This study was designed to assess the utility of otolith-ocular reflex testing in patients with complete unilateral peripheral vestibular deficits. Ten subjects were given a clinical vestibular test battery (ENG & vertical rotation) and research oriented tests of otolith function including dynamic posturography with head tilt and earth-horizontal axis rotation with otolith-visual interactions. Clinical tests confirmed the presence of a vestibular deficit and the side of the lesion. The results suggested the following: posturography during head tilt is not a reliable means of detecting unilateral peripheral vestibular dysfunction, while earth-horizontal axis rotation is a reliable means of assessing asymmetric otolith function. The Bias response during earth-horizontal axis rotation was significantly less during rotation ipsilateral to the lesioned ear compared to contralateral rotation while the Mod response was normal. The optokinetic test results in these subjects were normal while otolith-visual interactions were symmetrically reduced in these patients.
本研究旨在评估耳石-眼反射测试在完全性单侧外周前庭功能缺损患者中的效用。10名受试者接受了临床前庭测试组合（眼震电图和垂直旋转测试）以及针对耳石功能的研究性测试，包括头部倾斜动态姿势描记法以及耳石-视觉相互作用的地水平轴旋转测试。临床测试证实了前庭功能缺损的存在以及病变侧别。结果表明：头部倾斜时的姿势描记法并非检测单侧外周前庭功能障碍的可靠方法，而地水平轴旋转是评估不对称耳石功能的可靠方法。与对侧旋转相比，病变耳同侧旋转时地水平轴旋转过程中的偏差反应明显更小，而调制反应正常。这些受试者的视动测试结果正常，而这些患者的耳石-视觉相互作用对称降低。
