PROBLEM TO BE SOLVED: To provide a method of measuring muscle while not giving stress to an experimental animal during measurement by utilizing the instinctive behavior of the experimental animal such as a mouse or a rat.SOLUTION: The method for measuring the muscle of a subject includes: a step of engaging the subject and a muscle measuring member by a connection member in order to measure the muscle of four limbs while reducing the stress to be given to an animal which is the subject a step of introducing the subject into a cylindrical member for housing the subject and a step for measuring the muscle of the subject by moving the subject in the cylindrical member to the opposite side of the muscle measuring member. The muscle measurement device of the subject includes: the cylindrical member for housing the subject the muscle measuring member for measuring the muscle of the subject and the connection member for engaging the subject and the muscle measuring member.COPYRIGHT: (C)2013,JPO&INPIT【課題】マウス・ラットなどの実験動物の本能的な習性を利用して、測定時に実験動物に対してストレスを与えないようにしながら、筋力を測定する方法を開発する。【解決手段】被検体である動物に与えるストレスを軽減しつつ四肢の筋力を測定するために、被検体と筋力測定部材とを連結部材により係合する工程;被検体を収容する筒状部材中に被検体を導入する工程;被検体が筒状部材中を筋力測定部材とは反対側に移動させることにより、被検体の筋力を測定する工程;を含む、被検体の筋力を測定するための方法。被検体を収容する、筒状部材;被検体の筋力を測定する、筋力測定部材;そして被検体と筋力測定部材とを係合する、連結部材;を含む、被検体の筋力測定装置。【選択図】図1
