在之前的工作中，我们开发了一种外骨骼，手部弹簧操作运动增强器（HandSOME II），允许15个手部自由度（DOF）的运动。可添加11个独立的弹性元件，为手部功能受损的个人定制扩展辅助。在这项对12名中风患者进行的初步研究中，我们测量了佩戴该设备后活动范围（ROM）和上肢功能的立即改善。在PIP关节（p= 0.01）和DIP关节（p= 0.026）处，食指关节活动度显著改善；在MCP关节（p< 0.001）、PIP关节（p= 0.013）和DIP关节（p= 0.016）处，食指最大伸度显著增加。拇指CMC外展max （p= 0.017）和CMC屈伸ROM也增加（p= 0.04）。在涉及各种物体的抓握和释放任务中，有6名受试者在没有帮助的情况下无法完成任务。在这6名受试者中，42项任务中有13项是在没有帮助的情况下完成的，而42项任务中有36项是在佩戴“英俊II”的情况下完成的。尽管该装置提供了延伸辅助，但屈曲握力并没有统计学上的下降。HandSOME II可以潜在地提高中重度手部损伤患者重复性任务练习的有效性，允许他们完成不可能独立完成的抓取和释放任务。
In previous work, we developed an exoskeleton, Hand Spring Operated Movement Enhancer (HandSOME II), that allows movement at 15 hand degrees of freedom (DOF). Eleven separate elastic elements can be added to customize the extension assistance for individuals with impaired hand function. In this pilot study of twelve individuals with stroke, we measured the immediate improvements in range of motion (ROM) and upper extremity function when wearing the device. Index finger ROM was significantly improved at the PIP (p=.01) and DIP joints (p=.026), and the max extension was significantly increased at the MCP (p<.001), PIP (p=.013) and DIP joints (p=.016). The thumb CMC abduction max (p=.017) and CMC flexion/extension ROM also increased (p=.04). In a grip and release task involving various objects, six subjects were unable to complete the tasks without assistance. Across these 6 subjects, 13 of 42 tasks were completed without assistance, while 36 of 42 tasks were completed when wearing HandSOME II. Despite the extension assistance provided by the device, flexion grip force was not statistically decreased. HandSOME II can potentially increase the effectiveness of repetitive task practice in patients with moderate-severe hand impairment by allowing completion of grasp and release tasks that are impossible to complete unassisted.
