Unterberger test: Video documentation with image overlay. The Unterberger test, also Unterberger's test and Unterberger's stepping test, is a test used in otolaryngology to help assess whether a patient has a vestibular pathology. [1] It is not useful for detecting central disorders of balance. [2]
The roll test can determine whether the horizontal semicircular canal is involved. [24] The roll test requires the person to be in a supine position with their head in 30° of cervical flexion. Then the examiner quickly rotates the head 90° to the left side, and checks for vertigo and nystagmus.
Vertiginous epilepsy has also been referred to as epileptic vertigo, vestibular epilepsy, vestibular seizures, and vestibulogenic seizures in different cases, but vertiginous epilepsy is the preferred term.
The HINTS test, which is a combination of three physical examination tests that may be performed by physicians at the bedside, has been deemed helpful in differentiating between central and peripheral causes of vertigo. [32] The HINTS test involves the horizontal head impulse test, observation of nystagmus on primary gaze, and the test of skew ...
Epley maneuver. The Epley maneuver or repositioning maneuver is a maneuver used by medical professionals to treat one common cause of vertigo, benign paroxysmal positional vertigo (BPPV) [1] [needs update] of the posterior or anterior canals of the ear. [2]
This test can provide site-specific information on vestibular system and its function. [25] Another way of testing the VOR response is a caloric reflex test, which is an attempt to induce nystagmus (compensatory eye movement in the absence of head motion) by pouring cold or warm water into the ear. Also available is bi-thermal air caloric ...
The negative predictive value of this test is not 100%. Some patients with a history of BPPV will not have a positive test result. The estimated sensitivity is 79%, along with an estimated specificity of 75%. 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.
Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system. [1] Electronystagmography is used to assess voluntary and involuntary eye movements. [2]
