Official title
Randomized Controlled Trial Evaluating Trans Auricular Vagal Nerve Stimulation in Patients With Irritable Bowel Syndrome Constipation Subtype
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study evaluates the efficacy and safety of transcutaneous auricular vagus nerve stimulation (ta-VNS) in adults with constipation-predominant irritable bowel syndrome (IBS-C). Participants will be randomized to receive either active or sham stimulation using a non-invasive auricular device over a 60-day period. The primary objectives are to assess changes in symptom severity and quality of life using validated instruments, including the IBS Symptom Severity Scale (IBS-SSS) and the IBS Quality of Life questionnaire (IBS-QOL). Secondary assessments include safety and participant compliance. This study aims to determine whether ta-VNS is an effective non-invasive therapeutic modality for improving symptoms and quality of life in patients with IBS-C.
