Introduction : The purpose of this study was to review the mechanisms, clinical effects, and considerations for the use of non-invasive brain stimulation methods for stroke patients. This study reviewed recently published papers focusing on tDCS, rTMS, and PBM, which are mainly used in clinical practice among non-invasive brain stimulation methods. Discussion : tDCS, rTMS, and PBM control brain activity (inhibit or increase cortical excitability) by stimulating the brain using micro-currents (1~2mA), magnetic field change, and near infrared radiation. As a result, it has a positive effect on the improvement of brain function in stroke patients, and was found to be effective in improving motor and cognitive functions. Nevertheless, the exact mechanism of this non-invasive brain stimulation method is still unclear, and clear guidelines such as the intervention period, intensity, and application area in relation to clinical application have not yet been fully developed. Conclusion : In the future, it is expected that clearer evidence and specific clinical guidelines will be studied through various animal experiments and additional clinical studies for a clear mechanism for stroke rehabilitation and efficient clinical application.
