Abstract

Electrodiagnostic studies were carried out in 31 patients with neurological complications of AHC, who were seen at Seoul National University Hospital from August 1981 to February 1982. Age of the patients ranged from 14 to 62 years. Both velocity and distal latency of motor and sensory conduction were normal in the nerves innervating the affected muscles. During the acute phase of motor paralysis, there was an absence of electrical activity in completely paralysed muscles. In partially denervated muscles, there were polyphasic motor unit potentials of normal duration and amplitrde on weak contraction and reduced interference on maximal effort. From the third or fourth week onwards, fibrillation potentials and positive sharp waves at rest were observed in paraspinal muscles in most cases. All the above findings were supporting the view that the principal site of involvement for the paralytic phenomena is at the level of the anterior horn cells or anterior roots.
