COGNITIVE FUNCTION EVALUATION DEVICE, AND COGNITIVE FUNCTION EVALUATION METHOD AND PROGRAM

To more accurately evaluate a cognitive function of a subject.SOLUTION: A cognitive function evaluation device 1 includes a measurement base 11 for measuring a load, and a CPU 24 for evaluating a cognitive function of a subject. The CPU 24 instructs the subject to perform a predetermined foot movement on the measurement base 11 through an image display unit 30, sets a reference of a change in a load generated by the predetermined foot movement, measures a change in the load applied to the measurement base 11 by the movement performed by the subject according to the instruction, and calculates a deviation between a result of the measurement of the change in the load applied to the measurement base 11 and the set reference. The CPU 24 then evaluates the cognitive function of the subject on the basis of an extent of the calculated deviation.SELECTED DRAWING: Figure 3 【課題】被験者の認知機能をより精度よく評価する。【解決手段】認知機能評価装置１は、荷重を測定する測定台１１と、被験者の認知機能を評価するＣＰＵ２４とを備える。ＣＰＵ２４は、測定台１１上で所定の足の動作を行うことを被験者に画像表示部３０を介して指示し、所定の足の動作によって生じる荷重の変化の基準を設定し、被験者が指示に応じた動作を行うことによって測定台１１に加わる荷重の変化を測定し、測定台１１に加わる荷重の変化の測定結果と設定された基準との乖離を算出する。そして、ＣＰＵ２４は、算出された乖離の程度に基づいて被験者の認知機能を評価する。【選択図】図３
