A great step forward in the design of prosthesis, lets hope it doesn’t cost an arm and a leg! – Deskarati
A bionic prosthetic arm that is controlled by its operator’s thoughts and feels like the amputee’s lost limb went on display at a major U.S. science conference.
The arm uses technology called Targeted Muscle Reinervation (TMR), which works by rerouting brain signals from nerves that were severed in the injury to muscles that are working and intact. “What we do is use the nerves that are still left,” Kuiken said. “Muscle becomes the biological amplifier.”
Glen Lehman, a retired U.S. military sergeant who lost his arm in Iraq, demonstrated the latest technology at the annual conference of the American Association for the Advancement of Science in Washington.
“It feels great, if feels intuitive. It is a lot better than the other prosthetic I have now,” said Lehman, whose forearm and elbow were blown off in a Baghdad grenade attack in 2008.
“The other one is still controlled by muscle impulse, you just flex muscle to make it move, it is not intuitive. This arm is more trained to me, whereas the other arm I had to train to it,” he said. “It does feel like my own hand.”
