Functional testing of the utricles
Virtual SVV™ aids in the diagnosis and rehabilitation of vestibular dysfunction. It provides a non-invasive technique for differential diagnosis of the vestibular apparatus. Virtual subjective visual vertical (SVV) testing is particularly prudent for diagnosing the otolith organs. In particular, SVV testing is a functional test of the utricles.
An efficient test of perceived verticality
An individual with a healthy otolith system perceives verticality with great precision. The estimation of the subjective visual vertical (SVV) thus serves as a behavioral evaluation of utricular function.
