In the analysis of hand functions, the production and control of forces exerted during voluntary contraction of the finger muscles plays an important role; unfortunately such an analysis is rarely seen in routine clinical examinations of neurological patients. A microcomputer controlled system for the measurement and analysis of finger forces is described. The system consists of a modified Z80 based microcomputer, a commercially available high precision force transducer, a specially designed force signal amplifier and a suite of menu-driven user interactive programs. A variety of tasks is implemented by means of the computer programs. In addition to the measurement of maximum hand grip force, the system is able to record forces continuously as a function of time. Task characteristics and the type of feedback presented to the subject are under user control; they can be varied to meet clinical or experimental requirements. Examples of programs and clinical applications are presented and discussed.
在手部功能分析中，手指肌肉自主收缩时所产生和控制的力起着重要作用；不幸的是，这种分析在神经科患者的常规临床检查中很少见到。本文描述了一种用于测量和分析手指力量的微机控制系统。该系统由一台基于Z80改进的微机、一个商用高精度力传感器、一个专门设计的力信号放大器以及一套菜单驱动的用户交互程序组成。通过计算机程序实现了各种任务。除了测量最大手握力外，该系统还能够连续记录力随时间的变化。任务特性和呈现给受试者的反馈类型由用户控制；可以根据临床或实验要求进行变化。文中给出并讨论了程序示例和临床应用。
