Mind-controlled prosthetic arm enables patients to feel the objects they grip
When electrician Rickard Normark lost his left arm after being electrocuted at work in 2011, he thought he had no other option than to endure the pain and discomfort of a conventional prosthesis. It would often slip off during his daily activities, and he scratched the irritated skin under the socket so much with his healthy hand that it began to lose sensation.
Then three years ago, Normark received a new kind of brain-controlled prosthetic that was surgically attached to the bone, muscles, and nerves of his upper arm, allowing him to not only grip objects intuitively with his hand but feel the sensation of touching them.
