Brain-computer interface based stroke rehabilitation for hemiplegia

摘要

Stroke is widely common cause of death and disability in adult. It is occurred when the blood supply in the brain is ruptured or blocked. Post stroke rehabilitation is the most important for stroke survivors because it assists them to restore their physical function such as arm movement, walking and daily life activity. Neuro-rehabilitation can enhance neuron pathways and improve motor function of patients. The neuron system can be restored their function and it is called neuroplasticity. The purpose of this paper is to develop stroke rehabilitation for hemiplegia based on Brain-computer interface (BCI). ERD/ERS which occur during motor imagery and motor execution of arm or leg are used as the control in this system. Most of BCI based stroke rehabilitation classified between right and left arm but stroke patients with hemiplegia cannot move their arm and leg on each side of the body. So this system is designed to classify between arm and leg. The upper limb and lower limb rehabilitation device are controlled from their motor imagery and feed back to user via rehabilitation device and virtual reality game. The rehabilitation system was design with facilitation and suitability for stroke patients.
