Values are presented as mean ± standard deviation (SD). Mean difference, 95% confidence interval (CI), t-value, degrees of freedom (df), and p-value are shown. Effect size is calculated as Cohen’s d (small ≥ 0.2, medium ≥ 0.5, large ≥ 0.8). AS: Ankle sprain group; non-AS: non-ankle sprain group., DF; dorsiflexion, PF; plantarflexion, º; degree *; p ≤ 0.05.
