Efficacy of various exercise interventions for migraine treatment: A systematic review and network meta‐analysis

Abstract Objective To compare various exercise modalities’ efficacy on migraine frequency, intensity, duration, and disability. Background Exercise has been shown to be an effective intervention to reduce migraine symptoms and disability; however, no clear evidence exists regarding the most effective exercise modalities for migraine treatment. Methods A systematic review was performed in PubMed, PEDro, Web of Science, and Google Scholar. Clinical trials that analyzed the efficacy of various exercise modalities in addressing the frequency, intensity, duration, and disability of patients with migraine were included. Eight network meta‐analyses based on frequentist (F) and Bayesian (B) models were developed to estimate the direct and indirect evidence of various exercise modalities. Standardized mean difference (SMD) and 95% confidence (CI) and credible intervals (CrI) were calculated for each treatment effect based on Hedge's g and p scores to rank the modalities. Results We included 28 studies with 1501 migraine participants. Yoga (F: SMD −1.30; 95% CI −2.09, −0.51; B: SMD −1.33; 95% CrI −2.21, −0.45), high‐intensity aerobic exercise (F: SMD −1.30; 95% CI −2.21, −0.39; B: SMD −1.17; 95% CrI −2.20, −0.20) and moderate‐intensity continuous aerobic exercise (F: SMD −1.01; 95% CI −1.63, −0.39; B: SMD −1.06; 95% CrI −1.74, −0.38) were significantly superior to pharmacological treatment alone for decreasing migraine frequency based on both models. Only yoga (F: SMD −1.40; 95% CI −2.41, −0.39; B: SMD −1.41; 95% CrI −2.54, −0.27) was significantly superior to pharmacological treatment alone for reducing migraine intensity. For diminishing migraine duration, high‐intensity aerobic exercise (F: SMD −1.64; 95% CI −2.43, −0.85; B: SMD −1.56; 95% CrI −2.59, −0.63) and moderate‐intensity continuous aerobic exercise (SMD −0.96; 95% CI −1.50, −0.41; B: SMD −1.00; 95% CrI −1.71, −0.31) were superior to pharmacological treatment alone. Conclusion Very low‐quality evidence showed that yoga, high‐ and moderate‐intensity aerobic exercises were the best interventions for reducing migraine frequency and intensity; high‐ and moderate‐intensity aerobic exercises were best for decreasing migraine duration; and moderate‐intensity aerobic exercise was best for diminishing disability.
