To compare the effectiveness of the 'repositioning' Epley maneuver and the 'liberatory' Semont maneuver in the treatment of benign paroxysmal positional vertigo (BPPV) of the posterior semicircular canal, a prospective study was performed, with 3 months of followup. A consecutive sample of 100 patients was included in two groups (age-and-sex matched) with a similar number of patients with idiopathic BPPV in each group. Group I was treated using the 'repositioning' maneuver and group II, the 'liberatory' maneuver. At weeks 1, 4, and 12 during the study, the proportion of patients without positional nistagmus was identified, and patients gave an evaluation of their subjective improvement (as a percentage). When positional nystagmus was evident, the corresponding maneuver was used again. Sixty percent of the patients were without nystagmus after the single use of any of the maneuvers. At the end of the study, more than 90% of patients were without nystagmus, with a 90% median value of subjective improvement. Patients with idiopathic BPPV showed a similar response to treatment as patients with BPPV associated to other disorders. We conclude that both maneuvers are effective for the treatment of BPPV of the posterior semicircular canal.
为比较“复位性”埃普利手法和“解放性”塞蒙特手法治疗后半规管良性阵发性位置性眩晕（BPPV）的疗效，进行了一项前瞻性研究，并随访3个月。连续选取100例患者，分为两组（年龄和性别匹配），每组特发性BPPV患者数量相近。第一组采用“复位性”手法治疗，第二组采用“解放性”手法治疗。在研究期间的第1周、第4周和第12周，确定无位置性眼震的患者比例，患者对主观改善情况进行评估（以百分比表示）。当位置性眼震明显时，再次使用相应手法。单次使用任何一种手法后，60%的患者无眼震。研究结束时，超过90%的患者无眼震，主观改善的中位数为90%。特发性BPPV患者与其他疾病相关BPPV患者对治疗的反应相似。我们得出结论，两种手法均对后半规管BPPV有效。
