Abstract
Electrical stimulation of the spinal cord can be used for treatment of intractable pain and spasticity. Based on our experimental findings cervical spinal cord stimulation (cSCS) was performed on eight patients with severe brain dysfunction due to traffic accidents, pronounced vasospasm caused by subarachnoid hemorrhage or surgery of huge cerebral tumors (chordoma). After a 1 to 2 month period of stimulation, two patients became conscious and began to speak. It remains unclear whether cSCS induced the restoration of consciousness and improved neurological deficits. Although the successful results might be due to chance, cSCS might have stimulated brain function. This preliminary report shows such excellent results that further studies are warranted.
