War hero's Ben Parkinson's pioneering brain treatment
Paratrooper Ben Parkinson was the most seriously injured British serviceman in Afghanistan to survive his wounds after losing both legs above the knee, breaking his back and sustaining brain injuries after a bomb explosion in 2006.
Doctors told the lance bombardier from Doncaster that he would never walk or talk again.
Eight years later, Ben has proved medical experts wrong and his recovery has been an inspiration to thousands who saw him carry the Olympic flame in the 2012 Torch Relay.
His mother Diane told BBC Inside Out that his recovery had been a "a miracle".
Ben has continued to defy medical opinion and is determined to improve his walking and talking with the help of a pioneering treatment.
Reporter Emma Glasbey followed him as he embarked on hyperbaric oxygen treatment for his brain injury at Castle Craig Hospital in Scotland.
He travelled to Scotland with his friend, Steven Thomas, a former Royal Marine, who is also having the oxygen treatment for a brain injury.
Doctors hope the treatment will repair soft tissue damage and stimulate previously damaged areas of the brain, helping to improve his speech, balance and memory.
Inside Out is broadcast on BBC One Yorkshire & Lincolnshire on Monday, 26 January at 19:30 GMT and nationwide on the iPlayer for 30 days thereafter.
