'Stable' Error in a Powered Prosthetic Device (video) North Carolina State University Share Print E-Mail Loading video... Caption Powered lower limb prosthetics hold promise for improving the mobility of amputees, but errors in the technology may also cause some users to stumble or fall. New research from the lab of Helen Huang examines exactly what happens when these technologies fail, with the goal of developing a new generation of more robust powered prostheses. This video shows a "stable" error, where the user doesn't notice something went wrong. Huang is an associate professor in the joint biomedical engineering program at North Carolina State University and the University of North Carolina at Chapel Hill.
