If the inner socket of a prosthetic leg doesn't conform to the contours of the user's leg stump, considerable pain and even skin ulcers may result. A new prosthesis should help keep that from ...

A surgery developed at MIT, called agonist-antagonist myoneural interface (AMI), connects muscle remnants from the shin and the calf to allow near-natural movement for those using an advanced ...

"Smart" prosthetic legs can help amputees achieve a natural walking gait, but it's done through robotic sensors and algorithms that drive the limb forward at predetermined rates. A better way would be ...

A robotic leg with motors that work like bike gears could let a wearer walk up stairs – which many people find impossible with unpowered prostheses. Most prostheses have no motors to actively assist ...

A commercial robotic leg could potentially benefit both higher- and lower-mobility amputees, University of Michigan roboticists have shown for the first time. The leg provided the largest gains when ...
