Effects of Different Exercise Intensities on Headache: A Systematic Review

Multistrategic Approaches in the Treatment of Acute Migraine During Pregnancy: The Effectiveness of Physiotherapy, Exercise, and Relaxation Techniques

Background and Objectives: Migraine is a common neurological condition that significantly impacts quality of life, especially in women during their reproductive years. Pregnancy poses unique challenges for migraine management due to hormonal changes and the limited use of pharmacological treatments. Non-pharmacological interventions, such as physiotherapy, exercise, and relaxation techniques, offer promising alternatives for managing migraines during this critical period. This study aims to evaluate the effectiveness of physiotherapy, structured exercise, and relaxation techniques in reducing migraine frequency, severity, and duration while improving psychosocial outcomes such as quality of life, stress levels, and sleep quality in pregnant women. Materials and Methods: Sixty pregnant women diagnosed with acute migraine were randomly assigned into three intervention groups: physiotherapy, structured exercise, and relaxation techniques. Each intervention lasted 8 weeks. The primary outcomes included migraine frequency, severity (measured by VAS), and duration. The secondary outcomes included quality of life (SF-36), stress (PSS), and sleep quality (PSQI). Statistical analyses were conducted using one-way ANOVA and paired t-tests. Results: All interventions significantly reduced migraine frequency, severity, and duration (p < 0.05). Physiotherapy demonstrated the greatest reduction in migraine frequency (45%) and severity (36%), while exercise yielded the most significant improvement in duration (42%). Relaxation techniques were particularly effective in reducing stress and anxiety levels. Quality of life and sleep quality improved across all groups, with unique benefits observed for each intervention. Conclusions: Physiotherapy, structured exercise, and relaxation techniques are effective, safe, and non-invasive interventions for managing acute migraines during pregnancy. These findings provide evidence-based alternatives to pharmacological treatments, highlighting the importance of holistic approaches to migraine management during pregnancy. Further research is needed to confirm long-term efficacy and explore combined interventions.

Evaluating a 12-week aerobic exercise intervention in adults with persisting post-concussive symptoms

Background

Although guidelines support aerobic exercise in sub-acute mild traumatic brain injury (mTBI), evidence for adults with persisting post-concussive symptoms (PPCS) after mTBI is lacking. The objective was to evaluate the impact of a sub-symptom threshold aerobic exercise intervention on overall symptom burden and quality of life in adults with PPCS.

Methods

This prospective cohort study was nested within the ACTBI Trial (Aerobic Exercise for treatment of Chronic symptoms following mild Traumatic Brain Injury). A total of 50 adults with a diagnosis of mTBI, PPCS and exercise intolerance completed a 12-week sub-symptom threshold aerobic exercise intervention either immediately after enrollment (i-AEP group; n = 27) or following 6-weeks of stretching (d-AEP group; n = 23). Data from all participants (n = 50) were included in the combined AEP (c-AEP) group. The primary outcome was symptom burden on the Rivermead Post Concussion Symptoms Questionnaire (RPQ). Secondary outcomes included measures of quality of life and specific post-concussive symptoms (depressive and anxiety symptoms, functional impact of headache, fatigue, sleep, dizziness and exercise tolerance). Heart rate, blood pressure and heart rate variability were also assessed to understand autonomic function response to intervention.

Results

Participants were a mean (SD) of 42.6 (10.9) years old (74% female) and 25.1 (14.1) months post-mTBI. Following 12-weeks of intervention participants had a significant improvement in symptom burden on the RPQ (i-AEP: mean change = -9.415, p < 0.001; d-AEP: mean change = -3.478, p = 0.034; c-AEP: mean change = -6.446, p < 0.001). Participants also had significant improvement in quality of life (i-AEP: mean change = 9.879, p < 0.001; d-AEP: mean change = 7.994, p < 0.001, c-AEP: mean change = 8.937, p < 0.001), dizziness (i-AEP: mean change = -11.159, p = 0.001; d-AEP: mean change = -6.516, p = 0.019; c-AEP: -8.837, p < 0.001) and exercise tolerance (i-AEP: mean change = 5.987, p < 0.001; d-AEP: mean change = 3.421, p < 0.001; c-AEP: mean change = 4.703, p < 0.001). Headache (mean change = -5.522, p < 0.001) and depressive symptoms (mean change = -3.032, p = 0.001) improved in the i-AEP group. There was no change in measures of autonomic function.

