Table 1.
Mean (SD) values of absolute repositioning errors for the initial set of tests performed by all subjects (n = 40) on the first test day. Intraclass correlation coefficient (ICC) and standard error of measurement (SEM) values are based on repeated within-day (n = 21) and between-day (n = 19) measurements.
