Purpose: This study examined the effects of subjective visual vertical perception and head orientation on static balance control. Methods: The subjects were 25 young and healthy adults. The vertical perception was measured using a subjective visual vertical (SVV), and the Center of pressure (COP) parameter was analyzed by continuously measuring the movement of the COP to determine the chang- es in static postural control. The group was divided based on a deviation of 3° in SVV (11 of SVV ≥ 3°, 14 of SVV < 3°) and measured with different head orientations: front, up, down, left, and right in the upright and tandem positions, respectively. Results: In the upright position, the SVV ≥ 3° group had significantly larger values for all COP parameters (Sway length, Surface, Delta X, Delta Y, and Average speed) compared to the SVV < 3° group (p < 0.05). In the tandem stance, only the Ellipse Surface value was signifi- cantly larger among the COP parameters in the group with SVV ≥ 3° compared to the group with SVV < 3°(p < 0.05). In contrast, the oth- er COP parameters were not significantly different (p > 0.05). The effects of static balance control on the head orientation were not sta- tistically significant (p > 0.05), and the interactions between the subjective vertical perception and head orientation were not significant (p > 0.05). Conclusion: These results suggest that pathological deviations in SVV are associated with impaired static balance performance. This study can provide a therapeutic rationale for using visuospatial cognitive feedback training to improve the static balance.
