Effectiveness of Exercise and Manual Therapy as Treatment for Patients with Migraine, Tension-Type Headache or Cervicogenic Headache: An Umbrella and Mapping Review with Meta-Meta-Analysis

[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.

Effectiveness of Nonpharmacological Measures on Improving Headache Score, Strength, Pain, and Quality of Life in Cervicogenic Headaches: A Systematic Review

Cervicogenic headache (CGH) is a common condition affecting a significant portion of the population and is effectively managed through various interventions, including nonpharmacological approaches. Physical therapy plays a crucial role in CGH management, with numerous studies supporting its effectiveness. This systematic review aimed to evaluate the effectiveness of specific nonpharmacological physical therapy interventions for CGH. A comprehensive search was conducted across various databases (PubMed, Medline, PEDro, and Cochrane Library) for randomized controlled trials (RCTs) published between January 2017 and January 2023 investigating the effectiveness of specific nonpharmacological physical therapy interventions for CGH. We employed manual searches to capture potentially missed studies. Independent reviewers screened all studies based on predefined eligibility criteria. Extracted data included methodology, specific interventions, outcome measures (headache score, strength, pain, and quality of life (QOL)), and study conclusions. Eight RCTs were identified as meeting all inclusion criteria and were thus included in the data synthesis. The findings from these trials revealed a diverse range of nonpharmacological physical therapy interventions, including but not limited to manual therapy, exercise therapy, and multimodal approaches. Specifically, the interventions demonstrated significant improvements in headache scores, strength, pain levels, and overall QOL among individuals with CGH. These results underscore the multifaceted benefits of physical therapy in managing CGH and highlight its potential as a comprehensive treatment option. This review identified eight relevant RCTs investigating nonpharmacological interventions for CGH. Despite the promising findings, this review acknowledges several limitations, including the limited sample size and the heterogeneity of interventions across studies. These limitations emphasize the necessity for further research to elucidate optimal intervention strategies and refine treatment protocols. Nevertheless, the comprehensive analysis presented herein reinforces the pivotal role of physical therapy in not only alleviating pain but also enhancing function and improving the QOL for individuals suffering from CGH.

[Complementary and supplementary procedures in the treatment of headache]

In Germany, headache is one of the illnesses that most frequently leads to health impairments and to consultation with physicians. Even in children, headache is often associated with restricted activities of daily life. Nevertheless, the level of care for headache disorders is disproportionate to the medical needs. As a result, patients regularly use complementary and supportive therapeutic procedures. This review shows the procedures currently used for primary headache in childhood and adulthood, the methodological approaches and existing scientific evidence. The safety of the therapeutic options is also classified. These methods include physiotherapy, neural therapy, acupuncture, homeopathy, phytotherapy and the intake of dietary supplements. For children and adolescents with headaches, there are studies in the field of dietary supplements for coenzyme Q10, riboflavin, magnesium and vitamin D, which indicate specific effects in the reduction of headaches.

Therapeutic Exercise Parameters, Considerations, and Recommendations for Migraine Treatment: An International Delphi Study

OBJECTIVE

The goal of this study was to reach consensus about the best exercise prescription parameters, the most relevant considerations, and other recommendations that could be useful for prescribing exercise to patients with migraine.

METHODS

This was an international study conducted between April 9, 2022 and June 30, 2022. An expert panel of health care and exercise professionals was assembled, and a 3-round Delphi survey was performed. Consensus was reached for each item if an Aiken V Validity Index ≥ 0.7 was obtained.

RESULTS

The study included 14 experts who reached consensus on 42 items by the third round. The most approved prescription parameters were 30 to 60 minutes of exercise per session, 3 days per week of moderate-intensity continuous aerobic exercise, and relaxation and breathing exercises for 5 to 20 minutes every day. When considering an exercise prescription, initial exercise supervision should progress to patient self-regulation; catastrophizing, fear-avoidance beliefs, headache-related disability, anxiety, depression, physical activity baseline level, and self-efficacy could influence the patients' exercise participation and efficacy; and gradual exposure to exercise could help improve these psychological variables and increase exercise efficacy. Yoga and concurrent exercise were also included as recommended interventions.

CONCLUSION

From the experts in the study, exercise prescriptions should be adapted to patients with migraine considering different exercise modalities, such as moderate-intensity aerobic exercise, relaxation, yoga, and concurrent exercise, based on the patients' preferences and psychological considerations, level of physical activity, and possible adverse effects.

IMPACT

The consensus reached by the experts can help prescribe exercise accurately to patients with migraine. Offering various exercise modalities can improve exercise participation in this population. The evaluation of the patients' psychological and physical status can also facilitate the adaptation of the exercise prescription to their abilities and diminish the risk of adverse events.

Effectiveness of therapeutic exercise for the management of cervicogenic headache: A systematic review

OBJECTIVE

The main aim of this systematic review is to evaluate the effectiveness of therapeutic exercise for managing pain and disability in patients with cervicogenic headache (CEH).

METHODS

A protocol for this systematic review was published in PROSPERO (CRD42019122703). PRISMA and AMSTAR2 standards were followed. Based on an extensive systematic search in five databases (EMBASE, MEDLINE, CINHAL, PsychInfo and SportDISCUS) and the CENTRAL trial register, two reviewers carefully and independently assessed, selected results, collected data, rated the risk of bias (RoB) of included studies with the Cochrane risk of bias tool, synthesized the available evidence, and rated it using GRADE methodology.

