Gait training are standard ingredients of many rehabilitation protocols. The SilverFit Mile projects a movie on a screen so that the patient feels he is making a forest or city walk-- optionally even in the local area!
Training on a bike is very familiar to mot people. A screen on the (motorized) bike allows people to feel as if they are outside again. Mountain stretches and races are also included.
Exisiting commercial game consoles, such as the wii, are often used in elderly care. Unfortunately, many people are unable to perform at the required level. Although many of the exercises are not medically relevant, consoles can be valuable addition for those who can reach the acquired skill level.
