Intrasession intraclass correlation coefficients (ICC). The ICCs and its 95% confidence interval are presented for the first two trials, the first five trials and the last five trials out of ten in healthy subjects (n = 20) and for the last five trials in subjects with SIS (n = 30). The ICC are only presented for the last five trials in the SIS groups since the ICC were similar for the subjects with and without SIS. * Significant differences (P < 0.05) between the first two trials and the last five trials for healthy subjects.
