Tension-type Headache (tension-type + headache)
Kinds of Tension-type Headache Selected AbstractsMyofascial Trigger Points, Neck Mobility, and Forward Head Posture in Episodic Tension-Type HeadacheHEADACHE, Issue 5 2007César Fernández-de-las-Peñas PT Objective.,To assess the differences in the presence of trigger points (TrPs) in head and neck muscles, forward head posture (FHP) and neck mobility between episodic tension-type headache (ETTH) subjects and healthy controls. In addition, we assess the relationship between these muscle TrPs, FHP, neck mobility, and several clinical variables concerning the intensity and the temporal profile of headache. Background.,TTH is a headache in which musculoskeletal disorders of the craniocervical region might play an important role in its pathogenesis. Design.,A blinded, controlled pilot study. Methods.,Fifteen ETTH subjects and 15 matched controls without headache were studied. TrPs in both upper trapezius, both sternocleidomastoids, and both temporalis muscles were identified according to Simons and Gerwin diagnostic criteria (tenderness in a hypersensible spot within a palpable taut band, local twitch response elicited by snapping palpation, and elicited referred pain with palpation). Side-view pictures of each subject were taken in both sitting and standing positions, in order to assess FHP by measuring the craniovertebral angle. A cervical goniometer was employed to measure neck mobility. All measures were taken by a blinded assessor. A headache diary was kept for 4 weeks in order to assess headache intensity, frequency, and duration. Results.,The mean number of TrPs for each ETTH subject was 3.7 (SD: 1.3), of which 1.9 (SD: 0.9) were active, and 1.8 (SD: 0.9) were latent. Control subjects only had latent TrPs (mean: 1.5; SD: 1). TrP occurrence between the 2 groups was significantly different for active TrPs (P < .001), but not for latent TrPs (P > .05). Differences in the distribution of TrPs were significant for the right upper trapezius muscles (P= .04), the left sternocleidomastoid (P= .03), and both temporalis muscles (P < .001). Within the ETTH group, headache intensity, frequency, and duration outcomes did not differ depending on TrP activity, whether the TrP was active or latent. The craniovertebral angle was smaller, ie, there was a greater FHP, in ETTH patients than in healthy controls for both sitting and standing positions (P < .05). ETTH subjects with active TrPs in the analyzed muscles had a greater FHP than those with latent TrPs in both sitting and standing positions, though differences were only significant for certain muscles. Finally, ETTH patients also showed lesser neck mobility than healthy controls in the total range of motion as well as in half-cycles (except for cervical extension), although neck mobility did not seem to influence headache parameters. Conclusions.,Active TrPs in the upper trapezius, sternocleidomastoid, and temporalis muscles were more common in ETTH subjects than in healthy controls, although TrP activity was not related to any clinical variable concerning the intensity and the temporal profile of headache. ETTH patients showed greater FHP and lesser neck mobility than healthy controls, although both disorders were not correlated with headache parameters.

CTTH subjects with active TrPs had a greater FHP than those with latent TrPs, though this difference was not significant. Conclusions.,Suboccipital active TrPs and FHP were associated with CTTH. CCTH subjects with active TrPs reported a greater headache intensity and frequency than those with latent TrPs. The degree of FHP correlated positively with headache duration, headache frequency, and the presence of suboccipital active TrPs. [source] Characteristic and Overlapping Features of Migraine and Tension-Type HeadacheHEADACHE, Issue 3 2006Dilsad Turkdogan MD Objective.,This epidemiological survey was conducted to investigate comprehensive characteristic and overlapping features of migraine and tension-type headache (TTH) disorders classified based on International Classification of Headache Disorders-II. Methods.,The stratified cohort of this study was composed of 2504 schoolchildren aged 10 to 17 years. A 38-item questionnaire inquiring all characteristic features of primary headache syndromes mandatory for classification was applied to selected 483 children with recurrent headache in the last 6 months. Results.,Migraine was diagnosed in 227 (47.0%) of 483 children and TTH in 154 (31.9%). Out of 125 children with definite migraine, 73 (58.4%) reported tension-type symptoms and 94 (68.1%) of 138 children with definite TTH reported migraine-type symptoms. Pressing pain (21%) and lack of aggravation of pain by physical activity (34%) were the major tension-type features in patients with migraine. Throbbing quality (43%) and aggravation by physical activity (30%) determined the main migraine-type features in patients with TTH. Conclusion.,The frequent co-occurrence of migraine and TTH symptoms suggests the presence of a common pathogenesis. [source] Referred Pain Elicited by Manual Exploration of the Lateral Rectus Muscle in Chronic Tension-Type HeadachePAIN MEDICINE, Issue 1 2009César Fernández-de-las-Peñas PT ABSTRACT Objective., To analyze the presence of referred pain elicited by manual examination of the lateral rectus muscle in patients with chronic tension-type headache (CTTH). Design., A case-control blinded study. Setting., It has been found previously that the manual examination of the superior oblique muscle can elicit referred pain to the head in some patients with migraine or tension-type headache. However, a referred pain from other extraocular muscles has not been investigated. Methods., Fifteen patients with CTTH and 15 healthy subjects without headache history were included. A blinded assessor performed a manual examination focused on the search for myofascial trigger points (TrPs) in the right and left lateral rectus muscles. TrP diagnosis was made when there was referred pain evoked by maintained pressure on the lateral corner of the