Electrical stimulation offers hope for adults with spinal cord injuries to learn to walk again.
Rob Summers is standing up. Two feet on the ground, legs straight, hips squared. He has done it thousands of times before — out of bed in the morning to practice with his championship-winning collegiate baseball team, or up from the couch to get a snack.

Before he could get out of the way, the car threw him to the ground, and the driver fled what was a gruesome scene: Summers lay on the asphalt in a pool of blood, the victim of a hit-and-run that severed the connection between his brain and spinal cord and paralyzed him from the chest down.
