A functioning prosthetic arm, created by
Todd Kuiken, MD, at the
Rehabilitation Institute of Chicago, is being tested by 59-year-old Jesse Sullivan of Dayton, Tennessee, who lost both upper limbs after suffering electrical burns. Doctors connected residual nerves to healthy chest muscles and attached electrodes to his chest. The electrodes send signals to a computer in the 12-pound arm telling it how to move. The model is expected to be widely available in 2008.
