VertiMobile vs SVV

The VertiMobile® app is designed for use with VertiMobile® Eye Movement Recording Goggles, supporting physicians or healthcare practitioners in the diagnosis and monitoring of balance disorders. The app enables users to record, save, and playback video clips of eye movements using a smartphone. By utilizing the VertiMobile® system, users are freed from the need to carry bulky equipment, making it ideal for performing quick gaze tests and BPPV maneuvers, with the added ability to record eye movements. Recordings are linked to tasks and stored within the app, where they can later be accessed for playback. This app does not provide a diagnosis or diagnostic recommendations.

Subjective Visual Vertical (SVV) is a test that measures the difference between a person’s perceived vertical and the true vertical. It evaluates gravity perception mediated by the otolith organs, vestibular nerve, and central vestibular pathways, and helps detect asymmetry of vestibular function. Using an audio/video remote control or a variety of game controllers, including those for Nintendo Switch, PlayStation, and Xbox, the user adjusts a displayed line until it is perceived as perfectly vertical. After repeating this procedure 10 times, the application calculates the mean deviation from the true vertical and the standard deviation.
