Abstract：
OBJECTIVE: To evaluate the efficacy of automatic benign paroxysmal positional vertigo (BPPV) diagnosis and treatment system for BPPV compared with the manual repositioning group.
METHODS: Two hundred thirty patients diagnosed as idiopathic BPPV who were admitted from August 2018 to July 2019 in Zhejiang Hospital were included. Among them, 150 patients of posterior semicircular canal BPPV(pc-BPPV), 53 patients of horizontal semicircular canal BPPV(hc-BPPV), and 27 patients of horizontal semicircular canal calculus (hc-BPPV-cu) were randomly treated with BPPV diagnosis and treatment system(the experimental group) or manual repositioning (the control group). Resolution of vertigo and nystagmus on the Dix-Hallpike and Roll test on day 3,day 7,day 14 and day 28 follow-up after first treatment was the main outcome measure to assess the efficacy of treatment.
RESULTS: At 3-day and 7-day follow-up after treatment with BPPV diagnosis and treatment system, 79%, 91%had complete resolution of vertigo and nystagmus, the effective rate in the experimental group were significantly higher than those in the control group, the differences were statistically significant(P < .05). On day 14, the effective rate in the experimental group (96%) was slightly higher than that in the control group(91%), but there was no significant difference between the two groups. And at 28-day after the first treatment, the effective rate was 100% in the experimental group and the control group. The repositioning efficiency of pc-BPPV (the first, second, third treatment), hc-BPPV (the first, second, third treatment), hc-BPPV-cu(the first, second treatment) in the experimental group were higher than the control group, and the secondary reposition of pc-BPPV in the experimental group was significantly higher than the control group(96%vs.84%; P < .05). While for the hc-BPPV-cu patients, the effective rate of the third treatment in the experimental group was slightly lower than that of the control group, but the differences were not statistically significant.
CONCLUSIONS: BPPV diagnosis and treatment system is effective for the treatment of BPPV, with a better effective rate than those treated with manual maneuver, and is safe and easy to perform on patients.

摘要：
目的：评估自动良性阵发性位置性眩晕（BPPV）诊断和治疗系统与手动复位组的疗效。
方法：纳入浙江医院2018年8月至2019年7月收治的诊断为特发性BPPV的患者230例。其中,150例后半规管BPPV（pc-BPPV），53例水平半规管BPPV（hc-BPPV），对27例水平半规管结石(hc-BPPV-cu)患者随机采用BPPV诊疗系统(实验组)或手动复位(对照组)进行治疗。首次治疗后第3天，第7天，第14天和第28天随访的Dix-Hallpike和Roll测试中的眩晕和眼球震颤的消退是评估治疗效果的主要结果指标。
结果：在用BPPV诊断和治疗系统治疗后的3天和7天随访时，79%,91%的眩晕和眼球震颤完全缓解，实验组有效率明显高于对照组,差异有统计学意义(P<0.05)。第14天,实验组有效率(96%)略高于对照组(91%),但两组间差异无统计学意义。在第一次治疗后的28天，实验组和对照组有效率均为100%。PC-BPPV的重定位效率(第一，第二,第三次治疗)，hc-BPPV(第一个，第二,第三次治疗)，hc-BPPV-cu(第一个，第二次治疗)实验组高于对照组,实验组PC-BPPV的二次复位率明显高于对照组（96％vs.84％；P<0.05）。而对于hc-BPPV-cu患者，实验组第三次治疗的有效率略低于对照组,但差异无统计学意义。
结论：BPPV诊疗系统是治疗BPPV的有效方法，具有比手动操作治疗更好的有效率，并且是安全和易于执行的患者。
