Benchtop testing neuromuscular electrical stimulation (NMES) output synchronized with a state change detected by the finite state machine (FSM) of the pediatric robotic exoskeleton; one simulated state change with aligned signals from the NMES and FSM shown for example. Normalized output = 1 indicates stance phase on the FSM and maximum voltage from the NMES
