人体平衡能力评估方法研究及系统实现

Research on Human Balance Ability Evaluation Method and System Implementation

平衡能力的稳定性对个人保持身体稳定、维持各种身体姿势、进行各项日常活动、抵抗外界干扰并及时恢复身体稳定至关重要,因此对人体平衡能力评估系统的研究显得尤为重要。通过将平衡测试仪器方法与传统的观察法、量表评估法作对比,分析发现平衡测试仪器方法能更客观、定量、准确地反映人体平衡能力强弱。设计出一种新的评估人体平衡能力的系统,即结合传统评价指标、平均差以及方位差分析选取有效的平衡指标,基于人体重心位移测量方法,采用串口通讯以及QT界面设计技术,量化分析与评估测试者的平衡能力,并达到可视化的效果。实验结果表明:该系统可以客观、定量、精确地评估人体的平衡能力。

The stability of balance ability is very important for a person to maintain body stability,maintain a variety of body postures,carry out various daily activities,resist external interference and restore body stability in time.Therefore,the research on human balance ability evaluation system is very important.By comparing the balance test instrument method with the traditional observation method and scale evaluation method,it is concluded that the balance test instrument method can objectively,quantitatively and accurately reflect the balance ability of human body.In this paper,a new system is designed to evaluate the balance ability of human body,which combines the traditional evaluation index,mean difference and azimuth difference analysis to select effective balance index.Based on the pressure center of gravity displacement(COP)measurement method,serial communication and QT interface design technology are used to quantitatively analyze and evaluate the balance ability of the tester,and achieve the visual effect.The preliminary experimental results show that the system can objectively,quantitatively and accurately evaluate the balance ability of human body.
