A 45-year-old man with dystonia of the legs was found to have cerebellar ectopia and syringomyelia. Both walking and passive movements of the big toes evoked dystonic postures of the legs. Electrophysiologic studies suggested that the dystonic movements were reflex in origin. We propose that the cervical spinal cord lesion, involving propriospinal pathways, resulted in an abnormal response of spinal interneurons to peripheral stimuli.

Abstract
A 45-year-old man with dystonia of the legs was found to have cerebellar ectopia and syringomyelia. Both walking and passive movements of the big toes evoked dystonic postures of the legs. Electrophysiologic studies suggested that the dystonic movements were reflex in origin. We propose that the cervical spinal cord lesion, involving propriospinal pathways, resulted in an abnormal response of spinal interneurons to peripheral stimuli.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
