Playing the Nintendo Wii Fit could improve balance and help avoid falls in seniors, researchers taking part in a new study suggest. The University of Aberdeen, Scotland and the UK’s National Health Service (NHS) have embarked on a four month study on people over 70 to observe any changes in balance after regular use of the Wii Fit. The video game, which offers such sports as virtual golf, tennis and tenpin bowling, relies on players mimicking the games’ physical actions, which are then played out on screen.
