Abstract: Lower limb exoskeleton rehabilitation robot is a kind of intelligent equipment providings rehabilitation exercise for the patients with lower limb dyskinesia or impaired mobility. Its development is of great theoretical significance and practical application value for the rehabilitation in China. Human factors engineering research can effectively improve the safety and efficiency of human-computer interaction of lower limb rehabilitation robot HRI. The research progress of human factors engineering of lower limb exoskeleton rehabilitation robot at home and abroad was deeply explored, and its research status and development trend were summarized. The related literatures was analyzed by literature retrieval method. It was found that HRI, gait behavior, structure design and safety issues are the research hotspots in the field of human factors engineering. Starting from human factors, this paper systematically reviewed the research progress and development trend of human factors engineering of lower limb exoskeleton rehabilitation robot at home and abroad, and presented the challenges, research focus and future development trend in the field of human factors engineering of lower limb exoskeleton rehabilitation robot in China. 

Key words: lower limb exoskeleton robot, rehabilitation robot, human factors engineering, the human-robot interaction, research and application progress
