A Personal Status Monitor for the Home

这一第二阶段SBIR的目的是开发一种便携式、完全无线的系统，该系统可以检测、处理和分析肌肉活动，以远程监控个人的功能状态。个人状态监测器(PSM)将以连续和畅通无阻的方式远程监控执行运动任务时肌肉的使用情况。通过对表面肌电(EMG)信号的模式识别，PSM将为护理人员提供患者身体活动程度的客观参数测量，如围墙、坐着、个人护理和进食。PSM将由三个部分组成：1)四个无线肌电传感器，2)身体穿戴收发机(中继器)，以及3)基站，处理信号以进行模式识别和特征提取。信息可以通过电话线或互联网发送到远程位置。该计划第二阶段的具体目标是：目标1：继续第一阶段开发中风患者的模式识别算法；目标2：设计和构建PSM的硬件和软件工作原型；以及目标3：在家庭环境中在中风患者中现场测试原型无线系统。拟议的商业应用：MA将主要通过使该线路成为一个有效的康复场所来增强临床服务。此外，PSM将直接适用于工地评估的人体工效学领域，或作为促进熟练动作培训的反馈手段应用于体育或娱乐活动。康复领域的许多其他应用可能包括监测震颤或其他神经肌肉疾病的药物治疗，或家庭锻炼依从性。该项目开发的知识库和原型可直接移植到其他从皮肤记录的生物信号采集系统，如脑电和心电。

The purpose of this Phase II SBIR is to develop a portable and completely wireless system that detects, processes, and analyzes muscle activity for remotely monitoring the functional status of an individual. The Personal Status Monitor (PSM) will remotely monitor the use of muscles during the exertion of motor tasks in a continuous and unobstructed fashion. Through pattern recognition of surface electromyographic (EMG) signals, the PSM will provide the caregiver with an objective parametric measure of how physically active their patient has been, such as walling, sitting, personal care, and feeding. The PSM will consist of three components: 1) four wireless EMG sensors, 2) a body worn transceiver (Repeater), and 3) the Base Station, which processes the signals for pattern recognition and feature extraction. The information can be sent to a remote location via telephone lines or the Internet. The specific aims of this program for Phase II are: Aim 1: To continue with Phase I development of the pattern recognition algorithms in patients with stroke; Aim 2: Design and build a working prototype of the hardware and software for the PSM; and Aim 3: Field test the prototype wireless system among stroke patients in the home environment. PROPOSED COMMERCIAL APPLICATIONS: The MA will primarily augment clinical service by making the line an effective place for rehabilitation. In addition, the PSM will have direct applicability to the field of ergonomics for work-site assessment, or in sports or recreational activities as a feedback device to facilitate training of skilled movements. Numerous other applications in the field of rehabilitation could include monitoring of drug therapies for tremor or other neuromuscular conditions, or home-exercise compliance. The knowledge base and prototypes developed in this project are directly transferable to other acquisition systems for biological signals recorded from the skin, such as EEGs and EKGs.
