Improvement study for measurement accuracy on wireless shoe-type measurement device to support walking rehabilitation
2012
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. From evaluation to first trial manufacture, it was found that our system was effective to let the patients, physicians and physical therapists know quantitative gait information. However, it was also found that there were some problems such as insufficient measurement area. Then, hardware of device was redesigned to enlarge measurement area but measurement accuracy decreased. Therefore, improvement method which could decrease measurement error was proposed and the efficacy of proposition was revealed by experimental results.
