title: [Peculiarities of electrophysiological pattern of the extensor digitorum brevis muscle. Its importance in neurologic diagnosis].
abstract: Fifty-five EMG records from the extensor digitorum brevis muscle were analysed in cases of lower motor neuron lesions, primary muscular diseases and in controls. In all patients with lower motor neuron disease denervation pattern was obtained from the muscle. In the control group the so-called neurogenic pattern was recorded in 45% of cases, in the remaining subjects the findings were normal. In patients with primary muscular diseases denervation pattern was obtained in 45% of cases while in the remaining patients the changes were typically myogenic. In the control group and in patients with primary muscular diseases no correlation was observed between the age of the patients and the presence of neurogenic changes in the muscle. Presence of the so-called neurogenic pattern in the muscle may be due to the anatomical structure and position of the muscle which is particularly exposed to microtraumas in cases of primarily muscular diseases.
