This table shows the results of algometry of the initial measurement prior to the first stimulation session and the last measurement subsequent to the last stimulation session. The mean PPTs out of the second and third measurements were calculated in each subject for each point, thus discarding the first measurements.
a
Wilcoxon singed-rank test (with Bonferroni correction for multiple testing; statistically significant p-values after correction for multiple testing are printed in bold, statistically significant p-values that did not survive correction for multiple testing are printed in italics).
b
Friedman test.
c
Nemenyi post-hoc test.
