Videonystagmography (VNG) is a type of testing used to assess vestibular and central nervous system function through the use of eye movement tracking, specifically evaluating nystagmus. [1] The older version of technology used to perform these tests, known as electronystagmography (ENG), leverages electrophysiological signals.
ENG or VNG can be used to record nystagmus during oculomotor tests such as saccades, pursuit and gaze testing, optokinetics and also calorics (dithermal or monothermal). Abnormal oculomotor test results may indicate either systemic or central pathology as opposed to peripheral (vestibular) pathology.
The test may need to be performed more than once, as it is not always easy to demonstrate observable nystagmus that is typical of BPPV. Also, the test results can be affected by the speed with which the maneuver is conducted and the plane of the occiput. [5] There are several disadvantages proposed by Cohen for the classic maneuver.
