Charcot-Marie-Tooth disease: case report of electroneuromyographic abnormalities.

This patient showed many of the major clinical signs and electroneuromyographic features found in Charcot-Marie-Tooth disease. Electroneuromyographic examination revealed the characteristic severe slowing of conduction velocity and neuropathic muscle potentials. The electromyographic abnormalities correlated fairly well with muscle function, although muscle strength in general was surprisingly stronger than was anticipated. Goodgold and Eberstein have noted that dramatic slowing of conduction velocity cannot be directly related to severity of clinical symptoms. This patient seemed to demonstrate this principle.
