In 108 patients referred for caloric testing, head-shaking nystagmus (HSN) was noted in 37 electronystagmography (ENG) recordings. A canal paresis was found in 31 patients and a sensorineural or mixed hearing loss in one or both ears was found in 45 patients. Both HSN and canal paresis were insensitive predictors of either hearing loss or of each other. HSN was less sensitive as well as less specific than canal paresis for hearing loss. These data suggest that HSN is not as powerful a test as canal paresis in detecting lesions of the 8th nerve.
在108例接受冷热试验的患者中，37例眼震电图（ENG）记录发现有摇头性眼震（HSN）。31例患者存在半规管麻痹，45例患者一侧或双侧耳朵存在感音神经性或混合性听力损失。HSN和半规管麻痹对于听力损失或彼此而言都是不敏感的预测指标。对于听力损失，HSN的敏感性和特异性均低于半规管麻痹。这些数据表明，在检测第八对脑神经病变方面，HSN不如半规管麻痹检测能力强。
