Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Bifrontal electrode placement, with each electrode placed 5 cm above the outer angle of the orbit on a line parallel to the sagittal plane. Treatment was given with a square-wave, brief-pulse, constant-current device for stimulating a seizure lasting a minimum of 20 seconds going up to a maximum of 60 seconds. It was administred three times a week, until remission or completing twelve treatments.

Comparator / control treatment
Bitemporal electrode placement, with each electrode placed on the perpendicular line 3 cm above the midpoint of the line joining the external auditory meatus and the outer canthus of the eye. Treatment was given with a square-wave, brief-pulse, constant-current device for stimulating a seizure lasting a minimum of 20 seconds going up to a maximum of 60 seconds.
