Three patients go hand amputated for prosthesis
A breakthrough in science: three Austrians got an artificial hand by signals are driven from their brain. The three have their cripple showed, unusable hand amputated and now can better function independently.
recently three patients with artificial hands that can be controlled by the brain at the University of Vienna. By using a new technique – called bionic reconstruction – the prostheses respond to stimuli from the brains, according to a publication in the scientific journal The Lancet
High expectations
. > This procedure can help you in the future to a large group of patients with cripple or severed limbs, such as victims of an accident with potato digger or bread slicer. Not only hands but also feet and legs would eventually function as weather is expected.
Two of the operated Austrians were injured while mountain climbing in their country, crashed in a motorcycle accident. But all three of them were serious, permanent injuries to their misfortune: the nerves from the neck to the hand tore off. A serious injury that prevents too much in contact sports such as rugby and American Football. The result: a – partially – cripple hand
Neurosurgeons knew the three men after an extensive study to convince them that they would be better off if they would have to amputate their unusable hand..
Transplantation
they then received a transplant from a piece of thigh muscle to the forearm stump. This muscle was coupled to the damaged nerve in order to establish the signal transmission between brain and prosthesis. The so-called robohand is pushed over the edge.
The three patients all received intensive cognitive training and exercised an average of 9 months with the robohand before they underwent their operations. This to activate the muscles and the use of electrical signals for controlling a virtual hand.
Profijt
The men who were hampered by their injuries in their daily functioning, had directly benefited from the robohand. Now they can perform a few simple tasks, such as lifting coins or a glass, crank up a can or pot, stir into pan and tying the laces of their shoes. In their recent publication in The Lancet let the scientists of the Austrian university in Vienna know that eventually technology will be deployed worldwide.
