Effects of exercise dosage on the treatment of fibromyalgia: A meta-analysis of randomised controlled trials.

Background: Exercise intensity is a key component of an exercise prescription. This meta-analysis aimed to investigate the treatment effect of different exercise doses on fibromyalgia syndrome.
Methods: PubMed, Embase, Web of Science, and the Cochrane Library were searched from their inception until 29 December 2023. The studies were subjected to screening using a 2-phase approach by 2 independent reviewers. Reference lists of the included studies were manually searched. Two independent reviewers extracted information regarding the origin, characteristics of study participants, eligibility criteria, characteristics of interventions, outcome measures, and main results using a pre-defined template.
Results: This meta-analysis encompassed a total of 19 randomized controlled trials comprising 857 patients. Compared with the low compliance/uncertain group according to ACSM, the high compliance group showed better effectiveness in general condition improvement (SMD: -1.15 > -0.71), pain relief (SMD: -1.29 > -1.04), sleep quality enhancement (SMD: -1.66 > -1.08), and fatigue relief (SMD: -1.72 > -1.32). However, there was no difference in the improvement of mental health between the two groups (SMD: -0.93 > -0.92).
Conclusion: Compared to the ACSM group with compliance uncertainty (<70%), the high compliance group showed improvement in general conditions, pain, sleep quality, and fatigue. However, there was no difference in terms of mental health.
