[Electroneuromyographic study of the spastic-ataxic syndrome in multiple sclerosis]

Electroneuromyographical studies were performed in 39 patients with atactic-spastic and mixed forms of disseminated sclerosis. The examinations detected a drop in the velocity of impulse conduction along the tibial nerve in spastic forms and an increase in the velocity of impulse conduction along the medium nerve in atactic forms. The most pronounced were changes in velocity of afferent conduction. The data obtained were compared with electroneuromyographical studies in atactic and spastic syndromes of different origin.
