How much aerobic exercise is needed to reduce migraine? A dose-response meta-analysis of pain intensity and frequency
Abstract
BACKGROUND: Evidence suggests that exercise has clinically relevant benefits for migraine, but an optimal prescription standard remains undefined. We aimed to assess the effectiveness of aerobic exercise on migraine intensity and frequency through a dose-response meta-analysis.
METHODS: A data search was performed in PubMed, PEDro, Google Scholar, and EBSCO from inception to September 1, 2024. Randomized controlled trials and quasi-experimental studies of aerobic exercise in patients with a clinical diagnosis of migraine were included. The outcome measures were pain intensity and migraine frequency. The dose-response relationship was evaluated using a dose-response meta-analysis.
RESULTS: Fifteen studies (253 participants) were included. Meta-analysis showed a statistically significant decrease in pain intensity between pre and post intervention (standardized mean differences [SMD], -1.1; 95% confidence interval [CI], -1.72 to -0.47). The spline model showed a U-shape statistically significant association (χ2 = 112.03, df = 2, p < 0.001) between total minutes of aerobic exercise and reduction in pain intensity. A minimum dose of 200 min was required for moderate effects, with a maximum effect at 900 min (SMD, -2.4; 95% CI, -2.85 to -1.95). Meta-analysis showed a statistically significant decrease in migraine frequency between pre and post intervention (SMD, -0.79; 95% CI, -1.1 to -0.47). The spline model showed a U-shape statistically significant association (χ2 = 86.41, dl…
