已经开发了许多机器人设备来辅助手部康复;然而，其中大多数对于中风幸存者来说很难佩戴。本研究的目的是开发一种用于治疗屈曲挛缩的辅助装置，该装置支持每个手指的伸展，并且可以容易地佩戴在瘫痪的手上。为了方便使用，我们建议了一种新的佩戴方法，这种线驱动设备具有弹性骨架，允许用户将设备从手背延伸到指尖。通过指尖接触力和支撑力矩的估计来测量该装置的功能能力。结果表明，该器械提供了足够的扭矩，用于手指伸展，并控制了导丝张力。此外，实验结果证实，与其他设计相比，新设计显着减少了用户佩戴设备所需的时间。
Numerous robotic devices have been developed to assist hand rehabilitation; however, a majority of these are difficult for stroke survivors to wear. The purpose of this study was to develop an assistive device for treating flexion contracture, which supports the extension of each finger and may easily be worn on a paralyzed hand. To facilitate ease of use, we suggested a new wearing method for this wire-driven device with an elastic skeleton, allowing users to extend the device from the back of the hand onto the fingertip. The functional capacity of this device was measured through fingertip contact force and estimations of supporting torque. Results showed the device provides sufficient torque for finger extension with controlled wire tension. Moreover, experimental results confirmed that the novel design significantly decreased the time it took users to don the device compared to other designs.
