Brain-computer interface restores walking after paraplegia

Using an electroencephalogram (EEG) based system, the ability to walk has been restored following a spinal cord injury. The preliminary proof-of-concept study shows that it is possible to use direct brain control to get a person’s legs to walk again. The participant, who had been paralyzed for five years, walked along a 3.66m long course using a system that takes electrical signals from his brain, which then travel down to electrodes placed around his knees to create movement.
