Understanding and Enhancing Human Health and Movement

The purpose of this research study is to better understand how people move, so investigators can develop improved ways to help individuals with lower-limb and/or trunk paralysis perform everyday activities such as sitting, reaching, pushing a wheelchair, transferring, standing, stepping, and maintaining balance. This study evaluates how activating stabilizing muscles, either with surface electrical stimulation or with an implanted neural stimulation device may change the way these daily activities are performed and potentially enhance functional independence. A key goal of this project is to collect information on the safety and effectiveness of an implanted neural stimulation system. The U.S. Food and Drug Administration (FDA) permits the limited investigational use of this implanted system for individuals with lower-limb and/or trunk paralysis resulting from neurological conditions.
