[The head-thrust test (HTT): physiopathological considerations and its clinical use in daily practice].
The basis of the head-thrust test is that when a head thrust is made in the horizontal plane, the ipsilateral semicircular channel (SCC) shows gaze stabilization because the homolateral SCC is completely inhibited. This test was studied by electronystagmography and the main parameters, the amplitude and latency of the compensatory ocular movements, were analyzed. The sensitivity, specificity, and positive and negative predictive value of this test were estimated in a series of 22 patients. The values were, respectively, 54, 100, 100 and 68%.
