Lulish
It's on a show called "24 hour TV" where special guests (Arashi were regulars on this show for a while) helped people who had disabilities to reach their dreams, or overcome their handicap. On an Ohno segment, he helped a group of deaf teenagers to dance to one of their song. It's a really great thing they did. ^^ So the footage of the woman walking, was I suppose, one of the people that wanted to reach a goal and overcome her disabilites.
