A man who was paralysed from the chest down after a knife attack in 2010 can now ride an adapted tricycle.
In 2014, surgeons in Poland announced they had reversed Darek Fidyka's paralysis using cells taken from his nose to repair his spinal cord.
The former fireman says he has noticed a gradual return of feeling and muscle control below his injury.
The surgical team are now launching a search for two more paralysed patients who they will try to help walk again.
