Undergraduate Research Posters 2012
Traditional, passive leg prostheses for transfemoral amputees require the user to produce unnaturally large actuations in order to walk. The resulting motions can cause joint degeneration and arthritis. To avoid this, a semi-active prosthetic knee using hydraulics to store and release energy has been developed. In our work this summer, we have improved upon a previous simulation model for this leg, and we have developed preliminary valve control results in this simulation software with BBO.

Two areas of research interest in the design and use of lower limb prosthetic devices are how foot performance varies with design and how prosthesis alignment affects gait. The current study addressed both of these areas through the use of the JR3 triaxial transducer mounted at the base of the socket. The transducer is an innovative form of instrumentation that measures forces and moments at the end of the socket. Traditional measurement of gait uses a force plate buried in the floor of a gait laboratory. The study established that the transducer offers a viable means of instrumentation for amputee …

The following is an excerpt from the introduction of this paper: Imagine living a life where even the simplest of tasks such as eating a grape or holding an egg required intense concentration and months of training. Until recently, this was the harsh reality for people with upper limb prostheses. Currently, the most common upper limb prosthetic technology being used is body powered. These devices capture remaining shoulder movements with a harness and transfer this movement through a cable to operate the hand, wrist, or elbow. With this control method, only one joint can be operated at a time. When …
