“…Many of the previous bone conduction studies that have been published are concerned with defining the optimal stimulus parameters for bone conduction, as well as demonstrating that the cVEMP can be recorded in response to BC stimuli in the presence of a conductive hearing loss (Sheykholeslami et al 2000Seo et al 2008). However, there are several problems that arise when trying to compare threshold values in response to these two types of stimuli, as well as other response metrics across studies.…”

The present experiment provided a direct comparison of the cVEMP in response to AC versus BC 500 Hz short-duration toneburst stimuli in the same subjects. The results of the present experiment also provide insight into the laterality of the cVEMP response and reveal that the cVEMP may not be completely ipsilateral (i.e., there may be a form of bilateral interaction that occurs when both sides are stimulated simultaneously). Last, the results indicate that BC stimuli likely activates the saccule as well as the utricle, given that AC VEMPs can be masked by the administration of BC masking noise presented to the midline.

“…BC stimulation has been used in several clinical studies, for example in patients with otitis media (e.g. Monobe and Murofushi, 2004;Seo et al, 2008;Yang and Young, 2003), but has not become a standard cVEMP stimulus, possibly due to the need for an additional amplifier to provide sufficient drive to the bone conductor.…”

“…Many authors consequently normalize the VEMP amplitude by dividing it by a measure of the muscle tone (e.g. Karino et al, 2005;Welgampola and Colebatch, 2005;Miyamoto et al, 2006;Brantberg et al, 2007;Sandhu and Bell, 2008;Seo et al, 2008;Brantberg and Verrecchia, 2009 providing an unequivocal signature of the inhibition arising from the vestibular end organs.…”

Measuring the vestibular evoked myogenic potential (VEMP) promises to become a routine method for assessing vestibular function, although the technique is not yet standardized. To overcome the problem that the VEMP amplitude depends not only on the inhibition triggered by the acoustic stimulation of the vestibular end organs in the inner ear, but also on the tone of the muscle from which the potential is recorded, the VEMP is often normalized by dividing through a measure of the electromyogram (EMG) activity. The underlying idea is that VEMP amplitude and EMG activity are proportional. But this would imply that the muscle tone is irrelevant for a successful VEMP recording, contradicting experimental evidence. Here, an analytical model is presented that allows to resolve the contradiction. The EMG is modeled as the sum of motor unit action potentials (MUAPs). A brief inhibition can be characterized by its equivalent rectangular duration (ERD), irrespective of the actual time course of the inhibition. The VEMP resembles a polarity-inverted MUAP under such circumstances. Its amplitude is proportional to both the ERD and the MUAP rate. The EMG activity, by contrast, is proportional to the square root of the MUAP rate. Thus, the normalized VEMP still depends on the muscle tone. To avoid confounding effects of the muscle tone, the standard deviation of the EMG could be considered. But the inhibition effect on the standard deviation is small so that the measuring time would have to be much longer than usual today.
