2.5. Statistical Analysis
Patients’ height, weight, BMI, SMI, and tongue pressure were measured before and after treatment. Two parameters, the CoV and RMS, were calculated using the HD-sEMG. The Wilcoxon signed-rank test was used to compare the results before and after each treatment. The rate of change (measured value before start–measured value after treat-ment/measured value before start × 100) was calculated. The CoV and RMS were measured before and after treatment, and the rate of change before and after treatment was calculated. Correlation coefficients were calculated for each of the three physical assessment items and the two parameters of the HD-sEMG. Statistical analyses were performed using JMP Pro ver.16.2.0 (SAS Institute Inc., Cary, NC, USA). The threshold for statistical significance was set at
