Why Does It Work? The innovation is based on the existing relationship between the visual and vestibular systems, and more precisely on the visual capacity to directly affect the vestibular and therefore postural balance. Physiological reasons What is the vestibular system? • As the basis of our sense of balance, the vestibular system is the main sensory system which perceives movement in three dimensions and provides orientation in relation to the vertical. Located in the inner ear, it is composed in particular of the vestibular nerve which activates four nuclei. As the actual centers of sensorymotor integration for the movements that the body makes, these nuclei feed into the spine. The visual system is connected to the vestibular system through these nuclei.

Origin cells - Lateral vestibular nucleus 2. The path is straight and passes through the entire length of the spinal cord. Located in the ventral funiculus. 3. The vestibular system can influence the ipsilateral proximal muscles.

These receptors and sensors are located in the skin and muscles.
Links between the vestibular system, visual system, and proprioceptive system can be easily observed. Vestibular system and visual system • When you try to visually follow swirling images projected in a circle on a screen, the ocular movements that you make will trigger dizziness after twenty seconds. This shows that visual stimulation affects the vestibular system. • Another example: when we see the train next to us pull away, we often get the impression that it is our train which is moving. In this case, the visual system was prioritized over the vestibular system. Vestibular system and proprioceptive system • In the case of dizziness or loss of balance triggered by a loss of information from the vestibular system, the simple action of touching a horizontal or vertical surface with our fingers allows us to find our balance again. Like the visual system, the proprioceptive system can also affect the vestibular system.

Our physiology shows that acting on the visual system can have a direct effect on an individual‘s balance and verticality. This hypothesis is verified by recent studies confirming that the visual system has priority over the vestibular system, beyond the links between them.
