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 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.
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 ...
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.
Tullio phenomenon, sound-induced vertigo, dizziness, nausea or eye movement was first described in 1929 by the Italian biologist Prof. Pietro Tullio.(1881–1941) [1] [2] During his experiments on pigeons, Tullio discovered that by drilling tiny holes in the semicircular canals of his subjects, he could subsequently cause them balance problems when exposed to sound.
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]
The DizzyFIX is a home medical device designed to assist in the treatment of benign paroxysmal positional vertigo (BPPV) and its associated vertigo. [1] The device is a head-worn representation of semi-circular canals. The device is filled with fluid and a particle representing the otoconia (loose hard particles) associated with BPPV.
Another method, known as the bucket test, uses a bucket over a patient's head. The clinician rotates the bucket until a line at the bottom of the bucket is perceived to be vertical. The Subjective Virtual Visual goggle is a trademarked method, which employs a goggle displaying a vertical line and a hand-held remote.
