Comparison of the Vestibular Evoked Myogenic Potential and the Blink Reflex in Cerebellar and Brainstem Infarction Patients

Objective: This study investigated whether the blink reflex could be substituted for vestibular evoked myogenic potential (VEMP), which has some limitations use in stroke patients.Methods: Thirty-four patients with cerebellar or brainstem ischemic underwent VEMP and testing. We compared P13 latency of R1, R2, R2’ patients. Statistical analysis was conducted using Fisher exact test independent t-test, a p-value < 0.05 indicating statistical significance.Results: In 29 patients, excluding those bilateral lesions, did not show statistically significant relationship (p = 0.2701). all 34 participating study, including mean showed difference 0.0081) according to presence normal abnormal VEMP. Conclusion: passes through more neural pathways polysynaptic than R1 R2; therefore, it prominent between groups.
