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.
