【摘要】：本研究设计开发了基于空气压差技术的减重康复步行训练系统。该系统采用比例-积分-微分控制器(PID)控制算法精确控制人体减重量,以美国德州仪器公司的混合信号处理器MSP430F149作为气压控制的核心,并使用微软公司的Microsoft Visual C++6.0开发程序设计上位机训练软件。该系统能够为下肢运动功能障碍患者提供舒适的减重步行训练环境,并能够实现对患者肌电信号的采集,以便于进一步对患者的信息进行科学、规范的管理。本文通过该训练系统对10名正常人进行下肢初始承重量、最大减重后下肢承重量、最大减重百分比等参数进行采集,分析结果显示,其组内相关系数(ICC)值均大于0.6。本文研究结果证实,该步行训练系统可靠性高,能够为临床下肢减重康复步行训练提供科学的数据。
[Abstract]:In this study, a weight-reducing rehabilitation walking training system based on air pressure difference technology is designed and developed. The system uses proportional integral-differential controller (PID) control algorithm to accurately control the weight loss of human body. The mixed signal processor (MSP430F149) of Texas Instruments is used as the core of air pressure control. And use Microsoft's Microsoft Visual C. The system can provide a comfortable training environment for the patients with lower extremity dyskinesia. And can achieve the collection of EMG signals of patients in order to facilitate the further scientific and standardized management of patient information. This paper carries out the initial weight of lower limbs of 10 normal people through the training system. After the maximum weight loss of the lower extremity weight, the maximum weight loss percentage and other parameters were collected. The results showed that the correlation coefficient (ICCC) of the group was greater than 0.6. The results of this study confirmed. The walking training system has high reliability and can provide scientific data for clinical lower limb weight-loss rehabilitation walking training.
