Humans can accurately sense the position, speed, and torque of their limbs, even with their eyes shut. This sense, known as proprioception, allows humans to precisely control their body movements.

Today’s conventional prosthetic limbs do not provide feedback to the nervous system. Because of this, people with amputated limbs cannot feel the position, speed, and torque of their prosthetic joints without looking at them, making it difficult to control their movement. In order to create a more complete prosthetic control experience, researchers at the Center for Extreme Bionics at the MIT Media Lab invented the agonist-antagonist myoneural interface (AMI). The AMI is a method to restore proprioception to persons with amputation.
