Correlation between VEMP (Vestibular Evoked Myogenic Potentials) and Vestibular Ratio of Posturography in Patients with Vertigo

ABSTRACT

OBJECTIVE: To find out whether there is correlation between result of VEMP and vestibular ratio of posturography, and also to investigate if VEMP can show diagnostic efficiency in patients with vertigo. METHOD: Thirty-two patients whose BAEP test showed normal latency were included after patients whose somatosensory ratio and visual ratio from posturography showed abnormality were excluded. Ten healthy participants were set up as control group. We made comparison between P13 latency in VEMP and vestibular ratio posturography among these participants. RESULTS: Among the participants 47% showed normal P13 latency, and 53% showed abnormal P13 latency. In normal P13 latency group, 86.7% of patients showed normal vestibular ratio, and in abnormal P13 latency group, 70.6% of patients showed abnormal vestibular ratio. CONCLUSION: VEMP showed high correlation between vestibular ratio of posturography. VEMP can be used in screening test and clinically complementary diagnostic method of vestibular function test for patients with vertigo.
