Table 8 Results of real-time testing for 5 patients with tetraplegia with the repeated command of intentional signals

From: Hybrid brain–computer interface for biomedical cyber-physical system application using wireless embedded EEG systems

Five patients with tetraplegia (SCI1 -SCI5)

Testing wheelchair commands eyes closed for on/off command and user chosen 3-task for left, forward, right commands (each runs at 25 times)
