Swiss scientists are developing neuroprosthetic technologies designed to restore voluntary locomotion control to patients with severe spinal cord injuries. Grégoire Courtine, of the École Polytechnique Fédérale de Lausanne, expects to begin clinical human trials within the next two years. He detailed his study, which used a robotic harness and electrochemical stimulation to restore movement in paralyzed rats, and described what's ahead at a recent scientific meeting in Boston.
