Axial myoclonus of propriospinal origin.

Journal article

Three patients are described with nonrhythmic repetitive axial myoclonic jerks causing symmetric flexion of the neck, trunk, hips and knees. No electrophysiological evidence of a cortical or brainstem reticular origin for the myoclonus was found. In the first patient the axial jerks only occurred spontaneously. The latencies of recruitment of spinal segments during a jerk indicated that the discharge arose in the mid thoracic cord and then slowly spread at about 5 ms-1 up and down the cord to...
