Current Role of the Videonystagmography Examination in the Context of the Multidimensional Balance Function Test Battery

ABSTRACT

Assessment of the vestibular system once consisted of electronystagmography (ENG), and now more recently, videonystagmography (VNG). Over the last few decades this standard assessment has been expanded into a balance function assessment. The area of balance assessment now incorporates many different fields of study and possesses a strong research base. This multidisciplinary collaboration has resulted in newer tests such as vestibular-evoked myogenic potential (VEMP) and off-axis rotation. However, despite its age, the ENG/VNG examination still remains the bedrock test of the balance function test battery. This article describes the role of the ENG/VNG examination in the contemporary assessment of vertigo, dizziness, and imbalance.
