【摘要】：平衡功能是人体为保持全身处于稳定状态而抵抗破坏平衡的自身因素和外力的一项非常重要的身体功能,它直接影响人体正常的运动功能和日常活动能力。因此人体平衡能力是评价人体身体状况的一项重要指标。平衡能力可以分为静平衡和动平衡。本研究主要针对动平衡能力的测量。动平衡是指通过应对由于身体一部分或者整个身体的动作产生的各种力而维持的姿态,它包括人体进行各种自主姿势间转换重新获得稳定状态和对外界干扰及时做出反应而达到平衡状态,这两个方面的内容。本系统采用六轴陀螺加速度传感器对平衡板的倾斜角进行跟踪记录,再通过STM32微控制器对陀螺仪和加速度数据进行角度融合,上位机将接收到的数据进行实时显示和绘图,便于测试。本系统利用准确获取的实时倾角信息作为人体动平衡能力评价的参数。它可以设定多种测量模式,如主动维持水平和跟随摆动,睁眼状态和闭眼状态下的测量等,从而更加全面的对人体动平衡能力进行评价。经过试验验证,利用本系统进行动平衡测试,选取的指标结果具有统计学意义；平衡角度标准差、平均角速度等指标具有良好的重测信度；最后给出了动态跟随测试的综合评价方法,综合得分与跟随曲线基本一致,但是此方法的科学性与合理性还需要进一步的验证。虽然,本系统在评价人体动平衡能力的性能方面还需要大量科学准确的数据库支持,但是本系统可以作为体育运动中有关动平衡项目的辅助训练方法和平衡相关疾病的康复训练手段；相信本系统也对更加完备的动平衡能力测量仪器开发具有重要意义。
[Abstract]:Balance function is a very important physical function of the human body to resist the internal factors and external forces that destroy the balance in order to keep the whole body in a stable state. It directly affects the normal movement function and daily activity ability of the human body. Therefore, the balance ability of human body is an important index to evaluate the human body condition. The balance ability can be divided into static balance and dynamic balance. A measure of the ability to balance. Dynamic balance is a posture maintained by responding to various forces generated by the actions of a part of the body or the body as a whole. It includes a variety of autonomous posture changes between the human body to regain stability and timely response to external interference to achieve balance. This system uses six-axis gyroscope acceleration sensor to track and record the tilt angle of the balance plate, and then integrates the gyroscope and acceleration data by STM32 microcontroller. The upper computer can display and plot the received data in real time, which is convenient for testing. The system uses the accurately acquired real-time inclination information as the parameter for evaluating the human body's dynamic balance ability. It can set up various measuring modes. Such as actively maintaining the level and following the swing, the state of open eyes and the state of closed eyes, and so on, so as to evaluate the dynamic balance ability of the human body more comprehensively. After experimental verification, the system is used to carry out the dynamic balance test. The results of the selected indexes have statistical significance; the standard deviation of equilibrium angle and the average angular velocity have good test-retest reliability; finally, the comprehensive evaluation method of dynamic follow test is given, and the comprehensive score is basically the same as the following curve. However, the scientific and reasonable nature of this method needs further verification. Although, this system still needs a large number of scientific and accurate database support in evaluating the performance of human dynamic balance ability. However, the system can be used as an auxiliary training method in sports about dynamic balance items and a rehabilitation training method for balancing related diseases, and it is believed that this system is also of great significance to the development of more complete measuring instruments for dynamic balance ability.
