Table 1.
Pre-stimulation results of the repeated-measures analysis of variance (ANOVA) that assessed the potential difference (if any) of the labeled magnitude scale (LMS) test and the near-infrared spectroscopy (NIRS; VWrSO2%) data in all stimulation parameters [high frequency median nerve stimulation (MNS), low frequency MNS and placebo].
