title: Cerebral Hemorrhage Following Chiropractic Activator Treatment - Case Report and Review of Literature.
abstract: BackgroundDespite widespread utilization of chiropractic treatment for various ailments, there is a paucity of documentation regarding intracerebral hemorrhage related to chiropractic trauma. Stroke has been reported from cervical manipulation, although with a suggested low incidence. Activator treatment, an instrument that produces a high-velocity, low-amplitude impact to the spine, is considered especially safe. There are no prior reports of intracerebral hemorrhage resulting from a chiropractic activator treatment.Case DescriptionA 75-year-old woman was admitted to the hospital with a history of headaches, visual difficulties on the right, and speech disturbance of relatively acute onset. CT scan showed a brain hemorrhage in an unusual location. Extensive evaluation was undertaken because this was thought to be a spontaneous event. No cause was found on imaging. Subsequent history revealed a chiropractic activator treatment applied directly to the junction of the back of her head and the upper cervical spine immediately prior to the onset of symptoms. Her clinical course is described.ConclusionsThis appears to be the first report linking traumatic intracerebral hemorrhage with a chiropractic activator treatment. The use of this modality in an elderly population, with widespread utilization of anticoagulants and platelet inhibitors, is of potential concern.
