在本文中，提出了一种远程监测系统，使用惯性测量单元（IMU）和鞋型地面反作用力（GRF）传感器称为智能鞋测量病人的步行数据，并通过互联网传输测量数据。在我们之前的工作中，开发了一个移动的步态监测系统，该系统基于智能鞋（用作移动的平台）测量的GRF提供视觉反馈。然而，仅智能鞋提供的有限信息可能不足以用于使用互联网的远程监控系统。在本步态康复远程监测系统中，智能鞋与IMU相结合，用于详细监测步行运动。通过分析来自IMU和智能鞋的信号、脚的轨迹、步行距离、步幅等，可以估计。一个用户友好的图形界面显示测量或估计的数据在单独的计算机在病人的位置和物理治疗师的办公室。因此，使用所提出的系统，可以通过互联网监测患者的行走运动，而不受时间或地点的限制。(C)2013爱思唯尔有限公司保留所有权利。
In this paper, a tele-monitoring system is proposed, using an inertial measurement unit (IMU) and a shoe-type ground reaction force (GRF) sensor called a Smart Shoe to measure a patient's walking data, and transmitting the measured data via the Internet. In our previous work, a mobile gait-monitoring system was developed, which provided visual feedback based on GRFs measured by a Smart Shoe (used as a mobile platform). However, the limited information provided by the Smart Shoe alone may not be adequate for a tele-monitoring system using the Internet. In the present tele-monitoring system for gait rehabilitation, a Smart Shoe is combined with an IMU for detailed monitoring of walking motions. By analyzing the signals from the IMU and the Smart Shoe, foot trajectories, walking distance, length of stride, etc., can be estimated. A user-friendly graphic interface displays the measured or estimated data on separate computers at the patient's location and the physical therapist's office. Thus, using the proposed system, it is possible to monitor a patient's walking motion via the Internet, without restrictions on time or place. (C) 2013 Elsevier Ltd. All rights reserved.
