ClinConnect Summary

Sample size calculation: A sample size of 52 participants was determined for this study, accounting for a 20% dropout rate. The calculation was performed using G\*Power software (version 3.1.7), based on an effect size of 0.87. This value was derived from a previous study by Van den Steen et al. (21), which measured the difference in mean tongue pressure strength between training and control groups. With an effect size of 0.87, considered a large effect, a minimum of 44 participants was required to achieve 80% statistical power at a significance level of 0.05. Statistical analysis: IBM SPSS...
