The pain analysis using the McGill Pain Questionnaire (MPQ) showed that for the PPI, PRI and NWC indices before the treatment, the means for groups 1 and 3 were different, but groups 1 and 3 were each the same as group 2 (P < 0.05). After the treatment, the means for groups 1 and 2 were different from the mean for group 3 but were the same as each other. The decrease in PPI was greater in group 1 (-1.45) and the decreases in PRI (-25.34) and NWC (8.29) were greater in group 2. These decreases in PPI, PRI and NWC were evaluated using Anova, which showed differences in the decrease between the groups: PPI (P < 0.01), PRI
