A 26 year old man who lost the use of his legs due to a spinal cord injury has regained the ability to walk using a system controlled by his brain waves, along with a harness to help support his body weight. Adam Fritz has used a wheelchair for five years after an accident in which the motorcycle he was riding collided with some furniture that had fallen off a lorry in front of him. As a result, he was paralyzed from the waist down.