orbit (anatomical projection of the lateral rectus muscle) for 20 seconds, and increased referred pain while the subject maintained a medial gaze on the corresponding side (active stretching of the muscle) for 15 seconds. On each side, a 10-point numerical pain rate scale was used to assess the intensity of referred pain at both stages of the examination. Results., Ten patients with CTTH (66.6%) had referred pain that satisfied TrPs diagnostic criteria, while only one healthy control (0.07%) reported referred pain upon the examination of the lateral rectus muscles (P < 0.001). The elicited referred pain was perceived as a deep ache located at the supraorbital region or the homolateral forehead. Pain was evoked on both sides in all subjects with TrPs, with no difference in pain intensity between the right and the left. The average pain intensity was significantly greater in the patient group (P < 0.001). All CTTH patients with referred pain recognized it as the frontal pain that they usually experienced during their headache attacks, which was consistent with active TrPs. Conclusion., In some patients with CTTH, the manual examination of lateral rectus muscle TrPs elicits a referred pain that extends to the supraorbital region or the homolateral forehead. Nociceptive inputs from the extraocular muscles may sustain the activation of trigeminal neuron, thus sensitizing central pain pathways and exacerbating headache. [source] Electroacupuncture for Tension-type Headache on Distal Acupoints Only: A Randomized, Controlled, Crossover TrialHEADACHE, Issue 4 2004C. C. L. Xue PhD Objective.,To investigate the efficacy of electroacupuncture, applied to distal acupoints only, for tension-type headache. Background.,Electroacupuncture is commonly used for tension-type headache, but when applied to distal acupoints only, evidence of its efficacy is lacking. Design.,A randomized, single-blinded, sham-controlled, crossover clinical trial. Methods.,The trial had 5 stages: baseline (2 weeks), phases I and II (each 4 weeks), washout period (2 weeks), and follow-up (3 months after phase II). Forty patients were randomly assigned to either group A or group B. Group A received real electroacupuncture during phase I, then sham electroacupuncture in phase II. Group B received the treatments in reverse order. Outcome measures were headache frequency and duration, pain intensity using a visual analog scale, mechanical pain threshold, headache disability, and sickness impact. Data were analyzed by univariate 2-way analysis of variance. Results.,Thirty-seven patients completed the trial. There were no significant differences between the 2 groups at baseline. At the end of phase I, group A, but not group B, demonstrated significant improvement in mean (standard error of the mean [SEM]) headache frequency (3.0 per month [0.3] versus 12.0 per month [1.7]), duration (13.3 hours [3.5] versus 32.0 hours [6.2]), pain intensity (32.8 mm [4.1] versus 47.5 mm [2.7]), pain threshold (right side, 2.9 kg/second [0.1] versus 0.9 kg/second [0.1]; left side, 2.4 kg/second [0.1] versus 1.1 kg/second [0.1]), headache disability score (6.0 [1.0] versus 16.3 [1.6]), and sickness impact score (288.7 [48.0] versus 687.1 [77.2]). For each parameter, significant differences also were demonstrated for both groups between baseline and phase II, and baseline and follow-up. There were no significant differences between the groups at the end of follow-up (P > .05). Conclusion.,Electroacupuncture to distal points alone is effective for short-term symptomatic relief of tension-type headache.

The degree of FHP correlated positively with headache duration, headache frequency, and the presence of suboccipital active TrPs. [source] Chronic post-traumatic headache after head injuryin children and adolescentsDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 6 2008Charlotte Kirk MBChB MRCPCH BSc This was a prospective, observational study of children aged 3 to 15 years admitted to hospital with head injury (HI). Demographic data and information on the nature of the HI, and history of premorbid headache were collected. A structured telephone questionnaire was used to interview parents and children 2 months after injury and at 4-monthly intervals for up to 3 years, if headache was reported. One hundred and ninety children were admitted with HI. Data were available on 117 children (81 males, 36 females; mean age 8y 5mo [SD 3y 1mo]). HI was minor in 93 patients and significant in the rest. Minor HI was defined as a closed injury, no loss of consciousness, and a Glasgow Coma Score (GCS) of 13 to 15. Significant HI was associated with loss of consciousness for >30 minutes, GCS of <13, and post-traumatic amnesia for >48 hours. Eight children (five males, three females; mean age 10y 7mo [SD 2y]) reported chronic post-traumatic headache (CPTH). Five children had episodic tension-type headache and three had migraine with or without aura. Headache resolved over 3 to 27 months in all except one child who was lost to follow-up. Premorbid headache in three children transformed in frequency and type following HI. These patients were excluded from the study. CPTH is common after minor and significant HI. It has the clinical features of tension-type headache and migraine and has a good prognosis. [source] Pericranial injection of botulinum toxin type A (Dysport®) for tension-type headache , A multicentre, double-blind, randomized, placebo-controlled studyEUROPEAN JOURNAL OF NEUROLOGY, Issue 3 2008A. Straube Increasingly, botulinum type A toxin is used to influence pathologically increased muscle activity in conditions such as dystonia and spasticity. Studies have also assessed its efficacy in tension-type headache, where muscle tenderness may be increased. We undertook a prospective, multicentre, randomized, double-blind, placebo-controlled trial. Patients received injections of Dysport® (total dose of 420 or 210 units) or saline placebo in 18 sites on the head and neck. Of 125 patients treated, 118 were included in the intention-to-treat dataset. No significant