人体坐下站起过程中平衡功能评估及训练系统软件的设计与实现

Design and implementation of balance function evaluation and training system software in the process of human body standing up and sitting down

本研究针对脑卒中偏瘫患者的平衡功能定量评估的需求,设计一种针对坐下站起过程中各阶段平衡功能评估及训练的系统软件,该软件配合坐位站起平衡功能训练仪使用。软件采用面向对象编程技术,应用VS2010(Microsoft Visual Studio2010)开发平台编写,可实时获得人体在坐下站起过程中的各评估参数,包括左右臀前后最大压力、左右足底平均压力、伸展期时间、伸展前期时间、左右侧最大和平均压力及站起时的最大加速度等。结合图形和数字实时显示及虚拟现实技术,对人体坐下站起的各阶段进行平衡功能评估和训练,通过视觉、听觉反馈,使训练更具趣味性。经过测试应用,结果表明,该系统软件运行稳定可靠,具有针对性的评估并结合实时可观测的压力曲线及大量的评估参数,可使评估结果更快速更有效。

Based on the quantitative evaluation needs of balance function of stroke patients with hemiplegia,this study designed a software system which focused on the evaluation and training of balance function during the process of human body standing up and sitting down,and it was used in conjunction with the standing-up and sitting-down balance function training instrument. The software system used object-oriented programming techniques and was programmed by using the VS2010（Microsoft Visual Studio 2010） development platform. With the help of the two techniques,the system was able to obtain real time evaluating parameters during the process of human body standing up and sitting down. Specifically,the parameters included the maximum pressure on both sides of the buttock,average pressure on pelma,time period prior to extension,time period of extension,maximum and average pressure on the left and right foot,and the maximum acceleration of standing up. Balance function of human body during the standing up and sitting down process was trained and evaluated by combining graphical and digital real time display and virtual reality technology,and the training became more interesting by providing visual and audio feedbacks. The results of the application tests demonstrated the stability and reliability of this software system. The targeted assessment,combined with the real-time observable pressure curve and a large number of evaluation parameters,can make the evaluation result more rapid and effective.
