Problems solved by technology

The disadvantage of single physiological parameter feedback is that it cannot reflect changes in the coupling relationship between systems, while the core of physical and mental state regulation is the different systems of the human body, including the cardiovascular system, respiratory system, nervous system, etc., and the systems are in a more coordinated state, that is, Enhanced coupling between systems
Feedback of a single physiological parameter, such as heart rate, skin temperature, and electrodermal feedback, is essentially to enhance the coupling degree between multiple systems of the human body and improve the coordination between systems. test taker
The adverse effects caused by this include: the skin temperature and electrodermal feedback completely rely on the subject to explore and master the relaxation skills or "heart method"; the heart rate feedback blindly requires the increase of the heart rate change caused by breathing (respiratory sinus arrhythmia) Qi), and ignore the coordination between the cardiopulmonary system, can not achieve the optimal effect, even for some patients with cardiopulmonary diseases, such as chronic obstructive pulmonary disease, heart failure patients, may induce cardiovascular events, accidents, Significantly reduces the safety and effectiveness of biofeedback techniques

Embodiment Construction

[0027] Next, the biofeedback method based on the amplitude-phase coupling analysis between signals of the present invention will be described with reference to the accompanying drawings.

[0028] Such as figure 1 As shown, the key steps of the biofeedback method based on amplitude-phase coupling between signals of the present invention are 1) obtain amplitude change information from a certain physiological signal, and obtain phase information related to the moment when feature points appear from another physiological signal ; 2) Do coupling analysis between the signal that can represent the amplitude change and the signal that can represent the phase change; 3) Control the feedback unit according to the change of the coupling strength between the signals, generate a specific biofeedback guiding signal, and improve the signal the degree of coupling between them.

[0029] The most common application mode is the coupling feedback between breathing and heart rate, such as figur...

Abstract

A biofeedback method based on amplitude and phase coupling, comprising: obtaining an amplitude change signal from a subject's physiological signal; obtaining a phase change signal from the subject's physiological signal; combining the amplitude change signal with the phase change The signals are coupled to obtain the coupling degree of the two signals, and the coupling degree is fed back to the subject.

Description

technical field [0001] The invention relates to a biofeedback method, in particular to a biofeedback method based on amplitude and phase coupling. Background technique [0002] With the aging population and the intensification of environmental pollution, various chronic non-communicable diseases, such as cardiovascular and cerebrovascular diseases, chronic fatigue syndrome, diabetes, malignant tumors, etc., have entered a high growth state in China. The first Molecular Detection and Chronic Disease Management Academic Conference held in December 2013 summarized a set of data, showing that the incidence of chronic diseases in my country is on a "blowout" trend. In order to actively respond to major health problems and challenges in my country, the former Ministry of Health launched the "Healthy China 2020" strategic research in 2008, and officially released the "Healthy China 2020" Strategic Research Report in August 2012. This national strategy aimed at comprehensively impr...
