Abstract

To assess indirectly the effects of virtual reality (VR) immersion on postural sway in thirteen healthy individuals. The ellipse sway area was recorded with an accelerometer coupled to an electrical shuttle balance under six conditions, varying Romberg and single leg stance (SLS) position with eyes open and eyes closed. The length of the ellipse traveled over 10 s was measured and Romberg and single leg stance (SLS) ratios were calculated. Ellipse sway area was reduced in all positions after VR intervention. Statistical differences were observed in the left SLS ratio 24 hr after comparison to the baseline. A single VR session could reduce ellipse sway area and decrease the visual dependency of posture control indicating increased ability to maintain stable body sway over the shuttle.

摘要

间接评估虚拟现实 (VR) 沉浸对 13 名健康个体姿势摇摆的影响。在六种条件下，使用与电动穿梭天平耦合的加速度计记录椭圆摇摆区域，在睁眼和闭眼的情况下改变 Romberg 和单腿站立 (SLS) 位置。测量椭圆的长度超过 10 秒，并计算 Romberg 和单腿站立 (SLS) 比率。VR 干预后，所有位置的椭圆摇摆面积都减少了。在与基线比较后 24 小时，观察到左侧 SLS 比率的统计差异。单个 VR 会话可以减少椭圆摇摆区域并降低姿势控制的视觉依赖性，表明在穿梭机上保持稳定身体摇摆的能力增强。
