Introduction: Traditionally, the assessment of vestibular function is based on the caloric test. This procedure assesses mainly the horizontal semicircular canal function, leaving other vestibular structures aside, such as the utricle-saccule complex. Aim: To assess the diagnostic performance low complexity tests to compensate for these issues. Material and methods: 34 patients with indication for vestibular assessment wererecruited. In addition to traditional testing (caloric test and postural provocation ma-neuvers), the mentioned Subjective Visual Vertical and Head Impulse tests were appliedalongside the Dizziness Handicap Inventory for vestibular symptoms.Results: Considering caloric testing and Dix-Hallpike maneuvers as gold standard,50% of the sample presented an objective cause of their symptomatology. When including the new test, this value increases to 85%. A discrepancy analysis was conducted on the group with normal traditional tests and abnormal new tests. 100% of this group showed symptom scores above pathological levels. Furthermore, there was a strong relationship between deviation on the Visual Vertical test and symptomatology (r =0,79; p =0,002). Conclusion: The discrepancy analysis suggests that the new tests are reliable in determining pathology in this study. If these test are included to traditional testing,diagnostic performance may increase up to 35%.
