Persistence of pain pathway activation and rate-dependent enhancement of pain for individuals with and without SCI. Nerve stimulation conditions are color-coded: magenta for superficial peroneal nerve (SPn) stimulation, green for sural nerve (SRn) stimulation, and brown for distal tibial nerve (DTn) stimulation. For each nerve stimulated, the data for 4 s inter stimulus train intervals (ITIs), 1 s ITIs , and the difference between 4 s ΔI and 1 s ΔI (Diff.) are shown for individuals with (filled bars) and without SCI (open bars). Each x symbol represents an individual’s value. For a given nerve stimulation condition, the number of participants included in comparison is indicated in the right most set of bars.
