PROBLEM TO BE SOLVED: To provide a physical function determination method which is more practical.SOLUTION: A determination method comprises a step for measuring thickness of a flexor digitorum superficialis muscle and a flexor digitorum profundus muscle as a muscle amount, a step for measuring a grasping power as a muscle power, a step for dividing the muscle power by the muscle amount for determining a value, and a step for determining a physical function using the obtained value.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】より実用的な身体機能の判定方法を提供する。【解決手段】この判定方法は、浅指屈筋と深指屈筋とを併せた厚さを筋量として測定する過程、握力を筋力として測定する過程、筋力を筋量で除して値を求める過程、上記値を用いて身体機能を判定する過程を含む。【選択図】図4
