  • Title: [Diagnostic value of electromyography in revealing the laterality of the motor deficit in brain tumors].
    Author: Saradzhishvili PM, Maruashvili MG, Baratashvili NN.
    Journal: Zh Nevropatol Psikhiatr Im S S Korsakova; 1984; 84(5):641-4. PubMed ID: 6331690.
    Abstract:
    Electromyographic studies of anterior tibial muscles supplemented by simultaneous induction of Babinski's reflex indicated the appearance of bioelectrical activity in the extremities contralateral to the tumour which suggested the generalization of tone alterations and helped determine the laterization of the pathological process even when there were no clinical manifestations of motor deficit. Having analyzed their own and literature data, the authors came to the conclusion that the contralateral response observed on the electromyogram in the form of prolonged bioelectrical activity with simultaneous appearance of tonic tension in the crus flexors in the absence of clinically evident motor deficit is explained by the presence of the crossover protective reflex on the spinal level.
