  • Title: [Spinal mechanisms of movement disorders in torsion dystonia (electromyographic analysis)].
    Author: Novikova VP.
    Journal: Zh Nevropatol Psikhiatr Im S S Korsakova; 1979; 79(3):298-304. PubMed ID: 442898.
    Abstract:
    A clinico-electromyographical study of 25 patients with torsion dystonia was carried out. The author studied evoked responses of the muscles of the lower extremities (H-reflex, M-response, F-wave) during the electric stimulation of the tibial nerve and the general electric muscular activity both at rest and in hyperkinesia. Two types of changes in the electromyographic data were revealed in the examined patients. It is suggested that there are certain differences in the neurophysiological mechanisms of motor disturbances in torsion dystonia. The role of the spinal apparatus in the development of dystonic hyperkinesia is considered.
