Problems solved by technology

[0005] However, in the related art, the measurement and the estimation of the degree of disease are performed on the assumption that the subject keeps walking, so it is difficult to estimate the walking condition and the risk of falling in a short time from the start of walking
In addition, techniques implemented in medical practice have the problem that the subject is dangerous and feels burdened because the subject is required to perform actions that require balance ability

Abstract

According to an embodiment, a gait analysis device includes a measuring unit configured to measure a subject's motion; a determining unit configured to determine a walking start point in time at which the subject starts walking based on the subject's motion; a feature quantity calculator configured to, when the walking start point in time is determined, calculate a feature quantity of the subject's motion measured during a predetermined time period starting from the walking start point in time as a time period in which the subject's motion is not stabilized; and an estimating unit configured to estimate a subject's walking condition based on the feature quantity.

Description

[0001] Cross References to Related Applications [0002] This patent application is based on and claims priority from Japanese Patent Application No. 2011-238246 filed on October 31, 2011; the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments described herein generally relate to gait analysis devices. Background technique [0004] Devices for evaluating gait motion using various sensor devices have been developed for the purpose of observing the course of a disease, preventing falls, and the like. In medical practice, subjects are asked to perform actions requiring balance (standing on one foot, etc.), and their behavior is observed to determine fall risk. [0005] However, in the related art, the measurement and the estimation of the degree of disease are performed on the assumption that the subject keeps walking, so it is difficult to estimate the walking condition and the risk of falling in a short time from the start of ...
