The effect of alcohol on cervical and ocular vestibular evoked myogenic potentials in healthy volunteers

Highlights • Consumption of alcohol up to a maximum BrAC of 1.5‰ (mean 0.97‰) had a selective dampening effect on oVEMP amplitude, while there was no effect of alcohol on oVEMP latency or cVEMP amplitude or latency. • Optokinetic stimulation also reduced oVEMP amplitude by decreasing the mean level...

Zusammenfassung:	Highlights • Consumption of alcohol up to a maximum BrAC of 1.5‰ (mean 0.97‰) had a selective dampening effect on oVEMP amplitude, while there was no effect of alcohol on oVEMP latency or cVEMP amplitude or latency. • Optokinetic stimulation also reduced oVEMP amplitude by decreasing the mean level of gaze and inferior oblique muscle activity throughout the recording. • cVEMPs and oVEMPs can be reliably recorded in subjects who are under the influence of alcohol or have nystagmus, providing that they can cooperate and achieve a reasonable mean level of up-gaze during the recording.
