postT-preT VAS Mann–Whitney U test (Bonferroni correction)

Z P value
bTENS-cTENS –2.375 0.018
bTENS-pTENS –2.685 0.007a
cTENS-pTENS –0.348 0.728

preT: before treatment, postT: after treatment, VAS: visual analogue scale, TENS: transcutaneous electrical nerve stimulation, bTENS: burst TENS, cTENS: conventional TENS, pTENS: placebo TENS.

aP values indicate a statistical significance at P < 0.0167, after Bonferonni adjustment.
