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。This research is to develop a weight-loss walking rehabilitation training system based on differential air pressure. The system adopted Proportion-Integral-Derivative （PID） algorithm to improve the precision of weight loss, taking MSP430F 149 microprocessor of Texas Instruments as the core of pressure control system. The training software is designed based on Microsoft Visual C＋＋ 6.0 of Microsoft. The system can provide comfortable training environment for patients with lower limb motor function impediment, and can collect electromyographic signals from patients, so as to further the scientific and normative management of the patient＇s information. Based on this training system, the initial bearing weight, bearing weight after maximum weight loss, and maximum weight loss percentage of 10 normal adults＇ lower limbs were collected. It was found that the intraclass correlation coefficient （ICC） values were all greater than 0.6. The training system has a good reliability, which can provide scientific data for clinical weight-loss lower limb rehabilitation training.
