95% Conf MLSway = 95% confidence mediolateral sway, 95% Conf AP Sway = 95% confidence antero-posterior sway, 95% Conf Max Sway = the 95% confidence maximum sway (the largest sway in any direction), Average Sway Vel = average sway velocity (calculated as the sway path length (how much the CoP moved during the test) divided by the duration of the test), 95% Conf Ellipse Area = area of the 95% confidence ellipse.
In bold the results that are statistically significant, their partial η2 and observed power In underlined italic the results that got worse after treatment mCTSIB = all 4 posturography tests combined as repeated measures. In bold the results that are statistically significant. In underlined italic the results that are worse POST vs. PRE mCTSIB.
