A purpose of this study is I am biodynamical, and to make a posture control structure of the movement to wipe buttocks in the cerebral apoplexy hemiplegia clear. In addition, I limited the person of object because the obstacle image of the cerebrovascular accident was complicated. The support characteristics of paralysis side lower limbs are low this time, and monitor examines a person of sibgle paralysis of a necessary level in real movement. As a result, the characteristic of the movement to wipe buttocks was to control posture by letting a Trunk side moment and the hip joint extorsion moments of the side to wipe increase. It was to centralize a change of the working weight feeling in the non-paralysis side lower part, and it was it with a movement method to reduce unrest of the weight feeling to be concrete. In addition, I triggered it for braking for sagittal plane by generating a knee joint extension moment greatly at the same time. The movement of the cerebral apoplexy hemiplegia was different from the movement to unfold effectively of the physically unimpaired person and made much of safety most as things mentioned above
