The Psychosomatic Ischemia Test dates from 1954

Hyperemia is a localized blood flow that can notably be caused by ischemia followed by a sudden restoration of circulation. This physical phenomenon is at the origin of the creation in 1954 of the Psychosomatic Ischemia Test by psychosomatic medicine. This test uses for example the deflation of a sphygmomanometer cuff acting as a tourniquet.
