Description. This webinar explores how the combination of caloric, vHIT and rotational chair testing provides a multi-frequency assessment of the lateral semi-circular canal and can assist the clinician in diagnosing and treating vestibular disorders.

Unlike caloric testing in which each ear is independently evaluated, tests involving rotational chairs test both ears simultaneously. Rotational chair testing (RCT) is much more sensitive than caloric testing for identifying vestibular deficits (71% sensitivity for RCT, compared to 31% for calorics). 10 However, because the ears are not

Some have proposed that we do not need calorics anymore and that vHIT is an alternative and superior tool (MacDougall et al, 2009) to the caloric test, which has a long-standing reputation as the gold standard test for assessing loss of vestibular function. vHIT is an exciting and relatively new tool for assessment of the vestibular system with

The diagnosis was already well known from other tests (VENG and rotatory chair). The VHIT test in current practice (as of 1/2019) The VHIT test is a commercial version of the HIT test (head impulse test) using sophisticated eye tracking and head velocity transducers. This is presently the most useful version of the HIT test, mainly because it

During computerized rotary chair tests, the patient sits in a motorized chair that swivels side to side at a controlled rate. Screenings can be performed with the examiner watching the eyes while turning the subject side to side in a swivel chair. VIDEO HEAD IMPULSE TESTING (VHIT) vHIT also evaluates how well the eyes and inner ears work together.

For vestibular testing, an audiologist guides you through various simple tasks while asking questions. Audiologists specialize in hearing and balance disorders. These tests measure how your body's sensory systems that control balance work together. To feel balanced, your brain requires input from three systems working together: Vision (sight).

The potential limitations of vHIT in diagnosing MD or vestibular migraine (VM) are highlighted in a prospective study of patients evaluated with calorics and vHIT. 4 Caloric testing was abnormal in 67% of MD patients and 22% of VM patients, while vHIT had abnormal gain in 37% of MD and 9% of VM patients. No statistically significant difference

As indicated in Figure 1, vHIT, calorics, and rotational chair (RC) testing each measure a different frequency of the vestibular end-organs. For example, caloric tests measure nystagmus in response to very low frequency stimulation (0.003 Hz) and the rotational chair stimulus ranges from 0.1 Hz-0.64 Hz.

https://www.interacoustics.com/blog/is-rotational-chair-testing-needed-for-vestibular-assessments
The idea of a rotational chair was first introduced by Robert Bárány in 1907 and has been used for a variety of different clinical needs since that time. However, newer vestibular tests, such as the video head impulse test (vHIT) and vestibular evoked myogenic potentials (VEMP), question whether the rotational chair test battery is still a necessary component for a comprehensive vestibular

https://dizziness-and-balance.com/testing/Rchair/rchair.html
The purpose of rotational testing is to determine whether or not dizziness may be due to a disorder of inner ear or brain, and particularly to determine whether or not both inner ears are impaired at the same time.. There are three major parts to the test. (as well as a lot of add ons) The chair test measures dizziness (well jumping of the eyes really -- called nystagmus) while being turned

Combined VHIT and caloric testing in Meniere's disease. See also: conflicts between VHIT and rotatory chair testing. Many have recently pointed out that there is a pattern in Meniere's where the VHIT is normal and caloric is reduced. McGarvie et al (2015) discussed that calorics are more sensitive than VHITs to Meniere's.

For acute vestibular deficits, vHIT has a reported sen-sitivity of 68.84%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 62.5%.5 Other specificity and sensitivity reported in the literature is 92% and 36% when assessing an acute vertiginous event (with caloric testing as the gold standard).2 Finally

At this writing, the caloric, the VHIT, and rotatory chair tests are well established for diagnosis of bilateral vestibular loss. For example, Sargent et al (1997) used these tests to establish bilateral vestibular loss. So we have a low-frequency test (calorics), and a mixed frequency test (rotatory chair). The horizontal VHIT is very valuable

CALORIC TEST (a part of the ENG, VENG) The caloric test is a part of the ENG. It is an attempt to discover the degree to which the vestibular system is responsive and also how symmetric the responses are, between left and right ears. It is a test of the lateral semicircular canals alone -- it does not assess vertical canal function or otolithic
