Vestibular tests were performed in more than 600 otoneuological patients. The data analysed included the otoneurological history, audiograms, observation of spontaneous nystagmus, caloric and swing tests, and recording by electronystagmography. The tracings were subjected to summation of the amplitudes of the slow-phase nystagmus and classification of the recording as peripheral (small amplitude, high frequency) or central (dysrhythmia with bouts of high-frequency nystagmus). The correlations between spontaneous nystagmus and directional preponderance in caloric and rotation tests are complex, and our results show that an isolated abnormality has little significance. The expected correlation between hearing loss and unilateral caloric paresis was confirmed. Other lesions, such as peripheral or central ENG tracings and reduced vestibular reaction, did not correlate with any other pathological finding. Directional preponderance and spontaneous nystagmus were significantly more frequent in patients with unilateral caloric paresis than in those with a symmetrical response. The incidence of a peripheral type of ENG tracing, hearing loss and unilateral paresis increased with the age of the patients. Reduced vestibular response, a central type of tracing and directional preponderance did not correlate with age. The well-known variability of the subjective threshold of vertiginous sensations was confirmed by the results in patients with no vertigo, and deserves more attention.
对600多名耳神经科患者进行了前庭测试。分析的数据包括耳神经科病史、听力图、自发性眼球震颤观察、冷热试验和摆动试验，以及通过眼震电图进行记录。对记录进行慢相眼球震颤振幅总和，并将记录分类为外周性（小振幅、高频）或中枢性（伴有高频眼球震颤发作的节律异常）。冷热试验和旋转试验中自发性眼球震颤与优势偏向之间的相关性很复杂，我们的结果表明，孤立的异常意义不大。听力损失与单侧冷热麻痹之间的预期相关性得到了证实。其他病变，如外周或中枢性眼震电图记录以及前庭反应减弱，与任何其他病理发现均无相关性。单侧冷热麻痹患者的优势偏向和自发性眼球震颤明显比反应对称的患者更常见。外周型眼震电图记录、听力损失和单侧麻痹的发生率随患者年龄增加而升高。前庭反应减弱、中枢型记录和优势偏向与年龄无关。无眩晕患者的结果证实了眩晕主观阈值众所周知的变异性，这值得更多关注。
