PURPOSE: Determine whether there is an association between VEMP in the time domain and the frequency domain. METHODS: The sample was composed of 18 individuals (36 ears), six men and 12 women. In the VEMP test in the time domain, 200 tone burst stimuli were promediated at a frequency of 500 Hz, with 5.1 stimulations/s at an intensity of 95 dBNAn. This was followed by capture in the frequency domain, where 200 stimuli consisting of 500 Hz (carrier frequency) pure tones were promediated and modulated at a frequency of 40 Hz. Odds ratio was calculated and the chi-squared test was applied to compare the responses of two domains. This is a cross-sectional contemporary cohort study. RESULTS: VEMP in the time domain was recorded by unilateral stimulation and capture, with adequate morphology, in 88.88% of the ears. In the frequency domain test, a steady-state peak was found in 30 of the 36 tests (83.33%). The chi-squared test and odds ratio calculation showed a strong relationship between the two domains. CONCLUSION: There is a significant association between the VEMP tests in the time and frequency domains, a finding that suppports its use in clinical practice.
