Action observation training (AOT) has been used as a new intervention for improving upper limb motor functions in people with stroke. This systematic review and meta-analysis aims to investigate the effects of AOT on improving upper limb motor functions in people with stroke.
We searched ten electronic databases to identify randomized controlled trials (RCTs) about the effects of AOT on upper limb motor functions in stroke survivors. Methodological quality of included studies was assessed by the Risk of Bias Tool in the Cochrane Handbook for Systematic Reviews of Interventions. A random-effects meta-analysis was performed by pooling the standardized mean difference (SMD) of upper limb motor outcomes.
Seven studies of 276 participants with stroke were included. Meta-analysis showed a significant effect favoring AOT on improving upper limb motor functions in patients with stroke [SMD = 0.35, 95% confidence interval [CI], 0.10 to 0.61, I2 = 10.14%, p = 0.007].
AOT appears to be an effective intervention for improving the upper limb motor functions in people after stroke. Further studies need to investigate the neural mechanism underlying the effects of AOT.
动作观察训练（AOT）已被用作改善脑卒中患者上肢运动功能的新干预措施。本系统评价和荟萃分析旨在调查 AOT 对改善脑卒中患者上肢运动功能的影响。
我们检索了十个电子数据库，以确定关于动作观察训练对脑卒中幸存者上肢运动功能影响的随机对照试验（RCT）。使用 Cochrane 干预措施系统评价手册中的偏倚风险工具评估纳入研究的方法学质量。通过汇总上肢运动结局的标准化均数差值（SMD）进行随机效应荟萃分析。
纳入了 7 项共 276 名脑卒中患者的研究。荟萃分析显示，动作观察训练对改善脑卒中患者上肢运动功能具有显著效果[SMD=0.35，95%置信区间（CI）：0.10 至 0.61，I2=10.14%，p=0.007]。
动作观察训练似乎是一种改善脑卒中后患者上肢运动功能的有效干预措施。需要进一步的研究来探讨动作观察训练效果的神经机制。
