【摘要】：偏瘫患者和老年人由于某些器官受损,导致自身调节平衡功能低下,很容易跌倒并引发一系列影响生活质量的问题。在患者重新达到康复的过程中,平衡能力的准确检测和评定则显得十分重要。目前临床均普遍采用徒手评定,就是根据一些计算量表来给患者打分。这种方法虽然比较实用,但要依赖医师的主观判断,所以缺乏客观性。本论文通过采用Microsoft Visual Studio 2010编译环境以及C#编译语言研制成一套人体平衡能力评测系统,评测系统包括三个评测项目与十三项评测指标,供测试者在测试后通过比对本文所述的正常指标参考范围,检验被测者的平衡能力。主要工作如下:第一,设计应用了实验室的已有设备——力检测平台,它是具有三个拉压应变力传感器作为硬件架构,采用ATmega128单片机作为主控芯片的嵌入式检测系统。该嵌入式系统包括低通滤波和信号放大等功能的外围电路。利用该系统,实现了准确、实时的传感器数据采集,并用单片机内部程序计算出人体重心的动摇轨迹坐标,通过串口发至上位机处理软件。旨在获得稳定、实时的人体重心数据,客观、准确分析和评价人体平衡能力。第二,本课题重点是人体平衡能力评测系统的软件界面设计,采用Microsoft Visual Studio 2010编译环境。此界面清晰直观,也更加美观,使用最新一代编程语言C#。多种评测项目与多种评测指标使此人体平衡能力评测系统软件功能更加丰富,让测试者得到更符合实际情况的测试效果,并在专业的测试过程中享受更多的乐趣体验。第三,此人体平衡能力评测系统的软件界面与SQL Server 2008数据库软件相结合,使得测试者的测试数据都可以保存至个人专属的数据库,避免数据丢失和数据错乱的意外情况发生。同时,该人体平衡能力评测系统的软件界面具有打印功能,可以让测试者在测试结束后打印出自己纸质版的测试结果,方便测试者比对每一次测试结果的变化。第四,此人体平衡能力评测系统包括三项平衡能力测试,分别为睁眼测试、闭眼测试和循圆测试。通过一定数量被测者的数据采集,包括睁眼与闭眼时人体重心动摇轨迹曲线长度以及动摇轨迹包络面积,人体重心在横坐标上的均值误差和方差,人体重心在纵坐标上的均值误差和方差,统计并给出了人体平衡能力评测指标的范围标准,可以供被测者在测试结束后检验自己的平衡能力。
[Abstract]:The hemiplegic patients and the elderly suffer from the damage of some organs, which lead to low self-regulation and balance, and easily fall down and cause a series of problems affecting the quality of life. It is very important to accurately detect and evaluate the balance ability in the process of patients' recovery. At present, the clinical use of bare-hand evaluation is based on a number of computational scales to score patients. Although this method is practical, it relies on the subjective judgment of the physician, so it lacks objectivity. In this paper, a human balance ability evaluation system is developed by using Microsoft Visual Studio 2010 compiler environment and C # compiler language. The evaluation system includes three evaluation items and 13 evaluation indexes. After the test, the testers' balance ability is tested by comparing the reference range of the normal indexes described in this paper. The main work is as follows: first, the paper designs and applies the existing equipment of the laboratory, the force detection platform, which is an embedded detection system with three tension and compression strain sensors as the hardware framework and ATmega128 microcontroller as the main control chip. The embedded system includes peripheral circuits with low-pass filtering and signal amplification. By using this system, the accurate and real-time sensor data acquisition is realized, and the coordinate of the center of gravity of human body is calculated by the internal program of the single chip microcomputer, and sent to the upper computer through serial port processing software. The aim is to obtain stable, real-time human gravity data, objective, accurate analysis and evaluation of human balance ability. Secondly, this paper focuses on the software interface design of human balance ability evaluation system, using Microsoft Visual Studio 2010 compiler environment. This interface is clear and intuitive, but also more beautiful, using the latest generation of programming language C#. A variety of evaluation items and indicators make the human balance ability evaluation system more functional, so that the tester can get more practical test results, and enjoy more fun experience in the professional testing process. Thirdly, the software interface of the system and the SQL Server 2008 database software can save the test data to the personal database to avoid data loss and data mismatch. At the same time, the software interface of the system has the function of printing, which allows the tester to print out the test result of his paper version after the test, which is convenient for the tester to compare the change of each test result. Fourth, the balance ability assessment system consists of three tests: open eye test, closed eye test and circular test. Through the data collection of a certain number of subjects, including the length of the swaying trajectory curve, the envelope area of the shaking trajectory, the mean error and variance of the center of gravity of the human body in the horizontal coordinate, when the eyes are open and the eyes are closed, The mean error and variance of the center of gravity of human body in the ordinate are analyzed and the range standard of the evaluation index of the human body's balance ability is given, which can be used to test the balance ability of the person being tested after the test.
