我们提出一种在为中风后上肢偏瘫患者设计的手部矫形器背景下稳定拇指的双缆线方法。这种缆线网络为拇指增加了对掌/复位能力，并增加了形成能够成功操作物体的手部姿势的可能性。除了被动拇指版本（两根缆线长度均固定），我们的方法还允许单驱动器主动拇指版本（伸展缆线被驱动，而外展肌保持被动），这允许一定范围的运动，旨在促进抓握的形成和维持。我们对五名慢性中风幸存者进行了实验，包括单手抗阻牵拉任务和使用模拟现实世界物体的双手扭转任务；这些实验探究了拇指辅助对抓握稳定性和功能性运动范围的影响。我们的结果表明，主动拇指版本和被动拇指版本在相对于无装置基线提高抓握力产生方面都取得了相似的性能，但主动拇指稳定使使用者能够更长时间地维持抓握。
We propose a dual-cable method of stabilizing the thumb in the context of a hand orthosis designed for individuals with upper extremity hemiparesis after stroke. This cable network adds opposition/reposition capabilities to the thumb, and increases the likelihood of forming a hand pose that can successfully manipulate objects. In addition to a passive-thumb version (where both cables are of fixed length), our approach also allows for a single-actuator active-thumb version (where the extension cable is actuated while the abductor remains passive), which allows a range of motion intended to facilitate creating and maintaining grasps. We performed experiments with five chronic stroke survivors consisting of unimanual resistive-pull tasks and bimanual twisting tasks with simulated real-world objects; these explored the effects of thumb assistance on grasp stability and functional range of motion. Our results show that both active- and passive-thumb versions achieved similar performance in terms of improving grasp force generation over a no-device baseline, but active thumb stabilization enabled users to maintain grasps for longer durations.
