Note: in the table are reported the Pearson product moment correlation (Correlation), the Standard Error of the Measure (SEM), The Percentage SEM (SEM 8%) and the Effect Size (Cohen's d) computed from the standard deviation of the difference between signals over the standard deviation of the video signal. Percentage of bias, imprecision (standard deviation of the bias), upper (LoA+) - lower (LoA-) limits of agreement, Z-score value for each speeds (1 to 13 km · h−1), mean of walking (1 to 6 km · h−1), running (10 to 13 km · h−1) and overall mean of speeds (Locomotion).
