Abstract

OBJECTIVE

To compare the canalith repositioning procedure (CRP) with a sham maneuver for the treatment of benign paroxysmal positional vertigo.

PATIENTS AND METHODS

We recruited 50 patients with a history of positional vertigo and unilateral positional nystagmus on physical examination (Dix-Hallpike maneuver). Patients were randomized to either the CRP (n = 24) or a sham maneuver (n = 26). Measured outcomes included resolution of vertigo and positional nystagmus at follow-up examination.

RESULTS

The mean duration of follow-up was 10 days for both groups. Resolution of symptoms was reported by 12 (50%) of the 24 patients in the CRP group and by 5 (19%) of the 26 patients in the sham group (P = .02). The results of the Dix-Hallpike maneuver were negative for positional nystagmus in 16 (67%) of 24 patients in the CRP group and in 10 (38%) of 26 patients in the sham group (P = .046).

CONCLUSION

The CRP is effective treatment of benign paroxysmal positional vertigo, and this procedure can be performed by general internists on outpatients with this disorder.

摘要

目的

比较耳石复位法（CRP）与模拟操作治疗良性阵发性位置性眩晕的效果。

患者与方法

我们招募了50例有位置性眩晕病史且体格检查（Dix-Hallpike试验）显示单侧位置性眼球震颤的患者。患者被随机分为CRP组（n = 24）或模拟操作组（n = 26）。测量的结果包括随访检查时眩晕和位置性眼球震颤的消失情况。

结果

两组的平均随访时间均为10天。CRP组24例患者中有12例（50%）报告症状消失，模拟操作组26例患者中有5例（19%）报告症状消失（P = .02）。CRP组24例患者中有16例（67%）Dix-Hallpike试验结果显示位置性眼球震颤为阴性，模拟操作组26例患者中有10例（38%）为阴性（P = .046）。
