A paraplegic man who was paralysed for five years has walked again on his own two feet, thanks to a new kind of brain-computer interface that can reroute his thoughts to his legs, bypassing his spinal cord entirely.
The anonymous man, who experiences complete paralysis in both legs due to a severe spinal cord injury (SCI), is the first such patient to demonstrate that brain-controlled overground walking after paraplegia due to SCI is feasible.
“Even after years of paralysis, the brain can still generate robust brain waves that can be harnessed to enable basic walking,” one of the researchers, Zoran Nenadic from the University of California, Irvine in the US, said in a press release. “We showed that you can restore intuitive, brain-controlled walking after a complete spinal cord injury.”
