Level of physical activity, well-being, stress and self-rated health in persons with migraine and co-existing tension-type headache and neck pain

Neck pain associated with headache attributed to rhinosinusitis: an observational study

BACKGROUND

Neck pain is common among people with headache, including migraines, tension headache, and cervicogenic headache. Neck pain has also been associated with self-reported sinus headache in individuals who were not formally diagnosed with headache attributed to rhinosinusitis (HAR). Neck pain, in individuals diagnosed with HAR according to the International Classification of Headache Disorders, has not been investigated.

OBJECTIVE

The primary objective of this study was to compare the report of neck pain in people with and without HAR. A secondary purpose was to compare measures of cervical musculoskeletal dysfunction between groups.

METHODS

This was an observational study. There were 80 total participants, age and sex-matched with 40 per group. HAR group participants completed the Headache Impact Test, Sino-Nasal Outcome Test-22, Neck Disability Index (NDI), and Visual Analog Scale Score (VASS) to rate headache. All participants underwent examination of neck range of motion, neck muscle endurance, and segmental examination.

RESULTS

There were significant between-group differences for reported neck pain (82.5% in HAR group; 22.5% in control group, p < .001) and NDI score (mean difference [95% CI] = 15.7 [11.1, 20.2], p < .001). There was a moderate and significant positive correlation between HAR and segmental dysfunction in the upper cervical spine (O-C3) (0.425, p < .001) but not the lower cervical spine.

CONCLUSION

Neck pain may be associated with HAR, and patients perceive this neck pain as impacting their quality of life. Upper cervical segmental dysfunction was common and significantly different in the HAR group. Causation of both the subjective and objective findings remains unclear.

Exercise in early pregnancy among women with migraine: A hospital-based cross-sectional study

OBJECTIVE

Migraine is one of the most common pain disorders among women of childbearing age. While medical treatment might be necessary for some during pregnancy, non-pharmacological approaches, such as exercise, are generally recommended. We aimed to assess the association between migraine and exercise behaviours, adherence to the national recommendations for exercise, and the type of exercise undertaken during early pregnancy within a cohort of Danish women.

METHODS

We performed a cross-sectional study using patient-reported questionnaire data from The Copenhagen Pregnancy Cohort (2013-2019). Logistic regression analyses were applied to assess associations between migraine and the selected outcomes, with adjustment for relevant confounders.

RESULTS

We included 24,017 pregnancies. Women with migraine were more likely to refrain from exercise in early pregnancy compared to those without (46.4% vs 40.8%) (aOR 1.26, 95% CI 1.12-1.41). Additionally, they were more likely not to meet the national recommendations for exercise (62.9% vs 57.8%), (aOR 1.27, 95% CI 1.13-1.42). The differences were consistent among women with migraine with aura (MA) and migraine without aura (MO), respectively. Women with and without migraine participated in similar types of exercise during early pregnancy.

CONCLUSIONS

Our findings indicate that women with migraine were less likely to engage in exercise and to adhere to the national recommendations of exercise, compared to those without. Findings were similar for women with MA and MO. The types of exercise performed did not differ between groups.

General physical impairments in migraine patients beyond cervical function

Previous research has focused on the possibility of cervical dysfunction in migraine patients, similar to what is observed in patients with tension-type headaches. However, there is no evidence concerning the physical function of other body regions, even though lower levels of physical activity have been reported among migraine patients. The aim of this study was to compare cervical and extra-cervical range of motion, muscular strength, and endurance, as well as overall levels of physical activity, between patients with chronic migraine (CM) and asymptomatic participants. The secondary objective included the analysis of associations between CM-related disability and various physical and psychological variables. A total of 90 participants were included in this cross-sectional study: 30 asymptomatic participants (AG) and 60 patients with CM. Cervical and lumbar range of motion, strength and endurance, as well as handgrip strength were measured. Headache-related disability, kinesiophobia, pain behaviors, physical activity level and headache frequency were assessed through a self-report. Lower values were found in CM vs AG for cervical and lumbar ranges of motion (p < 0.05; effect sizes ranging from 0.57 to 1.44). Also, for neck extension strength (p = 0.013; d = - 0.66), lumbar strength (p < 0.001; d = - 1.91) and handgrip strength (p < 0.001; d = - 0.98), neck endurance (p < 0.001; d = - 1.81) and lumbar endurance (p < 0.001; d = - 2.11). Significant differences were found for physical activity levels (p = 0.01; d = - 0.85) and kinesiophobia (p < 0.001; d = - 0.93) between CM and AG. Headache-related disability was strongly associated with headache frequency, activity avoidance, and rest, which together explained 41% of the variance. The main findings of this study suggest that patients with CM have a generalized fitness deficit and not specifically cervical dysfunction. These findings support the hypothesis that migraine patients have not only neck-related issues but also general body conditions.

Reduction of neck pain severity in patients with medication-overuse headache

BACKGROUND

Neck pain and primary headache disorders are highly prevalent in populations and clinical cohorts. Medication-overuse headache (MOH) is a treatable secondary headache, mainly developing in migraine sufferers, that accounts for the majority of patients presenting to headache clinics. Nevertheless, the association between neck pain and MOH has not been reported. This study evaluated the prevalence and clinical course of neck pain in patients with MOH before and after MOH treatment.

METHODS

We analyzed 635 MOH patients enrolled in a nationwide, prospective, multicenter MOH registry. Demographics and clinical data were collected at baseline and 3 months to evaluate changes in the status and severity of neck pain and headache. Severity of neck pain was graded into 4 groups, and severe neck pain was defined as grade 3 or 4.

RESULTS

Among 635 patients with MOH, 366 (57.6%) reported neck pain at baseline. MOH patients with neck pain had an earlier onset of their primary headache disorder (23.4 ± 12.7 vs. 26.2 ± 13.3 years, p = 0.007). Although monthly headache days were comparable between the patients with neck pain and those without neck pain, the neck pain group had higher levels of anxiety (7.4 ± 5.8 vs. 6.4 ± 5.4, p = 0.017), more severe cutaneous allodynia (2.4 ± 3.3 vs. 1.8 ± 3.0, p = 0.038), and poorer quality of life (171.7 ± 70.4 vs. 184.0 ± 68.9, p = 0.029). At 3 months, 456 (71.8%) were followed-up, and 257 (56.4%) were recovered from MOH. Compared to the baseline, the proportion of severe neck pain (40.4% vs. 19.4%, p < 0.001) was decreased. The proportion of severe neck pain was much lower in patients with recovery from MOH compared to those without (4.7% vs. 15.1%, p < 0.001).

CONCLUSIONS

Neck pain in MOH patients was associated with earlier onset of headache, higher levels of anxiety and allodynia, and poorer quality of life. Improvement in neck pain improvement was linked to recovery from MOH. These findings suggest the potential importance of integrating and management of neck pain into clinical practice for MOH.

Evaluation of forward head posture and thoracic kyphosis in migraine

BACKGROUND

The purpose of the current study was to investigate the forward head posture (FHP), thoracic kyphosis and their relationships between individuals with migraine and healthy controls using the DIERS Formetric 4D motion imaging system.

METHODS

In this observational case-control study, a total of 39 migraine patients and 44 healthy subjects were enrolled. FHP and thoracic kyphosis were assessed by using the 4D Formetric DIERS system. The visual analogue scale (VAS) and Neck Disability Index (NDI) was used to evaluate neck pain and neck disability. Headache status were evaluated through Migraine Disability Assessment (MIDAS) and Numeric Pain Rating Scale (NPRS) questionnaires.

RESULTS

The fleche cervicale (57.72 ± 13.72 mm vs. 40.00 ± 4.75 mm; p < 0.001) and kyphotic angle (57.39 ± 8.76° vs. 38.21 ± 5.67°; p < 0.001) were significantly higher in patients with migraine compared to control group. When NDI categories were compared, the migraine group showed significantly increase in the number of patients with moderate or severe disability (p < 0.001). A positive correlation was found between fleche cervicale and thoracic kyphosis (r = 0.71, p < 0.001).

