The work aims to design and study the man-machine elements of patients to improve the rehabilitation experience of stroke patients and help patients recover their upper limbs. Firstly, physiological and psychological characteristics of stroke patients were analyzed. The dominant and invisible disorders were analyzed. The use status of upper limb rehabilitation products was investigated. And the existing problems of existing products were analyzed and summarized to provide the design basis for upper limb rehabilitation products. Secondly, based on ergonomic analysis of the upper limb movement characteristics and information perception characteristics of patients, key points of upper limb rehabilitation product design were discussed. Finally, based on user analysis and man-machine analysis, the design was developed from product size, information interaction, color and material to provide solutions for patients' upper limb rehabilitation, and the design scheme was verified through comparative analysis. Through the systematic study of the man-machine characteristics of patients and rehabilitation products, the ergonomic upper limb rehabilitation products were designed. It is feasible to analyze the problems existing in stroke rehabilitation products from the perspective of ergonomics, and the problems existing in man-machine aspects of stroke rehabilitation products can be effectively solved through other sensory channels, providing reference for the design of other rehabilitation products.
