We equip our diagnostic and treatment team with the latest, most advanced medical technologies to isolate and treat weak or non-functioning portions of the tiny vestibular anatomy of the inner ear. (dizziland.com)
The inner ear consists of the cochlea, the vestibular labyrinth, and the vestibulocochlear nerve. (mskneurology.no)
Collectively this system of the inner ear is termed the vestibular system or vestibular apparatus. (revitalhealth.ca)
Sensory information from the inner ear is relayed to the brain via the vestibular portion of the eighth cranial nerve (CNVIII), which is also called the vestibulocochlear nerve. (revitalhealth.ca)
If one inner ear is affected by disease or injury then the sensory input being sent to the brain will falsely indicate movement from that vestibular system. (revitalhealth.ca)

The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. (lookformedical.com)
In the electrophysiological experiments it has been shown that the latent time between electric stimulation of the labyrinth and response of the vestibular nerve is about 0.9 ms. This is a little bit shorter, then the same for cochlear - 1.0-1.1 ms. So we might assume this value of about 1.0 ms to be the latency of the first peak of the short latency VestEP (angular VsEPA and linear VSEPL). (happyvertigo.com)

Aetna considers vestibular autorotation test (VAT) experimental and investigational for the diagnosis of individuals with vestibular disorders, vestibular migraine, or any other indications because its sensitivity, specificity, reproducibility, and clinical utility have not been demonstrated. (aetna.com)
Although some published studies have suggested that the VAT may be useful in evaluating patients with vestibular disorders/diseases, there are few studies that examined the sensitivity and specificity of the VAT in evaluating patients with suspected vestibular abnormalities. (aetna.com)
Furthermore, there is a lack of data supporting the value of the VAT in the management of patients with vestibular disorders/diseases. (aetna.com)
Dynamic Posturography Aetna considers dynamic posturography (also known as balance board testing, computerized dynamic posturography [CDP], equilibrium platform testing [EPT], and moving platform posturography) experimental and investigational for the diagnosis and staging of patients with Meniere's disease and other balance disorders, for the differential diagnosis of multiple sclerosis and disequilibrium, and all other indications because its clinical value has not been established.

With the advent of Video Head Impulse Testing (vHIT) , many researchers and clinicians alike have questioned whether or not we really need to include both tests in our assessment of vestibular function. (e3diagnostics.com)
vHIT is an exciting and relatively new tool for assessment of the vestibular system with certain advantages over caloric testing. (e3diagnostics.com)
The review of recent literature indicates that vHIT is not a replacement for caloric testing but, rather, is another tool to keep in our vestibular assessment toolbox. (e3diagnostics.com)
Both calorics and vHIT remain necessary parts of the multidimensional vestibular assessment battery. (e3diagnostics.com)

To examine the pathophysiological features of patients with vestibular impairments associated with SSNHL, many instrumental vestibular evaluations, such as caloric test and vestibular evoked myogenic potentials (VEMPs), have been explored ( 6 , 7 ). (frontiersin.org)

As far as caloric testing is concerned, whatever method is used: convection current, the thermal gradient between the two ends of the canal, direct stimulation of the sensory cells, it does not hamper, in situations where @ the response is a left-beating nystagmus. (vestib.org)
Conversely, again and again caloric stimulation makes the "straight ahead" reference lean towards the right-hand-side of the head. (vestib.org)

CDP results demonstrated substantial improvements in postural sway in the vestibular conditions (5 and 6) as well as composite scores with the device 'off' and 'on' at the 1-month, 4-month, 1-year, and 2-year intervals. (scienceopen.com)

CI has a negative effect on the results of caloric and VEMP tests, but not on vHIT, indicating that the otolith and low-frequency semicircular canal (SCC) are more vulnerable to damage from CI. (scienceopen.com)
Our purpose was to explore the pathophysiological mechanism and investigate the clinical implications of video head impulse test (vHIT) in these patients. (frontiersin.org)
As a newly developed test, the video head impulse test (vHIT) assesses the angular VOR function of six SCCs within the physiological frequency range (5-7 Hz) ( 9 ). (frontiersin.org)
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. (e3diagnostics.com)
vHIT is also an effective test for evaluation of semicircular canal function in the pediatric population and may be able to provide information when caloric testing is contraindicated (Hamilton et al, 2015). (e3diagnostics.com)
Yet another distinct advantage of vHIT testing is that it stimulates the VOR using a more physiological high frequency stimulus than caloric testing. (e3diagnostics.com)
Advantages and disadvantages aside, the overwhelming conclusion is that calorics and vHIT do not provide redundant information regarding horizontal semicircular canal function but, instead, are complementary to one another (McCaslin et al, 2014). (e3diagnostics.com)
The caloric response stimulates the vestibular system at a very low frequency of approximately .003 Hz, while vHIT is performed by the examiner thrusting the patient's head in a much higher frequency range up to 5 Hz. (e3diagnostics.com)
As a result, the vHIT and the caloric show different VOR responses (Redondo-Martinez et al, 2015). (e3diagnostics.com)
With respect to Ménière's disease, studies have shown that caloric results are more often abnormal than vHIT results (McCaslin et al, 2015). (e3diagnostics.com)

The paper asserts that the cognitive, vestibular, and oculomotor effects the researchers measured are objective in nature, comparing them to the effects seen following concussion - even though the subjects had experienced no head injury. (lww.com)
Other factors that affect the degree of individual compensation include overall physical status, the functional status of remaining sensory systems, integrity of central brain mechanisms, age, and higher sensory functions such as memory, motor coordination, and cognitive ability. (medscape.com)
Most of which seemed like cognitive tests. (idmorgan.com)

Between 1997 to 2001, a prospective observational study was carried out in a tertiary care medical center to assess the effects of unilateral CI on the vestibular system. (scienceopen.com)
In spite of these advantages, caloric testing has been shown to have a high degree of sensitivity and specificity in the evaluation of unilateral vestibulopathy (Eza-Nunez et al, 2014). (e3diagnostics.com)

Patients with improved caloric function had received significantly lower mean (1.5 ± 0.7 Gy, p=0.01) and maximum doses (4 ± 1.5 Gy, p =0.01) to the vestibule. (researchsquare.com)
