The god Apollo in ancient Greek mythology was in charge of ** and medical treatment, and the ancient Chinese character "樂" (乐) derived the word "medicine" (medicine), indicating that human beings have long recognized the relationship between "** and medicine". With the development of human social civilization, the role and function of the virus have been gradually recognized and formed into a variety of forms, and the vibroacoustic therapy (VAT) is one of them. In recent years, the effect has been very significant, but the somatosensory in the first is still relatively unfamiliar, the author mainly discusses VAT and its application.

1.1 Definition of VAT **Different from what is said in daily life**, it has the most basic three elements, namely**, object, **teacher. The three are indispensable, influence each other, promote each other, improve mood with **, indirectly ** disease, and promote the recovery of patients' health.

VAT stands for somatosensory vibration***, also known as vibroacoustics**, which is a technology that uses the "bone conduction mode" and psychological and physiological dual stimulation to act on the patient's body and mind by amplifying and physically transducing the low-frequency signal of 16 150 Hz through the method of "body perception" [1]. VAT belongs to the category of receptive type, which not only experiences the melody in hearing, but also integrates the inherent physiological vibration frequency of breathing, heart rate, blood pressure and other vibration frequencies in the human body with the vibration frequency, so that the patient can feel the change of the vibration frequency in the body's tactile sense. **Combined with somatosensory, the two complement each other, listen to the wonderful ** while experiencing the body, so that the human body can obtain high-quality pleasure and relaxation in a short time, which can effectively alleviate depression, anxiety, insomnia, neurological disorders and other psychosomatic diseases, and meet the pursuit of psychological comfort of contemporary people.

1.2 The development of VAT VAT was formed in the 80s of the 20th century, founded by Professor Shearer of Norway on the basis of clinical trial research, and was perfected under the continuous exploration of Dr. Komatsu Akira in Japan. Professor Shearer, a Norwegian educator and a family working with children, found that placing a child with cerebral palsy with muscle spasms on a large horizontal speaker can make the child feel happy and relieve muscle spasm, and the child's body can improve the symptoms of his disease by feeling the frequency of sound wave vibrations, so he designed a simple somatosensory bed [2]. On the basis of Professor Shearer's research, researchers have successively designed different types of somatosensory audio equipment, such as somatosensory beds and somatosensory chairs, especially in Europe and Japan. This technique is also used in different fields, such as neurosis after stroke, muscle spasm, head injury, perioperative anxiety, autism, severe learning disabilities, dysmenorrhea, chronic pain and other psychosomatic diseases

Wei Yulin's team from China-Japan Friendship Hospital created the first representative professional somatosensory vibration relaxation room in China, and established a Chinese somatosensory vibration research collaboration group from 2002 to 2006 to create a somatosensory relaxation with Chinese national style. Domestic scholars are more inclined to combine traditional Chinese medicine with somatosensory, and traditional Chinese medicine believes that the palace sound is melodious and harmonious, helps the spleen and health, and strengthens appetite; Shang Yin is sonorous and solemn, good at controlling anger and making people peaceful; The horn tone is comfortable and peaceful, good at dissipating melancholy; Helping people sleep; The sound is suppressed and raised, the blood is regulated, and the spirit is violated; The feather sound is soft and thorough, inspiring and enlightening. When the ** vibration coincides with the physiological vibration of the human body, it will resonate and resonate. In listening, let the tune, emotion, and heart resonate and interact, which can cleanse the blood and penetrate the soul. Qu Fei et al. [3] studied the effect of acupuncture combined with somatosensory** on upper limb spasticity after stroke, and the results showed that this method could effectively improve the upper limb spasticity and improve the motor function and daily living activities of patients. Li Yuhua et al. [4] applied Wuxing VAT to 55 patients with post-stroke depression, and their depression scores were reduced. This has been shown to promote improvement in depressive state after stroke. With the continuous development of ** and assistive ** technology, the use of single-stringed instruments and vibroacoustic equipment has also received extensive attention in the use of ** to guide relaxation and imagination technology [5].

