The research achievements supported on Grant-in-Aid for Scientific Research (C) are mainly on the following three subjects.(1) IMPROVEMENT OF THE PROTOTYPAL WALKWAY SYSTEMIn order to enhance the computational ability and the memory capacity, the computer for this system was changed to the upper level one. In consideration of durability and maintenance ability of the system, the electric circuits were assembled mostly with printed boards and cables were changed to shielded ones.(2) GAIT MEASUREMENT AND ANALYSIS THROUGH THE IMPROVED SYSTEMMaking the most of this system, some gait analysises were performed. First, walking patterns of free and under several kinds of constraint of 92 normal adults were analyzed and assessed based upon the statistics. Secondly, the gaits of normal 109 5-year-old children were studied and compared with those of adults. The development of the gait patterns according to the child's age was analyzed with respect to 75 children aged 1 to 6. Thirdly the pathological gaits of 11 cerebral palsy (C.P.) children were studied.(3) EXPLOITATION AND APPLICATION OF BIOFEEDBACK GAIT TRAINING SYSTEMWe have developed a biofeedback gait training system, which is composed of the above mentioned measuring walkway and a training walker. The distance factors are indicated on the CRT and the desired temporal factors are indicated by the tone of the buzzer sound. The adventage of this system is that it can deal with the gait problems of all subjects in any phase of rehabilitation: measurement, analysis, training, ana/or evaluation. Experimental studies were performed on patients with degenerative knee joints and resulted that the biofeedback training improved pathological gaits markedly.

科研补助金（C）资助的研究成果主要有以下三个课题：（1）原型步行道系统的改进为了增强计算能力和存储容量，将系统的计算机改为上一级计算机​​。考虑到系统的耐用性和可维护性，电路大部分采用印制板组装，电缆改为屏蔽电缆。(2)改进系统的步态测量和分析充分利用该系统，进行了步态分析。首先，对92名正常成年人的自由行走模式和多种约束下的行走模式进行统计分析和评估。其次，对109名5岁正常儿童的步态进行了研究，并与成人进行了比较。对75名1～6岁儿童的步态模式发展情况进行了分析。再次，对11名脑瘫（C.P.）儿童的病理步态进行了研究。（3）生物反馈步态训练系统的开发与应用我们开发了一种生物反馈步态训练系统，该系统由上述测量步道和训练步行器组成。距离因素在 CRT 上指示，所需的时间因素由蜂鸣器声音指示。该系统的优点在于它可以处理所有受试者在康复任何阶段的步态问题：测量、分析、训练、分析/或评估。对退行性膝关节患者进行的实验研究表明，生物反馈训练显着改善了病理步态。
