摘要: EEG-based discrimination between different motor imagery states has been subject of a number studies in healthy subjects. We investigated the EEG 15 patients with complete spinal cord injury during imagined right hand, left and feet movements. In detail we studied pair-wise functions 3 types imagery. The following classification accuracies (mean ± SD) were obtained: versus hand 65.03% 8.52, 68.19% 11.08, 65.05% 9.25. 5 out 8 paralegic patients, accuracy was greater than 70% but only 1 7 tetraplagic patients. present findings provide evidence that majority paraplegic an BCI could achieve satisfied results. tetraplegic however, it is expected extensive training-sessions are necessary to good performance at least some
