Hand rehabilitation after stroke is essential for restoring functional independent lifestyles. After stroke, patients often have flexor hypertonia, making it difficult to open their hand for functional grasp. The development and initial testing of a passive hand rehabilitation device is discussed. The device, Hand Spring Operated Movement Enhancer (HandSOME), assists with opening the patient's hand using a series of bungee cords that apply extension torques to the finger joints that compensate for the flexor hypertonia. This results in significant increase in range of motion and functional use when wearing HandSOME, even in severely impaired subjects. Device design, calibration, and range of motion are described as well as functional and usability testing with stroke subjects.
中风后的手部康复对于恢复功能独立的生活方式至关重要。中风后，患者常出现屈肌肌张力亢进，导致难以张开手进行功能性抓握。本文讨论了一种被动手部康复装置的开发和初步测试。该装置名为手部弹簧驱动运动增强器（HandSOME），通过一系列弹力绳协助患者张开手，这些弹力绳向手指关节施加伸展扭矩，以补偿屈肌肌张力亢进。即使对于严重受损的受试者，佩戴HandSOME时也能显著增加关节活动范围和功能使用。文中描述了该装置的设计、校准和活动范围，以及对中风受试者的功能和可用性测试。
