The rating of perceived exertion (RPE) is a widely used method for monitoring the load during training, as it provides insight into the subjective intensity of effort experienced during exercises. Considering the role of brain in monitoring and perception of the effort, several studies explored the effect of transcranial direct current stimulation (tDCS) on RPE in different populations. The aim of current study is to review the studies that investigated the effect of tDCS on RPE in three groups including healthy untrained people, physically active persons, and athletes. Nine databases were searched for papers assessing the effect of tDCS on RPE. The data from the included studies were extracted and methodological quality was examined using the risk of bias 2 (ROB2) tool. Thirty-three studies met the inclusion criteria. According to the meta-analysis, active a-tDCS significantly decreased the RPE compared to the sham stimulation. The a-tDCS could decrease the RPE when it was applied over M1 or DLPF. Regarding the measurement tool, Borg's scale 6-20 and OMNI scale could show an improvement in RPE scale. A-tDCS is a promising technique that can decrease the RPE. M1 and DLPFC are suggested as the target area of stimulation. From the tools that measure the RPE, Borg's RPE 6-20 and OMNI scale could better show the effect of a-tDCS.
自感用力度（RPE）评分是一种广泛用于监测训练负荷的方法，因为它能洞察运动过程中所体验到的主观用力强度。考虑到大脑在监测和感知用力方面的作用，多项研究探讨了经颅直流电刺激（tDCS）对不同人群RPE的影响。本研究的目的是回顾那些调查tDCS对包括健康未训练者、体育活动者和运动员在内的三组人群RPE影响的研究。检索了九个数据库以查找评估tDCS对RPE影响的论文。提取纳入研究的数据，并使用偏倚风险2（ROB2）工具检查方法学质量。33项研究符合纳入标准。根据荟萃分析，与假刺激相比，主动阳极tDCS显著降低了RPE。当阳极tDCS应用于M1或背外侧前额叶皮质（DLPF）时，可降低RPE。关于测量工具，Borg 6-20量表和OMNI量表可显示RPE量表有所改善。阳极tDCS是一种有前景的技术，可降低RPE。建议将M1和背外侧前额叶皮质（DLPFC）作为刺激目标区域。在测量RPE的工具中，Borg的RPE 6-20量表和OMNI量表能更好地显示阳极tDCS的效果。
