尽管目前对骨骼肌的研究越来越多,但尚未有一个可供临床检验的系统。本文利用一个代微机的系统可以计算并分析拇指收肌的力频比、舒张率、疲劳阈和耐受程度。这个可搬动的系统包括一个与线性输出霍尔效应传感器相匹配的改良的位移换能器,一个特殊设计的数据处理器及一个可以控制电刺激、程序单和人—机对话程序的微机。从对100名健康自愿受试者的试验中,得到了能与外科营养不良患者相比较的正常的基础数据。与其它系统相比,该系统可以客观地计算骨骼肌的功能,并提供一种更精细的评价耐受程度的方法。
Although there is a growing body of research on skeletal muscle, there is no system available for clinical testing. In this paper, a computer-based system can calculate and analyze the force-frequency ratio, diastolic rate, fatigue threshold and degree of tolerance of the thumb muscles. The moveable system includes an improved displacement transducer that matches the linear output Hall-effect sensor, a specially designed data processor, and a microcomputer that controls the electrical stimulation, programming and human-machine dialogs. From trials of 100 healthy volunteers, normal baseline data were obtained that were comparable to those of surgical malnutrition. Compared with other systems, the system can objectively calculate the function of skeletal muscle and provide a finer way to evaluate the degree of tolerance.
