title: [Electroneuromyographic characteristics of the initial manifestations of cerebral circulatory insufficiency].
abstract: A clinico-electroneuromyographic examination covered 50 patients with initial manifestations of cerebral circulation insufficiency. The results are compared with the electroneuromyographic characteristics of discirculatory encephalopathy (20 patients), transient disorders of the cerebral circulation (28 patients) and ischemic strokes (30 patients). The parameter of "the sum of maximum amplitudes of M-responses" in the musculi manus and musculi pedis upon stimulation of the median, ulnar, tibial and fibular nerves at both sides developed by the authors was found to be diagnostically effective. This parameter proved to be significantly decreased in all cases of initial manifestations of cerebral circulation insufficiency. With increasing severity of cerebral circulation insufficiency in ischemic stroke the parameter reduced to the minimal values in a step-wise manner.
