Abstract
|
|
|
|
Radicular myoclonus (RM) is a kind of peripheral myoclonus exclusively related with traumatic spinal root lesion. Here we describe a case with involuntary scapular movements as a possible manifestation of RM. A 37-year-old woman without any underlying disease developedinvoluntary movements of left shoulder two days after cervical trauma. On needle electromyographic recordings, the myoclonic jerky movements were found in left serratus anterior and rhomboid major muscles, and the duration of bursts ranged from 100 to 300 ms with the irregular frequency of 1?2 Hz. Electromyography studies showed accompanying left C5 radiculopathy. Treatment with clonazepm markedly improved involuntary scapular movements.
