After losing his lower right leg in a motorcycle accident four-and-a-half years ago, 32-year-old Zac Vawter has been fitted with an artificial limb that uses neurosignals from his upper leg muscles to control the prosthetic knee and ankle. The motorized limb is the first thought-controlled bionic leg, scientists at the Rehabilitation Institute of Chicago reported Wednesday in The New England Journal of Medicine.
“This is a groundbreaking development,” says lead author Levi Hargrove, a biomedical engineer and research scientist at RIC. “It allows people to seamlessly transition between walking along level ground and going up and down stairs and slopes.”
Until now, only thought-controlled bionic arms have been available to amputees.
When Vawter thinks he wants to move his leg, the brain signal travels down his spinal cord and through peripheral nerves and is picked up by electrodes in the bionic leg...
Virtual Reality needs a controller? How about mind controlled?
