[Electromyographic characteristics of the neuromuscular disorders in botulism].

The total bioelectrical activity of the muscles of the upper extremities as well as the neuromuscular transmission were examined in 30 patients with botulism at various stages of the disease. A picture of low-amplitude interference electromyogram was revealed. The results of stimulation electromyography pointed to a peculiar disorder of the neuromuscular transmission associated with a defect in the mediator release. Dynamic clinical and electromyographic observations pointed to a long period of the motor function restoration in convalescents.
