Paralysed man moves arm after medical breakthrough
Radical new technology has allowed a paralysed man to use his arm again, giving hope to quadriplegics. Bill Kochevar, who was left paralysed below the neck after a cycling accident, can now drink a cup of coffee and eat using a fork. A device translates his brainwaves into electrical pulses which are sent to electrodes in his arm. As the electrodes are triggered, they cause movement in his paralysed muscles, allowing him to grasp his hand and raise his arm.
