At the Cleveland Clinic in Cleveland, Ohio, specialists bring many of the most cutting-edge designs of current bionic research out of the lab and into patient use. While there always exists barriers in upgrading the mechanics of current biotechnology, some of the most important work being done seeks to unlock mysteries surrounding the human body. Together with fellow colleagues in Canada, researchers at Cleveland Clinic may have solved one of the most elusive problems in advancing bionic prosthetics for patients.
Led by Paul Marasco, researchers at the Laboratory for Bionic Integration, a part of Cleveland Cinic's Lerner Research Institute, worked with a team led by John Sensinger of University of New Brunswick's Institute of Biomedical Engineering (as well as supporting experts in Alberta and Virgina), to crack the code of restoring kinesthesia- the innate sense of movement- to patients relying on bionic limbs. Although bionic limbs have made vast improvements in maneuverability and ease of use, they have always been limited to one sense: sight. In order to fulfill mundane tasks like picking up objects, patients must be able to see their prosthetic limbs in action so that they are accurately used.

Implications of this innovation are huge. "By restoring the intuitive feeling of limb movement — the sensation of opening and closing your hand — we are able to blur the lines between what the patients’ brains perceived as self versus machine,” says Marasco. This feat may allow similar breakthroughs that will further integrate machinery into a human being's biological system. Prosthetic limbs, as well as exoskeletons such as the Ekso which, since its 2012 introduction to the market, has been making strides in improvement, will more and more be greeted by a user's mind and body as one and the same.
