Increasing the Stimulation Rate Reduces cVEMP Testing Time by More Than Half With No Significant Difference in Threshold.

Objective: Assessing the effect of a higher stimulation rate in cervical vestibular evoked myogenic potential (cVEMP) outcome measurements. Study Design: Prospective cohort study. Setting: Large specialty hospital, Department of otolaryngology. Subjects: Eleven healthy subjects were used in this study. Intervention: All subjects underwent a cervical vestibular evoked myogenic potential test at 500, 750, and 1000 Hz using 5 and 13 Hz stimulation rates. Main Outcome Measures: Threshold, peak-to-peak (PP) amplitude, and interaural asymmetry ratio (IAR). Results: PP cVEMP amplitudes were larger at 5/s than at 13/s. The 5/s to 13/s differences were statistically significant at 500 and 750 Hz (p
