A-C, control (thin lines) and conditioned EMGs (thick lines, 50 trials of each), expressed in mV, are plotted against the latency (ms) in relation to the conditioning stimulations applied to the CPN adjusted at 2.5 × MT (A), to the skin where stimulating electrodes were 5 cm more distal than those of the CPN (B), and to the cutaneous branch of the SPN where stimulating electrodes were 32 cm more distal than those of the CPN (C). The intensity of the cutaneous stimuli was adjusted so as to imitate the cutaneous sensation produced by the mixed nerve stimulation.
