Abstract
[Purpose] To examine the influence of visual information of location on the standing postural control of healthy adults. [Subjects] Twenty-one healthy adults (mean age, 24.0 ± 2.5 years). [Methods] Subjects adopted a step stance on a force-plate measuring body sway, and fixed their eyes on a point in front of them. Measurements were taken under 5 conditions of visual information: a column positioned immediately in front (0˚), and radially at 20˚, 40˚ and 60˚, and no visual information (control). [Results] The body sway path length and envelope area of the 0˚ and 20˚ conditions had significantly lower values than those of the 40˚ and 60˚, and control conditions. [Conclusion] The results suggest that when visual information exists near the central field of vision, where it is easy to generate visual discrepancies, it contributes to standing postural control.
