Parkinson's implant restores man's walk

A man with advanced Parkinson's has been helped to walk again with a special implant that stimulates nerves in his spine.

Marc, 63 and from Bordeaux, is the first person in the world to try out the device and says it has given him a second chance in life.

He can now walk for miles, when previously he was often housebound and had several falls a day.

The medical team treating him describe the advance in Nature Medicine journal.

Watch how he walks with the stimulator working versus how he walks without its help.
