“Robotic legs built by scientists and engineers at Massachusetts Institute of Technology (MIT) use electrodes and a computer to decode the contractions of leg muscles in an amputated leg to turn ‘phantom’ movements into real steps.

The amputee’s brain controls all the movements and allows them to walk normally without having to consciously focus on how to move their leg.

Data show people who use the bionic legs walk 41 per cent faster than those with traditional prosthetic legs, and at a speed equivalent to people with two intact limbs.”
