Leaping over spinal cord injury, researchers teach a quadriplegic's hand to move again

In a development that could help restore fine motor movement to patients with brain or spinal-cord injuries, researchers have briefly restored a 24-year-old quadriplegic man's ability to grasp a cup and perform other everyday tasks with his hand, wrist and fingers.

The effort, reported Wednesday in the journal Nature, set out to circumvent a spinal cord injury and reanimate a limb directly, using reinterpreted electrical signals issued by a patient's own brain.

In a lab in Ohio, those signals — recorded by a suite of sensors sunk into the subject's motor cortex — were painstakingly translated into electrical impulses that would command the young man's...
