Multiaxis Prosthesis Control Through an Osseointegrated Neural Interface
Abstract
Persons with lower-limb amputation lose both the structure of a limb and control over its functions. This research will contribute to solving problems of prosthesis function, attachment, and sensorimotor interfacing. We will refine a two-axis prosthetic ankle to improve balance and reduce discomfort by adapting to terrain and different movement behaviors. We will test this prosthesis to determine its benefits in activities including sloped walking and walking on curved paths or turns. We will also advance the science of osseointegration and neural interfaces using sheep as a model of human amputation, implanting a mechanical anchor in the bone and a two-way neural recording and stimulation system with nerves in both muscle and bone. The mechanical anchor will support the prosthesis, whereas the neural interface will transfer neural signals from the sheep to control the prosthesis and from the prosthesis to give sensation to the sheep. We will test the ability of the sheep to control the prosthesis and to sense ground forces using this two-way neural interface.
