g.tec performed initial tests with robotic feedback. A motor imagery based Brain-Computer Interface (BCI) is presented that is linked to a rehebilitation robot.

The BCI system is used to measure the activation of the sensorimotor cortex to control external supporting robotic devices such as exoskeletons or orthotic devices. The robotic device has the purpose to move the limbs of the patient and this activates again the sensorimotor cortex. The activation can be seen as ERD/ERS changes…
