NEW YORK (CNN) – A 25-year-old man left paralyzed from the waist down after being hit by a car is able to walk again.
A treatment developed by researchers at UCLA and the University of Louisville treats Rob Summers' spinal cord with mild doses of electricity, using a device generally used to treat chronic pain.
"To everyone's disbelief, I was able to stand independently the third day we turned it on, and it was incredible," Summers said. "At this point, for me, it had got me to focus on what these doctors and scientists had done for their life's work and for me to set my goals again, even higher."
Doctors suspect 10-15 percent of people with spinal cord injuries could benefit from the treatment.
