  1. Session 1 and Session 2 are the mean values. Difference are the difference in the mean value from session 1 to 2. ICC, SEM, LOA and SRD are intraclass correlation coefficient, standard error of measurement, limits of agreement and smallest real difference, respectively. Absolute reproducibility results are also given in percentages (e.g. SEM%) by dividing it with the grand mean for both sessions. aindicates the use of Wilcoxon signed-rank test. bindicates the use of paired t-test
