increased likelihood of them having this type of stroke after seeing a chiropractor.”
