[Electoneuromyography in the study of diseases of the neuromuscular system].
Results of electroneuromyographic examinations of 207 patients with hereditary neuromuscular diseases are presented. Patients with neural amyotrophies showed a sharp slowdown of the speed of impulse transmission along the median and the tibial nerves, a lowering of the induced potentials of the muscle and the nerve, and an increase of the M-response. In patients with spinal amyotrophies a slight lowering of the speed of the impulse transmission along the tibial nerves with the transmission speed along the median nerves being normal, a diminution of the amplitude and a shortening of the duration of the M-response, and an increase of the amplitude of the nerve action potentials were revealed. Patients with myodystrophies exhibited a slowdown of the speed of impulse transmission along the afferent fibres, and increase of the motosensor coefficient, a moderate lowering of the maximal with a tendency to a heightening of the minimal amplitude of the M-response and the nerve action potential.
