OBJETIVOS: Validar o uso de questionários multidimensionais, como o Inventário Resumido da Dor (BPI) e o Questionário de Dor de McGill (MPQ) no pós-operatório da ceratectomia fotorefrativa (PRK). Comparar o perfil da dor no pós-operatório da PRK entre os dois olhos operados sob as mesmas condições e verificar preditores de dor como sexo, estado de ansiedade, conhecimento prévio da cirurgia e equivalente esférico do erro refrativo (EEER). MÉTODOS: Oitenta e seis olhos de 43 pacientes submeteram-se à PRK com intervalo de 14 dias entre cada olho. Uma hora antes da cirurgia, os pacientes responderam ao Inventário de Estado de Ansiedade (IDEA). No pós-operatório os pacientes receberam tratamento usual para dor e responderam aos questionários Escala Visual Analógica (EVA), BPI e MPQ após uma, 24, 48, 72 e 96 horas. Estudaram-se a consistência interna e as correlações de cada questionário. Compararam-se as pontuações de dor e a ansiedade entre primeiros e segundos olhos operados usando o teste de Wald, pareados através do teste t de Student. Utilizou-se o teste de Wald para comparar o comportamento da dor de acordo com sexo e EEER. RESULTADOS: Os questionários MPQ e BPI demonstraram alta consistência interna. Os questionários apresentaram pontuações mais elevadas na primeira mensuração da EVA (4.93 ± 2.38), MPQ - Índice de Estimativa de Dor (PRI) (26.95 ± 10.58), BPI - Índice de Intensidade de Dor (IID) (14.53 ± 7.36) e o BPI - índice de Interferência Funcional de Dor (IIFD) (22.30 ± 15.13), reduzindo-se gradativamente a cada momento subseqüente de avaliação. O MPQ-PRI na subescala subjetiva, apresentou curva de dor com redução lentificada. Todas as escalas apresentaram redução média estatisticamente significativa de um momento para o outro (p < 0.05) no pósoperatório, exceto no MPQ-PRI Subjetivo. Observaram-se correlações positivas entre as subescalas BPI e MPQ com a EVA (p < 0.05). Não houve diferença estatisticamente significativa nas pontuações de dor da EVA, BPI e MPQ-PRI entre ambos os olhos para todos os momentos avaliados. Os pacientes estavam menos ansiosos antes da PRK do segundo olho (p < 0.001), mas isto não apresentou correlação com níveis de dor após a cirurgia. O sexo e o conhecimento prévio do procedimento cirúrgico não influenciou significativamente em qualquer das escalas de dor. O EEER entre -3D to -5D correlacionou-se (p=0.035) com o BPI. CONCLUSÃO: O BPI e o MPQ apresentaram boas propriedades psicométricas em relação a confiabilidade e validade. Questionários multidimensionais fornecem uma avaliação mais abrangente sobre o perfil de dor após a PRK, se comparados à EVA, principalmente nos aspectos afetivos e cognitivos. O perfil da dor pósoperatória da PRK apresentou-se similar em ambos os olhos sob as mesmas condições. O EEER entre -3D to -5D foi o único fator preditor deste estudo para elevado nível de dor pós-operatória / PURPOSE: to validate the use of multidimensional questionnaires, such as the Brief Pain Inventory (BPI) and the McGill Pain Questionnaire (MPQ) in the postoperative photorefractive keratectomy (PRK). To compare the profiles of postoperative PRK pain between both eyes operated under the same conditions and to verify the preoperative predictors of pain such as gender, anxiety, knowledge of the procedure, and spherical equivalent refractive error (SERE). METHODS: eighty-six eyes of 43 patients with myopia underwent PRK in both eyes at an interval of 14 days between the procedures. One hour before surgery, subjects answered the State Anxiety Inventory (SAI). After surgery, usual PRK pain treatment was given and subjects answered to the Visual Analogue Scale (VAS), BPI and MPQ pain questionnaires at one, 24, 48, 72 and 96 hours intervals. The internal consistency was evaluated and convergent validity of each questionnaire was assessed using correlation testing. Pain scores and anxiety were compared between each eye using the Wald test and paired Student t test. Wald test was also used to test gender and SERE for each eye separately. RESULTS: both BPI and MPQ questionnaires showed internal consistency higher than 0.70. Subjects reported higher postoperative pain scores at the first measurement of the VAS (4.93 ± 2.38), MPQ - Pain Rating Index (26.95 6 10.58), BPI - Pain Severity Index (14.53 ± 7.36), and BPI- Pain Interference Index (22.30 ± 15.13) with decreasing scores at each subsequent observation period in all scales. All scales showed statistically significant (p < 0.05) pain reduction from one measurement to the next postoperatively, except the MPQ-PRI Evaluative. The majority of the scales and subscales showed a statistically significant (p < 0.05) direct correlation with the VAS at all of the evaluation periods. There were no statistically significant differences between the two eyes at all examination intervals regarding the VAS, BPI, and MPQ scores. Subjects were less anxious on average before the second surgery compared to the first surgery (p < 0.001), but this finding was not related to pain ratings after surgery. Gender and knowledge of the procedure did not significantly interfere with any scale of pain. The SERE between -3 D (diopters) and -5 D (p=0.035) revealed interference on the BPI. CONCLUSION: the BPI and the MPQ showed good psychometric properties regarding reliability and validity. The multidimensional questionnaires expanded the assessment of the PRK postoperative pain profile, compared to VAS, mainly in cognitive and affective aspects. The profiles of postoperative pain after PRK were similar between both eyes under the same conditions. In this study, a high SERE was the only predictor for increased pain after PRK

