Objective:
Vestibular evoked myogenic potential (VEMP) has been utilized in clinic to test the function of saccule. In the present study, 3 stimulus modes were applied to 21 normal adults and intended to draw in a clinical test protocol.
Methods:
The normal latency and amplitude of VEMPs of 21 normal subjects were recorded and the ratio of bilateral amplitudes and asymmetry were calculated.
Results:
The response to binaural clicks were similar to the response of the monaural clicks. The interindividual variation in amplitude were large, but the latency varied little.
Conclusions:
VEMPs is a stable myogenic potentials. Monaural and binaural clicks stimulus can be used in clinical practice. The latter is appropriate for normal hearing subjects. Amplitude measurement is probable to evaluate the asymmetry of bilateral saccular function and may reveal saccule lesion.
