PROBLEM TO BE SOLVED: To provide a gait balance evaluation device capable of evaluating gait balance of a measurement object person without depending on a situation of the measurement object person.SOLUTION: A gait balance evaluation device according to the present invention comprises: an acceleration sensor for measuring a waveform representing an acceleration of motion of a trunk of an object person in a vertical direction a load sensor for measuring a waveform representing a load applied to a foot of the object person and calculation means that, for a waveform representing the acceleration measured by the acceleration sensor and a waveform representing the load measured by the load sensor, generates a waveform that is a real number multiple of a displacement of one waveform from an average value of the one waveform, calculates a differential value to become minimum when the generated waveform is overlapped with the other waveform, and calculates a coincidence rate between the generated waveform and the other waveform higher as the differential value is smaller.COPYRIGHT: (C)2015,JPO&INPIT【課題】測定対象者の状況に関わらず測定対象者の歩容のバランスを評価可能な歩容のバランス評価装置を提供すること。【解決手段】本発明にかかる歩容のバランス評価装置は、対象者の体幹の上下方向への動作の加速度を示す波形を測定する加速度センサと、対象者の足にかかる荷重を示す波形を測定する荷重センサと、前記加速度センサが測定した前記加速度を示す波形及び前記荷重センサが測定した前記荷重を示す波形に関して、一方の波形について当該一方の波形の平均値からの変位を実数倍した波形を生成し、生成した波形と他方の波形とを重ね合わせたときの差分値が最小となるような差分値を計算して、当該差分値が小さいほど当該生成した波形と当該他方の波形との一致率を高く計算する計算手段と、を備える。【選択図】図1
