Proprioception (the sense, communicated by the nervous system, of where your body parts are relative to each other) is essential for many, particularly bimanual, daily activities. Modern prosthetics lacks this sense, so it is often difficult to perform hand-eye coordination tasks with them, sometimes making upper extremity prosthetics more a nuisance than an aid.
A prosthetic which connects with amputee “muscle spindle” (proprioception sense organs) nerves to provide proprioception would provide more natural function. Towards creating that proprioceptive prosthetic, this project compares muscle spindle afferent output computational models, using experimental data, to find the most accurate model. Hopefully, that model could later be used to predict what voltages should be provided to which muscle spindle afferent nerves in a residual limb connected to a proprioceptive prosthetic.
