Abstract
[Purpose] To investigate the relationship between motor function and the movement pattern of getting up from the floor. [Subjects] Sixty-seven community-dwelling elderly persons: age 80.3 ± 7.0 years, height 149.2 ± 6.6 cm, weight 51.2 ± 8.6 kg, BMI 23.0 ± 3.7 kg/m2. [Methods] We divided the getting up from the floor movement into 4 patterns, measured getting up from the floor ability, isometric knee extension strength, and 10m walking speed, and conducted the timed up-and-go (TUG) and functional reach (FR) tests. [Results] Multiple logistic regression analysis identified 10 m walking speed and knee extension strength as the variables which determined whether or not the arms were used in getting up from the floor. [Conclusion] When knee extension strength, FR, and TUG values are good, it is possible to perform the action of getting up from the floor, an action that is rather difficult. Furthermore, we consider that knee extension strength and 10 m walking speed are involved in whether or not the arms are used.
