PROBLEM TO BE SOLVED: To easily judge physical capabilities in terms of walking of a subject person.SOLUTION: A trajectory calculating part 135 in a part 131 for calculating a trajectory of the center of gravity calculates a trajectory of positions of the center of gravity of the subject person in a state of making a rotating movement or moving a body to describe an inverted cone by using feet as the center on a pressure distribution sensor 11. An extracting part 142 of a stable contour extracting part 141 extracts a stable contour being a closed curve on the pressure distribution sensor 11 from the trajectory of the positions of the center of gravity.COPYRIGHT: (C)2010,JPO&INPIT【課題】被計測者の歩行に関する運動能力を容易に判断する。【解決手段】重心軌跡算出部131の軌跡算出部135が、圧力分布センサ11上におけるローテーション動作状態の被計測者の重心位置の軌跡を算出する。安定輪郭抽出部141の抽出部142が、重心位置の軌跡に基づいて、圧力分布センサ11上において閉曲線となる安定輪郭を抽出する。【選択図】図2
