To evaluate the efficacy of automatic benign paroxysmal positional vertigo (BPPV) diagnosis and treatment system for BPPV compared with the manual repositioning group.
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.
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.
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.
评估自动良性阵发性位置性眩晕（BPPV）诊断和治疗系统对 BPPV 的疗效，与手动复位组进行比较。
纳入 2018 年 8 月至 2019 年 7 月在浙江大学医院诊断为特发性 BPPV 的 230 例患者。其中，后半规管 BPPV（pc-BPPV）患者 150 例，水平半规管 BPPV（hc-BPPV）患者 53 例，水平半规管结石（hc-BPPV-cu）患者 27 例，随机采用 BPPV 诊断和治疗系统（实验组）或手动复位（对照组）进行治疗。主要观察指标为首次治疗后第 3、7、14 和 28 天 Dix-Hallpike 和 Roll 试验时眩晕和眼震的缓解情况，评估治疗效果。
BPPV 诊断和治疗系统治疗后 3 天和 7 天随访时，79%、91%的患者眩晕和眼震完全缓解，实验组有效率明显高于对照组，差异有统计学意义（P<.05）。第 14 天，实验组（96%）的有效率略高于对照组（91%），但两组间差异无统计学意义。首次治疗后第 28 天，实验组和对照组的有效率均为 100%。pc-BPPV（首次、二次、三次治疗）、hc-BPPV（首次、二次、三次治疗）、hc-BPPV-cu（首次、二次治疗）的实验组复位效率均高于对照组，pc-BPPV 二次复位实验组明显高于对照组（96%比 84%；P<.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。
BPPV 诊断和治疗系统治疗 BPPV 有效，有效率优于手动复位，对患者安全且易于操作。
