O objetivo deste estudo foi avaliar o impacto da presença de dor miofascial, segundo o Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), no Limiar de Dor à Pressão (LDP) da musculatura mastigatória de mulheres portadoras de enxaqueca, fora da e durante a crise de enxaqueca. Adicionalmente, comparar índices de depressão e prevalência de apertamento dentário diurno e bruxismo do sono em mulheres com enxaqueca, com e sem o diagnóstico adicional de DTM. A amostra foi coletada no Ambulatório de Cefaléia do Hospital Geral de Fortaleza (HGF) e nas clínicas da Faculdade de Odontologia de Bauru da Universidade de São Paulo (FOB-USP), e foi composta por 101 voluntárias do sexo feminino, com idade variando entre 18 e 60 anos, com diagnóstico de enxaqueca previamente confirmado por neurologista. Para classificar as voluntárias em portadoras de DTM ou não, utilizou-se o RDC/TMD. Após aplicação do RDC/TMD, as voluntárias foram separadas em dois grupos: grupo I, pacientes portadoras de enxaqueca, sem DTM; e grupo II, pacientes portadoras de enxaqueca e DTM. Mais dois grupos (49 mulheres assintomáticas e 50 portadoras de dor miofascial) foram acrescentados ao estudo, utilizando-se dados originais e individuais de estudo previamente realizado com voluntárias brasileiras com características semelhantes a dos outros grupos obtidos neste estudo. Estes dois grupos foram utilizados para análise inicial do LDP. O LDP das voluntárias do grupo I e II foram avaliadas em dois momentos: inicialmente, na ausência de dor de origem cefálica, e durante uma crise de enxaqueca. As medições do LDP foram realizadas com a utilização de um algômetro, em 4 pontos localizados bilateralmente, nos músculos temporal (anterior, médio e posterior) e masséter (corpo). Para avaliação do índice de depressão, utilizou-se o Symptom Checklist 90 (SCL-90) do eixo II do RDC/TMD. Para o verificação da presença de apertamento dentário diurno utilizou-se o auto-relato e, para verificação da presença de bruxismo do sono, as voluntárias preenchiam um questionário composto por 6 perguntas referentes ao hábito. Os dados obtidos foram submetidos à análise estatística (ANOVA a um critério, testes de comparações múltiplas de Tukey, teste t pareado, teste tde Student e teste qui-quadrado) em um nível de significância de 5%. verificou-se que mulheres portadoras de enxaqueca,quando comparadas a grupo assintomático, apresentaram diminuição estatisticamente significante do LDP em todos os sítios musculares avaliados, e que houve tendência de diminuição no LDP de mulheres portadoras de enxaqueca e DTM, quando comparadas a mulheres com enxaqueca. Durante a crise, houve diminuição estatisticamente significante no LDP dos dois grupos, independente da presença ou não de DTM. Mulheres portadoras de enxaqueca e DTM apresentaram níveis de depressão estatisticamente maiores e maior prevalência de apertamento dentário diurno e bruxismo do sono. A enxaqueca e a DTM parecem estar associadas pela sensitização dos nociceptores e conseqüente sensitização central. / The objective of this study was to assess the impact of miofascial pain, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), on the pressure pain thershold (PPT) of masticatory muscles in women with migraine, during a migraine attack and in the absence of it. Moreover, the study compared depression scores, daytime clenching and sleep bruxism prevalence in women with migraine, with and without TMD. The sample comprised 101 women, with ages ranging from 18 to 60 years, with migraine diagnostic previously confirmed by a neurologist. All subjects were evaluated using RDC/TMD in order to determinate the presence of TMD, and were divided in two groups: group I, women with migraine, and group II, women with migraine and TMD. Two more groups (49 symptom-free women and 50 women with miofascial pain), matched for gender and race, which were obtained from a previously study, were added to this study. These two groups were used for initial analysis of PPT. PPT from groups I and II were measured in the during a migraine attack and in the absence of it. The PPT values of masseter and temporalis (anterior, middle and posterior regions) muscles were recorded bilaterally with a pressure algometer. Depression level was determinate by the SCL-90 from RDC/TMD axis II, and a self-reported questionnaire was used to detect parafunctional habits. One-way ANOVA, tukey test for pairwise comparisons, paired t-test, students t-test and chi-square, were used in statistical analysis with a 5% significance level. Women with migraine showed statistically lower PPT levels at all points tested, when compared with symptom-free women. Woman with migraine and TMD showed a tendency of decrease on PPT levels at all points tested, when compared with women with migraine. During a migraine attack, PPT levels were decreased in both groups. Women with migraine and TMD showed statistically higher depression levels and higher prevalence of both bruxism and daytime clenching. This study suggests that migraine and TMD may be associated with sensitization of first-order peripheral nociceptors and consequent central sensitization.

