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。
Objective To investigate the effect of postoperative posture reduction on patients with benign paroxysmal positional vertigo (BPPV). Methods A total of 210 patients with BPPV were admitted to our hospital from December 2015 to June 2016. They were randomly divided into two groups: 105 cases in combination with restriction group (observation group) and 105 cases in simple manipulation group (control group) PSC-BPPV), 70 cases in each group, 25 cases in each group with gemcitabine semicircular canalization BPPV (HSC-BPPV) and 10 cases in each group with cryptogenic HSC-BPPV. Results There was no significant difference between the two groups in PSC-BPPV on the 7th and 3rd months (P = 0.515, P = 0.967). The short-term effects on the 7th and the 3rd day in both the HSC-BPPV and the HSCTBP- (P = 0.030, P = 0.040). The long-term curative effect was not statistically significant (P = 0.972). Conclusions PSC-BPPV patients may not be placed postoperatively by manual reduction. Patients with HSC-BPPV need to have their posture restricted after reduction. After the patients have no symptoms, they can freely position themselves.