CONCLUSIONS

This study revealed that patients with migraine exhibited a greater FHP and thoracic kyphosis compared to the control group. A 3-dimensional objective measurement may be a reliable diagnostic tool to evaluate posture analysis in clinical practice in the future.

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.

Neck Pain Disability on Headache Impact and the Association between Sleep Disturbance and Neck Pain in Migraine

Neck pain (NP) is a prevalent symptom among migraine patients, but its disability on headache impact and the contributing factors for comorbid NP are poorly understood. This study aimed to investigate NP disability on the impact of headaches among migraineurs and factors linked to comorbid NP, including sleep-related variables. This cross-sectional study was conducted at a university hospital headache center, for headache patients at their first visits. Included in the study were 295 patients with migraines (217 females; 39.0  ±  10.8 years; 101 chronic migraine). Information on NP, history of physician-diagnosed cervical spine or disc disorders, detailed parameters of headache, and sleep and mood variables were collected. Logistic analysis of the severe impact of headache and contributing factors for NP were performed. NP was present in 153 participants (51.9%) with migraine, with high NP disability observed in 28 patients, and 125 patients had low NP disability. In multivariable analysis, NP disability, medication days per month, severe disability of migraine, and excessive daytime sleepiness were significant predictors for severe impact of headache. Thirty-seven patients with physician-diagnosed cervical spine or disc disorders were excluded from the NP analysis. Higher monthly headache days, female gender, and a high likelihood of obstructive sleep apnea were positively correlated with the presence of NP among migraineurs in multivariable analysis. Overall, the study highlights the potential impact of sleep-related variables and monthly headache days on NP in these patients. The high disability of NP was also associated with severe impact of headache.

Sex Differences in Clinical Features, Treatment, and Lifestyle Factors in Patients With Cluster Headache

BACKGROUND AND OBJECTIVES

Cluster headache is considered a male-dominated disorder, but we have previously suggested that female patients may display a more severe phenotype. Studies on sex differences in cluster headache have been conflicting; therefore, this study, with the largest validated cluster headache material at present, gives more insights into sex-specific characteristics of the disease. The objective of this study was to describe sex differences in patient demographics, clinical phenotype, chronobiology, triggers, treatment, and lifestyle in a Swedish cluster headache population.

METHODS

Study participants were identified by screening medical records from 2014 to 2020, requested from hospitals and neurology clinics in Sweden for the ICD-10 code G44.0 for cluster headache. Each study participant answered a detailed questionnaire on clinical information and lifestyle, and all variables were compared with regard to sex.

RESULTS

A total of 874 study participants with a verified cluster headache diagnosis were included. Of the participants, 575 (66%) were male and 299 (34%) were female, and biological sex matched self-reported sex for all. Female participants were to a greater extent diagnosed with the chronic cluster headache subtype compared with male participants (18% vs 9%, p = 0.0002). In line with this observation, female participants report longer bouts than male participants (p = 0.003) and used prophylactic treatment more often (60% vs 48%, p = 0.0005). Regarding associated symptoms, female participants experienced ptosis (61% vs 47%, p = 0.0002) and restlessness (54% vs 46%, p = 0.02) more frequently compared with male participants. More female than male study participants had a positive family history of cluster headache (15% vs 7%, p = 0.0002). In addition, female participants reported diurnal rhythmicity of their attacks more often than male participants (74% vs 63%, p = 0.002). Alcohol as a trigger occurred more frequently in male participants (54% vs 48%, p = 0.01), whereas lack of sleep triggering an attack was more common in female participants (31% vs 20%, p = 0.001).

DISCUSSION

With this in-depth analysis of a well-characterized cluster headache population, we could demonstrate that there are significant differences between male and female participants with cluster headache, which should be regarded at the time of diagnosis and when choosing treatment options. The data suggest that female patients generally may be more gravely affected by cluster headache than male patients.

Pain sensitivity in relation to frequency of migraine and tension-type headache with or without coexistent neck pain: an exploratory secondary analysis of the population study

OBJECTIVES

We aimed to investigate whether coexistent self-reported neck pain influences cephalic and extracephalic pain sensitivity in individuals with migraine and tension-type headache (TTH) in relation to diagnosis and headache frequency.

METHODS

A population of 496 individuals completed a headache interview based on ICHD criteria, providing data collected by self-administered questionnaires, assessments of pericranial total tenderness score (TTS) and pressure pain thresholds (PPT). Stimulus-response (SR) functions for pressure vs. pain were recorded. Presence of neck pain in the past year was assessed by the self-administered questionnaire. We categorized participants by primary headache type. We also categorized participants into 3 groups by headache frequency: chronic (≥15) or episodic (<15 headache days/month) headache and controls. TTS, PPTs and the area under the SR curve were compared between subgroups using Generalized Linear Models with pairwise comparisons controlling for age and sex.

RESULTS

Individuals with chronic followed by episodic headache had higher TTS than controls (overall p≤0.001). The difference between chronic and episodic headache subgroups was significant in the group with neck pain (p≤0.001) but not in the group without neck pain. In individuals with neck pain, mean TTS was higher in coexistent headache (migraine and TTH), 23.2 ± 10.7, and pure TTH, 17.8 ± 10.3, compared to pure migraine, 15.9 ± 10.9 and no headache 11.0 ± 8.3 (overall p<0.001). Temporal and finger PPTs did not statistically differ among the chronic headache, the episodic headache and controls in individuals with and without neck pain. Temporalis and trapezius SR-functions showed that tenderness was increased in individuals with chronic headache to higher degree than in those with episodic headache, and more so in those with neck pain.

CONCLUSIONS

Coexistent neck pain is associated with greater pericranial tenderness in individuals with chronic headache and to a lesser degree in those with episodic headache. Sensitization may be a substrate or consequence of neck pain and primary headache, but a longitudinal study would be needed for further clarification.

Modifiable factors for migraine prophylaxis: A mendelian randomization analysis

Objective: To examine the causal effect of potentially modifiable risk factors contributing to migraine pathogenesis. Methods: We performed Mendelian randomization analyses and acquired data from United Kingdom Biobank, FinnGen Biobank, and the MRC IEU OpenGWAS data infrastructure. An inverse-variance weighted (IVW) model was used to examine the relationship between 51 potentially modifiable risk factors and migraine in 3215 participants with migraine without aura (MwoA), 3541 participants with migraine with aura (MwA), and 176,107 controls. We adopted a Bonferroni-corrected threshold of p = 9.8 × 10-4 (.05 divided by 51 exposures) as a sign of significant effect, and a p < .05 was considered as the sign of a suggestive association. Results: More years of schooling significantly correlated with lower odds of MwoA pathogenesis (OR .57 [95%CI .44 to .75], p < .0001). More vitamin B12 intake (OR .49 [95%CI .24 to .99], p = .046) and lower level of stress [OR 8.17 (95%CI 1.5 to 44.36), p = .015] or anxiety disorder (OR 1.92 × 109 [95%CI 8.76 to 4.23*1017], p = .029) were suggestive to be correlated lower odds of MwoA pathogenesis. More coffee intake (OR .39 [95%CI .22 to .7], p = .001), lower level of eicosapentaenoic acid status (OR 2.54 [95%CI 1.03 to 6.26], p = .043), and more light physical activity (OR .09 [95%CI .01 to .94], p = .046) were suggestive to be associated with lower odds of MwA. Conclusion: The years of schooling, light physical activity, vitamin B12 intake, and coffee intake were the protective factors for migraine; stress, anxiety, and eicosapentaenoic acid status were harmful factors. Interventions could be developed based on modifying these factors for migraine prophylaxis.