Fibromialgia é uma síndrome de etiologia desconhecida e caracterizada pela presença de dor difusa e crônica e pelo menos 11 dos 18 tender points específicos. É fundamental encontrar alternativas eficazes de tratamento que objetivem minimizar o impacto da fibromialgia (FM) sobre a qualidade de vida dos pacientes. O objetivo deste estudo foi avaliar a eficácia de um tratamento fisioterapêutico composto de terapia a laser nos tender points e exercícios de alongamento muscular sobre a qualidade de vida de pacientes com FM. Participaram do estudo 28 pacientes com FM que foram divididos em três grupos: GLA (n=10) que realizou 10 sessões de terapia a laser nos tender points e exercícios de alongamento; GA (n=10) que realizou 10 sessões de alongamento muscular e; GC (n=8) que realizou uma sessão educativa. Foram utilizadas as medidas da escala analógica visual da dor (VAS), dolorimetria dos tender points, Fibromyalgia Impact Questionnaire (FIQ) e SF-36. Os resultados mostraram que os grupos GLA e GA, quando comparadas as avaliações inicial e final, apresentaram diferença significante na VAS (p=0,006 e p=0,002; respectivamente); no limiar de dor dos tender points (p=0,001 e p=0,007; respectivamente); no FIQ (p=0,04 e p=0,006; respectivamente) e no SF-36 (p=0,001 e p=0,000; respectivamente). O grupo GC não apresentou diferença significante em nenhuma das medidas. Não houve diferença significante entre os grupos GLA e GA, mas houve diferença destes com o grupo GC nas medidas da VAS e do limiar de dor nos tender points. Neste estudo, conclui-se que os exercícios de alongamento são eficazes na melhora da dor, sensibilidade dolorosa dos tender points e qualidade de vida dos pacientes. Devem ser revistos alguns parâmetros da terapia a laser de baixa potência no tratamento desses pacientes, como o intervalo entre as sessões e o comprimento de onda do laser adotados. Sugere-se ainda que a abordagem educativa seja empregada como parte integrante do tratamento e que a relação fisioterapeuta-paciente deva ser valorizada, pois são aspectos importantes que podem contribuir para a melhora da qualidade de vida dos pacientes com FM. / Fibromyalgia is a syndrome of unknown etiology characterized by the presence of chronic and diffuse pain, and at least 11 of the 18 specific tender points. Its fundamental to find effective options of treatment that look for minimize the impact of fibromyalgia (FM) in the patients quality of life. The purpose of this study was to evaluate the efficacy of a physical therapy treatment compounded of laser therapy in the tender points and stretching exercises, in quality of life of patients with FM. Twenty-eight patients with FM participated of this study were divided in three groups: GLA (n=10) performed 10 sessions of laser therapy in the tender points and stretching exercises; GA (n=10) performed 10 sessions of stretching exercises and; GC (n=8) performed a single session of an educational approach. Measures of visual analogue scale of pain (VAS), dolorimetry of the tender points, Fibromyalgia Impact Questionnaire (FIQ) and SF-36 were assessed. The results showed, comparing initial and final assessments, the groups GLA and GA presented significant differences of VAS (p=0.006 and p=0.002; respectively); pain threshold of tender points (p=0.001 and p=0.007; respectively); FIQ (p=0.04 and p=0.006; respectively) and SF-36 (p=0.001 and p=0.000; respectively). There was no significant difference in any of the measures in the GC group. No significant groups GLA and GA differences were found, but compared with the controls (GC) the measures of VAS and pain threshold were significant different. In conclusion, in this study the stretching exercises were effective in the improvement to pain, tenderness threshold of the tender points and quality of life of patients with FM. Some parameters should be reviewed about low-power laser therapy in the treatment of patients with FM, as treatment intervals and laser wavelength. This study suggests that an educational approach could be employed as an integrant part of the treatment, and the relationship between physical therapist and patient plays an essential role in the treatment, since they are important aspects that contribute to the improvement in quality of life of patients with FM.

