Evaluación de la función vestibular angular: Prueba de impulso cefálico multiaxial a ojo desnudo

Abstract: La prueba de impulso cefálico consiste en un examen rápido, sencillo para evaluar la función vestibular angular. Clásicamente se utiliza para el canal horizontal, pero puede implementarse para evaluar los canales semicirculares anteriores y posteriores. Objetivo: Explorar la sensibilidad y especificidad de esta prueba para los canales verticales a ojo desnudo en nuestro medio, en relación a la prueba calórica. Material y método: Estudio prospectivo de evaluación de test diagnóstico. Se realizó prueba de impuls… Show more

“…The sensitivity and specificity of the Head Impulse Test found in this study are in agreement with the reported average from all papers in the literature (2,4–8) (see Supplemental content 5, supplementary appendix, http://links.lww.com/MAO/B363). Except for the findings of MacDougall et al (15), where 0.7 was set as the cut-off between a normal VOR and a pathological VOR, no other author has established a VOR gain cut-off to assess normalcy.…”

“…When performed by experienced clinicians, this clinical test has low sensitivity and high specificity. Low test sensitivity derives from the difficulty of detecting the small refixation saccades (2)(3)(4)(5)(6)(7)(8)(9). Sensitivity and specificity differ based on the experience of the clinician; when performed by experts, this test is usually less sensitive but more specific (4).…”
