项目摘要

It is a purpose of this study to develop the sensor system that automatically evaluates the coverage of training and presents information profitable for the gait improvement to the paralysis person is developed. Therefore, the methods of the waveform processing to the sensor that measures the leg state during the patients walking training were examined. In the sensor system, wireless communication was used to transmit the output signal from the sensor module etc. to the main system and the personal computer. The system that improved a clinical utility was able to be constructed without wiring from the sensor to use the wireless communication. Development of the wireless module was performed by the joint development with Izumi Tec Ltd.It is considered that a small and inexpensive gyroscope is useful to construct a practical sensor system in clinical. In this study, we examined the simultaneous measurement method of the lower limb joint angles and the gait phases by using the gyroscopes. From the result of the walking analysis with normal subjects, it was indicated that the sensor system could measure the joint angles with sufficient accuracy and could detect practicably the swing phase and the stance phase without mistake. Therefore, the sensing system of lower limb condition with appropriate accuracy that could be used in clinical would be constructed compactly at inexpensive by using the gyroscopes.

这项研究的目的是开发传感器系统，该系统自动评估培训的覆盖范围，并为瘫痪者的步态改善提供了盈利的信息。因此，检查了在步行训练期间测量腿部状态的传感器的波形处理方法。在传感器系统中，使用无线通信将输出信号从传感器模块等传输到主系统和个人计算机。改善临床实用程序的系统可以在没有传感器接线以使用无线通信的情况下构建。无线模块的开发是通过与Izumi Tec Ltd的联合开发进行的。这被认为是一个小而廉价的陀螺仪可用于构建临床中实用的传感器系统。在这项研究中，我们通过使用陀螺仪检查了下肢关节角度和步态相的同时测量方法。从正常受试者进行步行分析的结果，可以表明传感器系统可以足够精确地测量关节角度，并且可以无误地检测到挥杆阶段和姿势阶段。因此，可以在临床上使用的适当精度的下肢条件的传感系统将通过使用陀螺仪在廉价的临床上进行构造。
