Rats paralyzed by spinal-cord injury can learn to control their hind limbs again if they are trained to walk in a rehabilitative device while their lower spine is electrically and chemically stimulated. A clinical trial using a similar system built for humans could begin in the next few years.

The rehabilitative procedure led to the creation of new neuronal connections between the movement-directing motor cortex of the brain and the lower spine, the researchers report in Science.
