Description

Human controls their balance through variety of sensors and one of it is visual input. Previous study found that the visual proprioceptive information is more potent than the nonvisual. In this research, authors conducted an experiment on the implementation virtual reality (VR) as visual perturbation combined with single-support stance to distort human’s balance. This research focused on the single-support stance where subject stood on their dominant leg during the experiment with VR goggle.

Human maintain their balance to prevent fall and injury. People wasted their money for the treatments to recover from the injury caused by this factor. Falls also lead people to other dangerous or harm situation. Several sensory inputs work together to maintain human’s balance such as vestibular, proprioceptive and visual systems. In this paper, authors focused the research on the visual stimulation on human’s balance.

Previous study suggested that the visual proprioceptive information is more potent than the nonvisual. Any alteration in visual input can trigger different individual’s response to anticipate the environmental conditions. In 1974, Lee and Aronson conducted a research related with visual perturbation to distract human infant’s balance as shown in figure 1 [1]. In this research, they built the physical experimental room comprising three walls and a ceiling and the walls were moveable in backward and forward direction. At the beginning of experiment session, the infant subject stood in the middle of the stationary experimental room then after couple seconds the researcher moved the walls and recorded subject’s reactions.
