Untethered Home Therapy System

目的是设计、构建和临床评估无系绳家庭治疗系统（UHTS）。研究将集中在中风患者的上肢功能运动恢复上，目前对中风后运动再学习的研究已经有了很大的发展和研究。仔细指导，重复练习的技能是必不可少的，以提高恢复。UHTS应该有助于改善上肢运动缺陷的时间过程和功能恢复的数量。这个独特的系统将使用包含干表面肌电信号电极的臂带和一个小型无线电发射器，将肌电信号传输到附近的笔记本电脑。在监测肌电图时，软件将通过一系列预先录制的电影来指导患者。任务将包括各种手臂运动、抓握力跟踪、肌电图跟踪和抓握力。通过监测肌电图，软件将区分任务，监测遵守情况，并提供实时用户反馈。在第一阶段，我们将设计、构建和临床评估用臂带遥测系统记录上肢肌电图的可行性，开发任务识别算法，并开发用户界面软件的原型。原型UHTS将在5个脑卒中受试者上进行临床评估，以确保任务区分，有效的受试者

The objective is to design, build, and clinically assess an Untethered Home Therapy System (UHTS). The research will focus on functional motor recovery in the upper extremity of stroke patients, There has currently been tremendous growth and research into motor relearning after stroke. Carefully directed, repetitive practice of skills is essential to improving recovery. The UHTS should aid in improving the time course and amount of functional recovery from upper extremity motor deficits. This unique system will employ armbands containing dry surface EMG electrodes and a small radio transmitter to transmit EMG to a nearby laptop computer. Software will instruct the patient through a series of prerecorded movies while monitoring EMG. Tasks will include a variety of arm movements, grasp force tracking, EMG tracking, and grasp strength. By monitoring EMG, the software will discriminate tasks, monitor compliance, and provide real-time user feedback. During Phase I we will design, build, and clinically evaluate the feasibility of recording upper extremity EMG with the armband telemetry system, develop algorithms for task discrimination, and a develop a prototype of the user interface software. The prototype UHTS will be clinically evaluated on five stroke subjects to ensure task discrimination, effective subject feedback, and clinical efficacy.
