Outline of Final Research Achievements

In order to easily and quantitatively evaluate the gait in walking rehabilitation, we have developed a reaction force measuring insole and inexpensive wireless measurement system for gait analysis. Several mechanical properties, such as compressive load, shear force and bending stress, were made to evaluate the performance of commercially available inexpensive thin-film force sensors and a new designed uniaxial shear force sensor. As a result, the accuracy for estimating and considerations upon implementation in force measurement for various daily body activities were revealed. In addition, the estimating results of ground reaction force waveform were verified experimentally over different footwear and walking pace on a group of subjects. It will be expected that a simple and inexpensive system to evaluate daily gait has been developed.
