To observe the short-term efficacy of modified Semont maneuver for posterior canal benign paroxysmal positional vertigo (PC-BPPV)This was a prospective randomized controlled trial on 130 PC-BPPV patients. Subjects were randomized divided into two groups: modified Semont (65 patients),and Epley(65 patients).Each maneuver was repeated twice,and the presence of sequelae,nystagmus and vertigo on positional testing were evaluated 3rd day and 1 week after treatment.Five patients were lost to follow up (all five in the modified Semont group),and three patients failed to complete treatment (all three in the Epley group). The sequelae at the 3rd day and one week after modified Semont maneuver were 27 and 9,while 41 and 15 in Epley group. The efficacy rates at the 3rd day and one week after modified Semont maneuver were 91.7% and 98.3%,and 91.9% and 96.8% in Epley group retrospectively. The sequelae and short-term effective rate of patients in modified Semont group was no difference when compared with that in Epley group (>0.05).Modified Semont maneuver represents a simple rapid and effective approach to the treatment of posterior canal benign paroxysmal positional vertigo.
观察改良Semont法治疗后半规管良性阵发性位置性眩晕（PC-BPPV）的短期疗效
这是一项针对130例PC-BPPV患者的前瞻性随机对照试验。受试者被随机分为两组：改良Semont组（65例患者）和Epley组（65例患者）。每种手法重复两次，并在治疗后第3天和1周评估位置试验时后遗症、眼震和眩晕的情况。5例患者失访（均在改良Semont组），3例患者未完成治疗（均在Epley组）。改良Semont手法后第3天和1周的后遗症分别为27例和9例，Epley组分别为41例和15例。回顾性分析改良Semont手法后第3天和1周的有效率分别为91.7%和98.3%，Epley组分别为91.9%和96.8%。改良Semont组患者的后遗症和短期有效率与Epley组相比无差异（>0.05）。改良Semont手法是治疗后半规管良性阵发性位置性眩晕的一种简单、快速且有效的方法。
