AbstractFibromyalgia (FM) is a complicated syndrome characterized by widespread chronic pain, fatigue, sleep disturbances, cognitive dysfunction, and other complications. There is currently no specific treatment available. No comprehensive surveys have been published to summarize the mechanism of acupuncture in FM management. Although several studies have shown that acupuncture can benefit FM patients, their clinical findings are inconsistent. Here, we summarize the operation method of acupuncture for FM. For the first time, we conducted a comprehensive review of the mechanisms of acupuncture for FM, and integrated evidence-based scientific findings with the most comprehensive and updated literature. According to studies conducted using FM patients and animal models, acupuncture may improve symptoms in FM patients by regulating the afferent pain pathway and descending inhibitory pain pathways of various molecules, such as ASIC3, Nav1.7, Nav1.8, and TRPV1, as well as peripheral inflammation and the autonomic nervous system. Furthermore, we discussed the epidemiology, pathophysiology, diagnosis, and management of FM, and reviewed acupuncture-related clinical studies. This review fills a previously unknown gap in knowledge of the mechanism of acupuncture for FM. Although there is growing evidence that acupuncture may be a promising therapy for treating symptoms in FM patients, further investigation is needed.
