The design and preliminary assessment of a semi-powered hand and arm exoskeleton is described. The exoskeleton is designed to enable bimanual activities of daily living for individuals with chronic, upper-limb hemiparesis resulting from stroke. Specifically, the device augments the user’s grasp strength and ability to extend the affected hand for bimanual tasks and supplements wrist and elbow stability while conducting these tasks. The exoskeleton is battery-powered and self-contained with all electronics and power units placed within the device structure. A preliminary assessment of the exoskeleton was performed with three subjects having right-sided upper-limb motor deficit resulting from stroke. For subjects with limited hand and arm functionality, the exoskeleton increased grasp strength and improved the ability to perform representative bimanual tasks.

初步评估手和手臂的外骨骼，以使偏瘫患者实现双向任务

描述了半动力手和手臂外骨骼的设计和初步评估。外骨骼的设计旨在使患有中风的慢性上肢偏瘫患者能够进行日常生活的双向活动。具体地，该设备增强了用户的抓握力，并具有将受影响的手伸出来进行双向任务的能力，并在执行这些任务时增强了手腕和肘部的稳定性。外骨骼由电池供电，并且设备齐全，所有电子设备和电源单元都放置在设备结构内。对三名患有中风的右上肢运动功能障碍的受试者进行了外骨骼的初步评估。对于手和手臂功能受限的对象，
