A small implant in the neck helped seven chronic stroke survivors regain arm strength and dexterity. What does this spinal cord stimulation, still in clinical trials, really promise? Years after a stroke, certain everyday actions remain out of reach. Grabbing a cup, opening a door or buttoning a shirt can become ongoing challenges. In the United States, a team of researchers has just demonstrated that a small implant placed in the neck could restore some of the lost abilities. In seven patients with chronic stroke, this technology immediately improved the strength and mobility of the affected arm.
