Robotic suits and spinal zaps help paralyzed veterans take steps

This small pilot study tested two ways to stimulate the spinal cord—one with a surgically implanted device and one with surface electrodes—combined with a robotic exoskeleton to help people with spinal cord injury walk. Four men with complete paralysis below the chest took part. The goal was to see if these methods could improve walking speed and muscle activity, and possibly reduce other health problems linked to inactivity.
