Analgesic Efficacy of Acupuncture on Chronic Pelvic Pain: A Systemic Review and Meta-Analysis Study

Chronic pelvic pain (CPP) is the pain occurred in the pelvic region longer than six months. The monotherapy of medicine may not adequate for the pain management of CPP and multidisciplinary approaches have been more recommended. The aim of this study is to evaluate the pain management efficacy of acupuncture compared with a control group on CPP. The articles of randomized controlled trial on CPP in PubMed and Embase databases were screened between January 2011 and September 2022 without language restriction to evaluate the treatment efficacy of acupuncture. The visual analogue scale/numerical rating scale (VAS/NRS) and total pain scores of National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) were served as outcome variables. Post-intervention mean scores were extracted and pooled for meta-analysis. Seventeen studies including 1455 patients were selected for meta-analysis. Both total pain scores of NIH-CPSI and VAS/NAS data revealed significant lower pain level in the acupuncture group than in the control group. Moreover, monotherapy with acupuncture revealed a significantly lower pain level than in the control group in both total pain scores of NIH-CPSI and VAS/NRS. These results indicated that acupuncture may have beneficial effects on pain management for CPP, even when administrated as a monotherapy.
