Semiology characteristics and location of epileptogenic zone in motor seizures of axial and shoulder girdle muscles assessed by video-stereoelectroencephalography study in 65 patients.

The incidence of ASMs is high in insular and perisylvian. Unilateral cervical tonic seizures have good lateralizing value. Based-on semiology characteristics, ASMs can be roughly clustered into two categories, which can only effectively distinguish the origins of temporal lobe and posterior cortex, with low discrimination for the seizure-onset of other lobes.