Migraine and obesity: what is the real direction of their association?

INTRODUCTION

In recent decades, studies have addressed the issue of how migraine and obesity are related and have suggested obesity as a risk factor for migraine headache. However, the exact direction of this relationship remains under debate. In this review, the authors summarize the evidence that have suggested migraine as a risk factor for obesity and overweightness.

AREAS COVERED

This article reviews the results of the previous research published on PubMed and Scopus databases (from 2000 to 2020) concerning the association between migraine and obesity to determine the actual direction of their association. Special attention has been given to the common mechanistic pathways involved in the pathophysiology of migraine and obesity.

EXPERT OPINION

The majority of research conducted thus far has considered obesity as a risk factor for migraine. However, because of the cross-sectional design of available research, we cannot be certain of the proposed direction of this association. There is evidence supporting the hypothesis that obesity can serve as a consequence of migraine through the effects of neuropeptides, inflammatory mediators, adipokines, gut microbiota and modifications in eating behavior and lifestyle. However, the real direction of the relationship between migraine and obesity should be further investigated in large prospective studies.

Fitts' Tapping Task as a New Test for Cognition and Manual Dexterity in Multiple Sclerosis: Validation Study

Introduction. Studies suggest that people with multiple sclerosis (pwMS) experience continuous and subclinical physical worsening, even as early as their disease diagnosis. Validating sensitive and reproducible tests that can capture subclinical disease activity early in the disease are clinically useful and highly warranted. We aimed at validating the utility of Fitts’ Tapping Task (FTT) as reproducible measure of psychomotor performance in pwMS. Materials and Methods. Thirty newly-diagnosed pwMS (within 2 years of diagnosis and Expanded Disability Status Scale; EDSS ≤ 2.0), 30 people with migraine (pwMig), and 30 healthy controls (HCs) underwent a psychomotor assessment using the FTT, O’Connor hand dexterity test, and Visual Reaction Time Test (VRTT). Hand strength was measured using a hand-grip dynamometer. Subjects also provided patient-reported outcomes (PROs) using the 36-Item Short Form Survey (SF-36). Intrarater and interrater reproducibility was acquired on 5 HCs by two independent operators. Test−retest reproducibility was determined in 5 pwMS over a 1-week follow-up. Eight pwMS returned for the same test procedures 2 years after the baseline assessment. Bland−Altman plots were used to determine the minimally detectable change (MDC) and logistic regression models determined the ability to differentiate between newly-diagnosed pwMS and HCs. Results. FTT exhibited a high intrarater and interrater reproducibility (interclass correlation coefficient of 0.961, p < 0.001). The test−retest demonstrated an MDC of the average FTT at > 15%. PwMS had significantly a slower FTT time and O’Connor dexterity time when compared to pwMig and HCs (p < 0.001 for both). Higher Fitts’ difficulty levels (4th and 6th difficulty) and average performance on the O’Connor test were able to differentiate newly-diagnosed pwMS from HCs with 80% accuracy (p < 0.01). Slower FTT performance was correlated with worse PROs due to physical health. Over the 2-year follow-up, and despite being clinically stable (no change in EDSS), 6 out of 8 (75%) pwMS had more than a 15% worsening in their average FTT time. Conclusions. FTT is a highly-reproducible test for measuring psychomotor performance in newly-diagnosed pwMS. FTT can capture insidious worsening in psychomotor performance and cognitive function in early stages of MS.

Does the Intensity of the Headache Differ According to the Level of Neck Disability in Chronic Migraine Patients?

Chronic migraine (CM) patients who report a high frequency and intensity of headaches also report neck pain (NP) and neck disability (ND) in neck activities that require stability. In this context, CM patients may report different headache intensities at different levels of ND. Our aim in this study is to investigate whether the intensity of headaches differs according to the level of ND in CM patients. Headache intensity and NP intensity were evaluated with the Visual Analog Scale (VAS), and ND was evaluated with the Neck Disability Index (NDI). A total of 142 patients who met the inclusion criteria were included in the study. The mean age was 53.24 ± 12.08 years. The median number of monthly headache days was 20. According to VAS, the median headache intensity was 10(4-10) cm and the median of NP intensity was 9(1-10) cm. The mean NDI was 28.45 ± 10.28. There was a difference in headache intensity between mild and severe disability levels (p = 0.007, Z = -3.289); headache intensity between mild and complete disability levels (p = 0.000, Z = -4.421); and headache intensity between moderate and complete disability levels (p = 0.004, Z = -2.212). Although the difference in headache intensity between ND levels is small, a median increase of 2 cm in headache intensity at mild ND levels may result in complete ND. A median increase of 1 cm in headache intensity at the moderate ND level may cause complete disability in the neck. According to our results, the intensity of headaches of CM patients differed according to the level of ND. We consider our results to be clinically important in this context.

Effects of Physical Exercise on Mobile Phone Addiction in College Students: The Chain Mediation Effect of Psychological Resilience and Perceived Stress

Smartphones have become an integral part of people's daily lives. While bringing convenience, mobile phone addiction caused by overuse of smart phones has become a common phenomenon among college students. The current study aimed to examine the serial mediating role of psychological resilience and perceived stress between physical exercise and mobile phone addiction of college students. Using the PARS-3 scale, CD-RISC-10 scale, PSS-10 scale, and MPA scale, 257 college students were investigated and Structural Equation Model (SEM) was conducted. The results show that: (1) Physical exercise has no significant direct impact on mobile phone addiction. (2) Psychological resilience has a significant mediating effect between physical exercise and mobile phone addiction. But perceived stress does not. (3) Psychological resilience and perceived stress play a chain mediation role. Physical exercise can enhance psychological resilience firstly, thus relieving perceived stress and eventually mitigating mobile phone addiction.

Stress-induced headache in the general working population is moderated by the NRCAM rs2300043 genotype

OBJECTIVES

Earlier findings suggest that social stress such as abusive supervision may promote pain. In the present study we examine the possible moderating role of genetic variability in the NRCAM gene in this process.

METHODS

The data were collected through a national survey drawn from the National Central Employee Register by Statistics Norway. A total of 1,205 individuals returned both the questionnaire and the saliva kit. Abusive supervision was scored by a 5-item version of the Tepper's 2,000 scale. Headache was measured on a four-category scale; 'not bothered,' 'a little bothered,' 'considerably bothered', 'seriously bothered'. Genotyping with regards to NRCAM rs2300043 was carried out using Taqman assay. Ordinal logistic regression was used to analyse the data.

RESULTS

For males exposed to abusive supervision, those carrying the rs2300043 CC genotype reported the highest levels of headache. Women showed a trend towards the opposite pattern. Women with the rs2300043 CC genotype seem to have a weaker effect of abusive supervision regarding reported headache than their male counterparts with the CC genotype when exposed to abusive supervision.

CONCLUSIONS

The present results indicated that the association between abusive supervision and headache in men with the NRCAM rs2300043 C allele was stronger than in other men. This suggests that the NRCAM genotype in men is important for the tolerance of social stress e.g., repeated negative acts from a superior. In contrast, a trend, though non-significant, towards the opposite pattern was observed in women. Our result suggests that the NRCAM genotype in men manifestly affects stress-induced pain such as headache.

Relationship between Self-Efficacy and Headache Impact, Anxiety, and Physical Activity Levels in Patients with Chronic Tension-Type Headache: An Observational Study

Background

Chronic tension-type headache is the primary headache with the highest prevalence. The present study is aimed at analyzing the associations between patient self-efficacy and headache impact with pain characteristics, kinesiophobia, anxiety sensitivity, and physical activity levels in subjects with chronic tension-type headache.

