Acute SCI 8 10.49 ± 9.23 1.88 ± 0.33 1.46 ± 0.26 0.96 ± 0.12 8.20 ± 0.79 1.45 ± 0.24
Chronic SCI 7 12.21 ± 2.87 2.11 ± 0.16 1.48 ± 0.21 1.03 ± 0.13 8.00 ± 0.38 1.21 ± 0.14
SCI + Step-Training 6 10.43 ± 5.84 2.02 ± 0.49 1.52 ± 0.27 0.94 ± 0.17 7.93 ± 0.59 1.34 ± 0.22

The motor threshold (MT, H2,18 = 2.175; P = 0.337, Kruskal-Wallis), the stimulation intensity to evoke a M-wave of maximal amplitude (Mmax; H2,18 = 0.440; P = 0.803, Kruskal-Wallis) and the M-wave latency (H2,18 = 1.521; P = 0.468, Kruskal-Wallis) were similar across groups. Similarly, the H-reflex threshold (F2,18 = 0.828; P = 0.453, One-way ANOVA), the stimulation intensity to evoke a H-reflex of maximal amplitude (Hmax; F2,18 = 2.437; P = 0.116, One-way ANOVA), and the H-reflex latency (F2,18 = 0.337; P = 0.718, One-way ANOVA) were not different between groups. Values are mean ± SD.
