MedGadget gurus are reporting an active ankle/foot Orthosis from MIT and Brown University. The novel robotic prosthesis provides not only a mechanical structure but also a powered joint to aid in the walking process and eliminate the unnatural gait of the typical amputee. The ankle utilizes multiple springs to capture and release energy along with a small electric motor for an extra boost. The robotic ankle is scheduled to be available mid-2008 from iWalk, Inc.
