TABLE 2A.

Mean, standard deviation (SD), mean difference and standard deviation of differences, Bland–Altman limits of agreement (LOA) over a 95% confidence interval (CI), intraclass correlation coefficient (ICC) values, lower bounds and upper bounds of agreement [ICC_(2,1)] and consistency [ICC_(3,1)] for the comparison of spatiotemporal measures extracted by the pressure-sensitive walkway (PSW) and markerless motion capture (MLMC) for the self-selected (SS) walking speed task.
