Neurophysiological evaluation of associated demyelinating peripheral neuropathy and multiple sclerosis: a case report.

A case of combined multiple sclerosis and demyelinating neuropathy is presented. Percutaneous electrical stimulation of the cortex and spinal cord has shown that pyramidal tract conduction time was prolonged and conduction velocity in the cord was 4 m/s. Motor conduction velocity in proximal segments of peripheral nerves was slowed to the same extent as in distal segments. [ABSTRACT FROM AUTHOR]
