Efficacy of Different Nerve Stimulation Methods in Individuals With Chronic Constipation

April 27, 2023 updated by: hazal genc, Istanbul Medipol University Hospital
Constipation is the most common digestive complaint in the general population. Normal stool frequency ranges from at least three times a week to a maximum of two times a day. Constipation can be classified into three main groups as constipation with normal transit time, constipation with slow transit time and dyssynergic defecation disorders.

Detailed Description

In chronic constipation, treatment should be directed towards the underlying cause. In the treatment of chronic constipation, lifestyle changes and physiotherapy are in the first place, pharmacological treatment is in the second place, and surgical treatment is in the third place. Physiotherapy modalities such as defecation training, classical massage, electrical stimulation, anorectal biofeedback and exercise training can be used in the treatment of chronic constipation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Auricular vagus stimulation
Non-invasive transcutaneous devices stimulate the vagus nerve via the auricular route or from the carotid.
Device: Auricular vagus stimulation
When the nervus tibialis approaches the medial malleolus, it approaches the surface. In this study, bilateral transcutaneous electrical nerve stimulation (TENS) electrodes will be placed under the medial malleolus approximately at the point where the tibialis nerve contacts the surface.
Experimental: Tibial Nerve Stimulation
Transcutaneous tibial nerve stimulation (TTNS) is reported to be beneficial for fecal and urinary incontinence. A review of the literature showed that there are very few studies using TTNS that have been shown to be effective for constipation.
Device: Tibial Nerve Stimulation
When the nervus tibialis approaches the medial malleolus, it approaches the surface. In this study, bilateral transcutaneous electrical nerve stimulation (TENS) electrodes will be placed under the medial malleolus approximately at the point where the tibialis nerve contacts the surface.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Bristol Stool Scale
Time Frame: 4 weeks
Bristol Stool Scale (BGS) In the scale, the type of stool is classified into 7 different groups. In the Bristol stool scale, the intestinal transit time of stool is evaluated over seven different stool types. According to BGS, 1-2 points are "hard stools", 3-4-5 points are "normal stools" and 6-7 points are "soft-watery stools (diarrhea)".
4 weeks
Pelvic Pain Impact Questionnaire
Time Frame: 4 weeks
The clinical assessment of the effect of pelvic pain on women consists of 10 questions. However, the first 8 questions are scored. The range of points to be taken from the questionnaire varies between 1 and 32. As the score to be obtained from the questionnaire increases, the degree of functional limitation of pelvic pain on the person also increases.
4 weeks
Superficial Electromyography Biofeedback
Time Frame: 4 weeks
Before starting the treatment, the target that the patient wants to reach is determined. With the "set target" feature on the device, tensing and relaxation are practiced for 10 seconds and the average target is determined. Then, the target is created by taking the percentage of this determined target. Since the goal in this study is relaxation, the patient is asked to decrease the value on the graph during the session.
4 weeks
Constipation Severity Scale
Time Frame: 4 weeks
The lowest possible total score is 0, and the highest is 73. A high score from 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. It is thought that as the scores obtained from the scale increase, the quality of life is negatively affected.
4 weeks
Autonomic nervous system device
Time Frame: 4 weeks
In the study, the autonomic nervous system will be evaluated with the Polar H10 device. By connecting the device to a smart phone via bluetooth, the data will be recorded and the software supported by the device will be used for the analysis of the data. A measurement will be made with the participant in a sitting position and lasting up to 3 minutes.
