Functional neuromuscular stimulation (FNS) is a clinically proven method for helping people with spinal cord injury (SCI) stand again. To keep their balance, people with SCI mostly rely on upper-body effort on an assistive device. We investigated the development of a sensor-based control system that provided assistive balance capabilities while the participant performed reaching movements similar to those during activities of daily living. The control system included an FNS implant, wearable control unit, and only two small bodymounted sensors. With the control system active, the participant could perform reaching movements with 27% less upper-body effort.
