From: Tapping into the human spinal locomotor centres with transspinal stimulation
Effects of transspinal stimulation on the amount of variability of (a) step length and (c) step width fluctuations, estimated by the standard deviation (SD). Effects of transspinal stimulation on the temporal structure of variability of (b) step length and (d) step width fluctuations, estimated by the fractal exponent α-DFA. Mean-mean display of α-DFA and SD values overprinted with their relative differences between transspinal stimulation and control walking. Dots show the intersection between mean values with simultaneous 95% confidences on the means. If a confidence interval crosses the diagonal line, the corresponding mean difference is non-significant. Diagonal line represents equality of means (SUB sub-threshold, SUP supra-threshold).