1.3 Principles of VAT

1.3.1 Appropriate frequency range In physics, the frequencies that the human ear can accept are between 20 and 2 000 Hz. VAT uses frequencies in the human hearing range, with lower frequencies (100 Hz) being the best, which is more helpful for relaxation and pain and symptom relief. The natural frequency of tissue cells is less than 15 Hz, which belongs to the frequency range of infrasound, which can cause cell resonance. It has been shown that the use of 20 Hz somatosensory vibration stimulation is feasible to modulate brain function [6]. The VAT used by Dr. OL** Sskille in Norway is 16 160 Hz. In the microcirculation mechanism of the meridians, the frequency that causes the resonance of the twelve meridians does not exceed 110 Hz [7]. Bergstr M-Isacsson et al. [8] applied somatosensory tones in the range of 20 to 70 Hz in the neurophysiological response of **somatosensory response to Rett syndrome). The appropriate frequency is not a fixed value, but a range. The scope is flexible and variable depending on the patient's individual experience, and is not set in stone and cannot be generalized. This individual difference also makes it difficult and difficult to carry out VAT [9].

1.3.2 Neuromodulation Mechanism The use of sound vibrations to form tactile stimuli while listening to ** is the main feature of somatosensory**. The VAT combines mental processes (listening**) with physiological processes (sound, vibration, touch) to activate both efferent and afferent neural activity that inhibits pain, and integrates the organism and auditory nerve activity to support the synergistic mechanisms of the central nervous system [10]. Listening can make people feel happy and relaxing, because it can trigger an emotional response. **The emotional responses evoked are controlled and regulated by the limbic system, thalamus, and emotional behavior-related brain regions (insula, cingulate cortex, hypothalamus, hippocampus, amygdala, and prefrontal cortex) [11]. These brain regions and pathways are also related to mobility and reward mechanisms, which are conducive to the formation of the highest pleasure and in clinical practice are conducive to improving patient compliance.

1.3.3 Pacinian corpuscle (PC) inhibits neuronal pain The human body is able to distinguish between different tactile stimuli and is regulated by mechanoreceptors in the receptor sensory system. Mechanoreceptors are sensory neurons that receive various mechanical stimuli and transmit signals through the spinal cord to the sensory cortex of the brain [12]. PC, also known as Panshenny bodies, are mechanoreceptors located around internal organs and joints, mainly distributed in subcutaneous connective tissues, and can sense vibration and pressure stimuli at 20 1 000 Hz [13]. Trials and clinical studies have shown that vibration reduces the amount of pain experienced by the body [14-15]. When somatosensory** acts on the body, the receptor PC receives vibrational pressure and stimulation, and sends inhibitory pain signals to the brain through nerve transmission to reduce the pain response. Studies have shown that among the mechanosensory channels, the Pacinian channel plays a prominent and decisive role in regulating pain, and has had a significant effect on the hand [16].

1.3.4 Vibration Cleaning Mechanism It is known that the peripheral lymphatic circulation helps in the transport and cleaning of intracellular substances, but the brain lacks a lymphatic system and can only rely on the capillary wall to form a blood-brain barrier with glial cells, which is a special mechanism for brain cell cleaning. Vibrations perceived by the body (eg, VAT) and those caused by vocalizations (eg, talking, shouting, singing, humming) are transmitted to the brain through bone conduction and amplified in the interluminal and membrane structures, helping macromolecules and toxins to diffuse from the brain [17]. This suggests that somatosensory vibrations contribute to the self-purification of brain cells, but this principle is only a possibility and needs to be further demonstrated.

