ABSTRACT
BACKGROUND:
This study focused on developing an upper limb rehabilitation program. In this regard, a steady state visual evoked potential (SSVEP) triggered brain computer interface (BCI)-functional electrical stimulation (FES) based action observation game featuring a flickering action video was designed.OBJECTIVE:
In particular, the synergetic effect of the game was investigated by combining the action observation paradigm with BCI based FES.METHODS:
The BCI-FES system was contrasted under two conditions with flickering action video and flickering noise video. In this regard, 11 right-handed subjects aged between 22-27 years were recruited. The differences in brain activation in response to the two conditions were examined.RESULTS:
The results indicate that T3 and P3 channels exhibited greater Mu suppression in 8-13 Hz for the action video than the noise video. Furthermore, T4, C4, and P4 channels indicated augmented high beta (21-30 Hz) for the action in contrast to the noise video. Finally, T4 indicated suppressed low beta (14-20 Hz) for the action video in contrast to the noise video.CONCLUSION:
The flickering action video based BCI-FES system induced a more synergetic effect on cortical activation than the flickering noise based system.Palavras-chave
