Fig. 2: The results of postural fluctuation properties and ankle kinematics properties for the control and EA groups.

The contrasts of standardized differences in postural fluctuation properties (sample entropy (SampEn) and mean frequency (MF)(A), and in ankle kinematics properties (root mean square (RMS) and ankle–plate mutual information (AP-MI))(B) between the two groups. (EA: error amplification) (The error bars on the bar charts represent standard error.).
