Embodiment Construction

[0040] like figure 1 As shown in the figure, the mental state detection method of Taiji pile based on EEG spectrum features is specifically:

[0041] Step (1) Obtain the EEG data of Taiji piles.

[0042] When the nervous system is stimulated by the outside world, the action potential generated by the membrane potential can form the potential discharge. This potential emission has a certain correlation with the human body's thinking and movement, and the external manifestation is the change of the potential of the nerve group or the scalp.

[0043] The human brain is divided into four regions according to the original organization and activity type: frontal lobe, parietal lobe, occipital lobe and temporal lobe. They correspond to areas such as the frontal, parietal, occipital, and temporal bones. The EEG transformation corresponding to the attention of ordinary people is mainly controlled by the EEG cells of the prefrontal lobe, so the EEG signal of the prefrontal lobe is se...

Abstract

The invention discloses a Tai Chi pile mental state detection method based on electroencephalogram spectrum characteristics. The method comprises the following steps: firstly, acquiring Tai Chi pile electroencephalogram data, including electroencephalogram data before, in and after standing, and then carrying out median filtering and denoising; wavelet packet transformation is carried out on the electroencephalogram data, frequency bands are extracted, and then data analysis is carried out, including statistical index analysis, stage correlation test and envelope analysis; and finally, through comprehensive analysis, carrying out data verification on a corresponding data set to obtain a quantitative expression method for the treatment effect of Tai Chi pile training. The method disclosed by the invention is easy to realize on an electroencephalogram detection task, can reduce subsequent research environment errors, can analyze electroencephalogram signals measured in real time before, during and after standing, and quantitatively studies the regulation effect of Tai Chi standing on the brain and mental state of a human body.

Description

technical field [0001] The invention belongs to the field of information technology, relates to quantitatively measuring the exercise effect of a Tai Chi pile, and in particular relates to a method for detecting the mental state of a Tai Chi pile during movement based on wavelet packet transformation, envelope theory analysis, and feature z-testing. Background technique [0002] The action potential of neurons in the human brain mainly uses the opening and closing of channels related to sodium, potassium, calcium and other ions to transmit electrical signals to achieve signal transmission between neurons. In the process of brain activity, the macroscopic performance is that electrical signals of different frequencies are generated. Modern research shows that according to different bands and their corresponding brain working states, EEG signals can be classified as follows: [0003] [0004] In addition to the main frequency bands shown in the above table, σ[12~16Hz], EMG...
