Scientists Use Electrical Impulses to Help Paralyzed Rats Walk Again

Even after he lost the use of his limbs, Christopher Reeve believed in keeping fit. All the scientists working on cures to paralysis had warned him “it won’t do you any good if you don’t keep your body in shape,” he said. The millions who now suffer (about 1 in 50 Americans has some paralysis, according to the Christopher and Dana Reeve Foundation) would do well to heed his advice—for they are closer to being able to walk again.
