Currently, there is a big problem of aging society in the world. So, we are developing the equipment for supporting elderly people's standing-up movement. In this report, we examined operation start timing of the experimental equipment from the movement of the center of gravity, buttocks lifting, load applied to the handrail, and grip strength of the person. As a result, the timing for operation start by grip strength has the highest evaluation point, and that by buttocks lifting evaluation has the lowest evaluation point. In the next step, we will make a quantitative evaluation and establish the control method of the supporting equipment.