Objetivo: Investigar a mobilidade cervical e do segmento C1/C2 com o Flexion Rotation Test (FRT) em pacientes com migrânea crônica e episódica, e analisar a influência da cronicidade, da incapacidade cervical e da alodinia cutânea nessa mobilidade. Métodos: Foram avaliadas 85 mulheres com idade de 18 a 55 anos divididas em três grupos: migrânea crônica (MC)(n=25), migrânea episódica (ME)(n=30) e controle (n=30). O FRT e a avaliação da amplitude de movimento cervical foram avaliados com o instrumento CROM® acoplado a cabeça. Foram realizadas três repetições de cada movimento, aleatorizadas previamente. A média das repetições foi utilizada para a análise dos dados. A incapacidade cervical foi avaliada pelo Neck Disability Index e a alodinia cutânea pelo Allodynia Symptom Checklist (ASC-12). Quanto a mobilidade, os grupos foram comparados utilizando o teste Manova com pós teste de Bonferroni. A razão de prevalência foi utilizada para identificar a associação entre o diagnóstico de migrânea e a cronicidade com a mobilidade do segmento C1/C2. A regressão linear simples foi usada para identificar a influência da incapacidade cervical e da alodinia cutânea no FRT. Resultados: Todos os grupos diferiram nos valores do FRT (MC = 25.79º e 26.81º; ME = 33.44º e 32.18º; controle= 41.98º e 40.18º; nos movimentos a direita e esquerda, respectivamente, p<0.05). Apenas o grupo MC diferiu na amplitude de movimento cervical (p<0.05) do grupo controle em todos os movimentos. Pacientes com migrânea apresentaram 2.85 vezes mais associação ao risco de apresentar hipomobilidade no segmento C1/C2 comparado aos controles. A incapacidade cervical influenciou em 19% a amplitude desse segmento independente do diagnóstico de migrânea, enquanto que a alodinia cutânea não apresentou influência significativa. Conclusão: Mulheres com migrânea apresentam reduzida amplitude de movimento cervical, especialmente no segmento C1/C2, e maior risco de desenvolver hipomobilidade cervical superior comparado a mulheres sem cefaleia, sendo este risco aumentado pela cronicidade da doença. Além disso, a incapacidade cervical influencia no resultado do FRT, contrariamente a alodinia cutânea / Objective: To investigate the cervical and C1/C2 mobility with the Flexion Rotation Test (FRT) in patients with chronic and episodic migraine, and analyze the influence of the chronicity, cervical disability and cutaneous allodynia in this mobility. Methods: Were analyzed 85 women with age between 18 and 55 years, divided in three groups: chronic migraine (CM)(n=25), episodic migraine (EM)(n=30) and control (n=30). The FRT and cervical range of motion has been applied with the CROM® device coupled to the head. Were conducted three repetitions of each movements, randomized previously. The mean of the repetitions was used for data analysis. Cervical disability was assessed by the Neck Disability Index and cutaneous allodynia by the Allodynia Symptom Checklist (ASC-12). As for mobility, the groups were compared using MANOVA test with post-hoc de Bonferroni. The prevalence ratio was used to identify the association between the migraine diagnostic and chronicity with C1/C2 mobility, and simple linear regression was used to identify the influence of cervical disability and cutaneous allodynia in FRT. Results: All groups differed in the FRT (CM = 25.79º and 26.81º; EM = 33.44º and 32.18º; control = 41.98° and 40.18º; right and left movements, respectively, p <0.05). Only, CM group differed in cervical range of motion (P <0.05) to the control group in all movements. Migraine patients shows 2.85 times more association with risk for C1/C2 hypomobility compared to controls. Cervical disability influenced by 19% the ranger of this segment independent the diagnosis of migraine, while the cutaneous allodynia has not a significant influence. Conclusion: Women with migraine have reduced cervical range of motion, especially in the C1/C2 segment, and higher risk of develop superior cervical hypomobility compared to women without headache, and this risk was increased by the chronicity. Also, cervical disability influence the FRT, in contrast to cutaneous allodynia

