Fig. 2 Correlation scatterplots for pretreatment in stage 1: (A) pain threshold correlated positively with pain tolerance (R =.830, P<.01; y =1.20x +0.48), (B) VAS correlated negatively with pain threshold (R =−.250, P<.05; y =−.40x+6.75); and (C) VAS correlated negatively with pain tolerance (R =−.305, P<.01; y =−.33x).

Fig. 3 Correlation scatterplots for posttreatment in stage 1: (A) pain threshold correlated positively with pain tolerance (R =.802, P<.01; y =1.04x +0.96); (B) VAS correlated negatively with pain threshold (R =−.314, P<.01; y =−.38x+5.39); and (C) VAS is negatively correlated with pain tolerance (R =−.280, P<.01; y =−.29x +5.35).
