Walking balance evaluating method and device and walking balance monitoring method and system

Abstract

The invention relates to a walking balance evaluating method and a walking balance evaluating device, and a walking balance monitoring method and a walking balance monitoring system. The walking balance evaluating method comprises a receiving step, a time domain-frequency domain transformation step, a synthetic harmonic distortion rate calculating step, an evaluating step and an outputting step, wherein the receiving step comprises an operation receiving acceleration data of the waist, the left foot and the right foot of a human body in x, y and z directions obtained by detecting accelerations of the waist, the left foot and the right foot in real time; the time domain-frequency domain transformation step comprises an operation of transforming the acceleration data of the waist, the left foot and the right foot in the x, y and z directions into frequency spectrum data of the waist, the left foot and the right foot in the x, y and z directions; the synthetic harmonic distortion rate calculating step comprises operations of resolving dominant frequency components and harmonic components of the frequency spectrum data of the waist, the left foot and the right foot in the x, y and z directions, calculating harmonic distortion rates of various frequency spectrum data on the basis of the resolved dominant frequency components and harmonic components of the various frequency spectrum data, and acquiring a synthetic harmonic distortion rate on the basis of the harmonic distortion rates of the waist, the left foot and the right foot in the x, y and z directions; the evaluating step comprises an operation of evaluating a walking balance capacity in accordance with the synthetic harmonic distortion rate; and the outputting step comprises an operation of outputting a result evaluated in the evaluating step.

Description

technical field [0001] The invention relates to a technology for monitoring the balance ability of a human body and its changes during walking, in particular to a walking balance evaluation method and device, a walking balance monitoring method and system, and a wearable human body balance monitor. Background technique [0002] Due to aging, disease, long-term medication and other reasons, the balance function of the elderly gradually degenerates, and bad movements in walking often occur, and the risk of falling is gradually increased. The process of degeneration of balance function varies from person to person. There is no one-size-fits-all time point. The elderly often do not understand their own physical condition. The gait is out of balance, resulting in a tragic fall. If a scientific method can be found to parse out the balance password of the human body and develop an indicator to continuously convert a person's balance state through real-time walking posture data, it...

AI Technical Summary

Problems solved by technology

Instrument measurement is more objective, but like the scale method, it still measures some indirect indicators, and because the equipment is bulky and expensive, it is very difficult to popularize it

In addition, the test of a specific scene in the laboratory is not a true performance of the balance ability in daily walking. Therefore, it does not solve the problem of normalization, convenience, and no interference with the daily activities of the testee, directly testing the balance ability of the human body in real situations.
