The Effectiveness of Rehabilitation Training Based on Brain-computer Interface Technology to Improve the Upper Limb Motor Function of Ischemic Stroke.

Brain computer interface(BCI) is a noninvasive nervous system intervention. As a new method, it is applied in rehabilitation by stimulating peripheral nerve, such as motor, vibration, sensory, in combination with other stimulations, such as transcranial magnetic stimulation, transcranial electrical stimulation, etc.

In traditional rehabilitation therapy, hand-holding training is completed by physical therapist. Rehabilitation robot is also used for auxiliary training. BCI therapy will stimulate patients to take part in rehabilitation training more actively and obtain better effects on the rehabilitation of stroke.
