Three paralysed men, who were told they would spend the rest of their lives in a wheelchair, are able to walk again thanks to doctors in Switzerland.
“An electrical device inserted around the men’s spines boosted signals from their brains to their legs.
“And it also helped damaged nerves in the spinal cord to regrow.
“The researchers hope that this unexpected bonus will enable some paralysed people ultimately to regain independent movement.
“BBC News has had exclusive access to the patients in the clinical trial, the results of which are published in the journal Nature.
The first patient to be treated was 30-year-old Swiss man David M’zee, who suffered a severe spinal injury seven years ago in a sporting accident.”
