Prescription of therapeutic exercise in migraine, an evidence-based clinical practice guideline

Advances in Exercise in the Clinical Trials of Migraine: A Scoping Review

PURPOSE OF REVIEW

This review aimed to investigate emerging evidence regarding the effectiveness of exercise for migraines, focusing on the results of recent trials. Additionally, it explored the possibility of exercise as a treatment for migraines.

RECENT FINDINGS

Between 2020 and 2023, five, four, one, and two trials were conducted regarding the effect of aerobic exercise, anaerobic exercise, Tai Chi, and yoga, respectively, on migraine; all studies showed significant effects. Two trials on aerobic exercise showed that high-intensity exercise was similar to or slightly more effective than moderate-intensity exercise as a treatment for migraines. Three trials on anaerobic exercise reported its effectiveness in preventing migraines. Regarding efficacy, side effects, and health benefits, aerobic exercises and yoga are potentially beneficial strategies for the prevention of migraines. Further studies are needed to develop evidence-based exercise programs for the treatment of migraines.

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

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.

[Non-medical Approaches to Headache Prevention: What is the Evidence?]

Primary headaches can be prevented by medication, exercise, behavioral therapy, or lifestyle changes. It is important to note that if medication is used for prophylaxis, non-drug approaches should also be recommended as a complement. Patients often wish to address their headaches without medication. Except for cognitive behavioral therapy and biofeedback, the evidence for nonmedication approaches to headache management has not been definitively established. This article reviews the current literature on the evidence for endurance exercise, relaxation exercises, physical therapy, lifestyle factors, and complementary procedures. For tension-type headache, there is an increasing number of studies reporting positive results from physical therapy; long-term follow-up, however, are still pending. Aerobic endurance exercise has the best evidence as a measure for prevention of migraine. However, other methods can also be used.

Yoga for Migraine Prevention: An Ancient Practice with Evidence for Current Use

PURPOSE OF REVIEW

The objective of this study is to review the recent literature on yoga for migraine prevention either as adjuvant or standalone therapy. Yoga is one of the most widely used complementary and integrative medicine (CIM) therapies; clinicians should be familiar with yoga practice so that they can best advise interested patients. It is also important to assess study design and types of yoga offered. Using PubMed and Litmaps, research published from 2018 to 2023 addressing yoga and migraine was assessed.

RECENT FINDINGS

Two systematic reviews and six studies have recently been published on yoga as adjunctive migraine preventive treatment. There is class III evidence and a grade B recommendation for yoga as an adjunct migraine preventive treatment. Yoga has been shown to reduce headache frequency, disability, and likely also pain intensity and self-efficacy. Two studies (one in children and one in adults) suggested that yoga as standalone migraine preventive treatment reduces pain intensity, disability, and perceived stress. More research is needed on the long-term efficacy (including change in monthly migraine days specifically in addition to headache frequency) and adherence to yoga practice for the prevention of migraine. In addition, to our knowledge, there is no study evaluating yoga practice in the prodromal or headache phase of migraine as acute treatment.

Associations of Electronic Device Use and Physical Activity with Headaches in Saudi Medical Students

Background and Objectives: Primary headaches are highly prevalent among medical students, negatively impacting their health and academic performance. Excessive electronic device use has been implicated as a risk factor, in contrast to physical activity, which may be a protective factor; however, comprehensive data are lacking, especially for Saudi medical trainees. This study aims to investigate the associations between device use, exercise, and headaches among Saudi medical students. Materials and Methods: In this cross-sectional study, 504 medical students at Jazan University completed an online survey collecting sociodemographic factors, headache characteristics/triggers, electronic device habits, exercise frequency, and headache impacts. Descriptive analyses summarized sample characteristics. Logistic regression identified predictors of 12-month headache prevalence. Results: Overall, 83% reported experiencing headaches in the past year. High headache prevalence was observed among females (86.6%) and third-year students (88.3%). Using electronic devices ≥4 h daily was associated with higher adjusted odds of headaches (OR 13.89, 95% CI 1.96-98.54) compared to ≤1 h daily. Low physical activity (exercising 1 day vs. 7 days a week) also increased headache odds (OR 3.89, 95% CI 1.61-9.42). Headaches impairing productivity (OR 4.39, 95% CI 2.28-8.45) and exacerbated by exercise (OR 10.37, 95% CI 2.02-53.35) were further associated with headache susceptibility. Conclusions: Excessive electronic device use and physical inactivity appear to be modifiable risk factors for frequent headaches in Saudi medical students. Multifaceted interventions incorporating education campaigns, skills training, and support services focused on promoting responsible technology habits, and regular exercise may help mitigate headaches in this population. Robust longitudinal studies and trials are warranted to establish causal mechanisms between lifestyle factors and headaches among medical undergraduates.

The Effect of OnabotulinumtoxinA on Headache Intensity and Number of Monthly Headache Days in Individuals with Chronic Migraine with Different Levels of Neck Disability

One of the treatment methods used in chronic migraine is OnabotulinumtoxinA. The effects of OnabotulinumtoxinA on headache intensity (HI) and number of monthly headache days (NMHD) in chronic migraine (CM) patients classified according to neck disability levels are unknown. Our aim was to investigate the effect of OnabotulinumtoxinA on the HI and the NMHD in individuals with CM with different levels of neck disability. One hundred sixteen patients were enrolled in the study. The OnabotulinumtoxinA protocol was administered as per Follow-the-Pain PREEMPT. The Neck Disability Index was used to evaluate neck disability. Primary outcome measures were headache intensity, assessed with the Visual Analogue Scale, and the number of monthly headache days recorded from patients' diaries. Secondary outcome measures were migraine disability, assessed with the Migraine Disability Assessment Test, and quality-of-life, assessed with the Headache Impact Test-6. All assessments were made at baseline and end of the treatment. The OnabotulinumtoxinA treatment showed a greater improvement effect in the number of monthly headache days (p = 0.000) and migraine disability (p = 0.000) parameters in the severe and complete disability groups. CM patients with complete and severe neck disability received the most benefit in reducing the NMHD at 3 months after OnabotulinumtoxinA treatment, but the HI decreased at a similar level in all neck disability groups.
