  • Title: [The adequacy of the rheoencephalographic method in clinical practice and research].
    Author: Anzimirov VL, Naumenko VI, Spirin BG.
    Journal: Zh Nevropatol Psikhiatr Im S S Korsakova; 1975; 75(11):1624-30. PubMed ID: 1210940.
    Abstract:
    For purposes of defining the adequacy of using REG registrations in clinical practice, the authors conducted 4 series of studies on normals (16 cases), in patients of a neurosurgical ward (39 cases) and in experimental animals (12 dogs). The experimental and clinical studies displayed that the mechanical pulse fluctuation of the skin was not the determining factor in the genesis of a REG. The authors have come to the conclusion that the time of distribution of the pulse wave by itself can not serve as an indicator of an extra-or intracranial origination of REG waves inasmuch as it is different in different brain areas and depending upon its remoteness from the heart and the state of the vascular tone. Using the occlusional cuff the authors calculated the portion of the extracranial item in the total amount of the wave amplitude in the REG in norms (in average 14%). Thus, the achieved data confirmed the adequacy of the REG as a method of studying the pulse blood flux and cerebral vascular tone.
