  1. SPARC, spectral arc length (less negative values reflect smoother movements); SD, standard deviation; t, t-statistic of the independent samples t-test; df, degrees of freedom; P, probability value. Significant probability values after Holm-Bonferroni corrections are indicated in bold font (P < 0.05/Ns)
