Figure 5.

Box plots (median, IQR, minimal, and maximal values) illustrated absolute changes from baseline in the HRT variables in each real and sham MENS group. Real MENS significantly increased the number of plantar flexions. However, sham MENS significantly decreased the number of plantar flexions and the total time (seconds) for HRT. The median difference in the number of plantar flexions and the total time for HRT was significantly higher in the real MENS group than in the sham MENS group. Wilcoxon signed-ranks test was used for comparison between at baseline and after intervention data within each group and Student's t-test or Mann-Whitney U test was used for comparing the median differences between group. ^∗ = P < .05, ^∗∗ = P < .01, HRT = single leg heel rise test, IQR = interquartile range, MENS = microcurrent electrical neuromuscular stimulation.
