: Persistent postural-perceptual dizziness (PPPD) represents an important category of vertigo. Medical treatment and psychotherapy provide convenient control of symptoms. However, these management strategies can have inconvenient side effects and short-term relief, respectively. Vestibular rehabilitation therapy (VRT) is a self-conducted habituation program that can be personalized to the subject's needs to give adequate symptom relief without side effects. The present study aims to test the effect of VRT on patients with PPPD.
: Participants were diagnosed as having PPPD by the exclusion of organic vestibular lesions. The study involved 2 groups with PPPD: Group I, treated with the VRT, and Group II, treated with the VRT plus placebo. The Dizziness Handicap Inventory (DHI), a self-assessment scale, was used to evaluate the VRT outcomes.
: There was a significant decrease in functional, physical, and total scores on the DHI in both groups after VRT. Adding the placebo did not have supplementary outcomes. The patients who did not benefit from the VRT had a significantly longer duration of PPPD, more complex aggravating factors, more composite VRT exercises, and a higher DHI score than the patients who benefited from VRT.
: Customized VRT adequately reduced symptoms and improved quality of life in subjects with PPPD.
持续性姿势-知觉性头晕（PPPD）是眩晕的一个重要类型。药物治疗和心理治疗能方便地控制症状。然而，这些治疗策略分别可能有不便的副作用和只能带来短期缓解。前庭康复治疗（VRT）是一种可自行进行的习服训练项目，可根据个体需求进行个性化定制，以充分缓解症状且无副作用。本研究旨在测试VRT对PPPD患者的疗效。
通过排除器质性前庭病变将参与者诊断为PPPD。该研究纳入两组PPPD患者：第一组接受VRT治疗，第二组接受VRT加安慰剂治疗。采用自我评估量表眩晕残障量表（DHI）来评估VRT的治疗效果。
两组患者在VRT治疗后，DHI的功能、身体和总分均显著降低。添加安慰剂并无额外效果。与从VRT治疗中获益的患者相比，未从VRT治疗中获益的患者PPPD病程显著更长，加重因素更复杂，VRT综合练习更多，DHI评分更高。
定制的VRT能充分减轻PPPD患者的症状并改善其生活质量。
