Embodiment approach

[0094] Below, based on figure 1 The cognitive function evaluation system according to this embodiment will be described.

[0095] figure 1 It is a block diagram showing the configuration of the cognitive function evaluation system according to the embodiment of the present invention.

[0096] figure 1 The cognitive function evaluation system shown includes a cognitive function evaluation device 1 , a camera 2 , and a display unit 3 .

[0097] Camera 2 images a walking test subject. The camera 2 outputs moving image data representing a walking test subject to the cognitive function evaluation device 1 . The camera 2 is connected to the cognitive function evaluation device 1 by wire or wirelessly.

[0098] The cognitive function assessment device 1 includes a processor 11 and a memory 12 .

[0099] The processor 11 is, for example, a CPU (Central Processing Unit), and includes a data acquisition unit 111 , a walking parameter detection unit 112 , a cognitive function deter...

Abstract

The invention provides a cognitive function evaluation method in a cognitive function evaluation device that evaluates a cognitive function based on a walking motion of a subject, a cognitive functionevaluation device and a storage medium. The cognitive function evaluation method includes: acquiring walking data related to walking of the subject; detecting, from the walking data, at least one ofan angle of an ankle joint of one foot and an angle of a knee joint of one leg of the subject; and determining a cognitive function level of the subject using at least one of the angle of the ankle joint and the angle of the knee joint. According to the configuration of the present invention, cognitive functions can be evaluated simply and with high precision.

Description

technical field [0001] The present invention relates to a technique for evaluating cognitive function based on a test subject's walking action. Background technique [0002] In recent years, in order to understand the health status of the elderly, technologies that can easily estimate body functions are being developed. [0003] In particular, a technique for assessing cognitive or motor functions based on parameters measured from routinely performed walking is proposed. [0004] For example, Japanese Patent Laid-Open Publication No. 2013-255786 discloses a method of estimating susceptibility to geriatric disorder (risk of geriatric disorder) based on walking parameters measured in walking behavior. [0005] Also, for example, International Publication No. 2018 / 066422 discloses a cognitive function assessment device that includes: a reference memory indicating the relationship between the periodicity of a person's body movement when walking and the degree of a person's cogn...
