Abstract
It is important to evaluate walking ability quantitatively in order to solve the problem of extended nursing dependency in the elderly community. Efficient rehabilitation can be made possible and a care worker's burden can be reduced. In our study, we measure the movable range and speed of the legs in motivative exercise and extract parameters that are related to walking ability. Moreover, we measure muscle function of the leg with an electromyogram and consider a relationship between muscle function and walking ability.
