Clinical Study on Dry Needling for Primary Dysmenorrhea and Its Preliminary Correlation With Acupoints

Using a single-center, randomized, single-blind study design, 150 eligible subjects were randomly divided into three groups: placebo group (pseudo-acupuncture trigger point group), TrP-DN treatment group, and traditional acupuncture treatment group. Compared with the placebo control group (trigger point sham needle group), the study evaluated the effects of TrP-DN and traditional acupuncture treatment on pain, quality of life, and long-term prognosis of PD patients. The study also observed their effects on inflammatory factors and local uterine blood flow, exploring the possible mechanisms of TrP-DN and traditional acupuncture treatment for PD. Further observations were made on the differences and similarities between conventional TrP-DN and traditional acupuncture treatment in terms of point selection, treatment effects, and their effects on inflammatory factors and local uterine circulation. The study aimed to explore the relationship between the trigger point theory and the theory of meridians and acupoints, providing a research basis for integrating TrP-DN into traditional acupuncture theory.
