Complexity-based and Traditional measures of sway for the Randomized to Tai-Chi and Randomized to usual care groups across visits.

avalues provided are mean ± standard deviation. bvalues are estimated slope (lower 95% confidence interval, upper 95% confidence interval). cp-values for testing for an effect of age indicated by p-age. dp-values for comparing mean rates of change among Tai-Chi vs. usual care groups indicated by p-group*time.Complexity-based and Traditional measures of sway for the Randomized to Tai-Chi and Randomized to usual care groups across visits.
