Comparison of static balance control ability between MCI group and control group under the eyes open condition

Note. (A) ~ (G) represents the comparison of balance parameters between MCI group and control group under the eyes open condition. RMS = Root mean squared; RMS_ml = Root mean squared in the ML direction; RMS_ap = Root mean squared in the AP direction; MVELO = the average velocity of the COP; MVELO_ml = the average velocity of the COP in the ML direction; MVELO_ap = the average velocity of the COP in the AP direction; 95%AREA-CE = the 95% confidence ellipse area of the COP. a, significant difference between groups. b, significant difference between types of support surface