Materials and Methods

An observational descriptive study was carried out. A total sample of 42 participants was recruited at university environment with diagnosis of tension-type headache. Headache characteristics (frequency, intensity, and duration), physical activity levels, pain related-self-efficacy, kinesiophobia, anxiety sensitivity, and headache impact were measured.

Results

The HIT-6 (61.05 ± 6.38) score showed significant moderate positive correlations with the ASI-3 score (17.64 ± 16.22; r = 0.47) and moderate negative correlations with the self-efficacy in the domains of pain management (31.9 ± 10.28; r = -0.43) and coping with symptoms (53.81 ± 14.19; r = -0.47). ASI-3 score had a negative large correlation with self-efficacy in the domains of pain management (r = -0.59), physical function (53.36 ± 7.99; r = -0.55), and coping with symptoms (r = -0.68). Physical activity levels showed positive moderate correlations with the self-efficacy in the domain of physical function (r = 0.41). Linear regression models determined that the self-efficacy and anxiety sensitivity with showed a significant relationship with the HIT-6 score (R 2 = 0.262; p = 0.008) and with the ASI-3 score (R 2 = 0.565; p < 0.001). In addition, no correlations were found between pain intensity, duration or frecuency with psychosocial factors, or headache impact.

Conclusions

The present study showed that patients with chronic tension-type headache had a great negative impact on daily tasks and physical activity levels, which were associated with higher anxiety levels and lower self-efficacy.

Impact of the Neck and/or Shoulder Pain on Self-reported Headache Treatment Responses – Results From a Pharmacy-Based Patient Survey

Neck and/or shoulder pain (NSP) frequently occurs together with headache. Therefore, we explored how patients with and without concomitant NSP differ in their baseline characteristics and in perceived treatment responses to an analgesic. An anonymous survey was performed among 895 patients with headache (735 self-reported tension-type headache [TTH]) who used an analgesic fixed-dose combination containing 400 mg ibuprofen and 100 mg caffeine as a non-prescription treatment. NSP was abundant among patients in our survey (60%) and was associated with >1 additional day of headache per month. Patients with NSP reported predominantly sedentary work more frequently than those without (40 vs. 29%); they also reported physical tension/poor posture as a perceived trigger factor more frequently (70 vs. 16%). The reported pain reduction was comparable in those with and without concomitant NSP regardless of whether assessed as mean pain rating (from about 6 to 1.5 on a 10-point rating scale), patients experiencing a ≥50% in pain reduction (89.6 vs. 88.8%) or becoming pain-free within 2 h (57 vs. 64%). However, recurrence of pain and use of another dose within the same day were more frequent with than without NSP. We conclude that concomitant NSP is frequent in patients with headache but does not substantially alter responses to a non-prescription medication.

Deep Cervical Muscles and Functionality in Patients with Chronic Tension-Type Headache: An Observational Study

Background and objectives: Chronic tension-type headache (TTH) is the type of headache with the highest prevalence. The involvement of musculoskeletal structures in TTH is supported by evidence in the scientific literature. Among these, deep cervical muscle strength appears to be related to the function of the cervical spine and the clinical characteristics of TTH. This study aimed to correlate anatomical, functional, and psychological variables in patients with TTH. Materials and methods: An observational descriptive study was carried out with 22 participants diagnosed with TTH for at least six months. The characteristics of headaches, including ultrasound-based deep neck flexor and extensor muscle thickness, range of motion (ROM), and pressure pain threshold (PPT), were recorded. We also conducted the Pain Vigilance and Awareness Questionnaire (PVAQ) and the Craniocervical Flexion Test (CCFT). Results: Moderate-large negative correlations were found between the PVAQ and the muscle thickness of right deep flexors contracted (r = -0.52; p = 0.01), left multifidus contracted (r = -0.44; p = 0.04), right multifidus at rest (r = -0.48; p = 0.02), and right multifidus contracted (r = -0.45; p = 0.04). Moderate-large positive correlations were found between the CCFT score and the left cervical rotation ROM (r = 0.53; p = 0.01), right cervical rotation ROM (r = 0.48; p = 0.03), muscle thickness of left multifidus contracted (r = 0.50; p = 0.02), and muscle thickness of right multifidus at rest (r = 0.51; p = 0.02). The muscle thickness of the contracted right deep cervical flexors showed a moderate negative correlation with headache intensity (r = -0.464; p = 0.03). No correlations were found between PPT and the rest of the variables analyzed. Conclusions: In patients with TTH, a higher thickness of deep cervical muscles was associated with higher ROM and higher scores in the CCFT. In turn, the thickness of deep cervical muscles showed negative correlations with pain hypervigilance and headache intensity. These results contribute to a better understanding of the physical and psychosocial factors contributing to the development of TTH, which is useful for implementing appropriate prevention and treatment measures.

The Neck Disability Index Reflects Allodynia and Headache Disability but Not Cervical Musculoskeletal Dysfunction in Migraine

OBJECTIVE

The Neck Disability Index (NDI) is a self-rated disability tool originally developed for whiplash-associated disorders and validated in cervical musculoskeletal conditions. It is now commonly used to assess neck disability in migraine, but it is unknown whether NDI scores relate to migraine and hypersensitivity, cervical musculoskeletal dysfunction, or both. This single-blinded observational study aimed to determine whether the presence of cervical musculoskeletal dysfunction, migraine features, and hypersensitivity predict NDI scores and whether alternate versions of the NDI (NDI-physical, NDI-8, NDI-5) relate more to cervical musculoskeletal dysfunction.

METHODS

Migraine and neck pain features, the Headache Impact Test (HIT-6), NDI, Allodynia Symptom Checklist (ASC12), and pressure pain thresholds were assessed in 104 participants with migraine and neck pain, 45 previously identified with cervical musculoskeletal dysfunction and 59 without. The NDI score was regressed on the presence or absence of cervical dysfunction, migraine features, HIT-6, total pressure pain threshold, and ASC12 while accounting for neck pain features. The presence of cervical dysfunction was regressed on the scores of NDI versions.

RESULTS

The ASC12 (standardized ß = 0.20) and HIT-6 (standardized ß = 0.18) were significantly predictive of total NDI score, as were neck pain intensity (standardized ß = 0.32) and frequency (standardized ß = 0.44). No scores from alternate NDI versions related to cervical dysfunction.

CONCLUSION

The NDI score is a complex measure of neck disability influenced by migraine disability and hypersensitivity beyond the presence of cervical musculoskeletal dysfunction. This has implications for the clinical interpretation of NDI scores in patients with migraine.

IMPACT

Many patients with migraine and neck pain report neck disability; therefore, it is important to understand if migraine impacts neck disability. The results of this study indicate that clinicians need to consider migraine-related disability and hypersensitivity when managing neck disability in this population.

Cognitive or daily stress association with headache and pain induction in migraine and tension-type headache patients: a systematic review

INTRODUCTION

Primary headache disorders, such as migraine and tension-type headache (TTH), represent a significant public health concern. Besides, cognitive/mental stress was suggested to contribute to TTH and migraine physiopathology. Thus, this study aimed to evaluate the existence of a causal relationship between stress (mental/cognitive or daily stress) and headache or pain improvement in migraine and TTH patients.

AREAS COVERED

We developed a systematic review of the literature, including studies that utilized mental/cognitive stress tasks or daily stress by lifestyle questionnaire in migraine and TTH patients. Necessarily, these studies should have healthy patients and a pain measure (quantitative sensory tests or headache/migraine detection). PubMed, EMBASE, and SCOPUS were searched, using terms about stress and primary headaches.

EXPERT OPINION

Both mental/cognitive stress and daily stress (perceived) were related to an increase in pain perception and related to the development of headache or enhanced transient pain intensity in migraine and TTH patients. Different factors could enrich the comprehension of the influence of stress on pain/headache induction in migraine and TTH patients, including methodological standardization, consistency of assessing, and isolating the many headache triggers in randomized controlled trial studies.

