Stimulation parameter scatter plot. a Frequency vs. stimulation intensity. b Pulse width vs. stimulation intensity. Red dots represent studies using electrical stimulation of afferent pathways. Yellow dots represent studies using FES. Studies testing multiple stimulation parameters are represented by multiple dots. Studies performed by the same research group or replicating the same conditions are represented by the same dot. Note that four studies used stimulation of afferent pathways with stimulation intensity above motor threshold. ***Not described in paper
