Median and Interquartile Range of lower extremity isometric strength performance during test and retest, p-values from Wilcoxon signed ranks test, and reliability indicated by the intraclass correlation coefficient (ICC) and 95% confidence interval (n=38) for the average of 3 trials and the first trial (N=38).
