[Electromyographic findings in diabetics]

In 1987-1988 239 patients with diabetes type I and II were subjected to electromyographic examinations. The sensory and motor neurograms (n. suralis, n. medianus, n. peroneus, n. tibialis) were evaluated as well as myograms (from the m. opponens pollicis, m. tibialis, anterior, m. soleus). In all patients a priori other possible neurotoxic influences were ruled out; the age of the patients did not exceed 60 years. Abnormal parameters of the evaluated neurograms and myograms were found also in all diabetics type II with a normal neurological finding. In type I diabetics this so-called electrophysiological neuropathy was found in the same group in 84.2% of the patients. The most sensitive nerve in diabetes in the authors' investigation was the n. suralis, the second most frequently abnormal finding was the motor neurogram of the n. peroneus. The authors did not find it possible to elaborate a scale of clinical-electromyographic correlation.
