Abstract

The invention provides a human body balance estimation method. The human body balance estimation method comprises the steps of acquiring pressure center-of-gravity data of a body to be measured; adopting a multi-scale entropy algorithm to process the pressure center-of-gravity data to obtain an area value under a multi-scale entropy curve, wherein the area value is used as the complexity of the pressure center-of-gravity data and is used for measuring the balance of the body to be measured; determining the center-of-gravity track of the pressure center-of-gravity data and calculating the areaof a graph formed by the center-of-gravity track to obtain a pressure center-of-gravity track area, wherein the pressure center-of-gravity track area is used for measuring the balance of the body to be measured; measuring the balance of the body to be measured through the ratio of the track area to the complexity. Through the ratio of the track area to the complexity, the balance of the human bodyor the measured body is determined, specifically, according to information included in the change of the center of gravity of the human body, the balance is calculated, so that the method overcomes the defects of a linear system algorithm and a nonlinear system algorithm, and the balance of the human body can be accurately estimated.

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...
