Stimulation Of The Vagus Nerve Of The Ear
Stimulation of the vagus nerve of the ear is a technique applied to complex problems, such as pain management and slowing down aging. In fact, the procedure has become very popular lately. Therefore, the number of investigations to validate its effectiveness is increasing.
Studies such as those carried out by the Technische Universität Wien (Technical University of Vienna) show the effectiveness of stimulating the vagus nerve of the ear to alleviate chronic pain. The results are extremely encouraging, but more research is needed.
In this article, we will analyze the data that science can provide us so far regarding the stimulation of the vagus nerve of the ear.
Vague nerve stimulation
The ear is a gateway to the nervous system. There are specific areas where the vagus nerve is stimulated, mainly in the outer part of the ear. As this structure passes through the internal organs, the information it carries reaches most of the body.
According to Beatrice Bretherton, the study’s coordinator, vagus nerve stimulation influences the body’s metabolic balance. Fortunately, the procedure does not require medication or other invasive procedures.
You may not be aware of this, but the sympathetic branch of the vagus nerve helps the body prepare to either fight or run. The parasympathetic branch also affects rest and digestion. As people begin to age, the sympathetic branch progressively deteriorates.
The technique of stimulating the vagus nerve of the ear is used to reverse this situation. The technique activates the parasympathetic branch and brings it into balance with the sympathetic branch. The patient experiences less stress and therefore a lower risk of developing various conditions, such as those mentioned above.
Stimulation of vagus nerve fibers decreases pain. However, the biggest challenge facing doctors is placing the electrodes in the right place.
Computer models have been able to determine, with increased accuracy, which electrical signals should be used. Both the intensity and the shape of these signals are factors that influence the results.
