There is currently no cure for upper limb paralysis, where there has been damage to the nerves which send messages to the muscles from the brain, such as happens after a stroke or spinal injury.
However, researchers at Newcastle University have been able to demonstrate the re-animation of a monkey’s paralysed hand for the first time by stimulating the spinal cord.
By using electronic stimulation, they have been able to make the brain’s impulses reach a paralysed hand and perform a desired action, such as a grasping motion.
Using this latest research, scientists hope to produce an implant within five years, which could cure paralysis for stroke sufferers.
