Cyberdyne's robot suit HAL to keep people walking - YouTube
I saw this device featured on the Science Channel just a couple of weeks ago. A crippled girl could walk by using this whereas she would have been in a wheelchair without it. Not only does it allow people to walk who normally can't, it turns out to be therapeutic. A man whose spine was crushed in an accident was told he'd be bed-ridden for the rest of his life. Not only can he walk with this device, it has trained his body to relearn how to walk and he can even walk now without the device although slowly and haltingly but over time who knows how much more he'll improve and even walking like that beats spending the rest of your life in a wheelchair or bedridden. Imagine what it might be able to do for people with Parkinson's which killed my father and left him bedridden for the last months of his life. The Japanese have done fantastic things with robots. It's incredible.
