ABSTRACT
Objective:
To establish a new method for detecting vestibular function by testing cervical vestibular-evoked myogenic potential induced by galvanic vestibular stimulation in normal population.Method:
Twenty normal ears were tested for cervical vestibular evoked myogenic potential induced by galvanic vestibular stimulation. SPSS 18.0 software was used to analyze the obtained data.Result:
In all healthy subjects mastoid-forehead galvanic vestibular stimulation produced a positive-negative biphasic EMG responses on SCM ipsilateral to the cathodal electrode. The latency of p13 wasï¼11.52±3.05ï¼ ms. The latency of n23 wasï¼15.31±3.38ï¼ ms. The amplitude of p13-n23 wasï¼40.55±27.93ï¼ µV. The interval of p13-n23 wasï¼3.53±1.38ï¼ ms. The interaural asymmetry ratioï¼AR, %ï¼ of p13, n23 latency, the amplitude and interval were respectivelyï¼6.96±6.79ï¼%, ï¼6.47±5.93ï¼%, ï¼28.08±26.42ï¼% and ï¼16.61±11.11ï¼%. There was no significant difference in all parameters between the right and left ears of all subjects.Conclusion:
The value of cervical vestibular-evoked myogenic potential induced by galvanic vestibular stimulation in normal subjects can be established to explore methods for diagnosis, treatment and researching mechanism of auditory neuropathy and vestibular neuropathy.Palavras-chave
