Vertigo is a complex symptom which imposes diagnostic and treatment challenges. Laboratory evaluation of vertigo includes video-nystagmography (VNG) and computerized dynamic posturography (CDP) for the evaluation of different aspects of this complaint. There are vague indications for each test and potential disagreements between them. The aim of this study is to examine the association between the test results of the VNG and sensory organization test (SOT) of CDP in patients referred for both vestibular tests.
Retrospective data regarding 56 patients age 17-82 years were collected. Patients suffered vestibular complaints and were referred for VNG and CDP evaluation on the same day. The level of agreement between VNG (including caloric test) and the vestibular input of the SOT for each patient was calculated.
Among the study group, 10 showed abnormal caloric test results, of which 3 (5.4%) had normal vestibular input in the SOT, and 7 (12.5%) had impaired input (p = 0.724). Spontaneous nystagmus was recorded in 13 patients by VNG, of which 2(3.6%) had normal vestibular input and 11(19.6%) had impaired vestibular input (p = 0.056).
This study shows no statistically significant association between the VNG test and SOT test results. Our results emphasize the difference between the tested aspects in each laboratory test, and the need to define specific indications for each of them. There is a marginally significant association between impaired vestibular input and spontaneous nystagmus, demonstrating the non-localizing nature of this sign.
眩晕是一种复杂的症状，给诊断和治疗带来了挑战。眩晕的实验室评估包括视频眼震图（VNG）和计算机动态姿势描记术（CDP），以评估该症状的不同方面。每项测试的适应证都不明确，并且它们之间可能存在分歧。本研究的目的是检查 VNG 和 CDP 的感觉组织测试（SOT）的测试结果在因前庭问题而接受两种测试的患者之间的关联。
回顾性收集了 56 名 17-82 岁患者的数据。患者有前庭主诉，并在同一天接受 VNG 和 CDP 评估。计算了每位患者的 VNG（包括冷热测试）和 SOT 的前庭输入之间的一致性水平。
在研究组中，10 例冷热测试结果异常，其中 3 例（5.4％）SOT 的前庭输入正常，7 例（12.5％）输入受损（p = 0.724）。VNG 记录了 13 例自发性眼震，其中 2 例（3.6％）前庭输入正常，11 例（19.6％）前庭输入受损（p = 0.056）。
本研究表明 VNG 测试与 SOT 测试结果之间无统计学显著关联。我们的结果强调了每个实验室测试中所测方面的差异，以及为每个测试确定具体适应证的必要性。受损的前庭输入与自发性眼震之间存在边际显著关联，表明该体征无定位意义。
