【摘要】：偏癱患者和老年人由于某些器官受損,導(dǎo)致自身調(diào)節(jié)平衡功能低下,很容易跌倒并引發(fā)一系列影響生活質(zhì)量的問題。在患者重新達到康復(fù)的過程中,平衡能力的準(zhǔn)確檢測和評定則顯得十分重要。目前臨床均普遍采用徒手評定,就是根據(jù)一些計算量表來給患者打分。這種方法雖然比較實用,但要依賴醫(yī)師的主觀判斷,所以缺乏客觀性。本論文通過采用Microsoft Visual Studio 2010編譯環(huán)境以及C#編譯語言研制成一套人體平衡能力評測系統(tǒng),評測系統(tǒng)包括三個評測項目與十三項評測指標(biāo),供測試者在測試后通過比對本文所述的正常指標(biāo)參考范圍,檢驗被測者的平衡能力。主要工作如下:第一,設(shè)計應(yīng)用了實驗室的已有設(shè)備——力檢測平臺,它是具有三個拉壓應(yīng)變力傳感器作為硬件架構(gòu),采用ATmega128單片機作為主控芯片的嵌入式檢測系統(tǒng)。該嵌入式系統(tǒng)包括低通濾波和信號放大等功能的外圍電路。利用該系統(tǒng),實現(xiàn)了準(zhǔn)確、實時的傳感器數(shù)據(jù)采集,并用單片機內(nèi)部程序計算出人體重心的動搖軌跡坐標(biāo),通過串口發(fā)至上位機處理軟件。旨在獲得穩(wěn)定、實時的人體重心數(shù)據(jù),客觀、準(zhǔn)確分析和評價人體平衡能力。第二,本課題重點是人體平衡能力評測系統(tǒng)的軟件界面設(shè)計,采用Microsoft Visual Studio 2010編譯環(huán)境。此界面清晰直觀,也更加美觀,使用最新一代編程語言C#。多種評測項目與多種評測指標(biāo)使此人體平衡能力評測系統(tǒng)軟件功能更加豐富,讓測試者得到更符合實際情況的測試效果,并在專業(yè)的測試過程中享受更多的樂趣體驗。第三,此人體平衡能力評測系統(tǒng)的軟件界面與SQL Server 2008數(shù)據(jù)庫軟件相結(jié)合,使得測試者的測試數(shù)據(jù)都可以保存至個人專屬的數(shù)據(jù)庫,避免數(shù)據(jù)丟失和數(shù)據(jù)錯亂的意外情況發(fā)生。同時,該人體平衡能力評測系統(tǒng)的軟件界面具有打印功能,可以讓測試者在測試結(jié)束后打印出自己紙質(zhì)版的測試結(jié)果,方便測試者比對每一次測試結(jié)果的變化。第四,此人體平衡能力評測系統(tǒng)包括三項平衡能力測試,分別為睜眼測試、閉眼測試和循圓測試。通過一定數(shù)量被測者的數(shù)據(jù)采集,包括睜眼與閉眼時人體重心動搖軌跡曲線長度以及動搖軌跡包絡(luò)面積,人體重心在橫坐標(biāo)上的均值誤差和方差,人體重心在縱坐標(biāo)上的均值誤差和方差,統(tǒng)計并給出了人體平衡能力評測指標(biāo)的范圍標(biāo)準(zhǔn),可以供被測者在測試結(jié)束后檢驗自己的平衡能力。
[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.
