A spinal injury can lead to paralyzing the limbs and other body parts. This sort of injury breaks the connection of the nerves running through he spine. A new innovative device was implanted to four paralyzed men to restore this break. The results are very promising. The device "reads" the incoming electrical signals from the brain through the spine and then re-transmits the signals under the damaged part. Some managed to move their limbs again. With physiotherapy the results showed that less stimulation was needed suggesting that the broken nerve connections learn to read the signals better.