2.1 Pain Relief Pain management has received a high degree of attention in recent years, and pain has been ranked as the fifth most important vital sign. Severe pain that is clinically unbearable mostly requires medication control, but for mild chronic pain, physical pain has shown some advantages. As mentioned earlier, VAT has achieved significant results in pain relief. Bieligmeyer et al. [18] applied somatosensory** to cancer patients, which significantly reduced pain and greatly improved their sense of well-being. Shepovalnikov et al. [19] combined somatosensory ** with electroacupuncture** fibromyalgia, and the results showed that the impact of fibromyalgia in the ** group was significantly reduced in the score of the health assessment questionnaire. It has been shown that the combination of ** and vibration can significantly improve fibromyalgia symptoms. In a study on pain relief caused by knee osteoarthritis, 15 patients who received VAT found that the patients had less pain and improved quality of life. It has been shown that the addition of whole-body vibration training can lead to better outcomes in patients with knee osteoarthritis [20].

VAT has applications in many pain neighborhoods, especially for various chronic pains, such as low-frequency vibration to exercise muscles, relieve joint pain, accelerate postoperativeity**, and alleviate psychogenic pain caused by psychosocial factors. Although somatosensory** pain relief can be used in a wide range of applications, it is important to note that VAT should not be used in acute pain and inflammation, as this can aggravate the degree of pain or inflammation.

2.2 Alleviate anxiety VAT is mainly to promote patients to enter a relaxed state or called relaxation response, this relaxation response includes body, emotional, mental relaxation, with breathing, heart rate, blood pressure and metabolism slowing down as the main characteristics. When the body develops a relaxation response, anxiety caused by different causes is relieved. When VAT is used as a palliative treatment** for dying patients, it can relieve the anxiety and fear of death [21], so that they can die quietly in a quiet and relaxed state, which belongs to the category of hospice care. Hu Lingjuan [22] applied VAT to ** surgical patients to observe its effect on preoperative anxiety, and the results showed that VAT can effectively alleviate anxiety, reduce blood pressure, and slow down heart rate in elective surgery patients, and can be applied to routine surgical intervention.

somatosensory can also be used for anxiety disorders in psychiatric disorders. Anxiety disorders are mood disorders characterized by persistent nervousness, worry, fear, or episodic panic, accompanied by behavioral features such as autonomic nervous system symptoms and motor restlessness [23]. Liang Jiawen [24] used traditional Chinese medicine to distinguish the syndrome of ** combined with VAT** anxiety disorder, and the anxiety self-rating scale in the ** group was significantly reduced. It shows that VAT is a stable and long-lasting treatment for anxiety disorders. The application of VAT to outpatient clinics and families** is beneficial to alleviate the symptoms of anxiety disorders and reduce their psychological burden.

Some somatosensory*** systems come with their own conditioning training, including breathing relaxation and muscle relaxation. Relaxation and regulation before VAT makes it easier to integrate into the environment, promote relaxation responses, and reduce anxiety.

2.3 Stress regulation The autonomic nervous system is able to adjust the body's intrinsic functions and achieve optimal state to maintain the original or rebuild and adapt to the new homeostasis; Antagonism of the parasympathetic and sympathetic nervous systems is key to ensuring adaptive adjustment at the physiological level [25]. The persistence of stress can cause autonomic nervous system dysfunction, and VAT regulates the stress response by adjusting autonomic nervous system function. A study in Germany on the effect of somatosensory ** on heart rate variability showed that ** was effective in relieving stress by altering the autonomic nervous system [26].

In response to physiological stress, the body produces cortisol through the hypothalamic-pituitary-adrenal axis to relieve stress. VAT regulates cortisol levels, which reduces mental stress. Studies of the effects of monochord somatosensory in patients with psychosophilia have shown that monochord somatosensory affects salivary cortisol levels and indirectly regulates stress [27]. The level of cortisol in the body is affected by many factors, and there is no unified conclusion on the quantitative change of cortisol by single string**, which needs to be continuously explored.

