Biological feedback method based on amplitude and phase coupling

Abstract

The invention provides a biological feedback method based on amplitude and phase coupling. The biological feedback method comprises the following steps: acquiring amplitude change signals from physiological signals of a tested person; acquiring phase change signals from the physiological signals of the tested person; and coupling the amplitude change signals and the phase change signals, thus obtaining the coupling degree of the two paths of signals, and feeding the coupling degree back to the tested person.

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...

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