Conclusion

A 12-week aerobic exercise intervention improves overall symptom burden, quality of life and specific symptom domains in adults with PPCS. Clinicians should consider prescription of progressive, individualized, sub-symptom threshold aerobic exercise for adults with PPCS even if presenting with exercise intolerance and months-to-years of symptoms.

Pain Perception, Knowledge, Attitude, and Diet Diversity in Patients Undergoing Fixed Orthodontic Treatment: A Pilot Study

Objective

This study aimed to determine the correlation between pain perception and knowledge, attitude, and diet diversity in patients undergoing fixed orthodontic treatment.

Methods

A total of 103 patients (15-40 yrs.; 67 females, 36 males) undergoing orthodontic treatment with a 0.022-inch slot (MBT prescription) in both arches were recruited. Information on pain perception, knowledge, attitude, and diet diversity scores was collected through validated questionnaires using visual analogue scale and close-ended questions at one time point. The correlation between variables was analyzed using the Pearson's correlation coefficient.

Results

Of the patients, 48.5% were aged 15 to 19 years old, with 65% females and 73.8% of Chinese ethnicity. Approximately 90% of the orthodontic patients perceived low levels of pain from orthodontic treatment, and 98% had a positive attitude toward orthodontic treatment. The patients had a good level of knowledge (Mean: 6±0.65). Approximately 49.5% of patients reported having moderate diet diversity. No significant correlation was found between pain perception and knowledge, or pain perception and diet diversity (r=0.062, p=0.534). However, a significant weak negative correlation (r=-0.289, p<0.05) between pain perception and attitude was observed.

Conclusion

Patients undergoing fixed orthodontic treatment presented with overall low pain perception, a positive attitude, and good knowledge about their treatment with moderate diet diversity. Informing the patient in advance about different orthodontic procedures encourages a positive attitude and facilitates patient cooperation. An interprofessional approach involving nutritionists can provide a holistic patient approach during orthodontic treatment.

[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.

Mind the Metabolic Gap: Bridging Migraine and Alzheimer's disease through Brain Insulin Resistance

Brain insulin resistance has recently been described as a metabolic abnormality of brain glucose homeostasis that has been proven to downregulate insulin receptors, both in astrocytes and neurons, triggering a reduction in glucose uptake and glycogen synthesis. This condition may generate a mismatch between brain's energy reserve and expenditure, ??mainly during high metabolic demand, which could be involved in the chronification of migraine and, in the long run, at least in certain subsets of patients, in the prodromic phase of Alzheimer's disease, along a putative metabolic physiopathological continuum. Indeed, the persistent disruption of glucose homeostasis and energy supply to neurons may eventually impair protein folding, an energy-requiring process, promoting pathological changes in Alzheimer's disease, such as amyloid-β deposition and tau hyperphosphorylation. Hopefully, the "neuroenergetic hypothesis" presented herein will provide further insight on there being a conceivable metabolic bridge between chronic migraine and Alzheimer's disease, elucidating novel potential targets for the prophylactic treatment of both diseases.

Effects of cervical stabilization training in patients with headache: A single-blinded randomized controlled trial

BACKGROUND

This study aimed to investigate the effects of Cervical Stabilization Training (CST) on the headache, neck pain and cervical musculoskeletal system in patients with headache compared to the control group.

METHODS

A total of 90 female patients with migraine, tension-type headache and cervicogenic headache (CGH) participated in this study. The patients were divided into the cervical stabilization training group (CSTG) and the control group (CG). The CSTG performed the CST three times a week for 8 weeks while the CG continued their ongoing medical treatment. The pain intensity was assessed by Visual Analogue Scale, forward head posture by craniovertebral angle measurement, the endurance of deep cervical flexor muscles by craniocervical flexion test and the endurance of cervical muscles by flexor and extensor endurance tests before and after 8 weeks. In addition, disability levels, health-related quality of life, sleep quality and mood were assessed by the Migraine Disability Assessment questionnaire, Neck Disability Index (NDI), Short Form 36 Quality of Life Scale, the Pittsburgh Sleep Quality Index and Beck Depression Scale, respectively.

RESULTS

Headache frequency, duration and intensity, neck pain intensity and forward head posture reduced while activation and performance of deep cervical flexor muscles, the endurance of cervical flexor and extensor muscles increased in the CSTG (p < 0.05). Furthermore, the disability levels, quality of life, sleep quality and mood also improved in the CSTG (p < 0.05).