differences between each verum group and placebo were seen for the primary efficacy parameter , change in the number of headache-free days at 4,8 weeks after injection compared with 4 weeks before injection. The groups receiving 420 or 210 units of Dysport experienced 2.60 and 2.87 more headache-free days respectively, compared with 1.93 more headache-free days for the placebo group (P = 0.66 versus 420 units; P = 0.52 versus 210 units). Treatment with 420 units of Dysport was associated with significant improvements compared with placebo for two secondary efficacy parameters: mean change in headache duration from baseline to weeks 8,12 (P < 0.05) and improved global physician and patient assessment scores (P < 0.05). Further studies should address the possible value of multiple injections with extended observation periods, dose optimization, and whether duration of headache history and number of previous treatments are predictors of patient response. [source] Combination of low-dose mirtazapine and ibuprofen for prophylaxis of chronic tension-type headacheEUROPEAN JOURNAL OF NEUROLOGY, Issue 2 2007L. Bendtsen Chronic headaches are difficult to treat and represent the biggest challenge in headache centres. Mirtazapine has a prophylactic and ibuprofen an acute effect in tension-type headache. Combination therapy may increase efficacy and lower side effects. We aimed to evaluate the prophylactic effect of a combination of low-dose mirtazapine and ibuprofen in chronic tension-type headache. Ninety-three patients were included in the double-blind, placebo-controlled, parallel trial. Following a 4-week run-in period they were randomized to four groups for treatment with a combination of mirtazapine 4.5 mg and ibuprofen 400 mg, placebo, mirtazapine 4.5 mg or ibuprofen 400 mg daily for 8 weeks. Eighty-four patients completed the study. The primary efficacy parameter, change in area under the headache curve from run-in to the last 4 weeks of treatment, did not differ between combination therapy (190) and placebo (219), P = 0.85. Explanatory analyses revealed worsening of headache already in the third week of treatment with ibuprofen alone. In conclusion, the combination of low-dose mirtazapine and ibuprofen is not effective for the treatment of chronic tension-type headache. Moreover, the study suggests that daily intake of ibuprofen worsens headache already after few weeks in chronic tension-type headache. [source] Induction of prolonged tenderness in patients with tension-type headache by means of a new experimental model of myofascial painEUROPEAN JOURNAL OF NEUROLOGY, Issue 3 2003H. Mørk Tenderness is the most prominent abnormal finding in patients with tension-type headache (TTH). Recently we developed a model of myofascial tenderness using intramuscular infusion of a combination of bradykinin, serotonin, histamine and prostaglandin E2. We aimed to examine tenderness after this combination in patients with episodic TTH (ETTH). Fifteen patients and 15 healthy controls completed the study. Participants received the combination into the non-dominant trapezius muscle in a randomized, double-blinded and placebo-controlled design. Local tenderness and stimulus,response functions, mechanical pain thresholds (PPDT) in the temporal region and on the finger, and total tenderness score (TTS) were recorded. A local, prolonged, and mild to moderate tenderness was reported both in patients (P = 0.001) and in controls (P = 0.001) after the combination compared with the placebo. The response to the combination tended to be increased in patients. The stimulus,response function was leftward shifted after the combination, compared with baseline in both groups. No changes in PPDT or TTS were found after the infusions, whereas baseline PPDTs were decreased in ETTH compared with controls (PPDTfinger: P = 0.033; PPDTtemporal: P = 0.015). Intramuscular infusion of a combination of endogenous substances induced prolonged tenderness in both patients with episodic TTH and healthy subjects. The present results suggest an increased excitability of peripheral muscle afferents in TTH. [source] Research Submission: Chronic Headache and Comorbibities: A Two-Phase, Population-Based, Cross-Sectional StudyHEADACHE, Issue 8 2010Ariovaldo Da Silva Jr MD Background., Studies using resources of a public family health program to estimate the prevalence of chronic daily headaches (CDH) are lacking. Objectives., To estimate the 1-year prevalence of CDH, as well as the presence of associated psychiatric and temporomandibular disorders (TMD) comorbidities, on the entire population of a city representative of the rural area of Brazil. Methods., This was a cross-sectional, population-based, 2-phase study. In the first phase, health agents interviewed all individuals older than 10 years, in a rural area of Brazil. In the second stage, all individuals who reported headaches on 4 or more days per week were then evaluated by a multidisciplinary team. CDH were classified according to the second edition of the International Classification of Headache Disorders (ICHD-2). Medication overuse headache was diagnosed, as per the ICHD-2, after detoxification trials. Psychiatric comorbidities and TMD were diagnosed based on the DSM-IV and on the Research Diagnostic Criteria for Temporomandibular Disorders criteria, respectively. Results., A total of 1631 subjects participated in the direct interviews. Of them, 57 (3.6%) had CDH. Chronic migraine was the most common of the CDH (21, 36.8%). Chronic tension-type headache (10, 17.5%), medication overuse headache (13, 22.8%) and probable medication overuse headache (10, 17.5%) were also common. Psychiatric disorders were observed in 38 (67.3%) of the CDH subjects. TMD were seen in 33 (58.1)% of them. Conclusions., The prevalence of CDH in the rural area of Brazil is similar to what has been reported in previous studies. A significant proportion of them have psychiatric comorbidities and/or TMD. In this sample, comorbidities were as frequent as reported in convenience samples from tertiary headache centers.

