Propriospinal myoclonus in multiple sclerosis.
نویسندگان
چکیده
The clinical and electrophysiological features of segmental myoclonus affecting the right arm and upper trunk are described in a patient with multiple sclerosis. Electrophysiological studies suggested that the myoclonus was propagated from a generator site in the cervical cord, where lesions were found using MRI. The spread of electromyographic activity in each myoclonic jerk was slow and variable. These findings are characteristic of propriospinal myoclonus, which has not been associated with multiple sclerosis previously.

PROPRIOSPINAL MYOCLONUS (PSM) IS CHARACTERIZED BY FLEXION OR EXTENSION RHYTHMICARRHYTHMIC JERKS ARISING IN AXIAL MUSCLES AND SPREADING TO MORE CAUDAL AND ROSTRAL SEGMENTS. In PSM a spinal generator is believed to recruit axial and limb muscles via slowly conducting propriospinal pathways to produce the myoclonic jerks.1 Several cases of PSM have been reported and multiple sclerosis, cervical tr...
متن کاملTreatment of Propriospinal Myoclonus at Sleep Onset
Dear Editor, Propriospinal myoclonus (PSM) is characterized by jerks arising in axial muscles that spread to more caudal and rostral segments along propriospinal pathways. PSM at sleep onset is a subtype of PSM that occurs during the sleep–awake transition and causes severe sleep-onset insomnia.1 Previous case reports have focused on the etiology and mechanism of PSM, but have not evaluated tre...
متن کاملAxial myoclonus of propriospinal origin.
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 dis...

Propriospinal myoclonus is an unusual movement disorder. Here we reported a patient with electrophysiological data. The 32-year-old man had spontaneous, intermittent and brief jerks over the trunk, hip and lower limbs muscles for 4 years. The jerks were not sensitive to external stimuli and usually exacerbated whenever the patient felt relaxed, particularly preceding the onset of sleep. Electro...

The cause of propriospinal myoclonus (PSM) is idiopathic. Cervical trauma, ischemic myelopathy secondary to a spinal dural arteriovenous fistula, syringomyelia, Lyme neuroborreliosis, human immunodeficiency virus central nervous system infection, and cervical disc herniation can be the cause of PSM, but lumbar herniated intervertebral disc (HIVD) induced PSM has not been reported. We describe a...
