Abstract
A case reported in this paper showed peculiar seizures induced by sudden voluntary movements of the leg. The seizures were tonic or torsionlike spasms which was initiated in the unilateral lower extremity, preceded by abnormal sensation in the sole of the foot, and then followed by tonic seizures of the upper extremity on the same side. His consciousness was clear throughout the attack, the duration of which was about thirty to sixty seconds. The general physical examination and neurological examination revealed no abnormality and the laboratory examination was normal.
E. E. G. and pneumoencephalogram showed no thing abnormal. Diphenylhydantoin and phenobarbital was given to the patient, which was followed by complete disappearance of seizures. Several cases which seemed to be identical to the above patient have been reported in the literature. There are various different opinions on the pathogenesis and the name of the diseases, but a dysfunction of the basal ganglia is considered the most probable factor because of the characteristic features of the seizure and of the intact consciousness.
