Virtual SVV

Subjective visual vertical testing made virtual

Spatial orientation and sensory-motor coordination rely on the accurate perception of verticality. The vestibular system provides the essential information for these tasks. Virtual SVV™ can functionally assess vestibular and otoneurologic function, while providing detailed quantitative data analysis.

The clinical background behind subjective visual vertical (SVV) testing

The vestibular system consists of three semicircular canals and two otoliths (utricle and saccule) in each ear. The semicircular canals perceive angular acceleration, while the otolith organs perceive linear acceleration. Otolithic dysfunction is typically accompanied by incorrect spatial orientation and postural instability. Thus, patients that suffer from this dysfunction may experience a perception of tilt.

  • Subjective measures with quantitative data analysis
  • Behavioral evaluation of vestibular and otoneurologic function
  • Sensitive to tilt at different head positions
  • Game-like procedure is easy to understand and fun for children
