The base station is connected to a standard USB port on the Windows PC. The base station communicates with the virtual reality goggle via via a wireless receiver and transfers the measurement data to the software.

The Virtual SVV^TM software provides the operator with a comprehensive online real-time display for the monitoring of the patient’s head position and angle of the luminous line while the patient is performing the task. Throughout the test procedure the deviation of the luminous line from the true vertical is displayed. Each SVV estimate confirmed by the patient is entered on a chart against the expected threshold range. Upon completion of the examination all data are stored and a report sheet is generated that can be output in PDF or hardcopy form.

The lightweight, light-occluding virtual reality goggle provides the patient with a display of the luminous line, which can be rotated using the buttons on the wireless handheld remote. Integrated into the goggle is a sensor that provides continuous information on the head position.

Exchangeable foam face cushions allow for form fitting to each individual’s face, ensuring the occlusion of any ambient light during the examination.

The rechargeable battery provides for operation over several hours. It is automatically recharged when placed in the cradle of the base station.

The Virtual SVV^TM aids in the diagnosis and rehabilitation of vestibular dysfunction. It provides a simple technique for assessing the function of the utricle. It’s suitable for kids, providing a game-like experience that makes it easier to get good corporation between clinician and patient.

An individual with a healthy otolith system can easily determine what is vertical with great precision. The estimation of the subjective visual vertical thus serves as a behavioral evaluation of utriclular function. Clinical research has already demonstrated that isolated utricular dysfunction can occur.

Virtual SVV^TM complements the traditional vestibular assessment battery, allowing you to now accurately test all 10 balance organs in every patient.

Static testing performed with the head in an upright position provides the examiner with more precision than the traditional SVV bucket test.

In the presence of an otolith disorder the patient is likely to experience a sensation of tilt and accordingly, will set the luminous line with some deviation relative to head axis, i.e. relative to gravity.
