Beyond 2D eye recordings: The importance of measuring torsion and dynamic head movements in the diagnosis and treatment of BPPV 

Presenters: Michelle R. Petrak, PhD & Darren Whelan

Learning objectives

• The benefits of using an accelerometer to detect head position during BPPV assessment
• The benefits of using a torsion algorithm to identify the affected canal in BPPV
• The benefits of pairing 3D eye recordings with the TRV chair
