Efficacy of acupuncture at pain-sensitive acupoints for diarrhoea-predominant irritable bowel syndrome (IBS-D): protocol of a multicentre, randomised, sham-controlled trial.

Researchers are launching a major study to test whether acupuncture can help people with diarrhea-predominant irritable bowel syndrome (IBS-D), a digestive condition that causes frequent diarrhea, abdominal pain, and discomfort. This study is important because while some research suggests acupuncture might help IBS-D patients, there haven't been enough high-quality studies to know for sure.

The trial will involve 326 patients across multiple medical centers in China. Half will receive real acupuncture at pain-sensitive points on their bodies, while the other half will receive sham (fake) acupuncture as a comparison. Neither patients nor researchers will know who receives which treatment until the study ends. Both groups will attend 15 treatment sessions over six weeks.

Researchers will measure how well acupuncture works by tracking several factors: the percentage of patients who experience meaningful relief at six weeks, overall symptom severity, quality of life, depression levels, and various digestive and non-digestive symptoms. They'll also monitor safety throughout the study.

This is a study protocol, meaning it describes what the researchers plan to do rather than reporting results. The actual findings won't be available until after the study is completed and analyzed. However, this research is significant because it uses rigorous scientific methods including a large sample size, multiple centers, and proper comparison groups—features that have been lacking in previous acupuncture studies for IBS-D.

If you're considering acupuncture for digestive issues, consult with a licensed acupuncturist certified by your state or national board.

This multicentre randomized controlled trial protocol outlines a rigorous investigation of individualized sensitized acupuncture for IBS-D management. The study will enroll 326 patients randomly allocated 1:1 to verum acupuncture at pain-sensitive points versus sham acupuncture, with 15 sessions over 6 weeks. The primary endpoint is effective response rate at week 6, with secondary outcomes including IBS-SSS, IBS-QOL, PHQ-9, adequate relief measures, and extraintestinal symptoms. This represents a methodologically robust design addressing previous gaps in the evidence base for acupuncture in IBS-D. The inclusion of pain-sensitive point selection suggests a personalized approach based on traditional acupuncture diagnostic methods. The study has received ethics approval from Beijing University of Chinese Medicine and participating institutions. As a protocol paper, no efficacy or safety data are yet available. Clinicians should await published results before modifying practice patterns, though the trial design suggests potential for generating high-quality evidence regarding acupuncture's role in IBS-D management.