[source] Application of the ICHD-II Criteria to the Diagnosis of Primary Chronic Headaches Via a Computerized Structured RecordHEADACHE, Issue 1 2007Paola Sarchielli MD Background.,The authors recently developed a software program designed to analyze clinical data from patients affected by primary headache. The program is based exclusively on the International Classification of Headache Disorders 2nd edition (ICHD-II) criteria. This software examines all the diagnoses of primary headaches on the basis of the variables needed to fulfill these mandatory criteria. Methods.,We tested the software, Primary Headaches Analyser 1.0 INT (PHA), by entering and analyzing clinical data from 200 consecutive patients affected by primary chronic headaches and evaluating the corresponding output diagnoses. Results.,The diagnosis of chronic migraine (1.5.1) was obtained in 68 cases (34 %) and that of probable chronic migraine (1.6.5) plus probable medication-overuse headache (8.2.8) in 46 (23%). Chronic tension-type headache (2.3) and probable chronic tension-type headache (2.4.3) plus probable medication-overuse headache (8.2.8) were diagnosed in 24 (12%) and 2 (1%) patients, respectively. Moreover, 4 and 12 patients, respectively, received both the diagnosis of chronic migraine (1.5.1) plus chronic tension-type headache (2.3) and of probable migraine (1.6.1) without aura plus chronic tension-type headache (2.3). In the remaining 44 cases (22%), none of the chronic primary headaches disorders defined by ICHD-II received an output diagnosis from the program. This was due mainly to the fact that the criteria fulfilled were insufficient for the diagnoses of migraine without (1.1) aura plus chronic migraine or, more infrequently, chronic tension-type headache. Conclusions.,Our software program permitted diagnoses of chronic migraine, chronic tension-type or their probable forms (with or without MOH) in 78% of 200 patients with headache 15 or more days per month. In the remaining cases the inability to provide a specific diagnosis may be explained in part by the fact that the criteria for both diagnoses are too stringent and do not accurately reflect variations of the headache pattern in these chronic forms. [source] Implicit Associations in Tension-Type Headaches: A Cognitive Analysis Based on Stress Reactivity ProcessesHEADACHE, Issue 8 2006Jennifer F. Armstrong BS Objective.,To determine whether tension-type headache (TTH) patients display stronger associations between negative events and headache-related information than headache-free controls. Background.,Generally, stress/diathesis models are common in clinical research and in the context of TTHs specifically. Data involving stress reactivity processes are compatible with such models. However, it would be of interest to tap the associative cognitive processes that likely mediate such relations. Methods.,In the present study, we selectively recruited individuals who do (n = 19) and do not (n = 19) suffer from episodic TTHs. We examined implicit associations between negative evaluations and headache-related information through the use of an implicit association test. Results.,As hypothesized, TTH patients displayed associations between negative evaluations and headache-related information, whereas the control group did not. Conclusions.,These data provide initial support for a plausible cognitive model for the occurrence of TTHs among predisposed individuals. [source] Not Tonight, I Have a Headache?HEADACHE, Issue 6 2006Timothy T. Houle PhD Objective.,The present study examined the relationship between the diagnosis of migraine and self-reported sexual desire. Background.,There is evidence for a complex relationship between sexual activity and headache, particularly migraine. The current headache diagnostic criteria even distinguish between several types of primary headaches associated with sexual activity. Methods.,Members of the community or students at the Illinois Institute of Technology (N = 68) were administered the Brief Headache Diagnostic Interview and the Sexual Desire Inventory (SDI). Based on the revised diagnostic criteria established by the International Headache Society (ICHD-II), participants were placed in 1 of the 2 headache diagnostic groups: migraine (n = 23) or tension-type (n = 36). Results.,Migraine subjects reported higher SDI scores, and rated their own perceived level of desire higher than those suffering from tension-type headache. The presence of the symptom "headache aggravated by routine physical activity" significantly predicted an elevated SDI score. Conclusions.,Migraine headaches and sexual desire both appear to be at least partially modulated by serotonin (5-HT). The metabolism of 5-HT has been shown to covary with the onset of a migraine attack, and migraineurs appear to have chronically low systemic 5-HT. As sexual desire also has been linked to serotonin levels, the results are consistent with the hypothesis that migraine and sexual desire both may be modulated by similar serotonergic phenomena.

