Transcranial stimulation-based mental state assessment and regulation system and working method thereof

Abstract

The invention provides a mental state assessment and regulation system based on transcranial stimulation. The mental state assessment and regulation system is characterized by comprising the followingparts: a physiological signal acquisition module for acquiring a physiological signal of a tested subject; a mental state assessment module used for performing physiological signal preprocessing, feature extraction and mental state analysis to obtain a mental state assessment result; control equipment used for judging the mental state evaluation result and adjusting stimulation parameters according to the mental state evaluation result; and transcranial stimulation equipment used for performing transcranial stimulation on the tested subject according to the stimulation parameters. The mentalstate assessment and regulation system can carry out personalized targeted mental state regulation on the tested subject, has a good mental state adjustment effect, is convenient and effective to use,and has the advantages of noninvasiveness, effectiveness, safety, easiness in operation and the like. The invention further provides a working method of the mental state assessment and regulation system.

Description

technical field [0001] The invention relates to the technical field of mental state assessment and regulation, and more specifically, relates to a mental state assessment and regulation system based on transcranial stimulation and a working method thereof. Background technique [0002] Most of the existing mental state regulation methods are self-regulation, such as listening to soothing music to regulate anxiety, watching some funny videos to regulate depression, etc. However, for sub-healthy people suffering from severe anxiety, depression and other mental states, self-regulation often cannot play a good role, and external forces are needed to adjust the mental state, such as psychotherapy and drug relief. [0003] In order to effectively regulate the mental state, electrical stimulation methods are currently used, including transcranial magnetic stimulation (TMS), transcranial electrical stimulation (TES), and transcranial ultrasound stimulation (TUS), which do have biolo...

Problems solved by technology

[0004] However, the existing electrical stimulation treatment or adjustment method is only a simple low-frequency pulse electrical stimulation, and the subjects are in a passive treatment or adjustment mode. Since there is no detection feedback after the subjects receive the electrical stimulation, the treatment method is single, and the treatment process has no effect. Data reference; and most of the existing stimulation systems select relevant stimulation parameters based on the experience of professionals, such as stimulation intensity, stimulation frequency, and stimulation time, and cannot quantify the stimulation effect, and dynamically adjust according to the quantitative results

Because different people have different tolerances to transcranial stimulation, it is difficult to accurately judge the tolerance of the human body and adjust the stimulation parameters by manually selecting stimulation parameters based on experience.

In summary, empirical parameter settings and traditional stimulation modes are difficult to meet individualized treatment needs, which can easily lead to excessive stimulation or insufficient stimulation, and cannot achieve effective or optimal mental state regulation effects.
