Brainwave tech helps man to walk again
New technology has helped a man in America to walk again, five years after a motorcycle accident left him unable to use his legs.
The special tech uses sensors which can send signals from his brain to his knees to tell him to walk.
Scientists say it's the first time someone with his type of injuries has been able to walk again without relying on robotic legs.
