Outline of Final Research Achievements |
The purpose of this study is to clarify the effects of presenting images that induce visually induced self-motion sensation (vection) using virtual reality (VR) on static standing posture. Vection refers to the sensation that one's own body is moving by visual perception. Based on a previous report that the peripheral vision plays an important role in vection, we investigated the effects on posture using VR, which is suitable for presenting images in the peripheral vision, in healthy young and elderly subjects. The results showed that when the presentation of images to the peripheral vision was restricted, the elderly showed less postural sway in the standing posture than when images were presented to the full field of vision. The younger subjects did not show the same difference as the older subjects.

Academic Significance and Societal Importance of the Research Achievements |
VRは映像提示の新しい手法であり、従来の映像提示に比べると、仮想空間に実際にいるような臨場感が得られ、その没入感覚が特徴とされている。一方で、その没入感覚によって、姿勢への影響が懸念される。本研究では、静止立位姿勢においてVRを用いたベクション刺激を観察することで、立位保持時の重心同様に影響が見られること、加えて若年者と高齢者を比較することで、ベクション刺激に対する姿勢制御の戦略が異なることが明らかになった。VRをリハビリテーション医療の現場でさらに広く活用するためにも、VRを用いているときの姿勢制御特性における重要な基礎的知見が得られた。
