Study of Additive Effect of Yoga and Physical Therapies to Standard Pharmacologic Treatment in Migraine

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.

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.

Tai Chi for the prophylaxis of episodic migraine: protocol of a non-inferiority randomized controlled trial with mechanism exploration

BACKGROUND

Migraine is a complex neurovascular disorder with considerable clinical, social and economic issues. Tai chi has the potential to be an alternative prophylactic treatment for migraine with high safety since the adverse effects and limited efficacy of available medications.

AIMS

The proposed study aims to compare the prophylaxis efficacy of 24-week Tai Chi training on migraine attacks with the standard prophylactic medication; and to explore the mechanism of Tai Chi in preventing migraine attacks by analyzing the associations between changes of migraine attacks and changes of neurovascular functions and inflammatory makers.

METHOD

This is a two-arm parallel non-inferiority randomized controlled trial. In total 220 Hong Kong Chinese women aged 18-65 years with diagnosis of episodic migraine will be recruited and randomized to either the Tai Chi training group or the standard prophylactic medication group with 1:1 ratio, and receive the 24 weeks of modified 33-short form Yang-style Tai Chi training and the standard prophylactic medications, respectively. A 24-week follow-up will be implemented for both groups. For efficacy examination, the primary outcome was the frequency of migraine attacks measured by the migraine diary; and for the mechanism exploration, the primary outcome was the volume and number of white matter hyperintensity (WMH) measured by magnetic resonance imaging (MRI). The measurements will be conducted at the baseline, 24th weeks, and 48th weeks. Linear mixed model will be adopted to comprehensively analyze the changes of variables within and between groups.

DISCUSSION

Given the importance of reducing disease burden and financial cost of migraine attacks, the findings of this study will provide new insights regarding the role of Tai Chi in alleviating migraine burden and further shed light on the mechanism action of Tai Chi on preventing headache attacks.

Effect of Pranayama as Adjuvant to Medical Treatment on Severity, Frequency, and Duration of Headache in Migraine Patients: An Open-Label Randomized Controlled Trial

Background

Migraine is the second leading cause of disability worldwide with high rates of dissatisfaction for allopathic treatment among patients. Pranayama is an easy, convenient, and cost-effective method that can supplement existing standard medical treatment of migraine.

Objective

To study the effect of pranayama as an adjuvant to standard medical treatment of migraine on clinical outcome variables of migraine.

Materials and Methods

This was a randomized controlled trial conducted on 80 consecutive migraine patients who were diagnosed as per International Classification of Headache Disorders-3 (ICHD-3) criteria and were randomly allocated into two groups, that is, standard medical treatment (SMT) group and standard medical treatment plus pranayama (SMT + P) group. The effect of pranayama on clinical outcome variables of migraine was evaluated by using standardized questionnaires. The data was statistically analyzed using SPSS Statistics 20 software. A P value of ≤0.05 was considered statistically significant.

Results

Intragroup analysis showed all clinical outcome variables of migraine reduced significantly in the SMT + P group whereas all clinical outcome variables of migraine except the duration of headache episodes reduced significantly in the SMT group. Although statistically non-significant, intergroup analysis demonstrates that reduction in headache severity, duration of headache episodes, and headache impact test-6 (HIT-6) score was more in the SMT + P group whereas reduction in headache frequency and migraine disability assessment (MIDAS) score was more in the SMT group.

Conclusion

Pranayama supplements the standard medical treatment of migraine by reducing the duration of headache episodes in addition to the reduction in headache severity, headache frequency, HIT-6 scores, and MIDAS scores.

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

The main objective of this clinical practice guideline is to provide a series of recommendations for healthcare and exercise professionals, such as neurologists, physical therapists, and exercise physiologists, regarding exercise prescription for patients with migraine.This guideline was developed following the methodology and procedures recommended in the Appraisal of Guidelines for Research and Evaluation (AGREE). The quality of evidence and strength of recommendations were evaluated with the Scottish Intercollegiate Guidelines Network (SIGN). A systematic literature review was performed and an established appraisal process was employed to rate the quality of relevant scientific research (Grading of Recommendations Assessment, Development, and Evaluation methodology).The evaluation of the current evidence, the elaboration of the grades of recommendation, and their validation show a B grade of recommendation for aerobic exercise, moderate-continuous aerobic exercise, yoga, and exercise and lifestyle recommendations for the improvement of symptoms, disability, and quality of life in patients with migraine. Relaxation techniques, high-intensity interval training, low-intensity continuous aerobic exercise, exercise and relaxation techniques, Tai Chi, and resistance exercise obtained a C grade of recommendation for the improvement of migraine symptoms and disability.

Exercise interventions in migraine patients: a YouTube content analysis study based on grades of recommendation

Background

Migraine is the second leading cause of disability worldwide, engendering a high economic cost in developed countries. The adverse events related to pharmacological treatment use have increased interest in non-pharmacological interventions such as exercise. YouTube offers a public source of information for migraine patients regarding exercise interventions for migraine improvement. However, this information has not been validated to ensure the quality and validity of its content.

Objective

This qualitative content analysis study aims to review and evaluate YouTube videos regarding exercise for migraine.

