目的：良性阵发性位置性眩晕（BPPV）患者经常出现姿势不稳定以及短暂的眩晕发作。本研究的目的是确定通过使用耳石重新定位治疗成功解决阵发性眩晕是否会伴随着姿势稳定性的改善。研究设计：前瞻性临床研究。地点：一所大学的门诊三级护理机构。患者：33 名被诊断为单侧影响后耳管的耳管结石型 BPPV 的患者。所有患者治疗后位置性眩晕均得到完全缓解。热量或转椅测试结果异常的患者被排除在研究之外。 干预：通过耳石复位治疗后管BPPV。主要指标：治疗前和治疗后1至2周通过计算机动态姿势描记法评估姿势稳定性。使用了六种不同的子测试。 结果：在治疗前，通过计算机动态姿势描记术测量，大量患者的稳定性异常。治疗后，在不同分项测试中获得正常结果的受试者数量显着增加；然而，并非所有患者都具有正常的姿势稳定性。年轻受试者更有可能表现出更好的稳定性。结论：使用耳石重新定位治疗 BPPV 可以改善 BPPV 患者的姿势稳定性。然而，并非所有患者在治疗后都具有正常的稳定性，平衡问题的评估和治疗可能是必要的。
Objective: Patients with benign paroxysmal positional vertigo (BPPV) often experience postural instability as well as brief episodes of vertigo. The purpose of this study was to determine whether successful resolution of the episodic vertigo, through use of the canalith repositioning treatment, would be accompanied by improvement in postural stability.Study Design: Prospective clinical study.Setting: Outpatient tertiary care facility in a university.Patients: Thirty-three patients with a diagnosis of the canalithiasis form of BPPV affecting the posterior canal unilaterally. All patients had complete remission of the positional vertigo after treatment. Patients with abnormal caloric or rotary chair test results were excluded from the study.Intervention: The posterior canal BPPV was treated by the canalith repositioning treatment.Main Outcome Measures: Postural stability was assessed by computerized dynamic posturography before and 1 to 2 weeks after treatment. Six different subtests were used.Results: A significant number of patients had abnormal stability, as measured with computerized dynamic posturography, before treatment. After treatment there was a significant increase in the number of subjects with normal results on the different subtests; however, not all patients had normal postural stability. Younger subjects were more likely to show improved stability.Conclusions: Treatment of BPPV using the canalith repositioning treatment results in improved postural stability in patients with BPPV. Not all patients have normal stability after treatment, however, and assessment and treatment of the balance problems may be necessary.
