Comparison of ocular vestibular myogenic response by acoustic stimulation at 500 and 1000 Hz in healthy subjects.
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.
