This non-invasive system is activated by the cutaneous distribution of vagus nerve afferents through the external ear (auricle). Somatosensory innervation is provided by the auricular branch. The name of this device is vagustim device, which consists of a TENS device placed in the outer ear; headphones that can be selected to the size of the individual's ear and a TENS device in which stimulation current is given superficially. In our study, we will perform the application non-invasively by stimulating the branch of the vagus nerve in the auricle. The application time will take 20 minutes.

The nervus tibialis approaches the surface when it approaches the medial malleolus. In this study, transcutaneous electrical nerve stimulation (TENS) electrodes will be placed under the medial malleolus at the point where the nervus tibialis contacts the surface and approximately bilaterally.

Non-invasive transcutaneous devices stimulate the vagus nerve via the auricular or carotid artery. It is also used to treat various disorders such as epilepsy, pain and headache. This device stimulates the auricular branch of the vagus nerve non-invasively without any procedure. As a result, it has been found that the pain threshold increases and mechanical pain sensitivity decreases.

n the scale developed by Lewis and Heaton in 1990, the type of stool is classified in 7 different groups. In the Bristol Stool Scale, the transit time of stool through the intestine is evaluated over seven different stool types. According to BGS, 1-2 points are shown as "hard stool", 3-4-5 points as "normal stool" and 6-7 points as "soft-watery stool

The questionnaire for clinical assessment of the impact of pelvic pain on women consists of 10 questions. However, the first 8 questions are scored. The range of scores to be obtained from the questionnaire varies between 1- 32. As the score value to be obtained from the questionnaire increases, the degree of functional limitation of pelvic pain on the person increases.

Constipation Severity Scale (CSS): The CSS is a scale for determining the frequency, intensity and difficulty/difficulty during defecation. This scale can also be used to measure symptoms of constipation. The scale includes 16 questions.The minimum total score that can be obtained from the KCS is 0 and the maximum score is 73. A high score on the scale indicates that the symptoms are serious. The highest score that can be obtained from the five-point Likert-type scale is 140 and the lowest score is 28. As the scores obtained from the scale increase, it is thought that the quality of life is negatively affected

For the assessment, the display scale was used as visual feedback and the signal sound, which increases or decreases with changing muscle activity, was used as sensory feedback. Before starting the treatment, the desired goal for the patient is determined. 10 seconds of contraction and relaxation is practiced with the "set target" feature on the device and the average target is determined.
