Healing Hurt Nerves

SERIOUS SPINAL-CORD injuries often cause permanent paralysis. But research at Purdue University suggests that electrical fields can repair the damage and restore bodily sensation. The Andara OFS puts these findings to use. Doctors attach an implantable battery pack, plus six electrical leads, above and below the injured area. The electrodes emit an oscillating, low-voltage current that creates an electrical field around the injury and jump-starts the growth of nerve cells. In clinical tests, the device enabled paralyzed patients to detect sensory stimuli like heat and pain, which could help prevent accidents and infections. The device might even lead to movement in the hands, arms and legs. Expect the FDA to approve the Andara OFS next year. cyberkinetics.com
