Action monitoring is crucial to the successful execution of an action and understanding the actions of others. It is often impaired due to brain lesions, in particular after stroke. This systematic review aims to map the literature on the neurophysiological correlates of action monitoring in patients with brain lesions. Eighteen studies were identified and divided into two groups: studies on monitoring of one's own actions and studies on monitoring of the actions of others. The first group included EEG studies on monitoring of self-performed erroneous and correct actions. Impaired error detection (decreased error-related negativity) was observed in patients with lesions in the performance-monitoring network, as compared to healthy controls. Less consistent results were shown for error positivity and behavioral error monitoring performance. The second group of studies on monitoring of others' actions reported decreased mu frequency suppression, impaired readiness potential in the affected hemisphere and decreased EEG indices of error observation (observed error positivity and theta power) in stroke patients. As a whole, these results indicate distinct patterns of impaired neurophysiological activity related to monitoring one's own versus others' actions in patients with brain lesions. EEG recordings of this dissociation in the same patients might be a useful index of motor recovery, and therefore, potentially also beneficial in rehabilitation protocols.
动作监测对于成功执行一个动作以及理解他人的动作至关重要。它常常因脑部病变而受损，尤其是在中风后。本系统综述旨在梳理有关脑部病变患者动作监测的神经生理学相关性的文献。共识别出18项研究，并分为两组：关于自身动作监测的研究和关于他人动作监测的研究。第一组包括对自我执行的错误和正确动作进行监测的脑电图研究。与健康对照组相比，在执行监测网络有病变的患者中观察到错误检测受损（错误相关负波减少）。在错误正波及行为错误监测表现方面，结果不太一致。第二组关于他人动作监测的研究报告称，中风患者的μ频率抑制降低、患侧半球的准备电位受损以及错误观察的脑电图指标（观察到的错误正波及θ波功率）降低。总体而言，这些结果表明，脑部病变患者在监测自身动作与他人动作时，神经生理活动受损的模式有所不同。对同一患者这种分离情况的脑电图记录可能是运动恢复的一个有用指标，因此，在康复方案中可能也有益处。
