目的 针对脑卒中患者上肢居家康复依从性低下及自我控制困境问题,构建融合积极体验设计理论的干预模型。方法 采用半结构访谈(n=13)结合情绪粒度卡片挖掘患者情感痛点,通过设计师工作坊(n=6)对困境进行解构与重构,构建“心理赋能、行为引导”双维度干预模型,运用改进型D-H参数法建立运动学方程,通过MATLAB仿真验证系统性能。结果 设计了“Posit-Move”居家康复系统,创新性集成六自由度机械臂提供物理支撑以抑制肌肉代偿,构建“软件、硬件、医师、社会支持”四端闭环体系。仿真结果表明,系统末端位置误差小于±2 mm,轨迹规划平滑,满足康复训练运动学要求。结论 该模型缓解了患者即时满足诉求与延迟康复收益之间的冲突,提出“情绪、行为、认知”多维干预策略及动静结合的交互模式,为解决康复情境下自我控制困境提供了新的设计路径。
Abstract
To address the issues of low compliance and Self-control Dilemma (SCD) in upper limb home rehabilitation for stroke patients, the work aims to construct an intervention model integrating positive experience design theory. Semi-structured interviews (n=13) combined with emotional granularity cards were used to explore patients' emotional pain points. Through designer workshops (n=6), dilemmas were deconstructed and reconstructed, establishing a two-dimensional intervention model of "psychological empowerment and behavioral guidance". The kinematic equations were established with the modified Denavit-Hartenberg (D-H) parameter method, and the system performance was verified through MATLAB simulation. The "Posit-Move" home rehabilitation system was developed, which integrated a six-degree-of-freedom (6-DOF) robotic arm to provide physical support, and construct a four-terminal closed-loop system of "software, hardware, physician and social support". Simulation results indicate that the system's end position error was less than ±2 mm with smooth trajectory planning, meeting the kinematic requirements for rehabilitation training. This model eases the conflict between patients' desire for instant gratification and long-term rehabilitation benefits. It proposes multi-dimensional intervention strategies covering "emotion, behavior and cognition", as well as an interactive mode combining static and dynamic states, offering a new design approach to address self-control dilemmas in rehabilitation scenarios.