2.4 **Depression Depression is a common mental illness that has a serious impact on human physical and mental health, and belongs to the category of mood disorders, mainly manifested by depressed mood, slow thinking, decreased volitional activity, etc., and in severe cases, cognitive impairment [28]. Relieving depression and relaxing the mood is essential for people with depression. Liu Xiaochen et al. [29] studied the post-stroke depression of VAT combined with acupuncture**, and showed that somatosensory** combined with acupuncture could alleviate depression, promote neurological recovery, and improve quality of life. Yue Hongxia [30] found that acupuncture combined with VAT can effectively improve the depression of depressed patients after stroke, improve the quality of life of patients, and promote the process of depression patients after stroke. Psychiatric illness is complex, the efficacy of medication alone is longer, and somatosensory is essential as an adjunct to the patient's early development. At present, somatosensory ** is mostly used for patients with post-stroke depression**, but it is rarely used for depressive episodes without comorbidities, especially in adolescents, which needs to be further studied.

2.5 Improve sleep Sleep is an indispensable physiological process for maintaining the health of the body. About 300 million adults in China suffer from sleep disorders such as insomnia or excessive sleepiness, which seriously affect their physical and mental health and quality of life. Zhu Lijuan et al. [31] applied VAT to 30 patients with sleep disorders, and the patients' sleep quality, sleep efficiency and daytime function were improved, and the study showed that on the basis of drugs, adding VAT can better improve the sleep status of patients with sleep disorders, soothe emotions, and promote physical and mental health. Shi Yuhang et al. [32] showed that VAT can improve sleep conditions while adjusting the physical and mental state of patients, which is beneficial to sleeplessness**.

The nourishment of life is balance.

The laboratory of Materia Medica screens basic elements such as rhythm and melody through experts and artificial intelligence, reveals the neural coding mechanism of these elements at the scale of synapses, cells, and neural pathways, and studies the impact of brain plasticity in physiological processes such as early life and individual growth and development, and studies the correspondence and mechanism of different types of brain dynamic functional connections based on the principles of brain science and artificial intelligence, and explores the symptoms of sleep disorders, anxiety and depression Intervention protocols.

With the value proposition of "living lightly and slowly", through the unique three-dimensional perspective of intelligent science, health philosophy and life aesthetics, we provide a foundation for contemporary people in their daily lives"body"、"Heart"、"Spirit"Three major health needs, carefully created a set of comprehensive and meticulous solutions. This program delicately nourishes our body and mind like spring rain, and injects a steady stream of vitality and brilliance into our lives.

3 Summary.

As a non-invasive physical** method, VAT is used to prevent pressure ulcers, promote circulation, release body and mind after surgery** and in sub-health states through a variety of mechanisms to relieve pain, promote relaxation responses, relieve anxiety and depression, and reduce stress. VAT needs to be attended by a teacher, the environment should be spacious and quiet and in line with the atmosphere of enjoyment, the volume should be appropriate, the process should include guidance before the end, stage, reminder before the end, and be accompanied by professionals throughout the process to ensure the safety of patients, but should not interfere with patients. The latest somatosensory** equipment can also connect somatosensory beds or somatosensory chairs in parallel for group somatosensory***

4 Lookouts.

The literature shows that about 300 million people worldwide suffer from depression,2More than 600 million people suffer from anxiety disorders, of which 5.4 million are registered with severe mental illness in China, with a prevalence rate of 175% [33], which seriously affects daily life and work. Some patients with anxiety disorders and depression will show obvious somatization symptoms, and it is worth researchers to use somatosensory ** to psychologically relieve emotions, reduce stress, relieve anxiety, and reduce patients' pain physically. Psychiatric training is an important measure of mental illness, and adding somatosensory training to training can enrich the training content of patients. In addition to drugs, the methods of psychiatric disorders include painting, art and other physical diseases, and studies on the effect of group painting on adolescent depression have shown that painting can improve the self-esteem and cognitive function of adolescent depression [34]. Painting belongs to the same category of art, and it is particularly important to apply VAT to psychiatric disorders as physics.

There are many forms, and there is no standardized process for somatosensory**, so the efficacy of VAT cannot be quantitatively evaluated, and the difference with *** cannot be accurately compared. The process of forming VAT and the difference between its efficacy and that of general VAT are the focus of the author's future research.
