Figure 2. Temporal changes in Y-Balance Test score at different pressures. (A) Temporal changes of ANT; (B) Temporal changes of PM; (C) Temporal changes of PL - dir; (D) Temporal changes of COM. Note: Lowercase letters indicate significant differences between time points: a, vs. baseline (T0), P < 0.05; b, vs. T1, P < 0.05; c, vs. T2, P < 0.05; d, vs. T3, P < 0.05. Uppercase letters indicate significant differences between groups at the same time point: A, vs. MP group, P < 0.05; B, vs. HP group, P < 0.05. MP, medium-pressure; HP, high-pressure; CG, control group; ANT, anterior; PM, posteromedial; PL-dir, posterolateral; COM, composite score.
