To compare the effects of true and sham acupuncture in relieving symptoms of IBS. A total of 230 adult IBS patients (75% females, average age 38.4 yrs) were randomly assigned to 3 weeks of true or sham acupuncture (6 treatments) following a 3 week ‘run-in’ with sham acupuncture in an ‘augmented’ or ‘limited’ patient-practitioner interaction. A third arm of the study included a waitlist control group. The primary outcome was the IBS Global Improvement Scale (IBS-GIS) (range 1–7); secondary outcomes included IBS Symptom Severity Scale (IBS-SSS), Adequate Relief (IBS-AR) and IBS-Quality of life (IBS-QOL). Though there was no statistically significant difference between acupuncture and sham acupuncture on the IBS-GIS (41% vs. 32%, p=0.25), both groups improved significantly compared to the wait list control group (37% vs. 4%, p=0.001). Similarly, small differences that were not statistically significant favored acupuncture on the other three outcomes: IBS-AR (59% vs 57%, p=0.83), IBS-SSS (31% vs 21%, p=0.18) and IBS-QOL (17% vs 13%, p=0.56). Eliminating responders during the run-in period did not substantively change the results. Side effects were generally mild and only slightly greater in the acupuncture group. This study did not find evidence to support the superiority of acupuncture compared to sham acupuncture in the treatment of IBS.
