Research On The Design Of Lower Limb Rehabilitation Aids Based On User Experience

As China’s population ages,the health problems of the elderly are becoming increasingly prominent and medical resources are under great pressure,the use of home rehabilitation to address the lower limb impairment of the elderly has become a future trend.Currently,there is little research on home lower limb rehabilitation aids,especially on home lower limb rehabilitation robots,and commercial rehabilitation robots are mostly expensive and large in size,so it is important to design a lower limb rehabilitation aid for elderly people with lower limb impairment in the home environment.Firstly,by analysing the ageing population in China and its related problems,this thesis identifies an opportunity point for the design of lower limb rehabilitation aids,and through a detailed analysis of the development status and classification of lower limb rehabilitation aids,a home lower limb rehabilitation robot is finally chosen as the design practice ground.Secondly,the theory of user experience and the characteristics of the elderly with lower limb impairment are analysed in all aspects,and the characteristics of the elderly in terms of physiology,psychology and physical scale are summarised to provide theoretical support for the following user research and product design.The design methodology of the user experience-based home lower limb rehabilitation aids is summarised and refined to guide the design development of the product.Finally,in the design practice section,the nine elements of user experience and the four principles of user experience design are applied to the design of the lower limb rehabilitation robot based on the above research,starting from function,appearance,structure,colour,material and size,and designing the interaction interface according to the user’s needs.The research and analysis in this paper can provide theoretical support and practical guidance for the design and improvement of lower limb rehabilitation aids,meet the rehabilitation needs of the elderly with lower limb impairment in the home environment,and improve the quality of life of the elderly.At the same time,it can also make some contribution to the development of the rehabilitation of the elderly.
