#### 2.2.5 Statistical Analysis  
The normality of the data distribution was assessed using the Kolmogorov-Smirnov test with the significance level set at \(\alpha=0.05\). The data were not normally distributed; therefore, nonparametric statistical methods were used. Medians and interquartile ranges were used as basic descriptive statistics. RSI, ALS, RLS, and LESS scores between pre- and post-intervention testing were compared using the [PERSON] matched-pairs test. Comparisons between groups (EG versus CG) were performed using the Mann-Whitney U test. Because four statistical tests (2\(\times\) Wilcoxon test, 2\(\times\) Mann-Whitney test) were performed for each score, the Bonferroni method was used to control Type 1 statistical error. The differences between groups were demonstrated using the Hodges-Lehmann estimate of the median differences (MD) with 95% confidence intervals [lower, upper]. The significance level for each of the four tests was set at \(\alpha_{\text{B}}=0.05/4=0.0125\). The effect size was calculated using [PERSON]'s r (r = z/\(\surd n\)), where the z-score is gathered via the test procedure of the Wilcoxon or Mann-Whitney test, with the sample size represented by \(n\)[50]. To determine the magnitude of the effect sizes of the data, the thresholds of 0.1, 0.3 and 0.5 for small, moderate, and large effects, respectively, were used [51]. Statistical analyses were undertaken on Microsoft Excel for Microsoft 365 Apps (version 2109, Microsoft Corp, Redmond, WA, USA) and RStudio version 1.1.463 with R version 4.0.5 (R Core Team, Vienna, Austria).
