摘　　要：设计一种集肌力测试与评定于一体的等长肌力测试仪。采用无线蓝牙通信技术,手持式肌力测试装置与上位机之间可在10 m距离范围内进行无线通信,将肌力相关的数据进行传输,由上位机对肌肉功能障碍患者不同部位的等长肌力、肌张力、峰力矩等参数进行定量检测与分析。软件采用统一的建模语言(UML),使用VC++应用软件编程,并通过开放数据库互连(ODBC)的方式,实现肌力、肌电数据同步采集和处理。对20名正常人进行初步测试,各参数的组内相关系数(ICC)均大于0.6。该仪器具有操作简便,实用性强等特点,可为临床制定康复计划和评价康复疗效提供客观的数据。This study is aimed to design a multi-functional isometric muscle strength testing system based on bluetooth communication technique. Wireless communication between portable muscle strength testing device and PC could be conducted within 10 meters to collect muscle strength related data. The collected data were transmitted to PC for isometric muscle strength, muscle tension, peak torque measurement and analysis. Software used in this system was built by unified modeling language （ UML）, VC ＋＋ and open database connectivity （ODBC）connection mode to realize the synchronization of muscle strength, EMG data collection and process. After a preliminary test of 20 healthy subjects, the result showed that intraclass correlation coefficient （ICC） was more than 0. 6. The system is easily operated and the interface is user friendly to provide reliable and objective data for clinical rehabilitation plan setting and evaluation.
