Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Such as figure 1 As shown, a kind of balance ability detection method based on nonlinear technology provided by the present invention comprises the following steps:

[0048] 1) Record the position of the center of gravity of the human body to obtain the offset d of the position of the center of gravity of the human body, specifically:

[0049] 1.1) can be used as figure 2 As shown in the rectangular platform, pressure sensors are arranged on the four corners of the rectangular platform, and the pressure signal w when a person stands in the middle of the rectangular platform is collected by the pressure sensor 1 、w 2 、w 3 、w 4 ,(w 1 、w 2 、w 3 、w 4 represent the pressure values ​​of the left front, left rear, right rear, and right front respectively), the sampling rate of the pressure signal is above 100Hz, and the samp...

Abstract

The invention discloses a balance ability detection method and device based on a nonlinear technology. The method includes the steps: firstly, recording the gravity center of a human body to obtain the offset d of the gravity center of the human body; secondly, ranking the offset d according to sampling time to obtain a sequence D (d1, d2, ..., dL); thirdly, sequentially tracing L-1 human body gravity center offset change Poincare points by taking two d values at adjacent sampling time as a horizontal coordinate and a vertical coordinate to obtain a sequence P (p1, p2, ..., pL-1); fourthly, projecting the sequence P (p1, p2, ..., pL-1) along a straight line y=x and a straight line y=-x, and calculating dispersion degrees to obtain an evaluation index representing balance ability long-duration adjusting ability and an evaluation index representing balance ability short-duration adjusting ability. The balance ability of the human body can be effectively evaluated, and a reliable tool isprovided for evaluating the balance ability of the human body.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and relates to a method and device for detecting balance ability based on nonlinear technology. Background technique [0002] Human balance ability is the basic condition for carrying out various daily activities. With age, various body functions related to balance will decline, such as weakened muscle strength, vision loss, and prolonged reaction time, which will lead to a decline in the balance of the elderly, increase the risk of falls, and cause serious injury, and even death. [0003] Traditionally, the evaluation of balance ability adopts methods such as clinical observation and scale evaluation. Doctors can obtain impressions by observing the balance performance of subjects under different conditions, such as observing sitting, standing, and standing with two feet in parallel when eyes are open and eyes closed Wait for the body shaking in postures or ask for ratings, etc. The ...
