An equilibrium state analyzing apparatus, equilibrium state analysis method, program thereof and recording medium are provided that place few constraints on the degree of freedom in the area of motion or posture of the examinee. An equilibrium state analyzing apparatus includes acceleration information detector, attached to the trunk of the human body, of detecting accelerations generated in at least one direction within the horizontal plane, motion information storing device of storing the detected accelerations, and equilibrium state analyzer of analyzing the equilibrium state of the human body using the stored acceleration information.