A migrânea está relacionada às disfunções das estruturas da coluna cervical, impulsos aferentes desse local podem ser facilitadores ou mesmo gatilhos da dor. Tratamentos com manipulação cervical isolada e combinada a medicação já foram testados, porém os resultados são conflitantes. O objetivo desse trabalho foi avaliar o efeito adicional da fisioterapia ao tratamento medicamentoso da migrânea na frequência, intensidade e duração da dor de cabeça. Foram inclusas mulheres com migrânea, na faixa etária de 18 e 55 anos, com mínimo de 06 dias de dor por mês, e que apresentasse dor na região craniocervical através do relato. Cinquenta mulheres foram igualmente randomizadas para um dos dois grupos de tratamento, Grupo Fisioterapia (terapia manual + medicação) e Grupo Controle (medicação). O diagnóstico de migrânea foi realizado por uma única neurologista, segundo a Classificação Internacional de Cefaleias. Foram realizadas 12 sessões de terapia manual, duas vezes por semana, durante 50 minutos, por uma única fisioterapeuta. A avaliação, a reavaliação e follow-up foram cegos. Os desfechos primários de frequência, intensidade e duração da dor de cabeça, foram avaliados por meio do diário de dor; e secundários, Limiar de dor por pressão (Algômetro), incapacidade relacionada à cefaleia (Migraine disability assessment program) e a coluna cervical (Neck disability índex), Patient Health Questionnaire eight-item depression scale (PHQ-8), alodinia com Allodynia Sympton Checklist (ASC- /12) e satisfação com Patients Global Impression of Change Scale (PGIC). A análise foi realizada por intenção de tratamento e foi utilizado o Modelo Linear de efeitos mistos e para atribuir relevância clínica o Effect size (ES) e Mínima mudança importante (MID). Não foram observadas diferenças entre os grupos na avaliação inicial. O GF apresentou redução de 37% na frequência de dias de dor de cabeça comparado ao GC que apresentou 22% (p<0.05 e ES 0,4) e (p<0.05 e ES 0,3) respectivamente. Não foram observadas diferenças clínicas significativas entre os grupos na duração e na intensidade da dor de cabeça. Também foi observado aumento significativo (p<0,05) do limiar de dor por pressão, bem como maior satisfação e percepção de mudança da doença ao paciente (p<0,05) no GF em comparação ao GC. Não foram observadas diferenças significativas nos demais parâmetros avaliados. A redução do limiar de dor dos músculos cervicais com o tratamento fisioterapêutico promoveu um efeito benéfico adicional ao medicamentoso, com maior redução da frequência de dias de dor de cabeça e maior satisfação e percepção de melhora dos pacientes. REBEC nº RBR-6kvx74 / Migraine is related to disorders of the cervical spine structures, afferent impulses that location can be facilitators or even triggers pain. Treatments with cervical manipulation alone and combined medication have been tested, but results are conflicting. The aim of this study was to evaluate the additional effect of physical therapy to drug treatment of migraine in frequency, intensity and duration of headache. Women with migraine were included, aged 18 to 55 years, with a minimum of 06 days of pain per month and report of pain in the craniocervical region. Fifty women were equally randomized to one of the two treatment groups, Physiotherapy Group (manual therapy and medication) and control group (medication). The diagnosis of migraine was performed according to the International Classification of headache by a single neurologist. All subjects received similar medications. 