低成本机械装置辅助中风患者步行康复，实现双腿协同运动。
A Passive Mechanical Add-on for Treadmill Exercise (P-MATE) in Stroke Rehabilitation
- 通过弹性绳索与滑轮系统连接双侧腿，实现被动协同步态训练。
- 8名健康受试者测试显示装置易安装，能有效传递交互力并采集生物力学数据。
- 适合需要经济高效康复方案的临床场景，强调个性化适配的重要性。
机器人康复可提供高强度步态治疗并改善中风后运动功能，但许多设备因成本高、设置耗时长而难以临床推广。为此，我们设计、构建并评估了被动式跑步机附加装置（P-MATE），一种低成本、无源的末端执行器附加装置，通过往复式弹性绳索与滑轮系统耦合瘫痪侧与非瘫痪侧下肢运动。设计了两种人机接口，用于将弹性绳索连接至用户。在一位物理治疗师和八名健康参与者上测试了P-MATE及两个接口原型，收集了包括运动学和交互力在内的生物力学数据，并通过标准化问卷评估可用性与用户体验。两种接口均快速易安装，但用户感受存在差异，凸显个性化需求。还识别出未来改进方向，包括预张力调节、肌腱脱轨预防以及长期对步态影响的理解。初步结果表明，P-MATE具备提供有效、可及且可持续的中风步态康复的潜力。
原文摘要 · Abstract (English)
Robotic rehabilitation can deliver high-dose gait therapy and improve motor function after a stroke. However, for many devices, high costs and lengthy setup times limit clinical adoption. Thus, we designed, built, and evaluated the Passive Mechanical Add-on for Treadmill Exercise (P-MATE), a low-cost passive end-effector add-on for treadmills that couples the movement of the paretic and non-paretic legs via a reciprocating system of elastic cables and pulleys. Two human-device mechanical interfaces were designed to attach the elastic cables to the user. The P-MATE and two interface prototypes were tested with a physical therapist and eight unimpaired participants. Biomechanical data, including kinematics and interaction forces, were collected alongside standardized questionnaires to assess usability and user experience. Both interfaces were quick and easy to attach, though user experience differed, highlighting the need for personalization. We also identified areas for future improvement, including pretension adjustments, tendon derailing prevention, and understanding long-term impacts on user gait. Our preliminary findings underline the potential of the P-MATE to provide effective, accessible, and sustainable stroke gait rehabilitation.
