Prosthetic Legs Controlled by Person's Own Neural System Bring Natural Gait

"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 to give people full control over the limb through their nervous system -- and that's just what an MIT research team says it's done.

An experimental surgical procedure combined with a cu...
