Sensitivity analysis using ANCOVA, after controlling for the influence of baseline pre-treatment FMA-LE scores (covariate p = 0.686), found that the differences in improvement values among frequency groups remained highly significant ( F = 100.634, p < 0.001).

However, the overall comparison of post-treatment level distribution across the three groups did not reach statistical significance (Kruskal-Wallis H test, χ 2 = 5.167, p = 0.076).

Exploratory post-hoc comparisons suggested that the improvement in the medium-frequency group was greater than that in the high-frequency group ( p = 0.019) and showed a trend towards being better than the low-frequency group ( p = 0.100).

Ankle dorsi-flexor strength improvement was significantly greater in the medium-frequency group (1.93 ± 0.25 grade) compared to both low (0.97 ± 0.18 grade) and high-frequency groups (1.03 ± 0.18 grade) ( p < 0.001), with a favorable trend also observed in FAC.
