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,对照组给予假复位治疗。结果复位组43例,对照组45例,第4天随访时复位组和对照组的治疗成功率分别为86.05%(37/43)和8.89%(4/45),两者差异显著(χ2=49.56,P<0.01);第7天时,两者的成功率分别为95.35%(41/43)和17.78%(8/45),仍差异显著(χ2=50.52,P<0.01)。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。
Objective To evaluate the role of PRM in the treatment of semicircular canal benign paroxysmal positional vertigo (PC-BPPV). Methods The patients with PC-BPPV were randomly divided into two groups. The patients in the reset group were treated with PRM and the patients in the control group were given pseudo-reset therapy. Results In the control group, there were 43 cases in the control group and 45 cases in the control group. The success rates of the treatment group and the control group were 86.05% (37/43) and 8.89% (4/45) respectively at the 4th day of follow-up. The difference was significant (χ2 = 49.56, P <0.01). On the 7th day, the success rates were 95.35% (41/43) and 17.78% (8/45) respectively, with significant difference (χ2 = 50.52, P <0.01). Conclusions The efficacy of PRM is significantly higher than that of the control group. All patients with definite diagnosis of PC-BPPV should be treated with PRM.
