| Popis: | OBJECTIVE: The goal of this study was to determine the sensitivity and specificity of some widely used, easily administered clinical tests. BACKGROUND: Simple tests of oculomotor function have become widely used for clinical screening of patients suspected of having vestibular disorders despite a paucity of evidence showing good statistical support for their use in this highly variable population. METHODS: Healthy controls with no history of otologic or neurologic disorders (n-291) were compared to patients with known vestibular disorders (n=62). All subjects performed passive and active head shaking, un-instrumented head impulse tests (HT) and video head impulse tests (vHIT) recorded with infrared video-oculography. RESULTS: For both passive and active head shaking, using presence/absence of vertigo and of nystagmus, sensitivity was low, < 0.40. Sensitivity of presence/absence of saccades on HT was even lower, < 0.15. On vHIT, gains were all approximately 1.0, so sensitivity was very low, approximately 0.15 to 0.35. Sensitivity and specificity for presence/absence of saccades were moderately poor, less than 0.70. CONCLUSIONS: None of these tests are adequate for screening patients in the out-patient clinic for vestibular disorders or for screening people in epidemiologic studies to determine the prevalence of vestibular disorders. |
