Mirror visual feedback (MVF), a noninvasive treatment method, is attracting attention as a possibility to promote the recovery of upper limb function in stroke patients. However, the cognitive effects of this therapy have received limited attention in the existing literature. To address this gap, we conducted a systematic review and meta-analysis to investigate the relationship between upper limb function and cognition in stroke patients and to evaluate the effect of MVF on improving upper limb function. A comprehensive search was performed on the Embase, MEDLINE, and PubMed databases to identify original articles and clinical studies published between 2013 and 2022. Qualitative analysis was performed using the Cochrane Risk of Bias tool, and in the quantitative analysis, a random-effects model was used as the effect model, and standard mean difference (SMD) was used as the effect measure. Eight studies that met the inclusion criteria were entered in the analysis. Data extraction included an assessment tool for upper extremity function. Results of the quantitative analysis demonstrate that MVF was effective in improving upper extremity function in stroke patients (SMD = 0.94, 95% CI 0.69 to 1.20). In conclusion, this systematic review and meta-analysis provides evidence supporting the effectiveness of MVF in improving upper limb function in stroke patients. However, further studies are needed to investigate the cognitive effects of MVF and elucidate the underlying mechanisms.
镜像视觉反馈（MVF）是一种非侵入性治疗方法，作为促进中风患者上肢功能恢复的一种可能性正受到关注。然而，这种疗法的认知效应在现有文献中受到的关注有限。为了填补这一空白，我们进行了一项系统综述和荟萃分析，以研究中风患者上肢功能与认知之间的关系，并评估MVF对改善上肢功能的效果。我们在Embase、MEDLINE和PubMed数据库上进行了全面检索，以识别2013年至2022年期间发表的原创文章和临床研究。使用Cochrane偏倚风险工具进行定性分析，在定量分析中，使用随机效应模型作为效应模型，并使用标准化均值差（SMD）作为效应量度。八项符合纳入标准的研究进入分析。数据提取包括上肢功能评估工具。定量分析结果表明，MVF对改善中风患者的上肢功能有效（SMD = 0.94，95% CI 0.69至1.20）。总之，这项系统综述和荟萃分析提供了证据，支持MVF对改善中风患者上肢功能的有效性。然而，需要进一步的研究来调查MVF的认知效应并阐明其潜在机制。
