Abstract：
INTRODUCTION:Vestibular evoked myogenic potential (VEMP) elicited by acoustic stimulation, has been proposed in the assessment of vestibulospinal pathways. AIM:To research the clinical utility of VEMP on multiple sclerosis (MS). SUBJECTS AND METHODS:Forty-four individuals were evaluated (30 normal state and 14 had MS). The acoustic stimuli were short tone burst (1 kHz, 118 dBNa, rise-fall 1 ms, plateau 2 ms) presented through a supra-aural earphone. The stimulation rate was 5 stimuli per second. RESULTS:All the healthy subjects showed a normal VEMP response. In the MS group, abnormal VEMP was recorded among 92.8% of patients and normal in just one case. The P13-N23 increased of prolongation which was the most frequently alteration (57.1%), followed by absence of response among four (28.5%) cases. CONCLUSION:VEMP was considered a good method of diagnostic support of vestibulospinal tract in cases of MS.