CONCLUSIONS

This study suggests that CST reduces headaches and neck pain by improving the cervical musculoskeletal system in patients with headache.

SIGNIFICANCE

The CST improved the headache frequency, duration and intensity, neck pain intensity, cervical posture, activation of deep cervical flexor muscles and endurance of cervical muscles in patients with headache. In addition, improvements in the cervical musculoskeletal system contributed to a reduction in the intensity of headaches and neck pain. Therefore, CST may be preferred in the treatment of headaches, especially with coexisting neck pain.

Exploring downstream effects of gender roles in healthcare decision-making and relationships within systems: A cross-sectional analysis of openness to treatment in pediatric headache

OBJECTIVE

Socio-culturally defined identity factors present significant and often understudied influences on the experience, management, and treatment of chronic pain. For instance, there exist societal narratives about how males and females are expected to experience and express pain. Such gender roles may impact youth and caregiver openness to individual multidisciplinary treatments for pediatric headache.

METHODS

In this cross-sectional study, participants (N = 1087 youth/caregiver dyads, Mage = 14.5 years, 71% female, 97% cisgender, 77% White) completed a series of questionnaires, including Openness to Headache Treatment (OHT), upon presenting for initial multidisciplinary evaluation of chronic headache. Pearson correlations, independent samples t-tests and hierarchical regressions were used to analyze potential gender differences in youth and caregiver openness, as well as its relationships with pain-related and psychological factors.

RESULTS

Overall, female youth and their caregivers were more open to headache treatment, broadly and for individual interventions, when compared to male counterparts. Caregiver distress related to their child's headaches (i.e., fear and avoidance) was significantly correlated with openness in female youth and their caregivers, but not males.

CONCLUSION

Gendered patterns in healthcare decision-making in youth and caregivers provide insight on individual, societal, and systemic gender bias.

Neck-Shoulder Region Training for Chronic Headache in Women: A Randomized Controlled Trial

OBJECTIVES

We investigated whether a specific exercise program for the neck-shoulder region reduces headache intensity, frequency, and duration, and how it influences neck disability among women with chronic headache compared to a control group.

DESIGN

Two-center randomized controlled trial.

SUBJECTS

116 working-age women.

INTERVENTION

The exercise group (n = 57) performed a home-based program with six progressive exercise modules, over 6 months. The control group (n = 59) underwent six placebo-dosed transcutaneous electrical nerve stimulation sessions. Both groups performed stretching exercises.

MAIN MEASURES

The primary outcome was pain intensity of headache, assessed using the Numeric Pain Rating Scale. Secondary outcomes were frequency and duration of weekly headaches, and neck disability assessed using the Neck Disability Index. Generalized linear mixed models were used.

RESULTS

Mean pain intensity at baseline was 4.7 (95% CI 4.4 to 5.0) in the exercise group and 4.8 (4.5 to 5.1) in the control group. After 6 months the decrease was slight with no between-group difference. Headache frequency decreased from 4.5 (3.9 to 5.1) to 2.4 (1.8 to 3.0) days/week in the exercise group, and from 4.4 (3.6 to 5.1) to 3.0 (2.4 to 3.6) in the control group (between-group p = 0.017). Headache duration decreased in both groups, with no between-group difference. Greater improvement in the Neck Disability Index was found in the exercise group (between-group change -1.6 [95% CI -3.1 to -0.2] points).

CONCLUSION

The progressive exercise program almost halved headache frequency. The exercise program could be recommended as one treatment option for women with chronic headache.

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.

Depression, anxiety and stress in Saudi migraine patients using DASS-21: local population-based cross-sectional survey

