The changes in the cerebrospinal fluid (CSF) suggested a viral infection. Clinical and electrophysiological findings indicated that the involuntary movements were arising at spinal level and were independent of suprasegmental influences. There are few previously ...
متن کاملPropriospinal myoclonus in multiple sclerosis.
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 varia...
متن کاملReflex myoclonus in olivopontocerebellar atrophy.
The presence of reflex myoclonus in response to touching and pin-pricking the wrist or stretching the fingers and to photic stimulation was assessed in 24 patients with a presumed diagnosis of olivopontocerebellar atrophy (OPCA) and in 30 age matched control subjects. Reflex myoclonus to soma-esthetic stimulation was found in 23 patients and in none of the controls. Photic myoclonus was present...
