Methods: The sample wascomposed of 18 individuals (36 ears), six men and 12 women. In theVEMP test in the time domain, 200 tone burst stimuli were promediatedat a frequency of 500 Hz, with 5.1 stimulations/s at an intensity of 95dBNAn. This was followed by capture in the frequency domain, where200 stimuli consisting of 500 Hz (carrier frequency) pure tones werepromediated and modulated at a frequency of 40 Hz. Odds ratio wascalculated and the chi-squared test was applied to compare the responsesof two domains. This is a cross-sectional contemporary cohort study.Results: VEMP in the time domain was recorded by unilateral stimulationand capture, with adequate morphology, in 88.88% of the ears. Inthe frequency domain test, a steady-state peak was found in 30 of the 36tests (83.33%). The chi-squared test and odds ratio calculation showeda strong relationship between the two domains. Conclusion: There is asignificant association between the VEMP tests in the time and frequencydomains, a finding that suppports its use in clinical practice. 2013 artículo científico 2317-6431 https://www.redalyc.org/articulo.oa?id=391544056004 en http://www.redalyc.org/revista.oa?id=3915 Audiology - Communication Research application/pdf Academia Brasileira de Audiologia Audiology - Communication Research (Brasil) Num.4 Vol.18 |