Background: Psychiatric comorbidity is common among migraineurs, such as anxiety and depression. This type of comorbidity contributed to migraine chronicity, management efficacy, and increasing the risk for other comorbidities. This study designed to estimate the prevalence of depression, anxiety, and stress (DAS) symptoms among Saudi migraine patients using the validated instrument (DASS-21) and considering socio-demographic factors and individual differences that affect migraine progression and prognosis.Design/methods: Cross-sectional, self-administered, web-based-questionnaire distributed among Saudi Arabia general population. Only migraine patients with clinical diagnosis allowed to complete the survey.Results: A total of 247 migraine patients participated and they are predominantly females, with ages between 16 and 45 years, Saudi nationals, married, non-smokers but do not exercise regularly. About 73.3% met the abnormal score in anxiety on DASS-21, as well as 70.9% in depression and 72.3% in stress. Four statistically significant correlations with DAS were identified. Migraine patients who are smoking have a higher prevalence of depression and stress (p < 0.05). Those who do not exercise regularly have a higher prevalence only for depression (p = 0.03). A higher prevalence of all emotional states was found in patients with more than one co-morbidity and patients with a clinical diagnosis of depression and anxiety disorders (p < 0.02). The sensitivity of DASS-21 for depression and anxiety are 96.9% and 93.3%, respectively.Conclusions: Both smoking cessation and exercise to prevent migraine attacks deserve a clinical trial. A holistic approach is needed to decrease psychiatry-related disability and promote management outcomes in migraineurs. Using DASS-21 for migraine patients as a routine screening instrument is valuable to prevent psychiatric comorbidity.

Effects of acupuncture and medical training therapy on depression, anxiety, and quality of life in patients with frequent tension-type headache: A randomized controlled study

OBJECTIVES

To compare the effects of acupuncture and medical training therapy in combination or individually with usual care on quality of life, depression, and anxiety in patients with tension-type headache.

METHODS

In this single-center, prospective, randomized, controlled, unblinded trial, 96 adults (38.7(+/-13.3) years of age; 75 females/20 males/one dropout) with frequent episodic or chronic tension-type headache were randomized to one of four treatment groups (n = 24). The treatment groups received six weeks of either acupuncture or medical training therapy as monotherapies or in combination (12 interventions each), or usual care. We assessed depressiveness (PHQ-9), anxiety (GAD-7), and health-related quality of life (SF-12) as secondary outcome parameters at baseline, six weeks, three months, and six months after initiation of treatment. Linear mixed models were calculated.

RESULTS

Both, acupuncture (baseline to six-weeks change scores: mean: -2(standard deviation: 2.5 points), three months: -2.4(2.4), six-months -2.7(3.6)) and the combination of acupuncture and medical training therapy (-2.7(4.9), -2.2(4.0), -2.2(4.2)) (each within-group p < .05) significantly reduced depressiveness-scores (PHQ-9) to a greater extent than medical training therapy (-0.3(2.0), -0.5(1.6), -0.9(2.6)) or usual care alone (-0.8(2.9), 0.1(2.8), 0.2(3.6)). We found similar results with anxiety scores and the physical sum scores of the SF-12. No severe adverse events occurred.

CONCLUSIONS

Acupuncture and the combination of acupuncture and medical training therapy elicit positive effects on depression, anxiety, quality of life, and symptom intensity in patients with episodic and chronic tension-type headache. Acupuncture appears to play a central role in mediating the therapeutic effects, underscoring the clinical relevance of this treatment. An additive benefit of the combination of both therapies does not appear to be relevant.Trial registration: Registered on 11 February 2019. German Clinical Trials Register, DRKS00016723.

Headache in Workers: A Matched Case-Control Study

A case−control study including 446 workers reporting headaches (cases; 136 males and 310 females, mean age 46.71 ± 10.84 years) and 446 age- and sex-matched colleagues without headaches (controls; mean age 45.44 ± 10.13) was conducted in the second half of 2020 in a sample drawn from socio health and commercial services companies to investigate the association of headache with lifestyle, metabolic, and work-related factors. Workers suffering from headache reported higher body weight (OR: 1.92, 95% CI: 1.46−2.53, p < 0.001), higher blood cholesterol (OR: 2.01, 95% CI: 1.46−2.77, p < 0.001), triglyceride (OR: 2.01, 95% CI: 1.20−3.35, p < 0.01), blood glucose (OR: 1.91, 95% CI: 1.16−3.24, p < 0.01), and blood pressure levels (OR: 1.76, 95% CI: 1.23−2.52, p < 0.01). In the year preceding the survey, cases had experienced a higher frequency of workplace violence (OR: 2.29, 95% CI: 1.25−4.20, p < 0.01 for physical aggression, OR: 2.22, 95% CI: 1.45−3.41, p < 0.001 for threat, OR: 2.74, 95% CI: 1.72−4.38, p < 0.001 for harassment) and were more frequently distressed (effort/reward ratio > 1) (OR: 1.82, 95% CI: 1.39−2.40, p < 0.001) than the controls. Compared to the controls, cases also had higher scores on anxiety and depression scales, lower scores on happiness, and lower levels of sleep quality (p < 0.001). The association of headaches with metabolic and mental health problems suggests that monitoring headaches in the workplace could help to identify workers at risk of impairment.

