Abstract

Objective: To evaluate the concurrent and training effects of action observation (AO) and action execution with mirror visual feedback (MVF) on the activation of the mirror neuron system (MNS) and its relationship with the activation of the motor cortex in stroke individuals.

Methods: A literature search using CINAHL, PubMed, PsycINFO, Medline, Web of Science, and SCOPUS to find relevant studies was performed.

Results: A total of 19 articles were included. Two functional magnetic resonance imaging (fMRI) studies reported that MVF could activate the ipsilesional primary motor cortex as well as the MNS in stroke individuals, whereas two other fMRI studies found that the MNS was not activated by MVF in stroke individuals. Two clinical trials reported that long-term action execution with MVF induced a shift of activation toward the ipsilesional hemisphere. Five fMRI studies showed that AO activated the MNS, of which, three found the activation of movement-related areas. Five electroencephalography (EEG) studies demonstrated that AO or MVF enhanced mu suppression over the sensorimotor cortex.

Conclusions: MVF may contribute to stroke recovery by revising the interhemispheric imbalance caused by stroke due to the activation of the MNS. AO may also promote motor relearning in stroke individuals by activating the MNS and motor cortex.

卒中中镜像视觉反馈的动作观察和动作执行过程中镜像神经元系统的激活:一项系统综述。

目的:探讨动作观察(AO)和镜像视觉反馈动作执行(MVF)对脑卒中患者镜像神经元系统(MNS)激活的同步和训练效应及其与运动皮层激活的关系。方法:通过CINAHL、PubMed、PsycINFO、Medline、Web of Science、SCOPUS等数据库进行文献检索，查找相关研究。结果:共纳入19篇文献。两项功能磁共振成像(fMRI)研究报道，MVF可以激活脑卒中患者同侧初级运动皮层和MNS，而另外两项功能磁共振成像研究发现，MVF不能激活脑卒中患者的MNS。两项临床试验报告了MVF的长期动作执行诱导了向同侧半球激活的转移。5项fMRI研究表明，AO激活了MNS，其中3项发现了运动相关区域的激活。五项脑电图(EEG)研究表明，AO或MVF增强了对感觉运动皮层的mu抑制。结论:MVF可能通过改善MNS激活引起的脑卒中半球间失衡而促进脑卒中恢复。AO也可能通过激活MNS和运动皮层来促进中风患者的运动再学习。
