Category Risk from health interventions

There is some anecdotal evidence that spinal manipulation causes arterial dissection and stroke. In fifteen years of practice a client has never been injured by spinal manipulation in my practice. Every five minutes someone in the UK will suffer a stroke, some of these people will have visited their chiropractor. One of the anecdotes was a person who had been treated by a chiropractor for a sprained ankle, however it was assumed the chiropractor had manipulated the persons cervical spine and made those popping sounds.
