Abstract
SEGURA-HERNANDEZ, Mónica et al. Comparison of ocular vestibular myogenic response by acoustic stimulation at 500 and 1000 Hz in healthy subjects. Cir. cir. [online]. 2019, vol.87, n.6, pp.640-644. Epub Nov 22, 2021. ISSN 2444-054X. https://doi.org/10.24875/ciru.19000791.
Objective:
To compare the amplitude of potentials by acoustic stimulation at 500 Hz versus 1000 Hz in healthy subjects.
Methods:
25 subjects; potentials were performed with acoustic stimuli burst-type at 500 and 1000 Hz with a stimulation rate of 5.1 at 100 dB in both ears. Descriptive statistics tests were performed, confidence intervals were calculated for the mean with 95% reliability, standard error graphs and t-test for related samples.
Results:
The values obtained in amplitude when performing an acoustic stimulus at 1000 Hz show a faster response compared to that obtained in the frequency of 500 Hz. The t-test showed a significant difference in the amplitude in the 1000 Hz frequency between ears with a significance value of p < 0.025.
Conclusions:
It is strengthened the hypothesis that in the amplitude of potentials by aerial acoustic stimulation in the frequency of 1000 Hz a greater amplitude is generated in relation to the one generated in the frequency of 500 Hz.
