ИСТИНА

Attempted movements have recently become common in invasive studies as a way to send commands via BCIs and have been successfully employed in some studies of neurorehabilitation using noninvasive BCIs. Nevertheless, they are still far less common in noninvasive BCIs than motor imagery. We proposed a hypothesis that attempted movements can be more compatible with the interaction with the external world than imaginary movements and therefore may help to use BCIs more effectively. The hypothesis was tested in 15 healthy participants who were asked to make prosaccades, which represented an external task, and quasi-movements (movement attempts minimized down to complete extinction of related muscle activation), which were used as a model of attempted movements. Preliminary results of the study were mostly in line with the predictions, although more studies are required for more definite conclusions. The study also may be considered as a new demonstration of the potential of quasi-movements, a very little explored phenomenon, for BCI research.
