What this trial studies

This study investigates the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) as a non-invasive treatment for chronic constipation. Participants will be randomly assigned to either a verum group, receiving true acupoint stimulation, or a sham group, receiving stimulation at non-acupuncture points. Over a four-week period, subjects will use a TENS unit daily while tracking their bowel movements and completing weekly surveys. The study aims to assess the impact of TEAS on bowel movement frequency and quality of life for individuals suffering from functional constipation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who meet the modified ROME-IV criteria for functional constipation.

Not a fit: Patients with recurrent abdominal pain indicative of irritable bowel syndrome (IBS) or those who do not meet the criteria for functional constipation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a convenient self-care option for patients with chronic constipation, improving their quality of life.

How similar studies have performed: Previous studies have shown positive outcomes with acupuncture-based interventions for similar conditions, suggesting potential for success with this novel approach.