RESULTS

A total of 12 manuscripts, reporting on 11 studies were included. Most studies showed a high risk of bias (63,63%). Additionally, a great deal of heterogeneity was observed regarding interventions, comparisons, and outcomes and thus, results could not be synthesized in meta-analyses. The quality of the evidence was found to be from low to very low. Significant differences with large effect sizes were found when comparing multimodal exercise vs. control groups on headache outcomes (SMD = 0.73; 95%CI [0.31, 1.14] for headache intensity and SMD = 0.98; 95%CI [0.56, 1.41], for headache frequency).

CONCLUSIONS

Findings indicate that therapeutic exercise may be effective to achieve clinically relevant reductions in headache intensity and frequency as well as disability for patients suffering from cervicogenic headache. However, more high-quality research is needed to gain confidence in this finding and possibly determine optimal types and dosage of therapeutic exercise.

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.

Effect of aerobic exercises and therapeutic pain neuroscience education on disability, pain, head posture and QOL in migraine patients

Migraine is a type of primary headache with a high degree of associated disability that can present with a variety of indications and co-morbidities. The role of physical therapy treatment in migraine management is largely obscure. To investigate the combine effect of aerobic exercises and therapeutic pain neuroscience education on disability, pain pressure threshold, head posture and quality of life (QoL) in patients having migraine. Subjects were screened by using Migraine Disability Assessment (MIDAS) and after screening total sample of 50 subjects were randomly assigned into two groups: Group A (Experimental, n=25) and Group B (Control, n=25). Migraine disability assessment, pressure algometer, craniovertebral angle (CVA) and migraine specific quality of life were examined before and after 6 weeks of the intervention. Group A were given aerobic exercises and therapeutic pain neuroscience education along with conventional treatment for 45 min 3 days/week for 6 weeks, whereas participants in the Group B performed conventional exercises alone for 20 min 3 days/week for 6 weeks. Significant differences were observed in migraine disability score (P=0.003) and pain pressure threshold (P=0.039, P=0.030 and P=0.025) and improvement in forward head posture (P=0.001) between the groups after the intervention period, signifying greater improvement in the group A. QoL also improved in both the groups after intervention. Main findings of the present study suggest that the therapeutic pain neuroscience education and aerobic exercises combined with conventional treatment together maybe helpful to give better quality of life, reduced disability, increased pain pressure threshold and increased CVA to patients with migraine.

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.

Effectiveness of manual therapy in the treatment of cervicogenic headache: A systematic review

OBJECTIVE

The aim of this study was to identify the manual therapy (MT) methods and techniques that have been evaluated for the treatment of cervicogenic headache (CH) and their effectiveness.

BACKGROUND

MT seems to be one of the options with the greatest potential for the treatment of CH, but the techniques to be applied are varied and there is no consensus on which are the most indicated.

METHODS

A systematic search in Scopus, Medline, PubMed, Cinahl, PEDro, and Web of Science with the terms: secondary headache disorders, physical therapy modalities, musculoskeletal manipulations, cervicogenic headache, manual therapy, and physical therapy. We included articles published from 2015 to the present that studied interventions with MT techniques in patients with CH. Two reviewers independently screened 365 articles for demographic information, characteristics of study design, study-specific intervention, and results. The Oxford 2011 Levels of Evidence and the Jadad scale were used.

RESULTS

Of a total of 14 articles selected, 11 were randomized control trials and three were quasi-experimental studies. The techniques studied were: spinal manipulative therapy, Mulligan's Sustained Natural Apophyseal Glides, muscle techniques, and translatory vertebral mobilization. In the short-term, the Jones technique on the trapezius and ischemic compression on the sternocleidomastoid achieved immediate improvements, whereas adding spinal manipulative therapy to the treatment can maintain long-term results.

CONCLUSIONS

The manual therapy techniques could be effective in the treatment of patients with CH. The combined use of MT techniques improved the results compared with using them separately. This review has methodological limitations, such as the inclusion of quasi-experimental studies and studies with small sample sizes that reduced the generalizability of the results obtained.

Pain relief by movement representation strategies: An umbrella and mapping review with meta-meta-analysis of motor imagery, action observation and mirror therapy

OBJECTIVE

To develop a mapping and umbrella review with a meta-meta-analysis (MMA) to critically evaluate the current evidence of motor imagery (MI), action observation and mirror therapy (MT) on pain intensity.

METHODS

The study involved a systematic search of PubMed, PEDro, Scielo, EBSCO and Google Scholar.

RESULTS

Ten systematic reviews were included in the qualitative synthesis, 70% of which showed high methodological quality. Three reviews found a significant reduction in chronic musculoskeletal pain as the result of applying movement representation methods (MRM) plus usual-care (UC), with a large clinical effect (standardized mean difference [SMD] of -1.47; 95% CI -2.05 to -0.88; heterogeneity Q = 1.66; p = 0.44; I²  = 0%). However, two reviews showed no statistically significant reduction in acute and postsurgical pain as a result of applying MI plus UC. Four reviews showed no significant reduction in phantom limb pain (PLP) as a result of applying MT plus UC interventions. In four reviews, the MMA showed a significant reduction in complex regional pain syndrome (CRPS) as a result of applying MT plus UC, with a large clinical effect (SMD -1.27; 95% CI -1.87 to -0.67; heterogeneity Q = 3.95; p = 0.27; I²  = 24%). In two reviews, the MMA showed no significant differences in poststroke pain as a result of applying MT plus UC.

CONCLUSION

Results show that MRM could be effective for chronic musculoskeletal pain, with low to moderate-quality evidence. The results also show a reduction in pain intensity through MT interventions in patients with CRPS, although these results were not found in patients with PLP or poststroke pain.

SIGNIFICANCE

This umbrella review analysed systematic reviews evaluating movement representation techniques, with the aim of synthesizing the available evidence regarding motor imagery, action observation and mirror therapy on pain. The results provide relevant information about the potential clinical use of movement representation techniques in different types of patients with painful conditions.
