Older Australians in four aged care homes in NSW and Victoria will this month trial a new exercise program based on arcade-style dance games.

Players can navigate the games by stepping on a wireless mat linked to a TV that displays game cues.

The quicker and more precise their steps are, the more likely users are to progress through the game.

It's hoped the program will improve the balance of older people, reducing their risk of falling by up to 50 per cent and prevent or slow the onset of dementia.

If successful, the smart+-step program designed by Neuroscience Research Australia will be rolled out to 3000 older Australians in residential homes across the country.

"To make this type of exercise more enjoyable and motivating, we have taken the fun elements of a game and converted them into a program that will improve someone's balance and thinking skills," the program's designer Daina Sturnieks said.

Glen Hurley, chief operating officer of Allity aged care homes where the program will be trialled, says the game also has some positive side effects.

"In addition to boosting fitness and cognitive health, smart+-step gives our residents a small dose of healthy competition, and we can already see how it is improving their sociability," he said.

"The program is having an immediate effect on boosting morale and the motivation to be active and healthy."
