Mean (±SD) afferent firing and perceptual threshold at the heel, arch, Met, and toes for each afferent class (FAI, FAII, SAI, SAII). There were no significant differences between FAI or FAII afferent firing (AFT) and perceptual threshold at any foot sole location. SAI AFTs were significantly higher than perceptual threshold at the toes (P = 0.011), and SAII AFTs were significantly higher than perceptual threshold at the arch and Met (P values <0.001).
