Values are in mean ± SD or F-value (p value). Pre: preassessment; Post: postassessment; FU: follow-up assessment; CS: composite score on the auditory Stroop test; CoP-AP: normalized CoP sway in the anteroposterior direction; CoP-ML: normalized CoP sway in the mediolateral direction; VCoP: average CoP sway velocity. Statistical significant interaction (); statistical significant difference between the Tai Chi and conventional exercise groups in the follow-up assessment (); statistical significant change from the preassessment to the follow-up assessment in the Tai Chi group ().
