摘要:
Correlations among different equilibrium function tests were investigated in 130 patients with Ménière’s disease. The tests consisted of 22 different items, and the possible results could be put into a total of 49 categories. Using a factor analytic method, results falling in the positive area of the 1st axis indicate normality of the vestibular system, and results in the negative area, indicate an abnormality of the vestibular system. On the 2nd axis, the negative direction indicates an abnormality of the vestibulo-spinal system, and the positive direction an abnormality of the vestibulo-ocular system. In this paper, relationships among sex, age, the Cornell medical index results, and the time between the vertigo attack and testing, as well as between the onset of the disease and testing, are shown on a two-dimensional pl
