Amputee Recovers Feeling with Robotic Arm

From the creator

The opening ceremony of the 2014 World Cup in São Paulo, Brazil, put under spotlights some very exciting technological innovations. To kick off the tournament, young paralysed people used an exoskeleton guided by their thoughts. This playlist is to recall you euronews' videos explaining how exoskeletons and human form robots can help people to move, live and feel better: European researchers have created a robotic hand that gave an amputee a sense of touch he had not felt in a decade. With the artificial limb, the patient could "feel" the different objects - such as a bottle, some cotton or a piece of fruit - and was able to intuitively adjust his grasp. Amputee Dennis Aabo Sorensen lost his left hand in a firework accident. "That was truly amazing to suddenly feel something after nine years," he said. "Because suddenly my hand is talking to the brain again, if you wish, and that was incredible." Doctors at Rome's Gemelli Hospital implanted tiny electrodes inside two nerves in the stump of Sorensen's arm. When the nerves were stimulated with a weak electrical signal, Sorensen said it felt like his missing fingers were moving, which meant the nerves still worked. The team put sensors on two fingers of a robotic hand, to detect information about what the artificial fingers touched. This information was sent to Sorensen's brain. "The electrodes are really selective, in the sense that they are able to achieve a very precise contact with small fascicles in the nerves.
