This study intends to develop a system for managing the health of the spinal joints of elderly people who mainly live on Korean floor heating (Ondol). The spine health management system consists of a seat cushion-type posture balance device that can measure the sitting posture, an application for smart devices capable of real-time collection of posture balance data, and a database server for analysis and visualized feedback of the data. Each force signal measured with the four load cells installed in posture balance device is wirelessly transmitted to an Arduino-based Android application, and the center of pressure (COP) value of the sitting position is analyzed using the four load cell data. To test the usability of the spinal health management system, the COP values of front, back, left and right torso tilts of healthy adults in a sitting position were measured with the posture balance device and 3D motion analysis program (Visual 3D, USA). After that, the COP values were compared and analyzed. As a result of the analysis, the COP direction data (front, back, left and right) measured with the posture balance device exactly matched the direction analyzed by the 3D motion analysis system.

老年人使用压力数据中心脊柱健康管理研究

本研究旨在开发一种系统，用于管理主要以韩国地暖 (Ondol) 为生的老年人的脊柱关节健康。脊柱健康管理系统由可测量坐姿的坐垫式体位平衡设备、可实时采集体位平衡数据的智能设备应用程序、数据分析和可视化反馈的数据库服务器组成。 . 使用安装在姿势平衡装置中的四个称重传感器测量的每个力信号无线传输到基于 Arduino 的 Android 应用程序，并使用四个称重传感器数据分析坐姿的压力中心 (COP) 值。为了测试脊柱健康管理系统的可用性，前、后、使用姿势平衡装置和 3D 运动分析程序（Visual 3D，USA）测量坐姿的健康成人的左右躯干倾斜度。之后，比较和分析COP值。分析结果表明，姿态平衡装置测得的COP方向数据（前、后、左、右）与3D运动分析系统分析的方向完全吻合。
