Abstract

"Segmental myoclonus can be seen in variable lesions of the brainstem or spinal cord, but the pathophysiology of the segmental myoclonus is not fully defined yet. We describe three patients with delayed developed and chronically persisted involuntary movement restricted to one arm after mild cervical injury. Myoclonus developed 1 month later in 2 patients and the other 5 months later after the injury. They suffered from myoclonus for more than 2 months, 1 year, and 25 years, respectively. Clonazepam and phenytoin were tried, but not satisfactory.Key Words: Chronic segmental myoclonus, Cervical injury"
