Background: Patients with post-stroke hemiparesis have poor postural stability; nevertheless, it is unclear whether vestibular rehabilitation affects gait performance after a stroke or not. We performed a systematic review of randomized controlled trials to investigate the effects of vestibular rehabilitation on gait performance in patients with post stroke. Methods: The Medline, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and Cumulative Index to Nursing and Allied Health Literature databases were comprehensively searched. All literature published from each source's earliest date to June 2019 was included. Study selection and data extraction were performed independently by paired reviewers. Outcomes of gait performance were the 10-Meter Walking Test, Timed Up and Go Test, and Dynamic Gait Index. We applied the Physiotherapy Evidence Database scale to evaluate the risk of bias and the Grading of Recommendations Assessment, Development and Evaluation system to evaluate the quality of a body of evidence. Results: Three studies were included, and two out of three trials showed beneficial effects of vestibular rehabilitation in post-stroke patients. Quality assessment using the Grading of Recommendations Assessment, Development and Evaluation criteria found very low-quality evidence of all included studies due to inadequate allocation concealment, low participant numbers, and lack of blinding. Conclusion: This review found beneficial effects of vestibular rehabilitation on gait performance in patients with stroke. However, due to the very low-quality evidence of previous randomized controlled trials as assessed by the Grading of Recommendations Assessment, Development and Evaluation criteria, definitive conclusions on the effectiveness of vestibular rehabilitation cannot be made. Hence, more high-quality and large-scale randomized controlled trials of vestibular rehabilitation after stroke are needed.

背景：中风后偏瘫患者的姿势稳定性较差；然而，尚不清楚前庭康复是否会影响中风后的步态表现。我们对随机对照试验进行了系统评价，以调查前庭康复对中风后患者步态表现的影响。方法：全面搜索Medline，对照试验的Cochrane中央登记册，理疗证据数据库以及护理和专职健康文献的累积索引。包括从每个来源最早到2019年6月发布的所有文献。研究选择和数据提取由配对的审阅者独立进行。步态表现的结果是10米步行测试，定时走步测试和动态步态指数。我们使用了物理疗法证据数据库量表来评估偏见的风险，并使用推荐评估，发展和评估系统的等级来评估证据的质量。结果：包括三项研究，三分之二的研究表明中风后患者前庭康复的有益作用。使用“推荐评估，发展和评估等级”标准进行的质量评估发现，由于分配隐瞒不足，参与者人数少和没有盲目性，所有纳入研究的证据质量都很低。结论：这项审查发现中风患者前庭康复对步态表现的有益影响。然而，由于建议评估，发展和评估标准分级所评估的先前随机对照试验的证据质量很低，因此无法就前庭康复的有效性做出明确的结论。因此，需要更多高质量和大规模的中风后前庭康复的随机对照试验。