Cervical musculoskeletal impairments in migraine

Background

Neck pain is common and disabling amongst individuals with migraine. Cervical musculoskeletal interventions are often sought but there is currently no evidence to support such interventions for this population. Improved understanding of how cervical musculoskeletal impairments present in migraine can elucidate neck pain mechanisms and guide clinicians and researchers in the management of patients with migraine and neck pain.

Main body

Migraine hypersensitivity is a major consideration when assessing for cervical impairments as it can aggravate migraine and confound findings. Current evidence of cervical impairments in migraine is limited by disregard for the different underlying causes of neck pain and possible influence of hypersensitivity. Findings of cervical musculoskeletal impairments are mixed within and across studies, indicating that different forms of neck pain are present in migraine. Some migraineurs have neck pain that is part of the migraine symptom complex and therefore exhibit little or no cervical musculoskeletal impairment. Others have a cervical source of neck pain and therefore exhibit a pattern of cervical musculoskeletal impairments akin to that of cervical disorders. The presence of cervical musculoskeletal dysfunction may or may not be related to migraine but knowledge of this is currently lacking which impacts decision making on management. Cervical musculoskeletal interventions may be indicated for migraineurs with identified cervical dysfunction but other factors requiring further clarification include determination of i) patient specific outcomes, ii) impact of co-existing migraine referred neck pain, and iii) potential moderating effects of migraine hypersensitivity on treatment efficacy.

Conclusions

Physiotherapists should seek a combination of cervical impairments through skilful assessment to identify if cervical musculoskeletal dysfunction is present or not in individual patients. The relevance of cervical dysfunction to migraine and influence of co-existing migraine referred neck pain need to be established through detailed evaluation of pain behaviours and further research. Future clinical trials should define expected treatment outcomes and select individuals with cervical musculoskeletal dysfunction when investigating the efficacy of cervical musculoskeletal interventions.

A Prospective Real-World Study Exploring Associations Between Passively Collected Tracker Data and Headache Burden Among Individuals with Tension-Type Headache and Migraine

Introduction

Prevalence and burden of headache disorders in real-world settings is relatively unstudied. We explored the associations between passively collected activity data, headache burden, and quality of life in headache sufferers.

Methods

Data from wearable activity tracking devices and daily short questionnaires were collected over 12 weeks to assess occurrence of headache, activity, quality of life and self-rated health. Variables were analyzed using a series of mixed-effects models and stratified based on headache type. Multiple linear and logistic regressions were used to analyze treatment preferences.

Results

Behaviors inferred from activity tracker data suggested that individuals slept more, had reduced physical activity, and had lower maximum heart rate on days with headache. As headache-specific impact on quality of life increased, activity and maximum heart rate decreased and sleep increased. Headache days with higher self-rated health were associated with less napping, higher step count and maximum heart rate, correlating with increased activity. Migraineurs experienced greater burden in everyday life compared with tension-type headache sufferers.

Conclusion

This study adds to existing evidence that activity trackers can be used to quantify headache burden in real-world settings and aid in understanding symptom management.

Alteration of Relative Rates of Biodegradation and Regeneration of Cervical Spine Cartilage through the Restoration of Arterial Blood Flow Access to Rhomboid Fossa: A Hypothesis

We found the logical way to prove the existence of the mechanism that maintains the rates of biodegradation and regeneration of cervical spine cartilage. We demonstrate, that after we restore access to arterial blood flow through cervical vertebral arteries to rhomboid fossa it causes the prevalence of regeneration over biodegradation. This is in the frames of consideration of the human body as a dissipative structure. Then the recovery of the body should be considered as a reduction of the relative rates of decay below the regeneration ones. Then the recovery of cervical spine cartilage through redirecting of inner dissipative flow depends on the information about oxygen availability that is provided from oxygen detectors in the rhomboid fossa to the cerebellum. Our proposed approach explains already collected data, which satisfies all the scientific requirements. This allows us to draw conclusions that permit reconsidering the way of dealing with multiple chronic diseases.

Mental pain and pain-proneness in patients with migraine: results from the PAINMIG cohort-study

BACKGROUND

Pain has been qualified under four categories: nociception, perception of pain, suffering, and pain behaviors. Most of the literature on migraine has devoted attention to the first two. The aim of the present cohort study was to investigate patients with migraine enrolled at a tertiary care unit to study suffering and mental pain and identify potential risk factors for migraine.

METHODS

An observational cross-sectional study was carried out on patients with chronic migraine (CM) and episodic migraine (EM), and healthy subjects (HS). The three groups were matched for age and sex. A comprehensive assessment of migraine disability, pain, psychiatric disorders, psychosomatic syndromes, depressive and anxious symptoms, euthymia, psychosocial variables, mental pain, and pain-proneness (PP) was performed.

RESULTS

Three hundred subjects were enrolled (100 CM, 100 EM, and 100 HS). Based on the multiple regression analyses, those presenting PP (social impairment: odds ratio [OR] = 3.59, 95% confidence interval [CI] = 1.14-11.29; depressive symptoms: OR = 3.82, 95% CI = 1.74-8.41) were more likely to be CM than HS. Those with higher levels of PP (social impairment: OR = 4.04, 95% CI = 1.60-10.22; depressive symptoms: OR = 2.02, 95% CI = 1.26-3.24) were more likely to be EM than HS. Those presenting higher levels of mental pain were more likely to be CM than EM (OR = 1.45, 95% CI = 1.02-2.07).

CONCLUSION

Migraine is an unpleasant sensory and emotional experience associated with psychosocial manifestations that might contribute to the level of suffering of the individuals. Mental pain resulted to be the variable that most differentiated patients with CM from EM.

Are Physical Activities Associated With Perceived Stress? The Evidence From the China Health and Nutrition Survey

Psychological stress is a negative affective state. The association between physical activity and psychological stress was commonly reported in previous researches. Few published studies with large sample sizes have explored such an association in Chinese population. The current research aims to assess the association between perceived stress and physical activity preferences, as well as the association between risk of high perceived stress and physical activity behaviors (e.g., sports-, transport-, occupational-related physical activity, sedentary activities and time in bed). The data were collected from the China Health and Nutrition Survey (CHNS) in 2015. Generalized linear models and logistic regression models were used to explore the association between perceived stress and physical activity. In total, 11,066 participants were included in the current analysis. For physical activity preferences, we found that “like” preference of all six mentioned domains of activities contributed to lower perceived stress (i.e., lower perceived stress scale −14 score, all β < 0 and p < 0.05). For physical activity behaviors, the results indicated that none/low intensity physical activity behaviors (e.g., sports-, occupational- related, sedentary) were associated with risk of high perceived stress, except that low intensity of transport-related activities seemed to be protective from high stress. However, the association between intensity of physical activity behaviors and perceived stress was not simply the higher the better. High intensity of all these physical activity behaviors was also associated with high perceived stress. Our findings suggest that positive preferences and moderate physical activity behaviors were associated with low perceived stress. The findings herein highlight the effect of regulating physical activity on perceived stress, as well as inform potential strategies to reduce psychological stress.

Physical inactivity and headache disorders: Cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

BACKGROUND

Physical inactivity has been linked to headache disorders but estimates based on the current World Health Organization physical activity guidelines are unknown.

OBJECTIVE

To test the associations between headache disorders and physical inactivity in the ELSA-Brasil cohort.

METHODS

In a cross-sectional analysis, linear (continuous variables) and logistic regression models (categorical variables) tested the associations of physical activity levels in the leisure time, commuting time, and combined leisure time physical activity + commuting time physical activity domains with headache disorders, adjusted for the effects of sociodemographic data, cardiovascular risk variables, psychiatric disorders, and migraine prophylaxis medication.

