体位限制对手法复位后良性阵发性位置性眩晕的疗效观察

目的 探讨手法复位后体位限制对良性阵发性位置性眩晕(BPPV)患者的疗效。 方法 2015年12月至2016年6月共收治BPPV患者210例,随机分为手法复位后联合体位限制组(观察组)105例和单纯手法复位组(对照组)105例,其中后半规管BPPV(PSC-BPPV)患者两组各70例,向地性水平半规管BPPV(HSC-BPPV)患者两组各25例,背地性HSC-BPPV患者两组各10例。 结果 PSC-BPPV两组短期7 d和3个月疗效差异均无统计学意义(P=0.515, P=0.967); 向地性HSC-BPPV和背地性HSC-BPPV患者两组短期7 d疗效差异均有统计学意义(P=0.030, P=0.040),长期疗效评价无统计学意义(P=0.972)。 结论 PSC-BPPV患者行手法复位后可不予体位限制,HSC-BPPV患者手法复位后需要行体位限制,待患者无任何症状后可以自由体位。

Curative effect of postural restriction on benign paroxysmal positional vertigo after manual reduction.

Objective To examine the effect of postural restriction on patients with benign paroxysmal positional vertigo(BPPV)after manual reduction. Methods A total of 210 cases of BPPV including 140 with posterior semicircular canal(PSC)-BPPV and 70 with horizontal semicircular canal(HSC)-BPPV(50 HSC-BPPV and 20 apogeotropic HSC-BPPV)were randomly divided into a combined position restriction group(observation group)and a control group. Results In patients with PSC-BPPV, there was no significant short-term(7 days)or long-term(3 months)difference in curative effect between the two groups(P=0.515, P=0.967). There was a statistically significant difference during short-term evaluation(P=0.030, P=0.040)but no significant difference(P=0.972)in the long-term curative effect between the HSC-BPPV and apogeotropic HSC-BPPV groups. Conclusion Postural restriction therapy is not needed in PSC-BPPV but should be used in HSC-BPPV until symptoms remit.
