“…Compared to oVEMPs elicited in response to ACS, BCV oVEMPs show higher response prevalences and greater amplitudes in healthy subjects Wang et al, 2010). In subjects with conductive hearing loss, BCV oVEMPs are usually normal whereas ACS oVEMPs are affected.…”

“…In the last decade, various ways of VEMP stimulation have been investigated, such as air-conducted (AC) sound, bone conducted (BC) sound and vibration and galvanic stimuli, both mono-and binaurally [Rosengren et al, 2005Chihara et al, 2007Chihara et al, , 2009bWelgampola, 2008;Welgampola et al, 2009;Wang et al, 2010]. 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.…”

Ocular Vestibular Evoked Myogenic Potentials: Frequency Tuning to Air-Conducted Acoustic Stimuli in Healthy Subjects and Ménière’s Disease

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.

“…Consecutive runs were performed to confirm the reproducibility of the p13 and n23 peaks. At our laboratory, the norm of the p13 latency of BCV-cVEMPs is 14.4 ± 1.5 ms. Those with p13 latency exceeding 17.4 ms are defined as delayed response [14].…”

This study applied both ocular vestibular-evoked myogenic potential (oVEMP) and cervical VEMP (cVEMP) tests in patients with cerebellar disorders to determine whether VEMP test can differentiate between cerebellar and brainstem lesions. A total of 12 patients with cerebellar disorder, including extended cerebellar lesion (involving the brainstem) in 8 and localized cerebellar lesion (excluding the brainstem) in 4, were enrolled in this study. All patients underwent caloric, visual suppression, and oVEMP and cVEMP tests via bone-conducted vibration stimuli. The abnormal rates for the caloric, visual suppression, and oVEMP and cVEMP tests were 62, 83, 88 and 75% in patients with extended cerebellar lesion and 0, 25, 0 and 0% in those with localized cerebellar lesion, respectively. The rate of abnormal oVEMP results significantly differed between the two groups, but caloric, visual suppression and cVEMP test results did not differ. In another ten healthy subjects, characteristic parameters of oVEMPs obtained under light and dark conditions did not significantly differ. In conclusion, ocular VEMP test can differentiate between cerebellar and brainstem lesions. Abnormal oVEMPs in patients with cerebellar disorder may indicate adjacent brainstem involvement.
