Effectiveness of Therapeutic Exercise in Fibromyalgia Syndrome: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Abstract EN

Objective.

The aim of this study was to summarize evidence on the effectiveness of therapeutic exercise in Fibromyalgia Syndrome.

Design.

Studies retrieved from the Cochrane Plus, PEDro, and Pubmed databases were systematically reviewed.

Randomized controlled trials and meta-analyses involving adults with fibromyalgia were included.

The primary outcomes considered in this systematic review were pain, global well-being, symptoms of depression, and health-related quality of life.

Results.

Effects were summarized using standardized mean differences with 95% confidence intervals using a random effects model.

This study provides strong evidence that physical exercise reduces pain (−1.11 [95% CI] −1.52; −0.71; overall effect p<0.001), global well-being (−0.67 [95% CI] −0.89, −0.45; p<0.001), and symptoms of depression (−0.40 [95% CI] −0.55, −0.24; p<0.001) and that it improves both components of health-related quality of life (physical: 0.77 [95% CI] 0.47; 1.08; p<0.001; mental: 0.49 [95% CI] 0.27; 0.71; p<0.001).

Conclusions.

This study concludes that aerobic and muscle strengthening exercises are the most effective way of reducing pain and improving global well-being in people with fibromyalgia and that stretching and aerobic exercises increase health-related quality of life.

In addition, combined exercise produces the biggest beneficial effect on symptoms of depression.