Migraine, Brain Glucose Metabolism and the "Neuroenergetic" Hypothesis: A Scoping Review

Increasing evidence suggests that migraine may be the result of an impaired brain glucose metabolism. Several studies have reported brain mitochondrial dysfunction, impaired brain glucose metabolism and gray matter volume reduction in specific brain areas of migraineurs. Furthermore, peripheral insulin resistance, a condition demonstrated in several studies, may extend to the brain, leading to brain insulin resistance. This condition has been proven to downregulate insulin receptors, both in astrocytes and neurons, triggering a reduction in glucose uptake and glycogen synthesis, mainly during high metabolic demand. This scoping review examines the clinical, epidemiologic and pathophysiologic data supporting the hypothesis that abnormalities in brain glucose metabolism may generate a mismatch between the brain's energy reserve and metabolic expenditure, triggering migraine attacks. Moreover, alteration in glucose homeostasis could generate a chronic brain energy deficit promoting migraine chronification. Lastly, insulin resistance may link migraine with its comorbidities, like obesity, depression, cognitive impairment and cerebrovascular diseases. PERSPECTIVE: Although additional experimental studies are needed to support this novel "neuroenergetic" hypothesis, brain insulin resistance in migraineurs may unravel the pathophysiological mechanisms of the disease, explaining the migraine chronification and connecting migraine with comorbidities. Therefore, this hypothesis could elucidate novel potential approaches for migraine treatment.

Physical Activity is Associated with Less Analgesic Use in Women Reporting Headache-A Cross-Sectional Study of the German Migraine and Headache Society (DMKG)

INTRODUCTION

The aim of this analysis is to determine whether regular physical activity is associated with less analgesic use in men and women suffering from headache disorders based on population-based cross-sectional data.

METHODS

We used data from a random general population sample in Germany that comprised 2477 participants aged ≥ 14 years. A standardized questionnaire addressing headache and headache treatment was filled in during the face-to-face survey.

RESULTS

Thirty-nine percent of the participants reported headache. Of these, 37.5% of men and 33.6% of women were physically active. Of the participants with headache, 43.3% reported taking analgesics on < 2 days a month, 40.7% on 2-5 days a month, 10.1% on 6-10 days a month, and 5.9% on > 10 days a month. Frequent headache, severe impact of headache on daily life, and depressive symptoms were associated with higher analgesic use in both men and women. For women, physical inactivity was associated with the frequency of analgesic use adjusted for sociodemographic and headache-related variables. For men, results did not suggest any association between physical inactivity and frequency of analgesic use.

CONCLUSIONS

There are both sex-unspecific and sex-specific factors associated with analgesic use among men and women with headache. In women with increased analgesic use, promoting physical activity may reduce analgesic use. For men, education about the therapeutic effects of physical activity for headaches is an important resource.

Exercise and Manual Therapy for the Treatment of Primary Headache: An Umbrella and Mapping Review

OBJECTIVE

The main aim of this study was to assess through systematic review the efficacy of exercise and manual therapy (MT) interventions in individuals with primary headache.

METHODS

In this umbrella review, 2 authors reviewed systematic reviews by searching the Cochrane Database of Systematic Reviews, MEDLINE, PEDro, Web of Science, and Google Scholar. Systematic reviews that evaluated the effectiveness of MT. Exercise-based interventions, or both in patients with primary headaches were included. Methodological quality was analyzed using the ROBIS scale, and the strength of evidence was established according to the Grading Criteria of the Physical Activity Guidelines Advisory Committee.

RESULTS

Thirty-one systematic reviews containing 79 trials and involving 9103 patients were included. The 7 exercise-related systematic reviews reported beneficial effects on primary headache based on unclear to moderate evidence. Of the 23 MT-related systematic reviews, 11 reported enhanced effectiveness compared with usual care; however, overall heterogeneity and risk of bias were high. Systematic reviews that evaluated the effectiveness of MT, exercise-based interventions, or both in patients with primary headaches were included.

CONCLUSION

Results show that exercise could be an effective therapy for the treatment of primary headache, with moderate to limited quality of evidence regarding the positive effects in terms of pain intensity and frequency and duration of headache. Moderate quality of evidence was found regarding the ability of MT to reduce pain intensity in patients with tension-type headaches, but quality of evidence was limited in terms of frequency of headache and disability and pain reduction in patients with migraine.