12 sessions of manual therapy, twice per week, during for 50 minutes, were done by same physical therapist. The assessment, revaluation and follow-up were blind. The primary endpoints of frequency, intensity and duration of headache were evaluated through diary pain, and secondary endpoints like pain threshold pressure (algometer), headache related disability (Migraine disability assessment program) and cervical spine (Neck disability index), patient Health Questionnaire eight- item depression scale (PHQ-8), with the severity of Allodynia Sympton Checklist (ASC-12) and patients Global Impression of Change Scale to assess satisfaction and perception of patient changes as its disease condition. The analysis was by intention to treat and we used the linear mixed effects model. To assign the clinical relevance Effect size (ES) and Minimum important change (MID) were used. No differences between groups were observed at baseline. The PG showed a 37% reduction in the frequency of headache days compared to GC showed that 22 % (p<0.05 to ES0.4) and (p<0.05 to ES0.3) respectively. No clinically significant differences were observed between groups regarding the duration and intensity of the headache. Significant increase (p<0.05) pain threshold pressure was also observed, as well as greater satisfaction and changing perception of the disease to the patient (p<0.05) in the PG compared with the CG. No significant differences were observed in the other parameters. The reduction of the pain threshold of cervical muscles with physical therapy promoted a beneficial additional effect to medication, with greater reduction in frequency of headache days and greater satisfaction and perceived improvement of patients.

Objetivos: Avaliar o comportamento da pressão arterial (PA) e da frequência cardíaca (FC) durante a fase de dor da migrânea em pacientes sem hipertensão arterial sistêmica (HAS). Avaliar essas variáveis em função da intensidade de dor e se elas sofrem influência do uso agudo de ibuprofeno. Métodos: Dez pacientes (nove mulheres), entre 21 e 43 anos, com diagnóstico de migrânea foram selecionados. Todos tinham diagnóstico de migrânea sem aura e quatro deles também tinha diagnóstico de migrânea com aura. Eles apresentavam de 3 a 11 dias de dor por mês, não tinham qualquer outro problema de saúde e não estavam em tratamento profilático para migrânea. Além disso, não utilizavam medicamentos que pudessem interferir na PA ou FC. Os pacientes foram submetidos à anamnese e exame físico. Para descartar HAS, foram submetidos a medições convencionais da PA e Medidas Ambulatoriais da Pressão Arterial por 24h. A aquisição das medidas de PA e FC nos períodos livres de dor (interictal) foram realizadas por meio de Medidas Residenciais da Pressão Arterial (MRPA) por quatro a cinco dias consecutivos, com a obtenção de seis medidas ao dia. Para a aquisição das medidas de PA e FC no período de dor da migrânea (ictal), os pacientes foram orientados a fazer MRPA a cada 10 minutos nas duas primeiras horas de dor e, após, a cada 15 minutos até o final da crise. Ainda, deveriam assinalar em um tipo de diário de cefaleia as características da dor a cada hora. Permitiu-se o uso de 400mg de ibuprofeno como tratamento de resgate após o final da segunda hora de dor. Para análise estatística, comparamos os valores de pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), pressão arterial média (PAM) e FC realizadas no período interictal com as realizadas no período ictal. As variáveis obtidas durante a cefaleia foram comparadas em função da intensidade de dor e em função do uso de ibuprofeno. Resultados: As médias