RESULTS

Of 15,105 participants, 14,847 (54.4% women) provided data on physical activity levels and headache. Higher physical activity levels (continuous values) in the leisure time physical activity domain associated with lower migraine and tension-type headache occurrence and lower headache attack frequency, while in the commuting time physical activity domain it associated with more frequent headache attacks. Compared to people who met World Health Organization physical activity levels in the leisure time physical activity or combining leisure time physical activity + commuting time physical activity domains (i.e. ≥150 min.wk^-1 of moderate and/or ≥75 min.wk^-1 of vigorous physical activity), physical inactivity associated with higher migraine occurrence, while somewhat active (i.e. not meeting World Health Organization recommendations) associated with higher migraine and tension-type headache occurrence. Physical inactivity in the commuting time physical activity domain associated with higher tension-type headache in men and lower migraine in women. Physical inactivity within vigorous leisure time physical activity intensity, but not moderate leisure time physical activity, associated with higher migraine, mostly in women. Finally, physical inactivity associated with higher headache attack frequency regardless headache subtype.

CONCLUSION

Physical inactivity and unmet World Health Organization physical activity levels associate with primary headaches, with heterogeneous associations regarding headache subtype, sex, physical activity domain/intensity, and headache frequency in the ELSA-Brasil study.

The Relationship Among Pain Location, Complications, and Quality of Life in Individuals With Fibromuscular Dysplasia

BACKGROUND

Fibromuscular dysplasia (FMD), a nonatherosclerotic arterial disease, can cause pain and vascular complications. The aim of this study was to examine the impact of FMD symptoms and complications on quality of life, depression, anxiety, and self-rated health.

DESIGN

This was a cross-sectional, correlational study.

METHODS

Participants were adults with a diagnosis of FMD. Quality of life (36-Item Short Form Health Survey), anxiety and depression (Patient-Reported Outcomes Measurement Information System [PROMIS®]), self-rated health question, and symptom/complication questionnaires were mailed to patients with FMD. Scores were compared with symptoms and complications. Multivariable linear models were fit for symptoms and survey scores. Ordinal regression was used for self-rated health. Backwards selection was run for each model. Alpha of 0.05 and 95% confidence intervals were used.

RESULTS

Of the 162 (275 total; 47.8%) patients who returned surveys (156 female), 130 had carotid or vertebral artery involvement (80.2%). Migraine (p < .001), neck pain (p = .036), and flank pain (p = .025) were associated with decrease in Mental Component scores. Migraine (p = .002) and neck pain (p = .023) were associated with lower Physical Component scores. Patients reporting abdominal pain compared with those without had 4.88 points higher depression. Abdominal pain (p = .031) and pulsatile tinnitus (p = .011) were associated with greater anxiety. Migraine was associated with (p = .002) lower self-rated health. Participants with history of stroke/transient ischemic attack had 2.42 (1.08, 5.46; p = .033) times the odds of poor self-rated health compared with those without stroke/transient ischemic attack.

CONCLUSIONS

Among patients with FMD, presence of pain and history of vascular complications were related to lower quality of life and self-rated health.

Associations between personal protective equipment and nursing staff stress during the COVID-19 pandemic

Aim

This study gives insights into the association between the use of personal protective equipment (PPE), wearing time of masks and stress among frontline nursing staff during the COVID‐19 pandemic.

Background

PPE can have physical consequences like headache and pain, which could result in increased nurse stress levels.

Methods

A total of 2600 nurses participated in this online survey. The questionnaire is based on literature and includes the perceived level of stress scale.

Results

We found no significant association between the use of PPE and stress. Nurses who wore masks for more than 8 h had significant higher stress levels than those who used the masks for a shorter period.

Conclusions

The duration of wearing masks is associated with nurse's stress level. Our findings can help nurses to argue a higher frequency of breaks and a maximum duration of mask usage in their organisations.

Implications for Nursing Management

We recommend that nursing managers implement practical strategies such as a mask break task force. This task force could promote awareness for mask breaks and recommend and allocate rooms or locations such as balconies for mask breaks.

Poor social support and loneliness in chronic headache: Prevalence and effect modifiers

OBJECTIVE

To explore the prevalence of poor social support and loneliness among people with chronic headache, and how these might be effect modifiers in the relationships between chronic headache and stress, medication overuse, and self-rated health.

BACKGROUND

Poor social support and loneliness are consistently linked to worse health outcomes. There are few epidemiologic studies on their effect on headache.

METHODS

The Danish Capital Region Health Survey, a cross-sectional survey, was conducted in 2017. Participants were asked about headache, pain medication use, social support, loneliness, perceived stress, and self-rated health. Data were accessed from sociodemographic registers. Logistic regression analyses were performed to test for effect modification.

RESULTS

The response rate was 52.6% (55,185 respondents) and was representative of the target population. People with chronic headache were more likely to report poor social support and loneliness compared to those without chronic headache (p < 0.0001 for both). Odds ratios for the combination of chronic headache and poor social support were very high for stress (odds ratio 8.1), medication overuse (odds ratio 21.9), and poor self-rated health (odds ratio 10.2) compared to those without chronic headache and with good social support. Those who reported both chronic headache and loneliness had a very high odds ratio for stress (odds ratio 14.4), medication overuse (odds ratio 20.1), and poor self-rated health (odds ratio 15.9) compared to those without chronic headache and low loneliness score. When adjusted for sociodemographic factors, poor social support and loneliness were not significant effect modifiers in almost all these associations. Loneliness was a significant effect modifier in the association between chronic headache and medication overuse, but exerted greater effect among those who did not report they were lonely.

CONCLUSION

Poor social support and loneliness were prevalent among people with chronic headache. The combination of chronic headache and poor social support or loneliness showed higher odds ratios for stress, medication overuse, and poor self-rated health compared to those with good social support and low loneliness scores. The effect of loneliness in the relationship between chronic headache and medication overuse warrants further study.

Estimation of the Impact of Migraine on Self-rated Health: A Cross-sectional Study in Slovenia

Aim

With the aim of providing a foundation for evidence-based public health actions, as well as the more individualised clinical treatment of migraine in Slovenia, the objective of our study was to assess the association between poor self-rated health (PSRH) and migraine, adjusted for selected comorbidity and socioeconomic factors.

Methods

The survey, conducted between August and December 2014, involved included 6,262 adults aged 15 years and over. Binary logistic regression was used in univariate as well as multivariate analysis. Three multivariate models were defined: MODEL 1 (migraine and comorbidities related to the physical dimension of health); MODEL 2 (comorbidities related to the mental dimension of health); MODEL 3 (demographic and socioeconomic factors).

Results

In univariate as well as all three multivariate models, the odds of PSRH were statistically significantly higher in migraine sufferers in comparison to non-sufferers (univariate model: ORmigraine=yes vs. migraine=no=2.22 (p<0.001); MODEL 1: ORmigraine=yes vs. migraine=no=2.27 (p<0.001); MODEL 2: ORmigraine=yes vs. migraine=no=1.51 (p=0.002); MODEL 3: ORmigraine=yes vs. migraine=no=1.56 (p=0.001)).

Conclusion

Migraine is an important PSRH-related factor. Comorbidities related to the physical dimension of health do not reduce the power of association between migraine and PRSH, while comorbidities related to the mental dimension reduce the power of association of migraine and other health conditions. The power of the association between migraine and PRSH is also independent of demographic/socioeconomic factors. We can also conclude that migraine seems to be a phenomenon that is in a bi-directional relationship with mental states (thus having an impact on PSRH) and is itself a stressor.

Involvement of cervical disability in migraine: a literature review

Background

The trigeminal nerve theory has been proposed as a pathophysiological mechanism of migraine; however, its association with the triggers of migraine remains unclear. Cervical disability such as neck pain and restricted cervical rotation, have been associated with not only cervicogenic headaches but also migraine. The presence of cervical disability could worsen of the migraine, and also the response to pharmacologic treatment may be reduced. The aim in this review is to highlight the involvement of cervical disability in migraine, considering contributing factors.

