Table 5
Number of phase reversals for each bipolar contact, LL-SSEP component and stimulation side (ipsi- and contralateral).
No significant difference was found in the number of phase reversals between bipolar contacts according to the Wilcoxon signed-rank test (p = 0.157 for ((0 vs. 1) vs. (1 vs. 2)), p = 0.395 for ((1 vs. 2) vs. (2 vs. 3)), p = 1.0 for ((0 vs. 1) vs. (2 vs. 3))).
