Digital transformation (DT), the combination of information, computing, communication and connectivity technologies, which has triggered an effective upgrade of different aspects of market strategy, customer experience etc. Nowadays, rehabilitation assistive devices (RADs) are evolving to be more digital, intelligent and personalized. Digitalization and servitization have fostered to an emerging business model—the smart product–service system (Smart PSS). Therefore, DT of the RADs’ industry advocates not only the design of products and functions, the more important is the management of service processes and resource integration. With the increase in the elderly and disabled population, the requirement for RADs is becoming more urgent. However, research on Smart PSS for RAD is still limited. The rehabilitation assistive smart product–service systems (RASPSS) was introduced into the development of RADs based on the “Design and Management of DT” strategy through the service design of assistive devices and user requirements analysis. Further, an integrated design of RAD and Smart PSS has been created, a development method of RASPSS proposed, the theoretical model of the Smart PSS based on RADs built. To specify the service framework, this case study discusses the development of a home rehabilitation assistive system for femoral stem fracture patients. This paper evaluates the usability of the system, the results of which prove usability and effectiveness of the RASPSS development method. The RASPSS development model is designed to meet needs of stakeholders, improve the user rehabilitation experience, promote the service innovation of Smart PSS, bring certain market benefits of rehabilitation aids and create social value.

数字转换（DT）是信息，计算，通信和连接技术的结合，已经引发了市场策略，客户体验等各个方面的有效升级。如今，康复辅助设备（RAD）逐渐发展为数字化，智能和个性化。数字化和服务化已经发展成为一种新兴的商业模式-智能产品-服务系统（Smart PSS）。因此，RADs行业的DT不仅提倡产品和功能的设计，更重要的是服务流程和资源集成的管理。随着老年人和残疾人口的增加，对RAD的需求变得越来越紧迫。但是，针对RAD的Smart PSS的研究仍然很有限。通过辅助设备的服务设计和用户需求分析，基于“ DT的设计和管理”策略将康复辅助智能产品服务系统（RASPSS）引入了RAD的开发中。进一步，建立了RAD与智能PSS的集成设计，提出了RASSPS的开发方法，建立了基于RAD的智能PSS的理论模型。为了指定服务框架，本案例研究讨论了针对股骨干骨折患者的家庭康复辅助系统的开发。本文评估了系统的可用性，其结果证明了RASPSS开发方法的可用性和有效性。RASPSS开发模型旨在满足利益相关者的需求，改善用户的康复体验，
