Optimizing Warfighter Performance with Neurally Integrated Robotic Lower Limb Prostheses

Abstract

Majority of limb loss incidents (~75%) among US Military Service members is in the lower limb. However,restoring sensorimotor function with advanced active prostheses that communicate directly with the intactnervous system falls far behind development of robotic prostheses for individuals with upper limb loss. Theobjective of this project is to develop and deploy a fully implantable, self-contained, neurally integratedbidirectional lower limb neuroprosthesis that can be readily incorporated into the body schema and utilizedwithout cumbersome external components. In this project, a total of six subjects (three with trans-tibial andthree with trans-femoral limb loss) will be enrolled. Electrical stimulation through nerve cuff electrodesdirectly excites the sensory nerves remaining in the residual limb while electromyography (EMG) signals fromintramuscular electrodes are interpreted to intuitively control the actions of advanced robotic lower limbprosthesis. We examine the impact of integrating sensory feedback with EMG-controlled robotic prostheses onbalance, gait, and performance during complex mobility tasks in laboratory and during use at home and incommunity.
