项目摘要

 DESCRIPTION (provided by applicant): The goal of this project is to develop and evaluate a new system called GaitRF that can measure walking speed and other detailed gait parameters passively within the home. The ability to move is a critical function that underlies the quality of life for elders as well as those suffering from neurologic or physical ailments. Changes in aspects of gait such as walking speed, stride length, stride imbalance, etc. have been shown to correlate with changes in physical and cognitive health. Gait is typically measured periodically within a clinical setting. In-home monitoring offers the advantage of continuous and ongoing measurements providing significantly more information about changes in a patient's health under real life conditions. Ongoing accurate estimation of gait within the home can help to guide caregivers about the need for transitioning older adults to higher levels of care. Accurate in-home gait monitoring also has the potential to encourage older adults to maintain independence later into their lives by enabling family members and friends to monitor health status remotely. The proposed system makes use of novel wireless technology being developed at EmbedRF. An array of tiny transceivers are positioned in either a hallway or doorframe and configured to wirelessly send radio frequency (RF) signals between each other. As a person walks past the transceivers, their body disrupts the RF signal strength allowing for the estimation of gait metric without the need for the person to wear any monitoring device. Preliminary results using only 2 or 4 transceivers have already demonstrated the ability to accurately estimate walking speed. Preliminary results also show the unique ability to discriminate between individuals for use in a multi-resident home or to exclude data when a caregiver or friend visits. Specific aims in this proposal will 1) further develop prototype systems for walking speed estimation using transceiver pairs, 2) research and develop use of an array of sensors placed at base-board height in order to extract more detailed gait metrics; a second transceiver pair will be placed at approximate head height to provide multi-person discrimination capability, and 3) perform preliminary in-home evaluations of the GaitRF system. Advanced machine learning and tracking algorithms will be utilized to process the RF signals to extract gait metrics. We will evaluate the performance of GaitRF in both a laboratory setting and within single-resident and multi- resident homes of seniors. If successful, this new system has the advantage of being low-cost, unobtrusive, and easy to install, while still providing accurate and detailed gait metrics. The system can be used as a stand-alone gait monitor or incorporated into more general health monitoring systems. Application of the technology will support independent living and may also be used in clinical trials of drugs or procedures that affect mobility.
 描述(由申请人提供):该项目的目标是开发和评估一种名为GaitRF的新系统,该系统可以在家中被动测量步行速度和其他详细的步态参数。移动的能力是一个关键的功能,它是质量的基础。 为长者及患有神经系统或身体疾病的人士提供更佳的生活质素。步态方面的变化,如步行速度、步幅、步幅不平衡等,已被证明与身体和认知健康的变化相关。步态通常在临床环境中定期测量。家庭内监测提供了连续和正在进行的测量的优点,其提供了关于患者在真实的生活条件下的健康变化的显著更多的信息。对家中步态的持续准确估计可以帮助指导护理人员将老年人过渡到更高水平的护理。准确的家庭步态监测也有可能通过使家庭成员和朋友远程监测健康状况来鼓励老年人在以后的生活中保持独立。 该系统利用了EmbedRF正在开发的新型无线技术。一个微型收发器阵列位于走廊或门框上,并被配置为在彼此之间无线发送射频(RF)信号。当人走过收发器时,他们的身体会扰乱RF信号强度,从而可以估计步态指标,而无需佩戴任何监测设备。仅使用2或4个收发器的初步结果已经证明了准确估计步行速度的能力。初步结果还显示了在多居民家庭中区分个人或在护理人员或朋友来访时排除数据的独特能力。本提案的具体目标是:1)进一步开发使用收发器对进行步行速度估计的原型系统; 2)研究和开发放置在基板高度的传感器阵列的使用,以提取更详细的步态指标;第二个收发器对将放置在近似头部高度,以提供多人识别能力; 3)对GaitRF系统进行初步的家庭评估。将利用先进的机器学习和跟踪算法来处理RF信号,以提取步态指标。我们将评估 GaitRF在实验室环境中以及在老年人的单居民和多居民家庭中的性能。 如果成功,这种新系统具有低成本、不显眼、易于安装的优点,同时仍然提供准确和详细的步态指标。该系统可以用作独立的步态监测器或并入更一般的健康监测系统。该技术的应用将支持独立生活,也可能用于影响移动性的药物或程序的临床试验。
