Zap to unclench: electrical glove aims to restore grasp after stroke

This study tested a special device that uses gentle electrical pulses to stimulate paralyzed hand muscles in people who have had a stroke. The goal was to see if this 'neuroprosthesis' could help participants perform basic tasks like picking up a glass or a spoon, which they could not do on their own. Eleven stroke survivors with chronic hand paralysis tried the device during short, controlled tests to measure any improvement in their grasping ability.
