Paralysed men move again with spinal stimulation

They were able to flex their toes, ankles and knees - but could not walk independently, BBC News reports. A report, in the journal Brain, suggests the electricity makes the spinal cord more receptive to the few messages still arriving from the brain. Experts said it could become a treatment for spinal injury. The spinal cord acts like a high-speed rail line carrying electrical messages from the brain to the rest of the body. But if there is any damage to the track, then the message will not get through. People with spinal cord injuries can lose all movement and sensation below the injury. Zap A team at the University of Louisville and the University of California have been pioneering electrical stimulation of the spinal cord below the injury. Three years ago they reported that Rob Summers - a keen baseball player who was paralysed from the chest down in a hit-and-run car accident - was able to move his legs while supported on a treadmill. Now three more patients, who had been paralysed for at least two years, have gone through the procedure and regained some movement. They were able to control their legs at a precise pace and all but one of them were able to control the force of the movement. It confirms that function can be restored after paralysis and that Mr Summers' case was not a one-off. Full story
