FIG. 3.

Gain response and root mean square (RMS) from galvanic vestibular stimulation (GVS) in anterior/posterior (AP) direction. Experimental (EXP) group shows significant decrease in gain from Pre to Hr0 and significant increase in gain from Hr0 to Hr24 for leg angle, trunk angle, and center of mass (COM). RMS across all conditions shows no changes in overall sway across time and group. (A) Gain of leg segment angle relative to GVS. (B) Gain of trunk segment angle relative to GVS. (C) Gain of COM relative to GVS. (D) Overall sway of leg angle in RMS during GVS. (E) Overall sway of trunk angle in RMS during GVS. (F) Overall sway of COM in RMS during GVS in EXP and control (CON) groups. Error bars represent standard error of the mean. *Represents significant group effect from analysis of covariance with pre-test set as covariate (p < 0.05). **Represents significant time effect from two-tailed paired t test (p < 0.017).
