Abstract
Humans are the only living things which make a erect bipedalism. They are evolving the leg extremity-below a pelvis, and gained the more complicated and more sophisticated walk system. In the depertment of the bio-mechanics or the rehabilitation, movement analysis instrument has been developed. But, almost of these are attended by the feeling of a constraint, or a measurement place will be limited. We makes the measurement suit which can survay operation of the leg, without giving a feeling of a restraint as much as possible as an experiment. And the in-sole sensor shoes, used for it, are developed.
