Double-step repetitive stimulation in myasthenia gravis.

abstract：:A quantitative assessment was made of the firing characteristics of repetitive axonal discharges encountered during microneurographic recordings from human peripheral nerves. Spontaneous activity was recorded from 16 single axons using tungsten microelectrodes inserted percutaneously into fascicles of the median or pe...
