中风患者经常出现屈肌张力过强和手指伸肌无力，使患者难以张开患手进行功能性抓取。由于这种损伤，中风后的手康复对于恢复功能独立的生活方式是必不可少的。这项研究的目标是开发一种被动的、轻便的、可穿戴的设备，以帮助执行日常生活活动时的手功能。该设备名为Hand Spring操作的运动增强器(SMARTY)，使用一系列弹性绳帮助打开患者的手，这些弹性绳将伸展扭矩施加到手指关节，并补偿屈肌高张。描述了设备的设计和校准，以及对具有广泛手损伤的中风受试者进行的功能和可用性测试。在对8名患有手指屈肌高张症的中风患者进行的初步测试中，使用英俊的运动范围(p<；0.001)和功能能力(p=0.002)显著增加。在受试者的理想环境下，漂亮的设备会使握力有所下降，但这在统计学上并不显著(p=0.167)，似乎也不会对功能产生显著影响。总体而言，英俊显示了作为一种训练工具的前景，以促进重复的任务练习，以改善中风患者的手功能。英俊可以作为家庭治疗计划的一部分，也可以作为修复失去的功能的矫形器。
Stroke patients often have flexor hypertonia and finger extensor weakness, which makes it difficult to open their affected hand for functional grasp. Because of this impairment, hand rehabilitation after stroke is essential for restoring functional independent lifestyles. The goal of this study is to develop a passive, lightweight, wearable device to assist with hand function during performance of activities of daily living. The device, Hand Spring Operated Movement Enhancer (HandSOME), assists with opening the patient's hand using a series of elastic cords that apply extension torques to the finger joints and compensates for the flexor hypertonia. Device design and calibration are described as well as functional and usability testing with stroke subjects with a wide range of hand impairments. In initial testing with eight stroke subjects with finger flexor hypertonia, use of the HandSOME significantly increased range of motion (p < 0.001) and functional ability (p = 0.002). There was some decrease in grip strength with the HandSOME device at the subject's ideal setting, however this was not statistically significant (p = 0.167) and did not seem to have a significant effect on function. Overall HandSOME shows promise as a training tool to facilitate repetitive task practice for improving hand function in stroke patients. HandSOME can be used as part of a home-based therapy program, or as an orthotic for replacing lost function.
