Vagus nerve stimulation therapy (Vagal treatment ear care)

Our highly knowledgeable and skilled therapists use their hands and special vibration, heat, and rolling devices to relax the auricle and surrounding muscle groups.

The vagus nerve (English: Vagus nerve) is one of 12 pairs of cranial nerves, and is also called the Xth cranial nerve.
It is a typical parasympathetic nerve, showing a complex course and distributing to the neck, thoracic organs, and even abdominal organs.
It has the largest distribution area among the cranial nerves and is mainly composed of parasympathetic nerve fibers, but it also competes with the sympathetic nerves and controls the movement and secretion of the vocal cords, heart, gastrointestinal tract, and digestive glands. It shows an extremely complex route with many branches.
The vagus nerve originates in the lower medulla oblongata and has many branches that are widely distributed in various organs.
The motor and sensory nerves of almost all internal organs from the neck to the abdomen (the lower end of the digestive system is the right 1/3 of the transverse colon) are controlled by the vagus nerve, and its functions include regulation of heart rate, peristalsis of the gastrointestinal tract, and sweating. It is involved in speech, sensing blood gas partial pressure in the aortic body, and somatic sensation in the external auditory canal.
The fibers are mainly parasympathetic, but there are a variety of nerve nuclei involved, including the dorsal nucleus of the vagus nerve, nucleus pseudonucleus, nucleus ambiguus, nucleus fasciculus solitary, and solitary nucleus.
It also branches into the recurrent laryngeal nerve, which contains efferent fibers, within the thoracic cavity.
The recurrent laryngeal nerve inverts and ascends, innervating the muscles of the pharynx and larynx.
This shows that the vagus nerve also innervates many muscles in the mouth and plays an extremely important role in speech and opening the pharynx.
The vagus nerve innervates nearly every organ except the genitals, bladder, and descending colon.

The sensory branch provides superficial sensation from the posterior inferior wall of the external auditory canal, the posterior part of the tympanic membrane, and the small area between the bases of the auricle and mastoid, the dura mater of the posterior fossa, the esophagus, the trachea, the bronchi, and the pharynx. tell. It also transmits some of the visceral sensations from the thoracic organs and abdominal organs, andsolitary nucleusThis brings us to
The motor branch innervates the soft palate, pharynx, and most of the pharyngeal muscles, and its cell body is located in the nucleus pseudobulbar of the medullary tegmentum. Most of the efferent parasympathetic nerve branchesdorsal motor nucleus It begins in the visceral motor branch and branches into all organs other than the pelvic organs as a general visceral efferent fiber.

The vagus nerve is one of the most important control towers that connects the brain and the body, and is responsible for a huge number of functions.
Transcutaneous auricular vagus nerve stimulation (taVNS) directly targets the area where the vagus nerve is distributed in the auricle.
This is a treatment method that uses electrical stimulation.

In recent years, clinical trials have been conducted for epilepsy, depression, autism, intractable headaches, insomnia, tinnitus, functional dyspenia, post-stroke rehabilitation (upper limb function), etc., and its effects have been reported worldwide. .
When electrical stimulation is applied to the vagus nerve area of ​​the auricle, the stimulation is transmitted to the brain, and is then transmitted to various parts of the brain (midbrain, thalamus, hypothalamus, amygdala, hippocampus, prefrontal cortex, cerebellum, etc.) via the brain's neural network. has been shown to affect nerve activity and blood flow.

The autonomic nervous system is closely involved in a woman's menstrual cycle.
The autonomic nervous system has been linked to psychological symptoms such as anxiety and depression during menstruation, as well as physical symptoms such as abdominal pain and headaches, and stimulating the vagus nerve in particular may alleviate these symptoms.
The paper below from Niigata University of Health and Welfare explains the details and results of the study.
Ear care, etc. If a method to easily perform transcutaneous vagus nerve stimulation becomes widespread, it is expected that it will have revolutionary effects such as improving menstrual pain, PMS, postpartum depression, and menopausal symptoms. It can also be applied in the tech field.
Vagus nerve stimulation therapy is essential care for women's mental health.

Jesse Dawson and his colleagues at the University of Glasgow, UK, conducted a study on patients with persistent moderate to severe arm weakness after a cerebral infarction. conducted a randomized controlled trial to investigate the effects of vagus nerve stimulation, and reported that arm motor function was significantly improved when combined with vagus nerve stimulation. Result isPublished in Lancet magazine April 2021, 4 issueWas done.
Vagus nerve stimulation has great effects and is expected to be further utilized in the field of rehabilitation in the future.

Research on the effects of transcutaneous vagus nerve stimulation is introduced in the Morisawa Mental Clinic article. In the article's conclusion,
“It has been shown that transcutaneous nerve stimulation may be able to reduce the effects of insomnia, such as fatigue and decreased work ability.Currently, this nerve stimulation device is approved for headache treatment in the United States. However, it was considered to be an option as a way to promote wakefulness with few side effects.
It has been with.
[Lung activation] also activates the vagus nerve, and in addition to the alerting effect and increased work efficiency introduced in the article, it also suppresses inflammation in the body and activates the brain.
In other words, various cytokines are controlled, and it is thought that the same effects as exosome drip therapy or stem cell culture supernatant therapy can be obtained.

Since chronic pain is affected by continuous stress on the mind and body, it has been suggested that it is involved in autonomic nerve activity. Transcutaneous vagus nerve stimulation (tVNS) has attracted attention in recent years as a method for externally regulating autonomic nerve activity.
Research at Niigata University of Health and Welfare has produced results that suggest that tVNS may be used for various pain treatments.
Compared to acupuncture treatment, tVNS is sure to attract attention in the future, as it may be superior in terms of risk, ease, cost, evidence, and theory. About research at Niigata University of Health and Welfare You can read it.

Chronic cluster headaches can be difficult to treat. Can be treated with vagus nerve stimulation.

Improve neck tension Medical healing with Iacare

Vibrations and thermal stimulation of the auricle and sternocleidomastoid muscles relax the respiratory muscles and activate the vagus nerve.

The ultimate healing device for mental health

For various symptoms such as constipation, eye strain, stiff shoulders, headaches, and insomnia.

Aromatic ingredients such as essential oils have been proven to be particularly effective in regulating the autonomic nervous system, and it is expected that the effects will be further enhanced by breathing slowly and using aromas during ear care. Pulmonary Aroma has been developed based on the expert knowledge of a medical doctor, and the ingredients that are more likely to affect the autonomic nervous system are carefully selected, and can be expected to be highly effective.

It is expected to be effective in cerebral areas such as autism, treating paralysis after cerebral infarction, dementia, depression, schizophrenia, improving concentration, and possibly improving autism.
