Development of Measuring Walkway for Temporal and Distance Factors of Gait and Its Clinical Application

科研资助项目(C)资助的研究成果主要集中在以下三个方面：(1)原型步道系统的改进为了提高系统的计算能力和存储容量，将该系统的计算机改为上位机。考虑到系统的耐用性和维护能力，电路大多采用印制板组装，电缆改为屏蔽电缆。(2)通过改进系统进行步态测量与分析，充分利用该系统进行了步态分析。首先，在统计的基础上，对92例正常成人自由行走和几种约束下的行走方式进行了分析和评价。其次，对109名5岁正常儿童的步态进行了研究，并与成人步态进行了比较。对75名1至6岁儿童的步态模式发展情况进行了分析。再次对11例脑瘫患儿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道组成。距离因素在CRT上显示，所需的时间因素由蜂鸣器声音的音调表示。该系统的优点在于，它可以处理所有受试者在康复的任何阶段的步态问题：测量，分析，训练，ana/或评估。对退行性膝关节患者进行了实验研究，结果表明生物反馈训练明显改善了病理性步态。

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.