IMPACT

Exercise could be an effective treatment in patients with primary headache. Manual therapy showed limited evidence to reduce pain intensity in patients with tension-type headache. It is not possible to establish a preferential exercise protocol or MT program, so psychosocial and behavioral variables need to be considered in future studies.

Effects of Different Therapeutic Exercise Modalities on Migraine or Tension-Type Headache: A Systematic Review and Meta-Analysis with a Replicability Analysis

The primary aim of this study was to review the effect of exercise in comparison with a non-active treatment on pain intensity, frequency of headache episodes, headache duration, quality of life, medication use, and psychological symptoms, in patients with migraine or tension-type headache (TTH). A systematic search was conducted in various electronic databases to identify all relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of exercise interventions in patients with primary headaches were selected. Methodological quality was evaluated using the Cochrane Risk of Bias Tool and PEDro scale and qualitative analysis was based on classifying the results into levels of evidence according to the GRADE. 19 studies (2776 participants; 85% female) were included. The meta-analysis showed statistically significant differences in pain intensity for aerobic training in patients with migraine (SMD = -0.65; 95% CI = -1.07 to -0.22, very low certainty evidence) and for strength training in patients with TTH (SMD = -0.84; 95% CI = -1.68 to- -0.01, very low certainty evidence). Statistically significant differences were also found in the medication use (SMD = -0.51; 95% CI = -0.85 to -0.17, low certainty evidence). Low transparency, replicability and high risk of bias were found. Aerobic training has a small to moderate clinical effect on pain intensity and medication use on migraine patients, with very low to low certainty of evidence. Strength training showed a moderate clinical effect with very low quality of evidence in patients with TTH. Exercise could be considered as clinically relevant for the management of patients with primary headaches, but the presence of low certainty of evidence and low transparency and replicability limited its clinical application. PERSPECTIVE: This article presents current evidence about exercise interventions in patients with primary headaches, including migraine and tension-type headache. Existing findings are reviewed, and relevant data are provided on the effectiveness of each exercise modality, as well as its certainty of evidence and clinical applicability.

Effects of therapeutic and aerobic exercise programs in temporomandibular disorder-associated headaches

Objective

To assess the effects of three 8-week exercise programs on the frequency, intensity, and impact of headaches in patients with headache attributed to temporomandibular disorder (TMD).

Methodology

Thirty-six patients diagnosed with headache attributed to TMD participated in the study and were divided into three groups of 12 patients: a therapeutic exercise program (G1, mean age: 26.3±5.6 years), a therapeutic and aerobic exercise program (G2, mean age: 26.0±4.6 years), and an aerobic exercise program (G3, 25.8±2.94 years). Headache frequency and intensity were evaluated using a headache diary, and the adverse headache impact was evaluated using the Headache Impact Test (HIT-6). The intensity was reported using the numerical pain rating scale. These parameters were evaluated twice at baseline (A01/A02), at the end of the 8-week intervention period (A1), and 8–12 weeks after the end of the intervention (A2).

Results

At A1, none of the G2 patients reported having headaches, in G1, only two patients reported headaches, and in G3, ten patients reported headache. The headache intensity scores (0.3 [95% CI: -0.401, 1.068]), (0.0 [95% CI: -0.734, 0.734]) and HIT-6 (50.7 [95% CI: 38.008, 63.459]), (49.5 [95% CI: 36.808, 62.259]), significantly decreased in G1 and G2 at A1. At A2 headache intensity scores (0.5 [95% CI: -0.256, 1.256]), (0.0 [95% CI: -0.756, 0.756]) and HIT-6 (55.1 [95% CI: 42.998, 67.268]), (51.7 [95% CI: 39.532, 63.802]) in G1 and G2 haven’t change significantly. The effects obtained immediately after the completion of the intervention programs were maintained until the final follow-up in all groups.

Conclusion

The programs conducted by G1 (therapeutic exercises) and G2 (therapeutic and aerobic exercise) had significant results at A1 and A2.

