Doctors managed to return the sensitivity of the patient`s arm using a new type of prosthesis
10 years ago Nathan Copeland was in an accident, with the result that his motor functions were partially paralyzed. Now, thanks to a team of scientists from the University of Pittsburgh, Copeland, maybe the commands of the brain to control robotic arms and even feels the pressure from touching anything. Such a wonderful sensation gave him a new modification attached artificial hands instead of the lost.
It"s a real achievement, this is a serious breakthrough for the future of prosthetics. The goal was to create the communication stream, plus a computer brain interface that can be shared in both directions – from the brain to the arm and hand to the brain. This constant is important for a natural grip, because we always interact with objects of different weights and sizes. If you think about what to hold a pencil, but in fact you have the paper in hand, your movement will be incorrect, adjusted for weight and dimensions. In order for the interaction of brain and hand were adequate, should be aboutenergy the exchange of data in real time.
the feelings of the patient, who sewed neurosurgeons new hand.
"I can feel almost every finger – a really strange feeling," said Copeland, is a miracle of feelings came, after installing the system on the basis of electrodes that were previously implantion in his hand. "Sometimes there is a feeling, electrical breakdown, and sometimes pressure, but in most cases I can determine, all the finger with millimeter precision, as if my fingers can touch or slide on the surface of the object."
