PROBLEM TO BE SOLVED: To estimate the actuating force of a locomotorium relating to body motion in daily life of a subject.SOLUTION: A locomotorium actuating force estimation system includes: a body parameter information input part 10 for receiving body parameter information of a body region of a subject; a body parameter information allocation part 20 for allocating the body parameter information of the body region of the subject to a corresponding body region of a virtual human body model; a moment of inertia calculation part 30 for calculating the moment of inertia of the body region of the virtual human body model; a body motion measurement part 40 for measuring body motion in daily life of the subject; a locomotorium actuating force calculation part 50 for calculating joint torque of a body region relating to body motion in a daily life of the virtual human body model on the basis of a calculation result of the moment of inertia of the body region of the virtual human body model, and a measurement result of the body motion in the daily life of the subject; and a locomotorium actuating force output part 60 for estimating the joint torque as actuating force of the locomotorium relating to body motion in the daily life of the subject and outputting the actuating force.SELECTED DRAWING: Figure 1
