CENTROID OSCILLATION MEASUREMENT SYSTEM

PROBLEM TO BE SOLVED: To provide a centroid oscillation measurement system capable of quantizing oscillation in a dynamic epuilibrium function test using a stabilometer.SOLUTION: A centroid oscillation measurement system includes: a force plate; a centroid coordinate acquisition means for acquiring centroid coordinates on an XY plane using load data detected by the force plate; and an analysis parameter calculation means. The centroid coordinate acquisition means acquires the centroid coordinates of a subject in an upright posture on the force plate while the subject moves the centroid according to a predetermined pattern at every prescribed interval of time. The analysis parameter calculation means includes a first calculation means for acquiring a straight line representing distribution data of the centroid coordinates in an electro-gravitogram composed of a locus of the centroid coordinates on the XY plane, in the electro-gravitogram and/or a second calculation means for acquiring the density of the distribution data of the centroid coordinates in the electro-gravitogram composed of the locus of the centroid coordinates on the XY plane, in the electro-gravitogram.
