目的:比较不同干预策略处理良性阵发性位置性眩晕（benign paroxysmal positional vertigo， BPPV）复位成功后残余症状的临床疗效。方法:采用平行、随机对照试验设计，2019年1—7月期间复旦大学附属眼耳鼻喉科医院收治的129例BPPV复位后有残余症状的患者在线完全随机化分至前庭康复组、倍他司汀组及对照组（空白），每组43例。前庭康复组接受为期4周的康复训练；倍他司汀组口服甲磺酸倍他司汀（12 mg/次，每日3次）4周；对照组无特殊处理。入组后4周、8周时随访，主要结局指标为日常活动与社会参与功能，采用前庭活动与参与量表（vestibular activities and participation measure，VAP）测量，次要指标为基于感觉统合试验（sensory organization test， SOT）的平衡功能以及残余症状的持续天数。采用STATA15.0软件进行统计学分析。结果:三组患者VAP量表得分随时间推移均呈下降趋势，但前庭康复组下降幅度更为显著。分组比较，前庭康复组与对照组差异有统计学意义（n B=-3.88，χn 2=18.29，n P0.05）；前庭康复组和倍他司汀组残余症状持续时间的中位数均为14 d，对照组为19 d，三组间差异无统计学意义［n Log-rank （n Mantel-Cox）n test；χn 2=1.82，n df=2，n P=0.40］。n 结论:前庭康复可以显著改善BPPV复位后残余症状患者的日常活动与社会参与功能，对缩短残余症状持续时间和促进平衡功能恢复的效果尚不确定。“,”Objective:To compare the effects of different intervention strategies for the management of residual dizziness following successful canalith repositioning procedure (CRP) in patients with benign paroxysmal positional vertigo (BPPV).Methods:A total of 129 BPPV patients with residual dizziness following successful CRP were recruited during January 2019 and July 2019. They were randomly assigned into three groups with 43 cases in each group: the vestibular rehabilitation group received rehabilitation training for four weeks; betahistine group was given orally 12 mg betahistine three times a day for four weeks; and the control group had no specific treatment. The primary outcomes were daily activities and social participation assessed by the Vestibular Activities and Participation measure (VAP). Secondary outcomes includedbalance function assessed by sensory organization test (SOT) and the duration of residual symptoms. Stata15.0 software was used for statistical analysis.Results:The scores of VAP in the three groups decreased over time, but a more significant decrease was found in vestibular rehabilitation group. Further paired comparison showed that the difference between the vestibular rehabilitation group and the control group was of statistical significance (n B=-3.88, χn 2=18.29, n P0.05). The median duration of residual dizziness for both vestibular rehabilitation and betahistine groups was 14 days, while that of control group was 19 days, with no significant difference between three groups[n Log-rank (n Mantel-Cox) test; χn 2=1.82, n df=2, n P=0.40].n Conclusion:Vestibular rehabilitation can significantly improve the daily activities and social participation function in BPPV patients with residual symptoms following successful CRP, but its effects on shortening the duration of residual symptoms and promoting the recovery of balance function remain uncertain.