de PAS, PAD, PAM do período ictal foram significativamente menores que as do período interictal (p0,01). Comparando as médias dos valores de PAS, PAD, PAM e FC do período interictal com as do período ictal divididas por hora para as primeiras quatro horas de dor, observamos que houve uma redução progressiva dos valores de PAS, PAD e PAM durante todo esse período (p0,01). Quanto à FC, observamos que houve aumento de seus valores na primeira hora de dor (p0,02). Houve uma tendência de redução dos valores das médias de PAS, PAD e PAM nas dores de moderada e forte intensidade. Com relação ao ibuprofeno, não notamos diferenças nas variáveis. Conclusões: Durante a fase de dor da migrânea ocorre uma redução da PA desde a primeira hora de dor. Por outro lado, há um aumento dos valores da FC apenas na primeira hora de dor. Houve uma tendência de que os valores de PA reduzissem à medida que a dor progredisse de leve para moderada e forte intensidades. O uso de 400mg de ibuprofeno não promoveu alterações nas variáveis analisadas. / Objectives: To analyse the behavior of blood pressure (BP) and heart rate (HR) during migraine headache in patients without hypertension (HBP). To assess the values of BP and HR according to the intensity of pain, and to check if those variable are influenced by 400 mg of ibuprofen. Methods: Ten patients (nine women), 21 to 43 years-old, with migraine diagnosis were select. All of them had migraine without aura and four of them also had migraine with aura. They had from 3 to 11 days of headache a month, no other healthy problem, and werent on migraine prophylactic treatment. Also, they werent using other drugs that could interfere on BP and HR. Patients were submitted to anamnesis and physical examination. Hypertension was ruled out through office and ambulatory BP measurements for 24 hours. To obtain the values of pain-free period, BP and HR were measured through home measurements which were done from 4 to 5 consecutives days, 6 times a day. To obtain the values of migraine headache period, patients were asked to measure their BP and HR from the beginning to the end of the attack. During the first two hour of pain, they should do the measures each 10 minutes, and after that each 15 minutes until the end of the attack. During the last procedure, patients should write in a kind of headache diary their headache characteristics each hour. Using of 400 mg of ibuprofen was just allowed at the end of the second hour of pain. To statistical analysis, the values of systolic (SBP), diastolic DBP), mean (MBP) blood pressure and HR from pain-free period were compared with the values of these variables from headache period. The values of these variables from headache period were also compared according the intensity of pain and the intake of ibuprofen. Results: The mean values of SBP, DBP and MBP from headache period were statistically lower than those from pain-free period (p0,01). Comparing mean values of SBP, DBP, MBP and HR from pain-free period to means from the headache period, separated by hour, for the first 4 hours of pain, we verified there were a progressive reduction of SBP, DBP, MBP during this phase (p0,01). About the HR, we noticed its values raised during the first hour of pain (p0,02). There was a trend of SBP, DBP and MBP values to be lower during moderate and severe pain. Regarding the use of ibuprofen, we didnt notice differences on BP or HR values. Conclusions: During migraine headache, BP values are lower since the first hour of pain. On the other hand, HR values were different just in the first hour of pain where they were higher. There was a trend of BP lowering as the pain progressed from mild to moderate and severe intensity. Ibuprofen (400 mg) didn\'t change the variables values.

