By means of electromyographic and histologic methods, the authors studied severe muscular atrophy in seven patients affected by the apallic syndrome of different etiology. The EMG showed abundant spontaneous activity as fibrillation in all the patients, but usually motor conduction velocity and sensory potentials were normal in the nerves tested. Four patients underwent muscle biopsy that always showed a severe neurogenic atrophy; in two cases this picture was prominent in the type II fibers. According to the data in the literature, the authors believe that this muscular atrophy follows the impairment of the trophic control exerted by the central motor neuron on the peripheral one.
