Bionic leg is controlled by brain power | Science, Technology, Internet |

Researchers at the Rehabilitation Institute of Chicago Center for Bionic Medicine have created a prosthetic leg that reads motor intentions from tiny muscle contractions. Compared with prosthetics that are not able to "read" the intent of their wearers, the programmed robotic leg reduced the kinds of errors that cause unnatural movements, discomfort and falls by as much as 44%.