Bakgrund: Migrän är en neurovaskulär sjukdom som yttrar sig i form av huvudvärksattacker. Som en del av migränbehandlingen rekommenderas regelbunden träning mellan anfallen. Studier visar dock att personer med migrän är mindre fysiskt aktiva än friska personer. Rörelserädsla (kinesiofobi) och tilltron till sin förmåga att vara fysiskt aktiv (self-efficacy för fysisk aktivitet) är två faktorer som kan påverka den fysiska aktivitetsnivån. Syfte: Beskriva förekomst av fysisk aktivitetsnivå, kinesiofobi och self-efficacy för fysisk aktivitet samt sambanden mellan dessa variabler hos personer med migrän. Metod: Studien var en tvärsnittsstudie med deskriptiv och korrelerande design. Totalt 29 personer med migrän från neurologmottagningen vid Akademiska sjukhuset i Uppsala inkluderades. Datainsamling skedde via självskattningsformulär samt ett formulär med bakgrundsinformation. Utfallsmåtten var fysisk aktivitetsnivå, kinesiofobi och self-efficacy för fysisk aktivitet. Resultat: Cirka 76 % av deltagarna nådde rekommendationerna för fysisk aktivitet. Deltagarna hade en relativt hög grad av både kinesiofobi och self-efficacy för fysisk aktivitet. Sambandet mellan fysisk aktivitetsnivå och grad av kinesiofobi var lågt till måttligt r = -0,49 (p = 0,01), och mellan fysisk aktivitetsnivå och self-efficacy för fysisk aktivitet var sambandet måttligt r = 0,56 (p &lt;0,01). Konklusion: I studien sågs ett samband mellan fysisk aktivitetsnivå, kinesiofobi och self-efficacy för fysisk aktivitet hos personer med migrän. Dessa samband verkade framförallt gälla fysisk träning och inte vardagsmotion. / Background: Migraine is a neurovascular disease causing recurring headache attacks. As part of the treatment, exercise is recommended. Studies show that individuals with migraine are less physically active than healthy individuals. Fear of movement (kinesiophobia) and self-efficacy for physical activity are two factors that may influence the level of physical activity. Aim: To describe level of physical activity, kinesiophobia and self-efficacy for physical activity and the correlation between these variables among individuals with migraine. Method: The study was cross-sectional with a descriptive and correlative design. A total of 29 individuals with migraine were recruited from the Department of Neurology at the University Hospital of Uppsala. The participants completed self-reported questionnaires including background information. The outcome measures were level of physical activity, kinesiophobia and self-efficacy for physical activity. Results: Approximately 76% reached the recommendations for physical activity. The participants scored a relatively high level of both kinesiophobia and self-efficacy for physical activity. The correlation between level of physical activity and level of kinesiophobia was low to moderate r = -0,49 (p = 0,01), and the correlation between level of physical activity and self-efficacy for physical activity was moderate r = 0,56 (p &lt;0,01). Conclusion: There was a correlation between level of physical activity, kinesiophobia and self-efficacy for physical activity among individuals with migraine. These correlations only seem to concern exercise.

Migraines are recurrent debilitating headaches that predominately afflict young women. The pathophysiology of migraines is still not well understood but is related to neurovascular dysfunction. Meningeal blood vessel dilation, extravasation of pro-inflammatory cytokines and activation of trigeminal afferent neurons promote migraine generation. Serotonin (5-HT) is an endogenous vasoactive peptide with diverse physiology. In meningeal blood vessels, serotonin causes vasoconstriction, however in coronary arteries, serotonin causes both vasodilation and vasoconstriction. In diseased coronary arteries, with impaired endothelial function, vasoconstriction predominates. Selective meningeal blood vessel serotonin agonists, termed ‘triptans’, have become the therapy of choice for migraine headaches. However, due to their constrictive effects on the coronary vasculature, triptans are not recommend in patients with known coronary artery disease, patients with greater than one coronary artery risk factor or patients with atherosclerotic cardiovascular disease risk (ASCVD) greater than ten percent. Triptan associated chest pain is a well-known phenomenon. Age, hypertension, dyspepsia, and Raynauds phenomenon are associated with triptan associated chest pain. Hypertension is the strongest risk factor for triptan associated chest pain in males. Although triptan associated chest pain is assumed to be cardiovascular due to its constrictive effect on the coronary vasculature, only a few cases of myocardial infarction, with documented ST elevation and/or troponin elevation, have been reported. Herein we report the case of a male patient with inferolateral ST elevation myocardial infarction, within minutes of receiving subcutaneous sumatriptan for migraine headache. The patient had a normal echocardiogram and electrocardiogram prior to sumatriptan use, and a normal cardiac catheterization afterwards.

