[Clinicoelectrophysiological aspects of hereditary amyotrophies].

In 100 patients with the neural and spinal forms of hereditary amyotrophies the potentialities of combined electrophysiological examinations (stimulatory, general, and local electromyography) were estimated. It is shown that the method of determining the speed of the impulse transmission along the afferent and efferent fibres of the peripheral nerves and the daily fluctuations of that speed may have an additional significance in diagnosing this pathology, A comparative analysis of the data obtained showed that the most informative was combined electrophysiological examination of the patient.
