Because of that, the use of Virtual Reality (VR) can be an important intervention for the recovery of these individuals. We analyzed the coherence of the cortical activation of stroke patients submitted to a virtual reality game. Methods: Twelve patients participated in the study, 6 with left brain injury (PE), with an average age of 54.1 years (± 9.4) and 6 with right injury (PD), with an average age of ± 50.6 years (± 5.8) and 12 healthy individuals who activated the left brain hemisphere (SE) and the right (SD). All participants made 15 attempts at the Kinect Sports darts game on the Xbox 360 Kinect. EEG signals were recorded by Emotiv EPOC and motor performance by the game score. The raw EEG signal was processed in Matlab, through the coherence analysis of the frontal (FC5, FC6) and parietal (P7, P8) channels, in alpha and beta rhythms and the absolute error for motor performance was calculated. Statistical analysis was performed using ANOVA, with Tukey's post hoc test. Results: Analyzing the alpha rhythm, there was no significant difference between patients and healthy individuals in the coherence of the primary motor areas (FC5-FC6), left primary motor and parietal area (FC5-P7) and left primary motor and right parietal area (FC5-P8). The PD group showed lower values than the SD group (p = 0.002) for coherence in the right primary motor area and left parietal area (FC6-P7). In FC6-P8, the PE group had greater coherence than the SE group (p = 0.035) and in P7-P8, the coherence value of the PE group was greater than SE (p = 0.0001) and the PD group was lower than SD (p = 0.0001). In the beta rhythm, the PD group showed less coherence than the SD (p = 0.0001) in P7-P8. As for motor performance, the PD group had a greater absolute error than the SD group (p = 0.0001). Conclusion: The distinctive neural coherence between patients with left and right brain injury reflected the potential for reorganization of the cortical areas, suggesting that the laterality of the injury should be taken into account when planning the execution of virtual reality games for stroke patients.Acesso AbertoAcidente vascular cerebralEletroencefalografiaRealidade virtualdoctoralThesisCNPQ::CIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONAL
