Values are presented as mean±standard deviation.

LAS: lateral ankle sprain, CAI: chronic ankle instability.

Effect size was calculated as eta square for Kruskal-Wallis H (η2H) and as partial eta square (η2p) for one-way analysis of variance (ANOVA). Statistical values were presented as H through Kruskal-Wallis H. §Statistical values were presented as F through one-way ANOVA.
