我们研究了旨在帮助中风后瘫痪手的机器人矫形器的性能。它是可穿戴的并且完全由用户控制，具有两种可能的作用：作为一种治疗工具，促进设备介导的手部锻炼以恢复神经肌肉功能；或作为在日常活动中使用的辅助设备，以帮助手部的功能使用。我们提出了一项试点研究的临床结果，该研究旨在对这些假设进行可行性测试。 11 名具有中等肌张力（上肢改良 Ashworth 量表 ≤ 2）的慢性中风（> 2 年）患者使用矫形器进行了为期一个月的训练方案。使用标准化结果测量对个体进行评估，无论是否有矫形器辅助。在没有机器人辅助的情况下，Fugl-Meyer 干预后评分显示出改善主要集中在上肢远端关节，这表明使用矫形器作为手部康复装置。机器人辅助干预后的行动研究手臂测试分数表明，该设备可以在抓取任务中发挥辅助作用。这些结果凸显了可穿戴和用户驱动的机器人手矫形器在延长中风后受影响上肢的使用和训练方面的潜力。
We studied the performance of a robotic orthosis designed to assist the paretic hand after stroke. It is wearable and fully user-controlled, serving two possible roles: as a therapeutic tool that facilitates device-mediated hand exercises to recover neuromuscular function or as an assistive device for use in everyday activities to aid functional use of the hand. We present the clinical outcomes of a pilot study designed as a feasibility test for these hypotheses. 11 chronic stroke (> 2 years) patients with moderate muscle tone (Modified Ashworth Scale ≤ 2 in upper extremity) engaged in a month-long training protocol using the orthosis. Individuals were evaluated using standardized outcome measures, both with and without orthosis assistance. Fugl-Meyer post intervention scores without robotic assistance showed improvement focused specifically at the distal joints of the upper limb, suggesting the use of the orthosis as a rehabilitative device for the hand. Action Research Arm Test scores post intervention with robotic assistance showed that the device may serve an assistive role in grasping tasks. These results highlight the potential for wearable and user-driven robotic hand orthoses to extend the use and training of the affected upper limb after stroke.
