The pre-test was performed before the intervention, and the post-test was performed after 12 weeks. The Mann–Whitney U test was performed for MAS. Significantly differences were found *within groups and †between groups. ‡in the pre-test comparisons between the intervention and control groups, a significant difference was observed (p<0.05). The significance level was set at p<0.05 for differences between the two groups.

The model includes data from 186 observations across 93 participants during each period. The intercept represents the predicted FMA_total score for a non-intervention individual at baseline FMA_total of zero. Each coefficient is presented with its respective standard error, z-value, p-value, and 95% confidence interval. The variable 'Intervention' indicates the group, and 'Periods' distinguishes between pre- and post-intervention assessments. 'Baseline' denotes FMA_total score at baseline. Statistical significance is set at *p<0.05. SD; Standard Error, β; estimated coefficient |

This table presents the results of a Mann–Whitney U test comparing the changes (Δ values) in FMA scores before and after treatment between the control and intervention groups. Δ values are calculated as the difference between post- and pre-intervention scores for each measure. The table includes the median changes along with the first and third quartiles for each group. *P-values <0.05 indicate statistically significant differences between the groups. Effect size (r) is reported to quantify the magnitude of the difference, with values closer to -1 or 1 indicating a stronger effect. Scores are presented as the mean, 95% CI. |

A Mann–Whitney U test was used to compare changes in MAS and ROM between groups, quantified by calculating the difference (Δ values) between pre- and post-intervention measurements. P-values are presented for the results of comparisons between the shaking exercise and control groups. *p<0.05 for within-group comparisons were performed using a Wilcoxon signed-rank test. Data are presented as medians and 25th–75th percentile values. |

The pre-test was performed before the intervention, and the post-test was performed after 12 weeks. The Mann–Whitney U test was performed for MAS. Significantly differences were found *within groups and †between groups. ‡in the pre-test comparisons between the intervention and control groups, a significant difference was observed (p<0.05). The significance level was set at p<0.05 for differences between the two groups.

The model includes data from 186 observations across 93 participants during each period. The intercept represents the predicted FMA_total score for a non-intervention individual at baseline FMA_total of zero. Each coefficient is presented with its respective standard error, z-value, p-value, and 95% confidence interval. The variable 'Intervention' indicates the group, and 'Periods' distinguishes between pre- and post-intervention assessments. 'Baseline' denotes FMA_total score at baseline.

This table presents the results of a Mann–Whitney U test comparing the changes (Δ values) in FMA scores before and after treatment between the control and intervention groups. Δ values are calculated as the difference between post- and pre-intervention scores for each measure. The table includes the median changes along with the first and third quartiles for each group. *P-values <0.05 indicate statistically significant differences between the groups. Effect size (r) is reported to quantify the magnitude of the difference, with values closer to -1 or 1 indicating a stronger effect. Scores are presented as the mean, 95% CI. |

A Mann–Whitney U test was used to compare changes in MAS and ROM between groups, quantified by calculating the difference (Δ values) between pre- and post-intervention measurements. P-values are presented for the results of comparisons between the shaking exercise and control groups. *p<0.05 for within-group comparisons were performed using a Wilcoxon signed-rank test. Data are presented as medians and 25th–75th percentile values. |
