Man walks again with aid of exoskeleton

Errol Samuels, a 22-year-old whose legs are paralyzed, is learning to walk again less than two years after an accident confined him to a wheelchair. Using a computer-controlled exoskeleton called "ReWalk," Samuels is walking on crutches during physiotheraphy sessions in New York City. It's designed to rehabilitate spinal cord injuries like Samuels to eventually walk again, without the aid of machines.
