Comparing the number of zero-crossings (N_k), and the standard deviation of the time between zero-crossings (σ_k (milliseconds)), of the first eight principal accelerations (PA_1–8) between the dominant (DO) and non-dominant (ND) legs (mean ± SD; * significance with Holm–Bonferroni correction, at p < 0.006; p-values smaller than 0.05 are printed bold).