Methods

A systematic review of the current evidence regarding exercise for migraine was performed to establish evidence classification and grades of recommendation with the Scottish Intercollegiate Guidelines Network tool. The data sources were PubMed, PEDro, Cochrane, EBSCO, Google Scholar and Web of Science. The quality of YouTube videos on exercise in migraine was reviewed using the Global Quality Scale and DISCERN scale. Finally, the classification in grades of recommendation was used to evaluate the included videos in terms of the various exercise modalities.

Results

The classification into recommendation grades showed a grade B for aerobic exercise, yoga and changes in lifestyle behavior regarding exercise. A total of 129 videos were included. The healthcare and exercise professional authors produced higher quality videos with a significant statistical difference, although the alternative therapists and patients' videos had a greater impact and a higher viewership based on correlation analysis. The evaluation of the videos based on the recommendation grades could only include 90 videos. 71% of these videos showed a B grade of recommendation, which corresponded to fewer than half of the total included videos.

Conclusions

YouTube needs higher quality videos on exercise for migraine, and healthcare and exercise professional authors need to improve their scoping strategies to acquire more views. The authors of YouTube videos should have better access to the best current evidence regarding exercise interventions in migraine.

Integrative, Interventional, and Non-invasive Approaches for the Treatment for Migraine During Pregnancy

PURPOSE OF REVIEW

While most women with migraine improve during pregnancy, a subset may remain unchanged or even become more severe. Given the limited evidence for the use of prescription medications during pregnancy, many look to other treatment modalities. We seek to review complementary and integrative medicine, procedural interventions, and neurostimulation to empower women with safe and effective treatment options during pregnancy.

RECENT FINDINGS

Migraine treatment during pregnancy remains controversial. While evidence is limited, prospective and retrospective reviews, as well as clinical experience support the use of nutraceuticals, procedural interventions, and neurostimulation during pregnancy when the appropriate risks and benefits are weighed. Empowering patients with information on complementary and integrative medicine, as well as non-systemic and interventional treatments, may help to reduce anxiety and headache burden during pregnancy. Various nutraceuticals have shown promise for the preventive management of migraine. Non-systemic interventions such as trigger point injections and peripheral and sphenopalatine nerve blocks offer effective treatment options with minimal side-effects. Options for neurostimulation have expanded in recent years and may offer safe and effective non-pharmacologic options for the management of migraine. It is imperative that providers do not minimize migraine during pregnancy and become aware of the treatment modalities available to help guide women through this experience.

Effectiveness of yoga therapy for migraine: A meta-analysis of randomized controlled studies

INTRODUCTION

The efficacy of yoga therapy for migraine remains controversial. We conduct this meta-analysis to explore the influence of yoga therapy on the treatment efficacy of migraine.

METHODS

We have searched PubMed, EMbase, Web of science, EBSCO and Cochrane library databases through February 2021, and included randomized controlled trials (RCTs) assessing the efficacy of yoga therapy for migraine attack.

RESULTS

Five RCTs involving 356 patients were included in the meta-analysis. Overall, compared with control group for migraine, yoga therapy was associated with substantially reduced headache frequency headache frequency (SMD = -1.43; 95% CI = -2.23 to -0.64; P = 0.0004) and HIT-6 score (SMD = -2.19; 95% CI = -4.09 to -0.28; P = 0.02), but revealed no obvious influence on pain intensity (SMD = -1.37; 95% CI = -2.76 to 0.01; P = 0.05) or McGill Pain Questionnaire (SMD = -2.09; 95% CI = -6.39 to 2.22; P = 0.34).

CONCLUSIONS

Yoga therapy may benefit to reduce the headache frequency of migraine patients.

[Effectiveness of physiotherapeutic treatment interventions on pain intensity, duration, frequency, and quality of life of patients with migraine : A systematic review]

BACKGROUND

According to the current guidelines preventive treatment of migraine should consist of a combination of pharmacological and nonpharmacological forms of treatment. Physiotherapeutic modalities could be an option for nonpharmacological migraine management.

OBJECTIVE

The aim was to assess the efficacy of physiotherapeutic interventions on pain intensity, duration and frequency as well as the quality of life of patients with migraine.

METHODS

A systematic literature search was carried out in four databases: the Physiotherapy Evidence Database (PEDro), Web of Science, Medline via PubMed and the Cochrane Library. Randomized controlled trials (RCTs) that were published up to the end of July 2021 and examined the effectiveness of physiotherapeutic treatment in migraine patients were eligible for inclusion. Studies that did not examine an adult population, interventions not carried out by a physiotherapist or not reporting an appropriate outcome were excluded. The assessment of the risk of bias was carried out with the revised version of the Cochrane risk of bias tool 2.0. A descriptive and quantitative synthesis using mean difference with a random effects model and 95% confidence intervals were used.

RESULTS

The present review included 13 RCTs reporting on a total of 595 patients. The risk of bias was high for four studies, low for two studies and the remaining seven studies had some concerns. The interventions examined were multimodal physiotherapy programs, various mobilization techniques, trigger point therapy, manual lymphatic drainage, massage and various stretching techniques. All interventions examined had a significantly positive effect on the selected parameters compared to the baseline values. Especially combinations of various physiotherapeutic modalities showed clinically relevant results.

CONCLUSION

The evidence suggests that multimodal physiotherapy treatment is a good supplement to medication and should therefore be considered as a nonpharmacological treatment for patients with migraine; however, further RCTs with a low risk of bias are necessary in order to confirm the effectiveness with high quality evidence.
