Stroke is a leading cause of death and the most common cause of long-term adult disability in the United States. Nearly three-quarters of people worldwide who suffer a stroke will have lasting loss of arm and hand movement. This loss of motor control can greatly hinder everyday activities. There are no effective treatments for chronic paralysis that lingers beyond six months after stroke.
Over the past decade, several NIH-supported studies have reported success in using a technique called spinal cord stimulation to improve limb movement in people after spinal cord injury. The approach involves surgically implanting thin metal electrodes onto the surface of the spinal cord and then delivering electrical impulses. The impulses are designed to amplify weakened nerve pathways that control movement.
