The 25-year-old from Johannesburg became the first double leg amputee to compete in athletics at the Olympics, reaching the 400 metres semi-final, before winning two gold medals and a silver at the Paralympics a month later.

Pistorius, who appeared alongside US actor Tyler Perry and the music band Plain White T's, discussed the Games with Leno, claiming that it was his team that had helped him make both the Olympic and Paralympic Games in top condition.

"When you get to the top of competition, you realise it is the whole team around you that gets you to that position," he said.

"It is not just you.

"I've got a phenomenal team behind me and it is great.

"I needed all their support because London 2012 was so crazy.

"You walk out into that stadium and you can hear a wall of noise.

"You try and stay calm but it is so loud; it was just amazing."

The appearance comes just days after Pistorius appeared with Ryder Cup hero and vice-captain Paul McGinley at the Dunhill Links golf Championships in Scotland.

He will be remaining in the US for the rest of the week, where his next appearance will be on the Piers Morgan Tonight show on CNN on October 12, followed by the Larry King Now show on HULU.com, to be broadcast at a later date.