Bakgrund: Enligt ”the Global burden of disease 2015” är migrän den tredje ledande orsaken tillfunktionshinder hos kvinnor och män under 50 år, i världen. I Sverige är prevalensen för migrän 14%. Orsaken till migrän är okänt. Kartlagt är att det finns neurofysiologiska, vaskulära och ärftliga komponenter. Migrän läkemedelbehandlas i allmänhet. De fysioterapeutiska åtgärderna är få och i regel inriktade på olika livsstilsfaktorer. Akupunktur skulle kunna vara ett behandlingsalternativ om det finns forskning som styrker dess effekt. Syfte: Genom att granska randomiserade kontrollerade studier som rör akupunkturbehandling vid migrän hos vuxna, skapa en bild av tillförlitligheten till interventionen och dess eventuella effekter på smärta, livskvalitet, migränanfallens frekvens och duration. Metod: Detta är en litteraturstudie och sökningen gjordes i databaserna Pubmed och Cochrane, populationen var vuxna med migrän, med eller utan aura. Kvalitetsgranskningen av studierna skedde med PEDro-skalan och den sammanvägda tillförlitligheten till resultaten graderades med GRADEstud. Resultat: Sökningen resulterade i sju artiklar, vilkas intervention var akupunktur enligt traditionellkinesisk medicin. Artiklarna var av måttlig till hög kvalitet, 4–9 poäng, och den sammanvägdatillförlitligheten till effekten av akupunkturbehandling graderades som måttligt hög för livskvalitet och antal migrändagar, och som låg för smärta och antal migränanfall. Sammanfattning: Vid jämförelser med tidigare forskning var samstämmigheten låg gällande tillförlitligheten. Fler studier av hög kvalitet behövs för att med säkerhet kunna uttala sig om akupunkturbehandlingens effekt vid migrän hos vuxna. / Background: According to “the Global Burden of Disease 2015”, migraines are the third leading cause of disability in the world, in women and men under the age of 50. In Sweden, the prevalence of migraines is 14%. What causes migraines is unclear, known is that there are neurophysiological, vascular, and hereditary components. Migraines are generally treated with medicine and the physiotherapeutic treatments usually focus on different lifestyle factors. Acupuncture could be a treatment option if there is research to prove its efficacy. Aim: By reviewing randomized controlled trials related to acupuncture in migraines in adults, get an understanding of the reliability of the intervention and its possible effects on pain, quality of life, frequency, and duration. Method: The search of literature to this study was made in the PubMed and Cochrane databases. The included population was adults with migraines, with or without aura. The quality review of the studies was done with the PEDro scale and the aggregated reliability to the results was graded with GRADEstud. Result: The search resulted in seven articles, in which the interventions were acupuncture according to traditional Chinese medicine. The articles were of moderate to high quality and the reliability to the effect of acupuncture was graded as moderately high for quality of life and number of migraines days and graded as low for pain and number of migraine attacks. Summary: When comparing with previous research, consistency was low in reliability. More high-quality studies are needed to reach a conclusion about the effect of acupuncture treatment on migraines in adults.

