When electrodes were implanted in the spinal cord of a patient with MS--for dorsal column stimulation to relieve intractable pain--she regained considerable movement in her legs. Subsequently such stimulation has been employed in more than 70 other patients, and many have regained voluntary control over their arms, legs, and sphincters. The procedure is detailed and its implications are explored.
