Summary: Cerebral Vascular Accident (CVA) affects thousands of people around the world,
consequently bringing motor and visual data, oratory difficulties and other damages. It is known that the voluntary movement of the limbs reflects on a cerebral activation mainly on the motor cerebral cortex that can be captured by electroencephalogram (EEG) electrodes, however, in a similar way, an increase in cortical activity is also perceived during Motor Imagination activities ( IM) situation WHERE the individual just thinks about the movement without actually listening to it. This research used two patients from the Centro de Reabilitação Física do Espírito Santo (CREFES) who suffered a stroke to participate in the IM and active pedaling tests, the data were filtered through the Fast Fourier Transform (FFT) and Common Average Reference (CAR) ), after the data were analyzed by the Matlab software to determine the Relative Power (PR), to determine the significant results of the PR values, the log(PR/1-PR) criterion was used. The results of the PR assessment were compared during the active pedaling task and IM for each research participant, the alpha bands (8 to 12 Hz), low beta (13 to 22 Hz) and high beta bands (23 to 30 Hz) were analyzed). The similarity relationship between active pedaling and IM reached 85.6% for one of the analyses.
