Abstract

As spinal cord injury (SCI) disrupts the communication between neural circuitry, electrical stimulation of the spinal cord may improve the rewiring and recovery of the affected pathways. Recent advancements in transcutaneous spinal cord stimulation (tSCS) have shown the potential for neurological enhancements in individuals living with SCI. In this study, we introduce the Reynolds Innovative Spinal Electrical Stimulation (RISES) technology, a person-tailored, task-specific stimulation system with real-time optimization capabilities enabled by its multi-data acquisition and closed-loop capabilities. We piloted the safety and feasibility of the RISES system by implementing the developed technology as part of a clinical trial intervention aimed to apply closed-loop tSCS during activity-based training. The successful use of RISES confirmed its safe and feasible closed-loop tSCS methods, resulting in measurable immediate improvements in proximal muscle activation and with no adverse physiological effects being observed in the preliminary data.
