脑机接口技术在慢性脑卒中患者上肢康复中的研究进展

脑机接口(BCI)技术可以激活神经系统可塑性。记录大脑活动的技术包括侵入性和非侵入性方法，后者具有安全、便携和低成本的优点，但容易产生信号污染。在慢性脑卒中患者上肢康复中，目前通常采用脑电图结合机械臂的方法。临床上，BCI多与其他康复方法联合应用，可提高康复效果。未来需要提高BCI运动意图解码的准确性，对患者进行分层和量身定制治疗，开发混合式和便携式BCI系统。

Advance in Application of Brain-computer Interface for Upper Limb Rehabilitation for Patients with Chronic Stroke (review)

Brain-computer interface (BCI) technology can activate the plasticity of the nervous system and induce the reconnection of nervous system information pathways. Techniques for recording brain activity include invasive methods and non-invasive methods. Non-invasive methods are safer, more portable and cheaper, but are prone to signal pollution. For upper limbs rehabilitation in patients with severe chronic stroke, BCI of electroencephalogram and robotic arm is usually used, almost combined with other rehabilitation approaches, and seems to improve the effectiveness. It is necessary to improve the accuracy of BCI motion intention decoding, carry out hierarchical and customized treatment for patients, develop hybrid and portable BCI system.