Xue PhD Objective.,To investigate the efficacy of electroacupuncture, applied to distal acupoints only, for tension-type headache. Background.,Electroacupuncture is commonly used for tension-type headache, but when applied to distal acupoints only, evidence of its efficacy is lacking. Design.,A randomized, single-blinded, sham-controlled, crossover clinical trial. Methods.,The trial had 5 stages: baseline (2 weeks), phases I and II (each 4 weeks), washout period (2 weeks), and follow-up (3 months after phase II). Forty patients were randomly assigned to either group A or group B. Group A received real electroacupuncture during phase I, then sham electroacupuncture in phase II. Group B received the treatments in reverse order. Outcome measures were headache frequency and duration, pain intensity using a visual analog scale, mechanical pain threshold, headache disability, and sickness impact. Data were analyzed by univariate 2-way analysis of variance. Results.,Thirty-seven patients completed the trial. There were no significant differences between the 2 groups at baseline. At the end of phase I, group A, but not group B, demonstrated significant improvement in mean (standard error of the mean [SEM]) headache frequency (3.0 per month [0.3] versus 12.0 per month [1.7]), duration (13.3 hours [3.5] versus 32.0 hours [6.2]), pain intensity (32.8 mm [4.1] versus 47.5 mm [2.7]), pain threshold (right side, 2.9 kg/second [0.1] versus 0.9 kg/second [0.1]; left side, 2.4 kg/second [0.1] versus 1.1 kg/second [0.1]), headache disability score (6.0 [1.0] versus 16.3 [1.6]), and sickness impact score (288.7 [48.0] versus 687.1 [77.2]). For each parameter, significant differences also were demonstrated for both groups between baseline and phase II, and baseline and follow-up. There were no significant differences between the groups at the end of follow-up (P > .05). Conclusion.,Electroacupuncture to distal points alone is effective for short-term symptomatic relief of tension-type headache. [source] Treating Chronic Tension-type Headache Not Responding to Amitriptyline Hydrochloride With Paroxetine Hydrochloride: A Pilot EvaluationHEADACHE, Issue 9 2003Kenneth A. Holroyd PhD Context.,In some individuals, chronic tension-type headache fails to respond to tricyclic antidepressant medications that often serve as first-line therapy. Objective.,To evaluate the clinical efficacy of paroxetine hydrochloride for chronic tension-type headache not responding to amitriptyline hydrochloride. Design and Setting.,Open-label trial of paroxetine conducted at 2 outpatient sites in Ohio. Participants and Intervention.,Thirty-one adults (mean age, 37 years; 20 women) with chronic tension-type headache (mean, 25 headache days per month) who had failed to respond (less than 30% improvement) to treatment with either amitriptyline (n = 13) or matched placebo (n = 18). All participants were treated with paroxetine (up to 40 mg per day) in a 9-month protocol. Outcome Measures.,Monthly headache index calculated as the mean of pain ratings (0 to 10 scale) recorded by participants in a diary 4 times per day, number of days per month with at least moderate pain (pain rating of 5 or greater), and analgesic medication use. Results.,In patients who had not responded to amitriptyline, paroxetine failed to reduce chronic tension-type headaches or analgesic medication use. In patients who had not responded to placebo, paroxetine produced modest reductions in chronic tension-type headaches and analgesic use. Conclusions.,We found no evidence that chronic tension-type headaches that failed to respond to tricyclic antidepressant therapy with amitriptyline improved when subsequently treated with paroxetine. More support was found for the efficacy of paroxetine in patients with chronic tension-type headaches who had failed to respond to placebo. [source] Use of the Migraine Disability Assessment Questionnaire in Children and Adolescents With Headache: An Italian Pilot StudyHEADACHE, Issue 7 2003D. D'Amico MD Objectives.,To determine the suitability of the Migraine Disability Assessment (MIDAS) Questionnaire for assessing disability in children and adolescents with headache and to obtain preliminary information about disability in different primary headaches. Background.,During the last decade, researchers have begun to employ standardized methodologies to investigate the global impact of primary headaches. Disease-specific instruments have been developed to measure headache-related disability. The MIDAS Questionnaire, which is the most extensively studied of these instruments, was designed to assess the overall impact of headaches over the 3 months before compilation. The MIDAS Questionnaire is an optimal tool to assess headache-related disability in adults. Methods.,Ninety-five patients aged 7 to 17 years with tension-type headache, migraine, or both completed the validated Italian form of the MIDAS questionnaire on 2 occasions. Test-retest reliability was assessed by the Spearman rank correlation test. The Cronbach , assessed internal consistency. The patients answered questions about the adequacy of the questionnaire. Results.,The Cronbach , was .8. Correlation coefficients were generally high for the overall MIDAS score and for the items investigating disability in school and in family/leisure activities; they were lower for the items about housework. Most patients thought that the MIDAS Questionnaire was useful (98.9%) and that it captured the impact of their headaches (58.9%); 41% thought that questions about disability in housework were useless, 44.2% suggested adding questions regarding inability to do homework. All primary headaches had a considerable impact on daily activities, but patients with migraine tended to have lower headache frequencies and lower total disability time; those with tension-type headache suffered more days in which activities, although performed, were substantially impaired. Conclusions.,The MIDAS Questionnaire is useful for assessing disability in children and adolescents with different primary headaches. Minimal changes in the phrasing and content of the items would be sufficient to render the MIDAS specific for the younger population with headache. [source] Factors Associated With Burden of Primary Headache in a Specialty ClinicHEADACHE, Issue 6 2003Eugene M. Cassidy MRCPsych Objective.,To examine factors associated with social, occupational, and psychological burden of common