Findings

In recent years, evidence of neck pain complaints in migraine has been increasing. In addition, there is some recent evidence of cervical musculoskeletal impairments in migraine, as detected by physical assessment. However, the main question of whether neck pain or an associated cervical disability can act as an initial factor leading to migraine attacks still remains. Daily life imposes heavy loads on cervical structures (i.e. muscles, joints and ligaments), for instance, in the forward head position. The repetitive nociceptive stimulation initiating those cervical skeletal muscle positions may amplify the susceptibility to central migraine and contribute to chronicity via the trigeminal cervical complex.

Conclusion

Further studies are needed to explain the association between cervical disability as a source of pain and the development of migraine. However, evidence suggests that cervical disability needs to be considered in the prevention and treatment of migraine.

The Role of Positive Health Behaviors in the Relationship Between Early Life Stress and Migraine

BACKGROUND

The use of diet and physical activity in alleviating the burden of migraine is unclear, therefore, more scientific study on the role of positive health behaviors in migraine management is needed.

OBJECTIVE

To explore the potential moderating influence of positive health behaviors on the early life stress-migraine relationship in a sample of the Canadian adult population.

METHODS

This study used data from the 2011-2012 Canadian Community Health Survey - Annual Component, a National cross-sectional survey. Adults ≥18 years of age residing in British Columbia were surveyed about stressors experienced as children/teenagers (eg, parental divorce and substance abuse exposure). Migraine was self-report of health-professional diagnosis. Positive health behaviors were measured using an index of transportation and leisure time physical activity, and self-reported frequency of vegetable and fruit consumption. Population survey weights were employed throughout and analytic models were adjusted for known confounders (n_unweighted  = 11,910).

RESULTS

The weighted prevalence of migraine was 9.7% (95% CI: 9.1%, 10.2%). Odds of migraine increased as number of stressors increased: 1 early life stressor (OR = 1.18, 95% CI: 1.01, 1.39), and ≥ 2 early life stressors (OR = 1.51, 95% CI: 1.29, 1.76), compared to no stress. There was evidence of effect modification by physical activity (χ² (4) = 16.02, P < .001). The association between 1 early life stressor and migraine was lower for those who were physically active (moderately active: OR = 1.20, 95% CI: 0.90, 1.61; active: OR = 0.82, 95% CI: 0.61, 1.11). This difference was not apparent for those who experienced 2 or more early life stressors (moderately active: OR = 1.67, 95% CI: 1.28, 2.17; active: OR = 1.55, 95% CI: 1.21, 1.99). Across all levels of early life stress, physically active respondents had lower odds of migraine than moderately active respondents. There was no effect modification by vegetable, fruit, and total fruit/vegetable consumption.

CONCLUSIONS

Stressors experienced early in life are associated with migraine, and physical activity may ameliorate this relationship, particularly for those with exposure to a minimal level of early life stress. A higher dose of physical activity may yield greater benefit than a less intensive dose (ie, moderate activity level). However, the cross-sectional nature of this study precludes us from inferring causality, and future investigation requires prospectively collected data.

Impact of Cervical Sensory Feedback for Forward Head Posture on Headache Severity and Physiological Factors in Patients with Tension-type Headache: A Randomized, Single-Blind, Controlled Trial

BACKGROUND Tension-type headache (TTH) decreases the ability to concentrate and function during daily activities in affected patients. As most patients with TTH exhibit forward head posture (FHP). Various interventions have been proposed to resolve TTH. However, research regarding the efficacy of these interventions remains lacking. The present study aimed to investigate the association between FHP and TTH, and to evaluate the efficacy of various intervention methods on headache symptoms and other clinical variables in patients with TTH induced by FHP. MATERIAL AND METHODS Participants were randomly allocated to 3 groups: biofeedback (BF, n₁=21), manual therapy (MT, n₂=20) and, stretching (ST, n₃=21). Interventions were conducted 3 times per week for 4 weeks. Craniovertebral angle (CVA), electroencephalographic findings for attention, stress, and pressure-pain threshold (PPT), headache on activities of daily living (Henry Ford Headache Disability Inventory, HDI), and quality of life (QoL) assessments were obtained pre-intervention, post-intervention, and at the 2-week follow-up. RESULTS The correlation between CVA and HDI after intervention (R²=0.324, P<0.001), and at 2-week follow-up (R²=0.115, P<0.01) are significant. BF was associated with significant improvements in CVA (F₂,₅₉=3.393, P<0.001, η^2/P=0.130), attention (F₂,₅₉=5.186, P<0.01, η^2/P=0.150), stress [skin temperature (F₂,₅₉=6.005, P<0.001, η^2/P=0.169) and skin conductance (F₂,₅₉=4.900, P<0.01, η^2/P=0.142)], PPT (F₂,₅₉=5.050, P<0.01, η^2/P=0.146), HDI (F₂,₅₉=3.303, P<0.01, η^2/P=0.101), and QoL (F₂,₅₉=3.409, P<0.05, η^2/P=0.104). CONCLUSIONS Our findings indicate that BF was more effective than MT and ST in the treatment of TTH due to FHP. Such findings highlight the need to develop and promote a controlled exercise program to facilitate a return to normal daily activities in patients with TTH due to FHP.

Temporomandibular disorders, pain in the neck and shoulder area, and headache among musicians

Background

Uncertainties still exist about the role of playing musical instruments on the report of musculoskeletal complaints and headache.

Objectives

To evaluate the prevalence of and risk indicators for symptoms of temporomandibular disorders, pain in the neck or shoulder, and headache among musicians.

Methods

A questionnaire was distributed among 50 Dutch music ensembles.

Results

The questionnaire was completed by 1470 musicians (response rate 77.0%). Of these, 371 musicians were categorised as woodwind players, 300 as brass players, 276 as upper strings players, 306 as vocalists and 208 as controls; nine musicians had not noted their main instrument. The mean age was 41.6 years (standard deviation [SD] 17.2), and 46.5% were male. Irrespective of instrumentalist group, 18.3% of the musicians reported TMD pain, 52.5% reported pain in the neck and shoulder area, and 42.5% reported headache. Of the functional complaints, 18.3% of the musicians reported TMJ sounds, whereas a jaw lock or catch on opening or on closing was reported by 7.1% and 2.4%, respectively. TMD pain was associated with playing a woodwind instrument, whereas pain in the neck and shoulder was associated with playing the violin or viola. For each complaint, oral behaviours were found as risk indicator, supplemented by specific risk indicators for the various complaints.

Conclusions

The current finding that pain‐related symptoms varied widely between instrumentalist groups seems to reflect the impact of different instrument playing techniques. Playing a musical instrument appears not the primary aetiologic factor in precipitating a functional temporomandibular joint problem.

Emerging evidence of occipital nerve compression in unremitting head and neck pain

Unremitting head and neck pain (UHNP) is a commonly encountered phenomenon in Headache Medicine and may be seen in the setting of many well-defined headache types. The prevalence of UHNP is not clear, and establishing the presence of UHNP may require careful questioning at repeated patient visits. The cause of UHNP in some patients may be compression of the lesser and greater occipital nerves by the posterior cervical muscles and their fascial attachments at the occipital ridge with subsequent local perineural inflammation. The resulting pain is typically in the sub-occipital and occipital location, and, via anatomic connections between extracranial and intracranial nerves, may radiate frontally to trigeminal-innervated areas of the head. Migraine-like features of photophobia and nausea may occur with frontal radiation. Occipital allodynia is common, as is spasm of the cervical muscles. Patients with UHNP may comprise a subgroup of Chronic Migraine, as well as of Chronic Tension-Type Headache, New Daily Persistent Headache and Cervicogenic Headache. Centrally acting membrane-stabilizing agents, which are often ineffective for CM, are similarly generally ineffective for UHNP. Extracranially-directed treatments such as occipital nerve blocks, cervical trigger point injections, botulinum toxin and monoclonal antibodies directed at calcitonin gene related peptide, which act primarily in the periphery, may provide more substantial relief for UHNP; additionally, decompression of the occipital nerves from muscular and fascial compression is effective for some patients, and may result in enduring pain relief. Further study is needed to determine the prevalence of UHNP, and to understand the role of occipital nerve compression in UHNP and of occipital nerve decompression surgery in chronic head and neck pain.

