From the Winston-Salem journal - a report on a study into the use of the Wii in a retirement home.

Interestingly the study is more concerned with the socialising aspect and psychological effects of such games, rather than just the physical benefits of the activities. I think this is an aspect that is too easily forgotten about when people talk about active or fitness games. There is often an over-concentration on the mechanical side of exercises or activities which neglects the effect that socialising, enjoyment, and motivation can play in both physical and mental well-being.

I often hear people complain that Wii Fit is nothing compared to pounding away at the gym, while missing the fact that if people enjoyed the gym, we wouldn't have the obesity problems we have now. A activity may not be the optimum method of training, or keeping someone who is ill or elderly active, but if it motivates them into doing something, it is infinitely preferable to the unenjoyable but more "correct" exercise that might be prescribed by text-books. As I think many therapists are well aware, something is generally better than nothing.
