Effectiveness of aquatic training based on aerobic and strengthening exercises in patients with fibromyalgia: systematic review with meta-analysis

Abstract

Background and purpose: fibromyalgia is a chronic condition causing widespread pain, fatigue, limited physical function, and reduced quality of life. Aquatic training is recommended as a first-line non-pharmacological treatment. This study aims to evaluate the effectiveness of aquatic training based on aerobic and strengthening exercises in improving symptoms in women with fibromyalgia.

Material and methods: a systematic review with meta-analysis was conducted by searching the PubMed, Scopus, Cochrane Library and Web of Science databases. Randomized clinical trials that compared aquatic therapy with either a control group or a land-based exercise group were included. Study quality was assessed using the PEDro scale, the risk of bias was evaluated using the Cochrane Risk of Bias Tool, and the certainty of the evidence was assessed the GRADE guidelines.

Results: six randomized clinical trials comprising 9 publications showed that aquatic therapy had statistically significant benefits compared to no intervention, including pain, fatigue, fibromyalgia impact, depression, physical function, and mental health in the short term. In the medium term, improvements were observed in fibromyalgia impact, physical function, and mental health. However, aquatic therapy was not found to be superior to land-based exercise.

Conclusion: low to very low certainty of evidence suggested that aquatic training may reduce pain, fibromyalgia impact, fatigue and depression and improve physical function and mental health in patients with fibromyalgia. Further studies should investigate the medium and long-term effects of aquatic training using larger sample sizes.
