    [摘要] 目的 评价颗粒复位手法(PRM)在治疗后半规管良性发作性位置性眩晕(PC-BPPV)中的作用。 方法 将PC-BPPV患者随机分成2组，复位组给予PRM治疗加体位限制，对照组仅给予体位限制治疗。 结果 复位组32例，对照组31例，第4天随访时复位组和对照组的治疗成功率分别为 81.3%(26/32)和16.1%(5/31)，两者相差显著(c2=24.17，p<0.005)，第7天随访时，两者的成功率分别为93.8%(30/32) 和32.3%(10/31)，两者也相差显著(c2=23.10，p<0.005)。 结论 PRM疗效明显高于对照组，凡PC-BPPV诊断明确者均应给予PRM治疗。

    The efficacy of particle repositioning maneuver therapy for posterior semicircular canal benign paroxysmal positional vertigo

    [Abstract] Objective To assess the efficacy of particle repositioning maneuver(PRM) therapy for posterior semicircular canal benign paroxysmal positional vertigo(PC-BPPV). Methods Patients with unilateral PC-BPPV were randomly divided into 2 groups: repositioning group and control group, patients in repositioning group were received PRM and postural restriction therapy, patients in control group were only received postural restriction therapy. Results There were 32 patients in repositioning group and 31 patients in control group, The success rates in repositioning group and control group were 81.3%(26/32)and 16.1%(5/31) respectively in the fourth day, there was significant difference between the two rates(c2=24.17 ......
