INTRODUCTION
Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular dysfunction.
OBJECTIVE
To assess whether the performance of the Dix-Hallpike maneuver after the Epley positioning maneuver has prognostic value in the evolution of unilateral ductolithiasis of posterior semicircular canal.
METHODS
A prospective cohort study in monitored patients at otoneurology ambulatory with a diagnosis of BPPV; they were submitted to the therapeutic maneuver and then to a retest in order to evaluate the treatment effectiveness; all cases were reassessed one week later and the retest prognostic value was evaluated.
RESULTS
A sample of 64 patients which 47 belonging to negative retest group and 17 belonging to positive retest. Performed the maneuver in all patients, the retest presented 51.85% sensitivity, 91.89% specificity, 82.35% positive predictive value and 72.34% negative predictive value.
CONCLUSION
The study shows that doing the retest after repositioning maneuver of particles in BPPV is effectual, since it has high specificity.
简介
良性阵发性位置性眩晕（BPPV）是外周前庭功能障碍最常见的原因。
目的
评估 Epley 定位手法后 Dix-Hallpike 手法的表现对后半规管单侧管结石症演变的预后价值。
方法
一项前瞻性队列研究，监测在耳神经科门诊诊断为 BPPV 的患者；他们接受了治疗性手法，然后进行了复测，以评估治疗效果；所有病例均在一周后进行了重新评估，并评估了复测的预后价值。
结果
共有 64 名患者，其中 47 名患者的复测结果为阴性，17 名患者的复测结果为阳性。所有患者均进行了该手法，复测的敏感性为 51.85%，特异性为 91.89%，阳性预测值为 82.35%，阴性预测值为 72.34%。
结论
该研究表明，在 BPPV 中重新定位颗粒后进行复测是有效的，因为它具有很高的特异性。
