I am interested in determining the incidence of cerebrovascular
complications caused by cervical manual therapy/manipulation. This includes
all professions using such techniques eg physios, osteopaths,
chiropractors etc.

I understand that the Swiss Association of Manual Medicine
retrospectively found the risk factor to be 1 in 400,000

Is anyone aware of any other studies or estimates of the incidence
of strokes related to manual therapy (current or completed)?
