Bland and Altman graphs for left ankle location for 8 participants in perturbation during walking in (a) the z-axis/anterior-posterior displacement; (c) the y-axis/vertical displacement; and (e) the x-axis /mediolateral displacement, and during standing in: (b) the z-axis/anterior-posterior displacement; (d) the y-axis/vertical displacement; and (f) the x-axis/mediolateral displacement. The difference (anterior-posterior, vertical and mediolateral displacements) between the motion analysis (APAS Inc.) vs. Microsoft Kinect systems is plotted against the mean for each subject. Mean difference between the two tests: solid line; 95% confidence interval of the mean difference: dotted line (95% CI); limits of agreement: dashed line (LOA)
