A priori power calculations G*Power was used to calculate the sample size required for 95% power.
The data came from an initial study, used to ensure the placement of the Kinect camera was correct.

The normality of the difference between the two methods given by D’Agostio-Pearson and Shapiro-Wilk tests for normality.
Table 4.
Repeatability of each method, Balance Master (BM) and the Proposed Pipeline (PP), has measured by the Standard Deviation (SD) and Repeatability Coefficient (CR).
Fig 5.
Bland-Altman plot of Balance Master vs the Proposed Pipeline’s estimates of postural sway.
Bold horizontal line indicates the mean, dashed horizontal lines indicate two standard deviations from the mean. The shaded areas represent associated confidence intervals. The figures marked a-f represent the six conditions of the SOT test.
Table 5.
A summary of the agreement of postural sway derived from the two methods: Balance Master (BM) and the Proposed Pipeline (PP).
The mean—within each method, mean—between the methods (bias), the 95% Confidence Interval (CI) and Limits of Agreement (LOA) and the significance of the t-test are shown.
