Untethered Home Therapy System

其目标是设计、建造和临床评估自由系留家庭治疗系统(UHTS)。本研究将重点放在卒中患者上肢功能运动的恢复上，目前对卒中后运动再学习的研究已经有了巨大的增长和研究。仔细指导、重复练习技能是提高恢复能力的关键。UHTS应该有助于改善上肢运动障碍的功能恢复的时间进程和数量。这个独特的系统将使用包含干表面肌电电极的臂章和一个小型无线电发射器来将肌电传输到附近的笔记本电脑。软件将在监测肌电的同时，通过一系列预先录制的电影指导患者。任务将包括各种手臂动作、抓握力跟踪、肌电跟踪和抓握力。通过监测肌电，该软件将区分任务，监测合规性，并提供实时用户反馈。在第一阶段中，我们将设计、构建和临床评估使用臂章遥测系统记录上肢肌电的可行性，开发任务识别算法，并开发用户界面软件原型。UHTS原型将在五名中风患者上进行临床评估，以确保任务辨别，有效的受试者 反馈和临床疗效。

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.
