Fibromyalgia is a prevalent chronic condition marked by widespread pain, fatigue, and other debilitating symptoms. This guideline provides evidence-based recommendations for nonpharmacological treatments, developed by a multidisciplinary expert group, including specialists in rheumatology, rehabilitation, pain management, traditional Chinese medicine (TCM), and evidence-based medicine. The guideline follows the RIGHT checklist and is registered with the International Practice Guideline Registry Platform. The literature review incorporates systematic reviews, meta-analyses, and randomized controlled trials (RCTs) up to March 2023, focusing on the effects of nonpharmacological interventions on pain intensity, fatigue, sleep quality, mood, and quality of life. A total of 57 studies were included, with findings supporting acupuncture and health education as core therapies. These interventions significantly reduce pain, alleviate fatigue, and improve sleep quality, and are strongly recommended based on moderate-quality evidence. Additionally, aerobic exercise and resistance training are recommended for their proven effectiveness in reducing pain, enhancing physical function, and providing long-term benefits. Emerging therapies, such as transcranial magnetic stimulation (TMS) and nutritional supplements, show promise but require further research due to low-certainty evidence.
