Electrical stimulus helps paralysed man walk again

Pioneering treatment involving hours of training in tandem with electrical stimulus has allowed a hit-and-run victim who was completely paralysed from the waist down to stand up unaided and take steps on a treadmill.
According to the Lancet medical journal, American Rob Summers, 25, is the first patient to benefit from the treatment, which has taken three decades to develop fully. Mr Summers admitted that the procedure has changed his life.
Scientists say that the treatment bypasses the brain and teaches the spinal cord to control limbs and body functions independently, with Mr Summers - normally confined to a wheelchair - able to voluntarily move his hips, knees, ankles and toes.
Professor Reggie Edgerton from the University of California in Los Angeles, a leading member of the 11-person team of researchers, said: “The neural networks in the lumbosacral spinal cord are capable of initiating full weight bearing and relatively co-ordinated stepping without any input from the brain. This is possible, in part, due to information that is sent back from the legs directly to the spinal cord.
