Correlation analyses between the ratings combining both groups showed a significant association between the stimulation intensity and the rating of intensity perceived at the stimulation site [rho = 0.62, p < 0.005] as well as between the rating of intensity perceived at the stimulation site and the unpleasantness of stimulation at the stimulated site [rho = 0.75, p = 0.0005], and a statistical trend (p < 0.06) for an association between the stimulation intensity and the mean perception threshold.
