Stroke patients often have inappropriate finger flexor activation and finger extensor weakness, which makes it difficult to open their affected hand for functional grasp. The goal was to develop a passive, lightweight, wearable device to enable improved hand function during performance of activities of daily living. The device, HandSOME II, assists with opening the patient's hand using 11 elastic actuators that apply extension torques to finger and thumb joints. Device design and initial testing are described. A novel mechanical design applies forces orthogonal to the finger segments despite the fact that all of the device DOFs are not aligned with human joint DOF. In initial testing with seven stroke subjects with impaired hand function, use of HandSOME II significantly increased maximum extension angles and range of motion in all of the index finger joints (P<;0.05). HandSOME II allows performance of all the grip patterns used in daily activities and can be used as part of home-based therapy programs.
中风患者常常存在手指屈肌激活不当以及手指伸肌无力的问题，这使得他们难以张开患手进行功能性抓握。目标是研发一种被动、轻便的可穿戴设备，以在日常生活活动中改善手部功能。该设备名为HandSOME II，通过11个弹性致动器协助患者张开手，这些致动器向手指和拇指关节施加伸展扭矩。文中描述了该设备的设计及初步测试情况。尽管该设备的所有自由度并非与人体关节自由度对齐，但一种新颖的机械设计能将力施加于与手指节段正交的方向。在对7名手部功能受损的中风受试者进行的初步测试中，使用HandSOME II显著增加了所有食指关节的最大伸展角度和活动范围（P<0.05）。HandSOME II能够实现日常活动中使用的所有抓握模式，并且可作为家庭治疗方案的一部分使用。
