Human body balance assessment method and system

Abstract

The present invention provides a human body balance evaluation method, comprising: collecting the pressure center of gravity data of the body to be measured; using a multi-scale entropy algorithm to process the pressure center of gravity data to obtain the area value under the multi-scale entropy curve, and the area value is used as the The complexity of the pressure center of gravity data is used to measure the balance of the object to be measured; the center of gravity track of the pressure center of gravity data is determined, and the area of ​​the graph formed by calculating the center of gravity track is calculated to obtain the area of ​​the pressure center of gravity track, which is used to measure The balance of the object to be measured; the balance of the object to be measured is measured by the ratio of the track area to the complexity. The balance of the human body or the measured object is determined by the ratio of the trajectory area to the complexity, and the balance is calculated according to the information contained in the change of the center of gravity of the human body, so that this method overcomes the shortcomings of the linear system algorithm and the nonlinear system algorithm. , can accurately assess the balance of the human body.

Description

technical field

[0001] The invention relates to the technical field of human body balance detection, in particular to a method and system for evaluating human body balance. Background technique

[0002] At present, "complexity" is often used to analyze physiological signals in physiological medicine. Such characteristics are summarized from the dynamic model analysis and diagnostics of physiological control systems. As a result of a reduction in the individual's capacity to use, loss of complexity is considered a universal feature of pathodynamics. Entropy is the calculation of signal complexity.

[0003] Most of the existing dynamic and static pressure balance instruments only collect the data of the human body's dynamic step pressure center of gravity and standing static pressure center. The balance of the human body is only evaluated according to the ellipse and eccentricity formed by the trajectory of the center of gravity of the dynamic step. It can only be calculated...
