Mind-controlled prosthetic arm moves individual fingers

from Today in PT

Physicians and biomedical engineers from Johns Hopkins University School of Medicine, Baltimore, report what they believe is the first successful effort to wiggle fingers individually and independently of each other using a mind-controlled artificial arm to control the movement. The proof-of-concept, described online in the Journal of Neural Engineering, represents a potential advance in technologies to restore refined hand function to those who have lost arms to injury or disease, researchers said in a news release. The young man on whom the experiment was performed was not missing an arm or hand, but he was outfitted with a device that essentially took advantage of a brain-mapping procedure to bypass control of his own arm and hand. more
