Recently, medical treatment for intractable diseases attended with disorders of the motor function such as Parkinson syndrome, cerebellar ataxia, muscular dystrophy, apoplexy, and so on has become of general interest. In order to diagnose these diseases efficiently in an early stage, a new method of examining the human motor function should be developed. The major purpose of our researches is to develop a new examination system of the motor function using the 2-dimensional manual control system so that we can quantitatively evaluate medical therapy or rehabilitation and make an automatic diagnosis by using a personal computer system.First, several experiments in the 1-dimensional manual control system have shown the effects of two central nervous system diseases, i.e. Parkinsonism and cerebellar ataxia, on the predictive control function of voluntary movements. This has indicated that the learning process, the power spectrum of rate of the manipulated variable and the coherency functio … More n can become useful parameters to make a diagnosis for discriminating the diseases.Moreover, we have studied human adaptability to the reference input in the manual control system and shown that the proposed model realizing output regulation for a linear system with delay can approximate the frequency response which cannot be explained easily by usual models.Using the experiments in the 2-dimensional manual control system in which either the horizontal polarity or the vertical one of the controlled object is reversed, we have shown that the control characteristics of the human operator have anisotropy with respect to the reverse direction of the controlled object.The system proposed in this study can make an objective and quantitative examination of the integration function of visual and somatic sensations which cannot be carried out by any other neurological tests and could give a more practical and effective examination method by introducing some computer algorithms for an automatic diagnosis.

近年来，帕金森综合征、小脑性共济失调、肌营养不良、中风等伴有运动功能障碍的顽固性疾病的医学治疗已成为人们普遍关注的问题。为了在早期有效地诊断这些疾病，需要开发一种新的检测人体运动功能的方法。本研究的主要目的是利用二维手动控制系统开发一种新的运动功能检测系统，以便利用个人计算机系统对医学治疗或康复进行定量评估和自动诊断。首先，在一维手动控制系统中的几个实验表明，帕金森病和小脑性共济失调这两种中枢神经系统疾病对随意运动的预测控制功能的影响。这表明，学习过程、被操纵变量的速率功率谱和…的一致性函数本文还研究了人工控制系统中人类对参考输入的适应性，证明了所提出的实现线性时滞系统输出调节的模型能够逼近通常模型难以解释的频率响应。在被控对象水平或垂直极性反转的二维人工控制系统中进行的实验表明，研究表明，操作者的控制特性相对于被控对象的反向具有各向异性，本研究提出的系统可以对视觉和躯体感觉的整合功能进行客观、定量的检测，这是任何其他神经学测试都无法完成的，通过引入一些计算机算法进行自动诊断，可以给出一种更实用、更有效的检测方法。较少
