This study aimed to clarify the factors that determine the mobility of elderly subjects
who participated in preventative care classes. Thirty-six subjects aged 65 years and
above who participated in preventative care classes were included. There were five
parameters: age at the time of participation, motor imagery test for children (N-type
test), single leg stance test, 30-second chair-stand test (CS-30), and Timed Up and
Go test (TUG). Next, multiple regression analyses were performed using the forced
entry method, with TUG as the dependent variable and the other parameters as
independent variables, and the relationship with TUG was investigated. Moreover,
multiple regression analyses were performed using the stepwise method. As a result,
the standardization coefficient of the N-type test was the highest as a factor related
to TUG. In addition, the N-type test and CS-30 were selected for multiple regression
analyses using the stepwise method. The obtained multiple regression equation was
TUG (seconds) = -0.560 × (N-type test) -0.214 × (CS-30) + 23.689. The multiple
correlation coefficient (R) was 0.81, coefficient of determination (R2) was 0.655, and
adjusted coefficient of determination (R2) was 0.635. Based on the above, the mobility
of elderly subjects who participated in the preventative care classes was most closely
related to the N-type test. Furthermore, it was suggested that the mobility of the
elderly subjects who participated in the preventative care classes could be predicted
using the N-type test and CS-30.
