“…The study by Sandhu et al (2013) introduced a bellytendon electrode montage which was shown to result in significantly larger amplitude oVEMP responses in otologically normal participants. This finding of increased amplitude responses when using the belly-tendon electrode montage was confirmed by Vanspauwen et al (2017) and Makowiec et al (2017). Such studies confirm the belief that reference contamination can result in significantly reduced amplitude responses and contamination is attributed to the location of the reference electrode relative to the active electrode.…”

“…This electrode montage is referred to as the ''bellytendon'' montage. Sandhu et al (2013), Vanspauwen et al (2017), and Makowiec et al (2017) obtained significantly larger amplitude responses measured with the belly-tendon montage in otologically normal participants compared with amplitudes measured with the infraorbital montage. This belly-tendon electrode montage is felt to be optimal because of the lessened likelihood of reference contamination as the inverting electrode is placed over a tendon, which is believed to be electrically neutral (Piker et al, 2011).…”

The purpose of this investigation was to evaluate the sensitivity and specificity of the ocular vestibular evoked myogenic potential (oVEMP) using two electrode montages in patients with confirmed unilateral superior semicircular canal dehiscence syndrome (SCDS).This study evaluated oVEMP response characteristics measured using two different electrode montages from 12 unilateral SCDS ears and 36 age-matched control ears (age range = 23–66). The oVEMP responses were elicited using 500 Hz tone-burst air conduction stimuli presented at an intensity of 95 dB nHL and a rate of 5.1/sec. The two electrode montages used are described as an “infraorbital” montage and a “belly-tendon” montage.Balance function laboratory embedded in a large, tertiary care otology clinic.The belly-tendon electrode montage resulted in significantly larger amplitude responses than the infraorbital electrode montage for the ears with SCDS and the normal control ears. For both electrode montages the ear with SCDS exhibited a significantly larger amplitude response, ∼50% larger than the response amplitude from the normal control ear. The belly-tendon montage additionally produced larger median increases in amplitude compared with the infraorbital montage. Specifically, the median increase in oVEMP N1-P1 amplitudes using the belly-tendon montage was 39% greater in control ears, 76% greater in the SCDS ears, and 17% greater in the contralateral SCDS ears.The belly-tendon electrode montage yields significantly larger oVEMP amplitude responses for participants with SCDS and normal control participants.

“…Contamination from other muscles may weaken the laterality of the reflex and reduce its clinical utility. The standard closely-spaced differential montage is associated with smaller amplitudes than montages with reference located much further away; for example, on the chin (Piker et al, 2011, Zuniga et al, 2014), sternum (Vanspauwen et al, 2017) or earlobes (Rosengren et al, 2005). This is because the standard montage prioritizes specificity over amplitude (some of the IO signal will be subtracted out, but so will activity from nearby extraocular muscles).…”

“…There have been recent reports of greater oVEMP amplitudes using more lateral active recording electrodes in normal subjects, with reference electrode located either beneath the eye (Govender et al, 2016) or on the medial canthus (Sandhu et al, 2013, Makowiec et al, 2017, Vanspauwen et al, 2017). However, Piker et al (2018) showed that the medial canthus is not an electrically indifferent site.…”

“…Cervical and ocular vestibularevoked myogenic potentials (cVEMP/oVEMP) were measured to assess saccular and utricular function, respectively (55,56). When responses were seen at or below 100 dB Hearing Level during (air conducted) cVEMP testing, saccular function was considered to be present, otherwise absent (55). For (bone conducted) oVEMP stimulation, this normal value is ≤140 dB Force Level (56).…”

Hearing loss is one of the most prevalent disabilities worldwide, and has a significant impact on quality of life. The adult-onset type of the condition is highly heritable but the genetic causes are largely unknown, which is in contrast to childhood-onset hearing loss. We identified an in-frame deletion of 12 nucleotides in RIPOR2 as a highly penetrant cause of adult-onset progressive hearing loss that segregated as an autosomal dominant trait in 12 families from the Netherlands. Hearing loss associated with the deletion in 63 subjects displayed variable audiometric characteristics and an average age of onset of 30.6 years (SD 14.9 years, range 0-70 years). A functional effect of the RIPOR2 variant was demonstrated by aberrant localization of the mutant RIPOR2 in the stereocilia of cochlear hair cells and failure to rescue morphological defects in RIPOR2-deficient hair cells, in contrast to the wildtype protein. Strikingly, the RIPOR2 variant is present in 18 of 22,952 individuals not selected for hearing loss in the Southeast Netherlands. Collectively, these data demonstrate that an inherited form of adult-onset hearing loss is relatively common, with potentially thousands of individuals at risk in the Netherlands and beyond, which makes it an attractive target for developing a (genetic) therapy.
