To assess the short-term efficacy of Semont maneuver for unilateral posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV).
The short-term efficacy of Semont maneuver was compared with a sham procedure in 128 patients with PC-BPPV by using a double-blinded prospective randomized controlled trial in the setting of a neurologic outpatient clinic in China. Analysis was based on the symptomatic status and the Dix-Hallpike maneuver on the fourth day. At this time, patients in both groups with a still positive Dix-Hallpike test were treated with Semont maneuver, and outcome was again assessed on the seventh day.
On the fourth day, 55 (84.62%) of 65 patients in the treatment group showed complete resolution of symptoms compared with 9 (14.29%) of 63 patients in the control group. (p < 0.001) 59 (90.77%) of 65 and 52 (82.54%) of 63 patients reported resolution of symptoms in the treatment and original sham group, respectively (p = 0.17).
Semont maneuver is shown to resolve PC-BPPV effectively, and patients should receive Semont maneuver once the PC-BPPV diagnosis was confirmed.
评估 Semont 手法治疗单侧后半规管良性阵发性位置性眩晕（PC-BPPV）的短期疗效。
在中国一家神经病学门诊的背景下，采用双盲前瞻性随机对照试验，比较 Semont 手法与假手术治疗 128 例 PC-BPPV 患者的短期疗效。分析基于症状状态和第 4 天的 Dix-Hallpike 试验。此时，两组中 Dix-Hallpike 试验仍为阳性的患者均接受 Semont 手法治疗，第 7 天再次评估疗效。
第 4 天，治疗组 65 例患者中 55 例（84.62%）症状完全缓解，而对照组 63 例患者中仅 9 例（14.29%）（p<0.001）。治疗组和原始假手术组分别有 59 例（90.77%）和 52 例（82.54%）患者报告症状缓解（p=0.17）。
Semont 手法可有效治疗 PC-BPPV，一旦确诊，患者应接受 Semont 手法治疗。
