This study was performed to determine the relative effectiveness of several passive head maneuvers for treating benign paroxysmal positional vertigo.
This prospective study used 87 subjects diagnosed by their physicians with unilateral benign paroxysmal positional vertigo of the posterior semicircular canal.
Subjects were randomly assigned to three treatment groups: modified Epley maneuver, modified Epley maneuver with augmented head rotations, and modified Semont maneuver. They were interviewed 1 week after receiving one maneuver. If subjects desired further treatment, they were treated again with the same maneuver, a methodology repeated until subjects desired no further treatment; they were telephoned 3 and 6 months after the last treatment.
The groups did not differ significantly, but subjects decreased significantly on vertigo intensity and frequency and improved significantly on independence in activities of daily living. Before treatment, tasks requiring pitch rotations of the head induced vertigo; common comorbid conditions were osteoporosis, cervical spine problems, and head trauma.
These data suggest that augmented head rotations are unnecessary and that the modified Epley and Semont maneuvers are equally effective in the remediation of vertigo in this population.
本研究旨在确定几种被动头部动作治疗良性阵发性位置性眩晕的相对有效性。
这项前瞻性研究纳入了87名经医生诊断为后半规管单侧良性阵发性位置性眩晕的受试者。
受试者被随机分为三个治疗组：改良Epley法、增加头部旋转的改良Epley法和改良Semont法。在接受一种动作治疗1周后对他们进行访谈。如果受试者希望进一步治疗，则再次用相同的动作进行治疗，该方法重复进行，直到受试者不再希望进一步治疗；在最后一次治疗后3个月和6个月给他们打电话。
各组之间无显著差异，但受试者的眩晕强度和频率显著降低，日常生活活动独立性显著改善。治疗前，需要头部俯仰旋转的任务会诱发眩晕；常见的合并症有骨质疏松症、颈椎问题和头部外伤。
这些数据表明增加头部旋转并无必要，改良Epley法和Semont法在改善该人群眩晕方面同样有效。