primary headache (migraine and tension-type headache). Background.,The personal and social burden of primary headache is high. Health, occupational, social, and psychological factors contributing to burden in people with disabling headache have not been fully unravelled. Methods.,One hundred eighty consecutive patients with either migraine or tension-type headache attending a specialty headache outpatient clinic for the first time were evaluated over a 9-month period. Headache subtype was operationally defined according to International Headache Society criteria. Headache frequency, duration, and severity were recorded. Occupational and social disability were quantified using the Migraine Disability Assessment questionnaire. Psychological burden was quantified using the 28-item General Health Questionnaire, the Beck Depression Inventory, and the State-Trait Anxiety Inventory. Premorbid vulnerability to life stress was quantified using the neuroticism subscale of the Eysenck Personality Inventory. Results.,Patients with frequent (chronic) headache scored higher on the Migraine Disability Assessment questionnaire and had higher Beck Depression Inventory and General Health Questionnaire depression scores than those with less frequent (episodic) headache. Frequency of headache, but not pain severity, duration, or diagnosis, predicted both Migraine Disability Assessment total disability and General Health Questionnaire/Beck Depression Inventory depression. Neuroticism was predictive of depression but not disability. Patients with chronic migraine had the highest depression and disability scores. Conclusion.,The number of days per month with headache is a key determinant of headache-related burden in those attending specialty clinics. Frequent (chronic) headache is associated with significantly higher psychopathology scores and general social impairment, but the direction of this relationship is not clear. Those with migraine and chronicity are the most impaired. [source] Effect of Autogenic Training on Drug Consumption in Patients With Primary Headache: An 8-Month Follow-up StudyHEADACHE, Issue 3 2003Terezia Zsombok MD Objective.,To examine the effects of Schultz-type autogenic training on headache-related drug consumption and headache frequency in patients with migraine, tension-type, or mixed (migraine plus tension-type) headache over an 8-month period. Background.,Behavioral treatments often are used alone or adjunctively for different types of headache. There are, however, only a few studies that have compared the efficacy and durability of the same treatment in different types of primary headache, and the effects of treatment on headache-related drug consumption rarely have been assessed even in these studies. Methods.,Twenty-five women with primary headache (11 with mixed headache, 8 with migraine, and 6 with tension-type headache) were evaluated via an open-label, self-controlled, 8-month, follow-up study design. After an initial 4 months of observation, patients began learning Schultz-type autogenic training as modified for patients with headache. They practiced autogenic training on a regular basis for 4 months. Based on data from headache diaries and daily medication records, headache frequencies and the amounts of analgesics, "migraine-specific" drugs (ergots and triptans), and anxiolytics taken by the patients were compared in the three subgroups over the 8-month period. Results.,From the first month of implementation of autogenic training, headache frequencies were significantly reduced in patients with tension-type and mixed headache. Significant reduction in frequency was achieved in patients with migraine only from the third month of autogenic training. Decreases in headache frequencies were accompanied by decreases in consumption of migraine drugs and analgesics resulting in significant correlations among these parameters. Reduction in consumption of anxiolytic drugs was more rapid and robust in patients with tension-type headache compared to patients with migraine, and this outcome failed to show any correlation with change in headache frequency. Conclusion.,Schultz-type autogenic training is an effective therapeutic approach that may lead to a reduction in both headache frequency and the use of headache medication. [source] Lifetime Prevalence and Characteristics of Recurrent Primary Headaches in a Population-Based Sample of Swedish TwinsHEADACHE, Issue 8 2002Dan A. Svensson MSc Objective.,To examine the lifetime prevalence and other characteristics of recurrent primary headaches in twins. Background.,The twin model may provide insights into the role of genetic and environmental influences in headache disorders. However, assumptions as to whether twins are representative of the general population, and whether monozygotic and dizygotic twins are similar have rarely been addressed. Methods.,The study population consisted of a random sample of 17- to 82-year-old twins from the Swedish Twin Registry (n = 1329). Structured interviews on the telephone by lay personnel and the International Headache Society criteria were used for assessment and diagnosis of recurrent primary headaches. Prevalence data of the general population for migraine and tension-type headache was obtained from various published reports. Results.,A total of 372 subjects (29%) had ever had recurrent headaches. In total, 241 recurrent headache sufferers fulfilled the criteria for migraine or tension-type headache, and the lifetime prevalence was 7.1% for migraine without aura, 1.4% for migraine always with aura, 1.9% for migraine occasionally with aura, 9.4% for episodic tension-type headache, and 1.3% for chronic tension-type headache. The lifetime prevalence of all migraine and all tension-type headache, including another 84 subjects fulfilling all but one of the criteria for migraine or tension-type headache, was 13.8% and 13.5%, respectively. The corresponding prevalence risk for women was 2.4 (95% confidence interval [CI] 1.7, 3.4) and 1.5 (95% CI 1.1, 2.1), respectively. Zygosity was not a significant predictor for migraine. In tension-type headache, the prevalence risk for dizygotic twins and unlike-sexed twins as compared with monozygotic twins was 1.9 (95% CI: 1.2, 3.1) and 1.8 (95% CI: 1.1, 2.9), respectively. Conclusion.,There is no twin-singleton or monozygotic-dizygotic difference for the risk of migraine. In tension-type headache, twins seem to have a lower risk than