现今社会中由于种种因素，如自身机能下降、意外车祸、外伤等造成的肢体运动性障碍的病人在显著增加。临床上广泛使用下肢康复训练机器来辅助患者康复训练，而近年来脑机接口技术的飞速发展，使其在该康复领域得到极大的重视。脑机接口通过对肢体运动障碍患者运动想象或诱发产生的脑波信号进行识别，从而控制下肢康复设备实现辅助运动。

In today's society, due to various factors, the number of patients with limb dyskinesia caused by the functional decline, accidents, injuries and other causes is increased significantly. Clinically, lower limb rehabilitation training machines are widely used to assist patients in rehabilitation training. In recent years, the rapid development of brain-computer interface (BCI) technology has made great importance in this field of rehabilitation. The brain-computer interface recognizes the brain wave signals generated by motor imaging or induced motion of patients with limb movement disorders, thereby controlling the lower limb rehabilitation equipment to achieve auxiliary movement.
