Three people participated in the experiment, an elderly female (she could not stand up easily), healthy elderly and young males. Their standing-up motion from a chair was observed by using infrared cameras and force plates. The young and elderly males stood up rapidly and dynamically without over-bending whereas the elderly female stood up slowly and statically with over-bending due to decline of muscle strength. In addition, the standing-up motion for the elderly female was unstable in comparison with that for other two subjects. As factors causing the instability of standing-up motion, the position of the body and knee stability were focused. Bending the body forward during standing-up destabilized the motion. The knee sway during standing-up for the elderly female was greater than that for other two subjects. The stability of standing-up motion for the elderly female was well improved by wearing knee supporters since the knees became stabilized.