singletons, and this is especially true for monozygotic twins. [source] Chronic Bilateral Headache Responding to IndomethacinHEADACHE, Issue 10 2000Jan Hannerz MD Three patients with bilateral chronic tension-type headache (meeting IHS diagnostic criteria) responded with complete control of the headache during the more than 2 years they were treated with indomethacin. The headache recurred within 12 to 26 hours after indomethacin was stopped. Fifty milligrams of intravenous indomethacin resulted in complete relief of headache for 6.5 to 25 hours, similar to results found earlier in patients with hemicrania continua. It is concluded that there may be a subgroup of patients with bilateral chronic headache who respond to indomethacin in the group of patients otherwise diagnosed as having chronic tension-type headache. [source] Use of Percutaneous Electrical Nerve Stimulation (PENS) in the Short-term Management of HeadacheHEADACHE, Issue 4 2000Hesham E. Ahmed MD Objective.,To evaluate the short-term effects of percutaneous electrical nerve stimulation (PENS) in the management of three types of chronic headache. Background.,Traditional electroanalgesic therapies have been reported to be effective in the management of acute headache symptoms. However, no controlled studies have been performed in patients with chronic headache. Methods.,Thirty patients with either tension headache, migraine, or posttraumatic headache symptoms of at least 6 months' duration were randomized to receive PENS (needles with electricity) or "needles alone" according to a crossover study design. All treatments were administered for 30 minutes, three times a week for 2 consecutive weeks with 1 week off between the two different treatments. For the PENS treatments, an alternating electrical stimulation frequency of 15 and 30 Hz was used. Pain, activity, and sleep scores were assessed using a 10-cm visual analog scale, with 0 corresponding to the best and 10 to the worst, during the 48-hour period prior to the beginning of the two treatments, immediately before and after each treatment session, and 48 hours after completing each treatment modality. Results.,Compared with the needles alone, PENS therapy was significantly more effective in decreasing the overall VAS pain scores for tension-type headache, migraine and posttraumatic headache (58%, 59%, and 52% versus 20%, 15%, and 20%, respectively). Similarly, PENS therapy produced greater improvement in the patients' physical activity (41% to 58% for PENS versus 11% to 21% for needles only) and quality of sleep (41% to 48% for PENS versus 12% to 20% for needles only). However, there were no differences in the pattern of the response to PENS therapy among the three headache groups. Conclusions.,Percutaneous electrical nerve stimulation appears to be a useful complementary therapy to analgesic and antimigraine drugs for the short-term management of headache. Interestingly, the analgesic response to PENS therapy appears to be independent of the origin of the headache symptoms. [source] Dynamic Assessment of Abnormalities in Central Pain Transmission and Modulation in Tension-type Headache SufferersHEADACHE, Issue 2 2000Jonathan D. Neufeld PhD Objective.,To examine and compare central pain processing and modulation in young tension-type headache sufferers with that of matched healthy controls using an induced headache "challenge" paradigm. Background.,Recent research has suggested that abnormalities in central pain processing and descending pain modulation may contribute to chronic tension-type headache. These abnormalities, if they contribute to headache pathogenesis, should be present in young adult tension-type headache sufferers. Recent research using static measures of physiological variables, such as muscle tenderness and exteroceptive suppression, has identified chronic muscle tenderness as a characteristic of young tension-type headache sufferers, but other central nervous system functional abnormalities may require a dynamic "challenge" to be observed. Methods.,Twenty-four young women meeting the International Headache Society diagnostic criteria for tension-type headache (headache-prone) and a matched group of 24 healthy women who reported fewer than 10 problem headaches per year (control) participated in a double-blind, placebo-controlled, crossover study. Subjects completed jaw clenching and a placebo condition on different days in counterbalanced order. Pericranial muscle tenderness, pressure-pain thresholds on the temporalis, and exteroceptive suppression periods were assessed before and after each procedure. Head pain was recorded for 12 to16 hours following each condition. Results.,Headache-prone subjects were more likely than controls to experience headaches after both the jaw clenching and placebo procedures, but neither group was significantly more likely to experience headaches following jaw clenching than placebo. In pretreatment measurements, headache-prone subjects exhibited greater muscle tenderness than controls, but pressure-pain detection thresholds and exteroceptive suppression periods did not differ in the two groups. Control subjects showed increases in muscle tenderness and exteroceptive suppression periods following both the clenching and placebo procedures, whereas headache-prone subjects exhibited no significant changes in any of the physiological measures following either experimental manipulation. Conclusions.,These results confirm previous findings indicating abnormally high pericranial muscle tenderness in young tension headache sufferers even in the headache-free state. In addition, the results suggest that the development of headaches following noxious stimulation is more strongly related to headache proneness and associated abnormalities in central pain transmission or modulation (indexed by pericranial muscle tenderness and exteroceptive suppression responses) than muscle strain induced by jaw clenching. [source] Managing chronic headaches in the clinicINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 12 2004A.J. Dowson Summary Chronic daily headache (CDH), which is often linked to a history of migraine, tension-type headache and the abuse of headache medications, and cluster headache are the best known of the chronic headaches. These headaches may not be well recognised or well treated in primary care. This article outlines the development of management algorithms for these headache subtypes, designed