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

The aim of the study was to perform a mapping and umbrella review with meta-meta-analysis (MMA) to synthesise and critically evaluate the effectiveness of manual therapy (MT) and aerobic exercise (AE) in relation to pain intensity, frequency, disability and quality of life in patients with migraines, tension-type headaches (TTH) and cervicogenic headaches (CGH). A systematic search was conducted in PubMed, PEDro, Scielo and Google Scholar up to December 2020. A total of 18 articles met the inclusion criteria, and only 8 were included in the quantitative analysis. The MMA showed results in favour of the interventions in terms of pain intensity and quality of life in migraine, TTH and CCH. Data were also in favour of the intervention in terms of pain frequency in migraine and in terms of disability in TTH. However, there were no significant effects on pain frequency in TTH and CGH. The results showed moderate evidence to suggest that AE reduces pain intensity in patients with migraine. In addition, the evidence in favour of MT or a mixed intervention (including therapeutic exercise) was also moderate in terms of reducing pain intensity in patients with TTH.

Clinical Reasoning Behind Non-Pharmacological Interventions for the Management of Headaches: A Narrative Literature Review

Headache is the clinical syndrome most commonly observed by neurologists in daily practice. Pharmacological and non-pharmacological treatments are commonly used for the management of headaches; however, the clinical reasoning behind these interventions is not properly applied. We conducted a narrative literature review using as data sources for academic PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, PEDro, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, and SCOPUS. This narrative literature review mainly considered systematic reviews, meta-analyses, randomised clinical trials, and expert opinions published after the year 2000 discussing clinical reasoning for application of non-pharmacological interventions in individuals with tension-type, migraine, and cervicogenic headaches. After the data extraction, we organized the literature thematically as follows: (1) mapping of theoretical aspects of non-pharmacological interventions; (2) summarizing most updated literature about effectiveness of non-pharmacological interventions grouped by targeted tissue and headache; (3) identifying research gaps in the existing literature and proposing hypotheses for better understanding of current clinical reasoning. We found that there are many non-pharmacological treatment strategies used for headaches, including beyond the tissue-based impairment treatments (bottom-up) and strategies targeting the central nervous system (top down). Bottom-up strategies include joint-biased, soft-tissue biased, or needling interventions, whereas top-down strategies include exercise and cognitive interventions. Evidence shows that the effectiveness of these interventions depends on the application of proper clinical reasoning, since not all strategies are effective for all headaches. For instance, evidence of non-pharmacological interventions is more controversial for migraines than for tension-type or cervicogenic headaches, since migraine pathogenesis involves activation of sub-cortical structures and the trigemino- vascular system, whereas pathogenesis of tension-type or cervicogenic headaches is most associated to musculoskeletal impairments of the cervical spine. We conclude that current literature suggests that not all non-pharmacological interventions are effective for all headaches, and that multimodal, not isolated, approaches seem to be more effective for patients with headaches. Most published studies have reported small clinical effects in the short term. This narrative literature review provides some hypotheses for discrepancies in the available literature and future research. Clinical reasoning should be applied to better understand the effects of non-pharmacological interventions.

Neck-specific strengthening exercise compared with sham ultrasound when added to home-stretching exercise in patients with migraine: study protocol of a two-armed, parallel-groups randomized controlled trial

BACKGROUND

Migraine is a highly disabling condition and pharmacological treatment is the gold standard. However, several patients have also positive responses to the application of different manual techniques and therapeutic exercises in terms of reducing the intensity and frequency of migraine attacks. Nevertheless, the effects of a neck-specific exercise program have not yet been evaluated in these patients.

OBJECTIVE

To determine the effectiveness of a neck-specific exercise program in reducing the intensity and frequency of migraine attacks as compared to a sham ultrasound group.

METHODS

A two-armed, parallel-groups randomized controlled trial with 3 months of follow-up will be conducted. 42 individuals, both genders, aged between 18 and 55 years old with a medical diagnosis of migraine will be included. The intervention group will perform a protocol consisting of exercises for strengthening the muscles of the cervical spine. Participants within the sham ultrasound group will receive detuned ultrasound therapy in the upper trapezius muscle. Both groups will receive a weekly session for 8 weeks. The efficacy of each intervention will be measured by the frequency and intensity of migraine at a 3-months follow-up.

TRIAL REGISTRATION

This study was registered under access code RBT-8gfv5j in the Registro Brasileiro de Ensaios Clínicos (ReBEC) in November 28, 2016.

CONCLUSION

This study will aim to determine the efficacy of a neck-specific exercise program in reducing the frequency and intensity of migraine attacks. If the results show that a neck-specific exercise program is effective in reducing the frequency and intensity of migraine attacks, therapists will have a low cost and easily applicable tool to treat migraine.
