Objective: to analyze the effects of brain activation by electroencephalography (EEG) in post-stroke patients during stimulation with Motor Imagery (MI), Functional Electrical Stimulation (FES) and Robotic Glove (RG). Methodology: EEG recordings of three (03) post-stroke subjects, with hand movement impairment during MI, FES, RG and combination of FES+RG, were analyzed and compared. Results: The analysis of the Mu rhythm demonstrated that therapies with RG, FES and FES+RG were able to significantly reduce the Relative Power (RP) of this rhythm in volunteer 1 (V1), when compared to IM therapy. In volunteer 2 (V2), we observed the same pattern, however, in volunteer 3 (V3) no statistical significance was observed in the application of FES and FES+RG, when compared to IM. Contrary to expectations, RG therapy in V3 demonstrated a pattern of elevation in the relative power of the Mu rhythm. However, when comparing RG with other therapies in this participant, significant and encouraging results were obtained. After analyzing the Beta Low rhythm, it was demonstrated that FES+RG therapy was superior and significant when compared to IM in the three individuals studied. FES-only therapy was also found to be significant in V2 and V3 compared to IM. During the Beta High frequency analysis, it was observed that FES+RG therapy was superior and significant when compared to IM in V1 and V3. V2 did not demonstrate statistically significant results. Conclusions: Relevant results were obtained using associated FES+RG stimulations. Therefore, it is concluded that the association of these therapies can assist in the post-stroke neuro-motor rehabilitation process, enabling the development of new neuro-rehabilitation protocols that are accessible and safe