for use by the primary care physician with an interest in headache. Principles of care for chronic headaches include implementation of screening procedures, differential diagnosis, tailoring of management to the individual's needs, proactive follow-up and a team approach to care. These principles can be customised to the headache subtype by the selection of appropriate therapies. The optimal treatments for CDH include physical therapy to the neck if there is any stiffness there, withdrawal of abused medications and treatment of any subsequent withdrawal symptoms and headache prophylaxis, together with the provision of acute medications as rescue therapy. Optimal treatments for cluster headache include short- and long-term prophylaxis to prevent the headaches developing and acute medications for use as rescue. If treatment is ineffective, alternative medications can be provided at follow-up, with the possibility of referral for refractory patients. [source] Referred Pain Elicited by Manual Exploration of the Lateral Rectus Muscle in Chronic Tension-Type HeadachePAIN MEDICINE, Issue 1 2009César Fernández-de-las-Peñas PT ABSTRACT Objective., To analyze the presence of referred pain elicited by manual examination of the lateral rectus muscle in patients with chronic tension-type headache (CTTH). Design., A case-control blinded study. Setting., It has been found previously that the manual examination of the superior oblique muscle can elicit referred pain to the head in some patients with migraine or tension-type headache. However, a referred pain from other extraocular muscles has not been investigated. Methods., Fifteen patients with CTTH and 15 healthy subjects without headache history were included. A blinded assessor performed a manual examination focused on the search for myofascial trigger points (TrPs) in the right and left lateral rectus muscles. TrP diagnosis was made when there was referred pain evoked by maintained pressure on the lateral corner of the orbit (anatomical projection of the lateral rectus muscle) for 20 seconds, and increased referred pain while the subject maintained a medial gaze on the corresponding side (active stretching of the muscle) for 15 seconds. On each side, a 10-point numerical pain rate scale was used to assess the intensity of referred pain at both stages of the examination. Results., Ten patients with CTTH (66.6%) had referred pain that satisfied TrPs diagnostic criteria, while only one healthy control (0.07%) reported referred pain upon the examination of the lateral rectus muscles (P < 0.001). The elicited referred pain was perceived as a deep ache located at the supraorbital region or the homolateral forehead. Pain was evoked on both sides in all subjects with TrPs, with no difference in pain intensity between the right and the left. The average pain intensity was significantly greater in the patient group (P < 0.001). All CTTH patients with referred pain recognized it as the frontal pain that they usually experienced during their headache attacks, which was consistent with active TrPs. Conclusion., In some patients with CTTH, the manual examination of lateral rectus muscle TrPs elicits a referred pain that extends to the supraorbital region or the homolateral forehead. Nociceptive inputs from the extraocular muscles may sustain the activation of trigeminal neuron, thus sensitizing central pain pathways and exacerbating headache. [source] Acupuncture for Chronic Pain: Is Acupuncture More than an Effective Placebo?PAIN PRACTICE, Issue 2 2010A Systematic Review of Pooled Data from Meta-analyses Abstract Objectives: There is controversy as to whether or not acupuncture is more effective than placebo. To help clarify this debate, we synthesized the evidence gathered from systematic reviews on the pooled data of high-quality randomized controlled trials comparing acupuncture to sham acupuncture for chronic pain. Method: Systematic reviews of acupuncture for the most commonly occurring forms of chronic pain (back, knee, and head) published between 2003 and 2008 were sourced from Ovid databases: Medline, Allied and Complementary Medicine database, Cochrane Library and Web of Science during December 2008. Eight systematic reviews with meta-analyses of pooled data were eligible for inclusion. Data were extracted for short- and longer-term outcomes for the most commonly occurring forms of pain. Two independent reviewers assessed methodological quality. Results: For short-term outcomes, acupuncture showed significant superiority over sham for back pain, knee pain, and headache. For longer-term outcomes (6 to12 months), acupuncture was significantly more effective for knee pain and tension-type headache but inconsistent for back pain (one positive and one inconclusive). In general, effect sizes (standardized mean differences) were found to be relatively small. Discussion: The accumulating evidence from recent reviews suggests that acupuncture is more than a placebo for commonly occurring chronic pain conditions. If this conclusion is correct, then we ask the question: is it now time to shift research priorities away from asking placebo-related questions and shift toward asking more practical questions about whether the overall benefit is clinically meaningful and cost-effective? [source] Visual and brainstem auditory evoked potentials in children with headachePEDIATRICS INTERNATIONAL, Issue 5 2008Bulent Unay Abstract Background: Headache is a common problem in the pediatric population. The purpose of the present study was to evaluate visual evoked potentials (VEP) and brainstem auditory evoked potentials (BAEP) in children with headache. Methods: Thirty-seven children fulfilling the International Headache Society Criteria for a diagnosis of migraine, 35 children with tension-type headache and 40 healthy children (control group) were enrolled in the study. Results: The mean age of patients and controls was 10.4 years. P100 latency and amplitudes of migraine patients were significantly higher than children with tension-type headache and control subjects. Children with tension-type headache also had higher P100 latency and amplitude values than control subjects but there was no statistical difference. BAEP responses were similar between all groups. Conclusion: Measurement of VEP latency and amplitude is a valuable and reliable test for the diagnosis of migraine and can be used safely in childhood. [source] | |||||||||||||||||||||||||
