title: [Hypertrophy of the lateral head of the gastrocnemius muscle with spontaneous electrical activity].
abstract: A patient with chronic S-1 radiculopathy is discussed, in whom, after previous slight weakening of calf muscles, the lateral head of the gastrocnemius muscle was enlarged. Histopathological examination revealed in this muscle a true hypertrophy, mainly second type of muscle fibres. However electromyographic examination showed a continuous spontaneous electrical activity at rest (pseudomyotonic discharges) which, according to the authors, explain the found signs.
