Improvement Research of Shoe-Type Measurement Device for a Walking Rehabilitation Support System

We have developed a shoe-type measurement device which is able to measure gait information such as step length, width and pressure distribution while daily living. We hypothesized that a walking rehabilitation system could be realized by combining shoe-type device and comprehensively display which showed analytical results for gait with real time operation. In this paper, based on the previous researches, real time operation for foot position measurement was realized by improving hardware and software. However, measurement error became larger than that in offline operation. The reason was thought to be time difference in synchronization which was necessary to realize wireless measurement system. By considering time difference, most measurement errors became smaller. In the next research, it would be necessary to decide time difference in any communication condition.
