PROBLEM TO BE SOLVED: To provide a gait analysis device that can estimate a walking state in a short time.SOLUTION: A gait analysis device has a determination unit 42, a feature value calculation unit 460 and an estimation unit 48. The determination unit 42 determines a walking start time when a subject starts walking, based on the acceleration measured by a measuring unit 40 worn by the subject. The feature value calculation unit 460 calculates at least any one of acceleration feature values of: the acceleration in the vertical direction of the subject measured by the measuring unit 40 during a predetermined period from the walking start time as a period when the movement in the walking of the subject does not become routine, when the walking start time is determined; and the acceleration in the horizontal direction substantially perpendicular to the traveling direction of the subject. The estimation unit 48 identifies the walking state of the subject, based on the feature value calculated by the feature value calculation unit 460. |
