The aim of this study was to investigate the diagnostic capacity of three different rotatory tests, and to investigate the clinical effectiveness of the caloric, rotatory, and vestibular evoked myogenic potential (VEMP) test.
Several rotatory tests--sinusoidal harmonic acceleration test (SHAT), pseudorandom rotation test (PRRT), velocity step test (VST)--and a caloric and a VEMP test, were given to 77 patients (mean age 52 years) with a unilateral peripheral vestibular pathology, and 80 control subjects (mean age 48 years).
For the rotatory test, the highest diagnostic capacity was obtained with the 0.01 Hz SHAT frequency, followed by 0.1 and 0.05 Hz. A higher diagnostic accuracy was reached for the caloric and VEMP test. The caloric test demonstrated high sensitivity and specificity values, but the 0.01 Hz SHAT rotation appeared more sensitive, and the VEMP more specific, than the caloric test.
A selection of the 0.01, 0.05, and 0.1 Hz SHAT rotations is suggested as the most ideal rotatory test protocol, and a combination of rotatory, caloric, and VEMP testing will result in a more complete examination of our vestibular system.
本研究旨在探讨三种不同旋转测试的诊断能力，并研究冷热、旋转和前庭诱发肌源性电位（VEMP）测试的临床效果。
对 77 例单侧周围前庭病变患者（平均年龄 52 岁）和 80 例对照受试者（平均年龄 48 岁）进行了正弦谐波加速测试（SHAT）、伪随机旋转测试（PRRT）、速度阶跃测试（VST）等几种旋转测试以及冷热和 VEMP 测试。
对于旋转测试，0.01 Hz SHAT 频率获得了最高的诊断能力，其次是 0.1 和 0.05 Hz。冷热和 VEMP 测试的诊断准确性更高。冷热测试显示出高的敏感性和特异性值，但 0.01 Hz SHAT 旋转比冷热测试更敏感，而 VEMP 更具特异性。
建议选择 0.01、0.05 和 0.1 Hz 的 SHAT 旋转作为最理想的旋转测试方案，旋转、冷热和 VEMP 测试的组合将使我们的前庭系统得到更全面的检查。
