  1. SD Standard Deviation; ICC Intraclass Correlation Coefficient; CI Confidence Interval. SEM Standard Error of Measurement; MDC Minimal Detectable Change. P-values in bold indicate statistical significance of the Wilcoxon signed-rank test (P lower than 0.05). † Negative values: flexor muscles tone. Positive values: extensor muscles tone
