Is There a Spontaneous Cause of Spinal Cord Injury?

CNN's John Defterios takes a closer look at the technology being developed to help people with spinal cord injuries walk again. He asks questions that can be taken out of context, such as: Did they have an experience of feeling nonow when it was stimulated? And if so, what kind of feedback did he get back from his test subjects? Do you think this could work for someone who has been diagnosed with spasticity in their legs and is unable to move them on their own? If yes, we would like to see more research into whether or not there are any practical uses for these kinds of prosthetic limbs.