Introduction:  Migraine is a chronic neurological disease, partly hereditery. One non-pharmacological alternative treatment is yoga, whose effects have been investigated in a few scientific studies. No one has in a scientific studie investigated the effect of medical yoga for patients with migraine. Aim: The primary aim was to investigate if medical yoga in combination with pharmcological treatment could have an effect on headache frequency, intensity, and/or duration for patients with episodic and chronic migraine. Method: A pilot study, with SSED-design, with seven patients. Everyone had different long baselines before intervention. The intervention was a period of sex weeks of medical yoga. A headache diary with frequency, intensity and duration was conducted throughout the study period. Results: For two patients (patient two and six) the number of days with migraine reduced, effectsize (ES) 0,50 and 0,39 respectively. For four the freguence increased. The experience of pain decreased for two patients, increased for three and unchanged for one. The duration of migraine is reduced for one patient (patient seven) and increased for five. Some are improved in secondary outcome measures. Conclusion: At present, the intervention can possibly be used for patients who are similar to the individuals who had effect of the intervention and are interested in medical yoga as a self-care, but further studies are needed, as well as larger studies to be able to generalize to the migraine group. / Introduktion: Migrän är en kronisk neurologisk sjukdom, delvis ärftlig. En icke farmakologisk alternativ behandling är yoga, vars effekter har undersökts i några få vetenskapliga studier, men ingen har i en vetenskaplig studie undersökt effekten av MediYoga för patienter med migrän. Syfte: Primärt syfte var att undersöka om MediYoga i tillägg till farmakologisk behandling kunde ha effekt på huvudvärksfrekvens, intensitet och/eller duration hos patienter med episodisk och kronisk migrän. Metod: Pilotstudie med SSED-upplägg, och multipel baslinjedesign med totalt sju patienter. Alla hade olika långa baslinjer innan intervention. Interventionen var sex veckors Mediyoga. Huvudvärksdagbok med frekvens, intensitet och duration fördes under hela studietiden. Rultat: För två patienter (patient två och sex) minskade antalet dagar med migrän, effektstorlek (ES) 0,50 respektive 0,39. För fyra ökade frekvensen. Upplevelsen av smärta minskade för två patienter, och ökade för tre samt oförändrad för en. Durationen av migrän minskade för en patient (patient sju) och ökade för fem. Några förbättrades i sekundära utfallsmått. Slutsats: I dagsläget kan interventionen möjligen nyttjas för enstaka patienter som liknar de individer som haft effekt av interventionen och är intresserade av MediYoga som egenvård, men det behövs ytterligare, samt större studier för att kunna generalisera till gruppen migräniker.

abstract: Semi-supervised learning (SSL) is sub-field of statistical machine learning that is useful for problems that involve having only a few labeled instances with predictor (X) and target (Y) information, and abundance of unlabeled instances that only have predictor (X) information. SSL harnesses the target information available in the limited labeled data, as well as the information in the abundant unlabeled data to build strong predictive models. However, not all the included information is useful. For example, some features may correspond to noise and including them will hurt the predictive model performance. Additionally, some instances may not be as relevant to model building and their inclusion will increase training time and potentially hurt the model performance. The objective of this research is to develop novel SSL models to balance data inclusivity and usability. My dissertation research focuses on applications of SSL in healthcare, driven by problems in brain cancer radiomics, migraine imaging, and Parkinson’s Disease telemonitoring. The first topic introduces an integration of machine learning (ML) and a mechanistic model (PI) to develop an SSL model applied to predicting cell density of glioblastoma brain cancer using multi-parametric medical images. The proposed ML-PI hybrid model integrates imaging information from unbiopsied regions of the brain as well as underlying biological knowledge from the mechanistic model to predict spatial tumor density in the brain. The second topic develops a multi-modality imaging-based diagnostic decision support system (MMI-DDS). MMI-DDS consists of modality-wise principal components analysis to incorporate imaging features at different aggregation levels (e.g., voxel-wise, connectivity-based, etc.), a constrained particle swarm optimization (cPSO) feature selection algorithm, and a clinical utility engine that utilizes inverse operators on chosen principal components for white-box classification models. The final topic develops a new SSL regression model with integrated feature and instance selection called s2SSL (with “s2” referring to selection in two different ways: feature and instance). s2SSL integrates cPSO feature selection and graph-based instance selection to simultaneously choose the optimal features and instances and build accurate models for continuous prediction. s2SSL was applied to smartphone-based telemonitoring of Parkinson’s Disease patients. / Dissertation/Thesis / Doctoral Dissertation Industrial Engineering 2019
