Hand-foot synkinesis in a patient with phenytoin intoxication
Abstract
Here we report the first case of phenytoin intoxication that was closely associated with hand-foot synkinesis. This case suggests a close association between cerebellar dysfunction and hand-foot synkinesis. In patients with hand-foot synkinesis, lesions of not only the secondary motor areas but also the cerebellum should be considered.
