Brain-driven prosthesis marks scientific advance for people with amputations
It’s a scientific advance that allows for a smoother gait and enhanced ability to navigate obstacles.
“This is the first prosthetic study in history that shows a leg prosthesis under full neural modulation, where a biomimetic gait emerges. No one has been able to show this level of brain control that produces a natural gait, where the human’s nervous system is controlling the movement, not a robotic control algorithm,” says Hugh Herr, a professor of media arts and sciences, co-director of the K. Lisa Yang Center for Bionics at MIT.
