Table 3: Comparison measures of reliability for p-vectors for each acceleration direction (X=Vertical; Y=Medial-lateral; Z=Anterior-posterior; and Res = $\sqrt{x^2+y^2+z^2}$ ), including intraclass correlation coefficient (ICC_(A,1)), standard error of the measurement ( $sd\times \sqrt{(1-ICC)})$ ), and the reliability coefficient ( $\text{CR = SEM}\times \text{1}\text{.96}\sqrt{2}$ ).
