“…In Ménière's disease, two major changes in cVEMP were seen as a result of possible lesions of the otolith organs: an elevated threshold and altered tuning [Rauch et al, 2004;Node et al, 2005;Lin et al, 2006;Kim-Lee et al, 2009]. As reported before, healthy subjects showed the best response (highest amplitude and lowest threshold) for cVEMP induced by an AC stimulus at a stimulus frequency of approximately 500 Hz.…”

“…It has been shown that AC sound is easy to use in a clinical setting and the stimulus characteristics can be controlled; for example, the duration, level and frequency of the stimulus can be easily changed. However, in most studies, solely one AC stimulus frequency, generally 500 Hz, was used for testing VEMP because this particular stimulus frequency was proven to be the most effective in evoking VEMP [Todd et Frequency Tuning of oVEMP in Normal Subjects and Ménière's Disease Audiol Neurotol 2012;17:12-19 13 al., 2000; Welgampola and Colebatch, 2001;Rauch et al, 2004;Node et al, 2005;Chihara et al, 2009a;Kim-Lee et al, 2009;Todd et al, 2009;Park et al, 2010].…”

Ocular vestibular evoked myogenic potentials (oVEMP) in response to 250-, 500- and 1000-Hz air-conducted short tone bursts were studied in 22 healthy subjects and 37 Ménière’s disease patients. The goal of this study was to investigate normal tuning characteristics of the oVEMP and the possible oVEMP changes with respect to frequency dependence in Ménière’s disease. In unilateral Ménière’s disease patients, a distinction was made between affected ears and unaffected ears. It was found that in normal subjects, the oVEMP tunes to a stimulus frequency of 500 Hz, with the highest amplitude and lowest threshold at this particular frequency. Generally, Ménière’s disease patients showed lower amplitudes and higher thresholds than normal subjects at all 3 stimulus frequencies in both the affected and the unaffected ear. Additionally, for ears affected by Ménière’s disease, the best stimulus frequency was 1000 Hz. With the use of this altered tuning for these ears, we tried to find a criterion for distinguishing normal from Ménière’s disease ears.

“…However, this 'best' frequency can lie between 500 and 1000 Hz 22 or between 500 and 700 Hz. 23 The alteration in tuning and threshold shift in Mé niè re's disease has been attributed to the presumed hydropic distension of the saccule. 23 In this study, T vestibular evoked myogenic potential was 116 + 7.7 dBSPL.…”

Introduction:The objectives of this preliminary, prospective, cohort study were to ascertain the characteristics of vestibular evoked myogenic potentials at threshold levels in two groups of Ménière's disease patients – acute and stable – and to identify whether vestibular evoked myogenic potentials can provide any specific, objective information to distinguish acute from stable Ménière's disease.Subjects and methods:The study was based at a tertiary neuro-otology centre. Twenty adult patients who fulfilled the American Academy of Otolaryngology–Head and Neck Surgery1 criteria for Ménière's disease were divided into two groups: 11 patients with acute Ménière's disease and nine patients with stable Ménière's disease. Eighteen healthy adult volunteers served as controls. All subjects underwent vestibular evoked myogenic potential testing with ipsilateral, short tone burst stimuli at 500 Hz, as well as pure tone audiometry. The patients also underwent caloric testing.Results:Vestibular evoked myogenic potentials were present in all controls, and were present in 65 per cent of patients but absent in 35 per cent. The mean absolute threshold (Tvestibular evoked myogenic potential) ± standard deviation in normal controls was 116 ± 7.7 dBSPL; this did not differ statistically from that in patients, nor did it differ between acute and stable Ménière's disease. The p13/n23 latencies at the threshold levels in the normal, acute and stable groups (mean ± standard deviation) were respectively: 15 ± 2.2 ms/23.0 ± 2.5 ms; 15.7 ± 0.9 ms/23.7 ± 0.9 ms; and 15.3 ± 2.0 ms/24.2 ± 1.9 ms. The mean interaural amplitude difference ratio (IAD) ± standard deviation was significantly higher in the stable group compared with the acute group (0.54 ± 0.33 vs −0.15 ± 0.22; p = 0.007) and with the controls (0.54 ± 0.33 vs 0.1 ± 0.22; p = 0.05).Conclusions:The parameter that best differentiated acute from stable Ménière's disease at threshold was the interaural amplitude difference ratio. Therefore, this parameter may be used to monitor the clinical course of Ménière's disease.

“…De acuerdo a la anatomía del laberinto, la EM podría afectar inicialmente a la parte más inferior (cóclea y sáculo), para ascender posteriormente hacia el utrículo y los CS [44]. También es posible que se produzca un cambio de sintonización, de manera que la mejor respuesta con VEMP por VA no sea a 500 Hz sino a 1 kHz [45], sugiriéndose incluso, que la relación de amplitudes entre 500 / 1000 Hz sería un fiel indicador de la enfermedad. En definitiva, los diversos hallazgos podrían deberse a diferentes estadios del proceso, a la influencia de las crisis agudas y a la actividad fluctuante de la enfermedad [5].…”
