Comparing the effects of different circular vection stimuli on upright stance.

Background: Upright quiet stance is maintained through the complex integration of sensory information from the visual, vestibular, and somatosensory systems [1]. Virtual reality (VR) is a well-established tool that has been used to study sensory contributions to balance and induce visual perturbations. Previous assessments of virtual environments have suggested that VR can be used to create various visual stimuli that affect balance [2]; however, there is limited work examining which dynamic visual stimulus, in the form of circular vection (CV), is the most effective at inducing whole body lean.
