Relación entre el video head impulse test (vHIT) y la prueba calórica en el estudio evolutivo de pacientes con neuritis vestibular

Unilateral Head Impulses Training in Uncompensated Vestibular Hypofunction

“…The vHIT and the caloric test of the VNG are known to present with different responses of the VOR, presumably due to stimulating the VOR at different frequencies. Redondo-Martínez et al [ 26 ] found no correlation between the VHIT, the caloric test, and the DHI test in patients with vestibular neuritis, none of which were indicative of the subjective clinical status of the patient at any given time. In line with recent scientific literature [ 26 – 28 ], our patient showed improved DHI and DVA without significant changes in her vHIT.…”

In line with recent scientific literature [ 26 – 28 ], our patient showed improved DHI and DVA without significant changes in her vHIT. One study [ 29 ] has demonstrated that persistent dizziness after VN is not significantly associated with sustained vestibular impairment as assessed by the quantitative search coil head impulse testing (qHIT); more specifically, severe vestibular deficit in the chronic patient group did not imply a high score on the shortened version of the Vertigo Symptom Scale (sVSS), assessing dizziness, vertigo, and imbalance during the past 12 months.…”

The spectrum of acute vestibular neuropathy through modern vestibular testing: A descriptive analysis

“…This study was designed to demonstrate primarily the value of vHIT in classifying the sub-variants of an acute peripheral vestibular syndrome, and consequently does not consider caloric testing as the gold standard since that test does not assess function of the vertical canals. Therefore, patients with caloric hypofunction yet normal H-SCC gain in vHIT could be missed; it is known that results from these tests can be discrepant ( Blodow et al, 2013 , Burston et al, 2018 , Fukushima et al, 2019 , Jung et al, 2017 , Mahringer and Rambold, 2014 , McGarvie et al, 2015 , Park et al, 2005 , Rambold, 2015 , Rubin et al, 2018 , Wegmann-Vicuña et al, 2018 , Yoo et al, 2016 ), and such discrepancies are believed to be attributable to the fact that the tests assess different frequencies of the vestibulo-ocular reflex ( McCaslin et al, 2014 , Redondo-Martínez et al, 2016 , Zellhuber et al, 2014 ).…”

Can Hashimoto's thyroiditis cause vertigo? [Czy choroba Hashimoto może być przyczyną zawrotów głowy?]

“…For years, videonystagmography has been the gold standard in the diagnosis of the vestibular organ [61,62]. The procedure consists of three tests recording spontaneous, gaze, and positional nystagmus.…”

“…Od lat wideonystagmografia (VNG, videonystagmography) jest złotym standardem w diagnostyce narządu równowagi [61,62]. Protokół badania składa się z trzech testów, podczas których wykonuje się zapis oczopląsu samoistnego, spojrzeniowego oraz oczopląsu wywołanego bodźcem położeniowym, jak również próby okulomotoryczne.…”
