Note. Values are shown as mean ± standard deviation or mean (95% confidence interval).

RL, right-left (a positive value means right displacement); AP, anteroposterior (a positive value means anterior displacement); SI, superior-inferior (a positive value means superior displacement); 3D, root mean square.
