The challenge of controlling an auditory BCI in the case of severe motor disability

Abstract: Background: The locked-in syndrome (LIS), due to a lesion in the pons, impedes communication. This situation can also be met after some severe brain injury or in advanced Amyotrophic Lateral Sclerosis (ALS). In the most severe condition, the persons cannot communicate at all because of a complete oculomotor paralysis (Complete LIS or CLIS). This even prevents the detection of consciousness. Some studies suggest that auditory brain-computer interface (BCI) could restore a communication through a yes-no code. Me… Show more

“…Seventeen out of 18 healthy subjects obtained online BCI accuracy above chance level. Results were more mitigated amongst patients as two patients with advanced ALS were at chance level, while the other two could control the BCI with perfect accuracy 68 . In contrast, the three patients with locked-in syndrome due to a brainstem injury could not control the BCI.…”

“…Then a two-class Naive Bayes classifier was trained, based on the spatially filtered training data. More information on this classifier can be found in Seguin et al 68 . At the end of calibration, a leave-one-out based cross-validation was used to evaluate the quality of this calibration.…”

“…Nevertheless, game-oriented solutions seem to be a promising way to enhance user motivation [27]. Despite high performance rates in some studies, the majority of BCI systems and applications are mainly used in a research environment and have yet to be successfully utilized in patients' homes for continuous and everyday use [28].…”
