Walking balance degree measuring and evaluating device and walking balance degree measuring and evaluating method

Abstract

The invention provides a walking balance degree measuring and evaluating device and a walking balance degree measuring and evaluating method. The device comprises: an acceleration sensor; an acceleration value storage device which is used for storing acceleration values collected by the acceleration sensor at each time point; a heel-grounding acceleration value generation and storage device whichis used for extracting and storing each acceleration value of a measured object when the heel touches the ground from the acceleration values stored in the acceleration value storage device; a walkingvector balance diagram generation and storage device which is used for representing the heel-grounding acceleration values which are generated and stored in the heel-grounding acceleration value generation and storage device on two-dimensional coordinates and storing the acceleration values; and a standard quantity value generation and storage device which is used for extracting the determined heel-grounding acceleration value from the heel-grounding acceleration values which are stored in the walking vector balance diagram generation and storage device, counting and calculating the acceleration values to obtain various standard quantity values and storing the standard quantity values. According to the invention, the walking balance degree can be detected and evaluated more accurately.

Description

technical field [0001] The invention relates to a walking balance measurement and evaluation device and a walking balance measurement and evaluation method, specifically according to the predetermined direction of the measured body during walking movement measured by an acceleration sensor installed on the measured body Acceleration, a device and method for measuring and evaluating the walking balance of a subject. Background technique [0002] With the decline of walking function, for example, the walking balance of the elderly or sick patients will deviate. Accurate detection and evaluation of such deviations can help provide effective rehabilitation training guidance for the elderly or sick patients. In the prior art, there is already a technology for detecting and evaluating people's walking balance, such as the technology disclosed in Japanese Patent Publication "Japanese Patent Laid-Open No. 2015-123215". The acceleration generated during walking is detected, and the ...

Problems solved by technology

[0003] Although the motion vector balance diagram has a very effective function for evaluating the walking balance of the measured object, it can only be subjectively and roughly captured in the shape of the measured object because it only uses the comparison of graphic shapes for evaluation. The walking balance of the subject, but it is impossible to accurately express the degree of walking balance, especially when comparing with the balance chart of oneself in the past, how many changes and improvements have actually been made cannot be accurately expressed by numbers (such as 30% improvement, etc.) Expression, that is, there is a problem that it is impossible to objectively express how to approach the ideal graph and the degree of improvement cannot be quantified

In addition, even if it seems to be close to the ideal figure from the motion vector balance diagram, in fact, there are still problems with the walking balance. If there are no specific figures, there will be problems where it is impossible to find the direction of improvement and the degree of improvement.
