Abstract

Many people who have gait disorder in an accident need a rehabilitation therapy, and a therapy for gait disorder is often needed in therapies. However the parts and degrees of the disorder are various, so therapists should treat it by using the most suitable methods, and the indexes such as grand reaction forces and joint angles for therapy are needed. In the therapy for gait disorder, the machine such as force sensors and optical marker systems fixed in a laboratory has been used for a long time. However, it has many restrictions to measure gait and cannot measure continuous walking in under daily life environments for a long time. Therefore we developed a wearable motion measurement device, which consists of instrumented shoes with force transducers and inertial sensors, transmitters and attitude sensors. Compared with the conventional devices, it can measure gait under a condition without restrictions, and it can be used more easily and more generally. So it is thought that it can be used to measure the gait of people with gait disorder, which is difficult to measure by using the previous devices. The objective of this research is to measure the gait of a healthy subject and a spastic paresis subject with the wearable motion measurement device, evaluate their gait characteristic quantitatively and examine whether the spastic paresis gait is discriminative or not. The result is as follows. Ground reaction forces in the anterior-posterior direction and the vertical direction can show the spastic paresis gait characteristic. Also, ankle, knee and hip joint angles can show it, too. Moreover, by checking peaks of joint angles and comparing them, therapeutic effects on people with gait disorder can be evaluated quantitatively.
