[Rheoencephalographic studies with head rotation tests in patients with ischemic stroke in the area of carotid arteries].

REG investigations were carried out with head rotation in 87 subjects, including 36 healthy controls and 51 patients with ischaemic strokes in the area of carotid artery vascularization. Determining the REG index it was found that in the patients the reaction to rotation was less frequent but more intense than in the control groups. Head rotation test in REG investigations may be useful for assessing the cerebral circulation and can demonstrate, sometimes, which rotation should be avoided by the patient.