Self-Rated Health and Inflammation: A Test of Depression and Sleep Quality as Mediators

OBJECTIVE

Despite its simplicity, single-item measures of self-rated health have been associated with mortality independent of objective health conditions. However, little is known about the mechanisms potentially responsible for such associations. This study tested the association between self-rated heath and inflammatory markers as biological pathways, and whether sleep quality and/or depression statistically mediated such links.

METHOD

Eighty-six heterosexual married couples completed a standard measure of self-rated health, the Center of Epidemiological Studies-Depression Scale, and the Pittsburgh Sleep Quality Index. Participants also had blood drawn for determination of plasma levels of interleukin 6 and high-sensitivity C-reactive protein. The Monte Carlo method was used to construct confidence intervals for mediation analyses.

RESULTS

Results indicated that poor self-rated health was associated with higher CRP levels (B = .31, SE = .14, p = .028). Importantly, the Monte Carlo mediational analyses showed that these results were statistically mediated by sleep quality (aXb = 0.10, 95% confidence interval = 0.003 to 0.217) but not depressive symptoms (aXb = 0.03, 95% confidence interval = -0.03 to 0.10).

CONCLUSIONS

These results highlight the biological and behavioral mechanisms potentially linking self-rated health to longer-term health outcomes. Such work can inform basic theory in the area as well as intervention approaches that target such pathways.

Self-reported sinus headaches are associated with neck pain and cervical musculoskeletal dysfunction: a preliminary observational case control study

Objectives: Headaches can be associated with rhinosinusitis and may present a diagnostic challenge because of symptomatic overlap with other recurring headaches. Neck pain has received extensive attention in migraine, tension-type and cervicogenic headache but not as a comorbid feature of headache in those with rhinosinusitis. This study investigated the occurrence of neck pain and cervical musculoskeletal dysfunction in individuals with self-reported sinus headaches (SRSH).

Methods: Participants with and without SRSH attended a single data collection session. Participants completed the Headache Impact Test (HIT)-6 and the Sino-Nasal Outcome Test (SNOT)-22. Cervical range of motion (ROM), segmental examination, muscle endurance and pressure-pain threshold (PPT) were measured .

Results: Participants included 31 with SRSH (77.4% female; age 43.7 (9.9) years) and 30 without headache. Average symptom duration was 89.7 (±85.6) months. Mean SNOT-22 and HIT-6 scores were 36.2 (15.3) and 56.7 (7.1), respectively. In the SRSH group, 83.9% (n = 26) reported neck pain. There was a significant difference between groups for cervical sagittal (14.3° [5.3°, 23.3°], p = 0.002) and transverse plane ROM (21.5° [12.4°, 30.6°], p < 0.001), but no difference in frontal plane motion (p = 0.017). There were significant between groups difference in neck flexor endurance (19.5 s [10.1 s, 28.9 s], <0.001), segmental dysfunction O-C4 (p < 0.001) but not in PPT (p = 0.04).

Discussion: Neck pain and cervical musculoskeletal dysfunction are common among persons with SRSH and may be a comorbid feature or contributing factor to headaches attributed to rhinosinusitis. Further research is needed to understand these associations.

Mediterranean Diet and Motivation in Sport: A Comparative Study Between University Students from Spain and Romania

BACKGROUND

The Mediterranean Diet (MD) is one of the healthiest dietary models worldwide, being an essential mean of preventing pathologies along with the practice of physical activity. Through a comparative study carried out across different countries, it has been demonstrated how this type of habits vary depending on the geographical context. The aim of this research was to evaluate the adherence to MD and its relationships with motivational climate in sport on a sample of university students from Spain and Romania; Methods: A cross-sectional study was conducted on a sample of university students [specialization: Physical Education (n = 605; 20.71 ± 2.42 years old)], using as main instruments the Mediterranean Diet Quality Index (KIDMED) for students and adolescents and the Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2); Results: It was shown that students from Spain had a high adherence to the MD (6.65 ± 2.63 vs. 5.06 ± 1.31). Spanish university students got higher scores in task-oriented motivational climate (4.03 ± 0.62 vs. 3.11 ± 0.55) while ego-oriented climate was higher in university students from Romania (3.24 ± 0.54 vs. 2.07 ± 0.75). Finally, it was observed that the task-oriented motivational climate was related to a lower adherence to MD in Spanish students (4.49 ± 0.37 vs. 3.98 ± 0.62). In contrast, in Romanian youth, a medium adherence to the MD was associated with higher scores for the ego-oriented motivational climate (3.27 ± 0.53 vs. 3.00 ± 0.54); Conclusions: As main conclusions, it was shown that the students from Spain had a high adherence to the MD. In addition, it has been demonstrated that ego-oriented climates are linked to a better adherence to MD, especially due to the importance of following a proper diet in sport contexts, as demonstrated by young Romanians.

Has aerobic exercise effect on pain perception in persons with migraine and coexisting tension-type headache and neck pain? A randomized, controlled, clinical trial

BACKGROUND

A large subset of persons with migraine suffers from coexisting tension-type headache and neck pain which may adversely affect the prognosis of migraine. Aerobic exercise has been shown to decrease migraine burden in these persons. Therefore, the aim of this study was to investigate whether the effect of aerobic exercise in persons with migraine and coexisting tension-type headache and neck pain can be explained by changes in pain perception.

METHOD

Seventy consecutively recruited persons with migraine and coexisting tension-type headache and neck pain were randomized into exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 min, three times/week for 3 months. Controls continued their usual daily activities. Pericranial tenderness, pain thresholds, supra-thresholds and temporal summation were assessed at baseline, after treatment and at follow-up (6 months from baseline).

RESULTS

Fifty-two persons with migraine and coexisting tension-type headache and neck pain completed the study. Aerobic exercise did not induce consistent changes in nociceptive pathways measured by pericranial tenderness, pressure pain thresholds and sensitivity to electrical stimulation.

CONCLUSION

The effect of aerobic exercise cannot be explained by measurable effects on the pain modulation system. Thus, the positive effect on migraine burden may rather be explained by positive alteration of avoidance behaviour. Aerobic exercise can be recommended as a safe and inexpensive migraine treatment strategy.

SIGNIFICANCE

This study adds further knowledge about the positive effect of aerobic exercise for persons with migraine and coexisting tension-type headache and neck pain. This effect cannot be measured by changes in pain modulation, but may rather be explained by positive alteration of avoidance behaviour.

The effects of aerobic exercise for persons with migraine and co-existing tension-type headache and neck pain. A randomized, controlled, clinical trial

Aim To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activities. Pain frequency, intensity, and duration; physical fitness, level of physical activity, well-being and ability to engage in daily activities were assessed at baseline, after treatment and at follow-up. Results Fifty-two persons completed the study. Significant between-group improvements for the exercise group were found for physical fitness, level of physical activity, migraine burden and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Within the exercise group, significant reduction was found for migraine frequency, pain intensity and duration, neck pain intensity, and burden of migraine; an increase in physical fitness and well-being. Conclusions Exercise significantly reduced the burden of migraine and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Exercise also reduced migraine frequency, pain intensity and duration, although this was not significant compared to controls. These results emphasize the importance of regular aerobic exercise for reduction of migraine burden.
