While no one is suggesting that Wii-hab will provide miracle cures, or reduce the need to develop new drugs, Ben Herz believes it is a “no-brainer” that its potential should be tapped more — and not just for Parkinson’s disease.

“It promotes functional movement,” he says. “There are off-the-shelf cooking games and surgery games as well as sports games, so there are all sorts of movements you’re practising. Even people who are in nursing homes can play them lying down.”
