Abstract
The purpose of this study was to clarify factors influencing the presence or absence of getting down on allfours on standing up from the floor. In 47 elderly female residents, we evaluated the grip strength, muscular strength of the quadriceps muscle of the thigh, foot grasp power, sit-ups, sit-and-reach distance, and duration of standing on one leg. We examined factors involved in getting down on all fours on standing up from the floor using logistic regression analysis. As a factor involved in getting down on all fours on standing up, sit-ups were selected. These findings suggest that the muscular strength ofthe trunk is related to the presence or absence of getting down on all fours on standing up from the floor in elderly persons. Those in whom the muscular strength of the trunk is stronger may stand up without getting down on all fours.
