ARM ORTHOSIS FOR MOVEMENT TRAINING AFTER STROKE

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。该项目的总体目标是开发一套上肢训练系统，供中风患者在诊所或家中练习手臂和手的运动。本研究的目标是对手臂矫形器进行初步测试，作为训练系统的一部分，该矫形器将辅助和测量手臂的运动。本研究将在受保护的UCI环境中测试矫形器。该矫形器是威尔明顿机器人外骨骼(WREX)的改良版，WREX是一种被动反重力外骨骼，使用橡皮筋让手臂感觉失重。WREX最初由Tariq Rahman博士(Rahman等人)设计。1995年)，作为肌肉营养不良儿童的辅助设备。例如，虚弱到不能移动手臂以对抗重力的儿童可以自行进食和投球，方法是将手臂放在矫形器中。WREX已经被我们的实验室规模化，作为一种运动训练设备，供中风成人使用。在这项研究中，我们将量化使用矫形器减轻手臂重量对中风后手臂移动能力的影响。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The overall goal of this project is to develop an upper extremity training system for use by people with stroke to practice arm and hand movement in the clinic or at home. The goal of the present study is to perform preliminary tests on an arm orthosis that will assist and measure arm motion as part of the training system. The present study will test the orthosis in a protected UCI environment. The orthosis is a modified version of the Wilmington Robotic Exoskeleton (WREX), which is a passive antigravity exoskeleton that uses rubber bands to make the arm feel weightless. WREX was originally designed by Dr. Tariq Rahman (Rahman et al. 1995) for use as an assistive device for children with muscular dystrophy. Children who are too weak to move their arm against gravity can self-feed and throw a ball, for example, by placing their arm in the orthosis. WREX has been scaled by our laboratory for use as a movement training device to be used by adults with stroke. In the present study, we will quantify how relieving the weight of the arm with the orthosis affects the ability to move the arm after stroke.
