1. A motor function evaluation device comprising:
a measurement base;
a load measurement circuit configured to measure load change over time of a subject applied to the measurement base; and
an arithmetic circuit configured to determine a balance ability indicator of the subject determined by the load change over time measured by the load measurement circuit, wherein:
the arithmetic circuit is configured to determine the balance ability indicator based on a stabilizing time period, within which variation of the load measured by the load measurement circuit is stabilized, and
the stabilizing time period is measured from a time when the subject stands up from a sitting position on a chair and the load applied to the load measurement circuit becomes a maximum value until a time when the variation of the load is stabilized.
