The video shows 24 year old Patrick from Austria demonstrating the pure awesomeness of his artificial hand, and aslo shows a test of a prototype which will give him additional wrist movement. He lost the use of his left hand after being electrocuted at work, and has now become the first ever to voluntarily have his arm amputed for an artificial replacement. In effect, the patient controls the hand using the same brain signals that would have once powered similar movements in the real hand.
