摘　　要：目的探讨仰头试验在累及后半规管的良性阵发性位置性眩晕(benign paroxysmal positional vertigo of posterior semicircular canal,PC-BPPV)中的诊断价值。方法我们回顾性纳入了220例就诊于嘉兴市第二医院神经内科的单侧PC-BPPV患者的临床资料,所有患者先行仰头试验,然后行Dix-Hallpike试验,并研究仰头试验诱发眩晕患者的临床特征。结果133例(60.5%)患者在仰头试验期间诱发了PC-BPPV典型的上跳扭转眼震,Dix-Hallpike试验期间,诱发的上跳眼球震颤的最大慢相角速度(SPV)高于仰头试验诱发的SPV值,其诱发潜伏期及持续时间都与仰头试验有显著性差异(P<0.001)。结论仰头试验对诊断PC-BPPV有一定的参考价值,对诊断PCBPPV有效,仰头试验诱发眼震强度较悬头位小,自主神经症状轻,鉴于其简单性,仰头试验可以在Dix-Hallpike操作之前进行。Objective To investigate the diagnostic value of lean test in Benign paroxysmal positional vertigo of posterior semicircular canal(PC-BPPV).Methods We retrospectively included the clinical data of 220 patients with unilateral PC-BPPV who were admitted to the Department of Neurology,Jiaxing Second Hospital.All patients underwent lean test first,and then Dix-Hallpike test was performed to study the clinical characteristics of patients with vertigo induced by lean test.Results 133(60.5%)patients induced PC-BPPV typical upbeat torsional nystagmus during the lean test.During the Dix-Hallpike test,the maximum slow phase angular velocity(SPV)of the induced upbeat nystagmus was higher than the SPV value induced by the lean test,and the latency and duration of the induced nystagmus were significantly different from the lean test(P<0.001).Conclusion The lean test has a certain reference value for the diagnosis of PCBPPV.It is effective for the diagnosis of PC-BPPV.The lean test induces a small nystagmus and mild autonomic symptoms compare to suspension position.In view of its simplicity,the lean test can be performed before the Dix-Hallpike operation.