The aim of this thesis is to explore methods for assessing peer victimization and pedagogical leadership in school. The thesis includes four studies. Study I and II are based on web-based questionnaires among 2, 568 students in grades 7, 8 and 9. Study III is based on a questionnaire (n=128) and four focus group interviews (n=21) among students in grades 7 and 9. Study IV is based on a web-based questionnaire including 344 teachers. The results from Study I showed that among students who experienced peer victimization 13% were captured by a bullying measure, 44% by a measure of repeated peer aggression, and 43% by both measures, i.e. the two measures captured partly different pupils. Study II showed that the two measures captured the same proportion of adolescents with psychosomatic problems and showed no significant differences in mean values on the Psychosomatic Problems (PSP) scale. In Study III it was shown that besides the traditional criteria the adolescents definition of bullying also included a criterion based on the health consequences of bullying. That is, a single but hurtful or harmful incident could also be considered bullying irrespective of whether the traditional criteria were fulfilled or not. The Rasch analysis in Study IV indicated two sub dimensions of the Pedagogical and Social Climate (PESOC-PLP) scale; direct pedagogical leadership and indirect pedagogical leadership. Satisfying psychometric properties indicated that the PESOC-PLP scale could be used to measure pedagogical leadership of the principal. This thesis highlights problems with how bullying and school leadership is currently defined and measured. By strengthening the understanding of measurement methods of peer victimization and school leadership the aim is that the results from this thesis will contribute in providing a safe and positive school experience for children and adolescence and that it can be used as a valuable tool to combat peer victimization. / Baksidestext: The negative consequences of peer victimization on children and adolescents such as worsening academic achievement and mental ill health are major public health concerns which have been subjected to extensive research. However, there are long-standing concerns how to define, measure, and estimate prevalence rates of peer victimization and successful school leadership. The aim of this thesis is to study methods for assessing peer victimization and pedagogical leadership in school. The results show that excluding other forms of peer victimization than bullying have serious implications for the identification of victims and may underestimate the full impact of peer victimization on children. Further, the validation of the Pedagogical and Social Climate (PESOC-PLP) scale is a step towards ensuring valid assessments of pedagogical school leadership. By strengthening the understanding of measurement methods of peer victimization and school leadership the aim is that the results from this thesis will contribute in providing a safe and positive school experience for children and adolescence and that it can be used as a valuable tool to combat peer victimization.

The thesis is concerning rotator assembly at Indexator. A need to increase production has been seen and it can be done by implementing an optimized assembly process. In addition to the assembly process a new design on workstations and new test equipment is needed.The study resulted into three assembly process proposals. The processes were balanced, layouts were produced and Plant simulation was utilized to produce simulation models. Each proposal were analyzed based on cost, performance, ease of implementation, flexibility and worker condition. This resulted in a stationary assembly process being most promising and a 3D simulation model was produced for visualization and better understanding. The stationary assembly process has a capacity for 90 rotators per day, while reducing the amount of workers by one.The layout of the workstations was done based on the assembly process layout and further developed to make the work cell lean and ergonomic. It resulted in three workstations to perform the assembly. The test bench was developed by creating target specifications, establish a test procedure and decide components for the test bench layout. The finished test bench can measure dynamic torque, count particles to ensure cleanliness and is able to run the test unattended. / Examensarbetet handlar om montering av rotatorer på Indexator. Målet är att ta fram en optimerad monteringsprocess som kan implementeras i Indexators fabrik utan svårigheter. Den nya monteringsprocessen kommer kräva en ny design på arbetsstationerna och nya testbänkar.Fyra koncept på monteringsprocessen togs fram, baserat på monteringens behov och målsättning. Efter utvärdering så modifierades de fyra koncepten till tre förslag på monteringsprocesser. Processerna balancerades, layouter utvecklades och simuleringsmodeller producerades för varje process. Varje förslag analyserades baserat på kostnad, prestanda, implementation,flexibilitet och arbetar-förhållande. Resultatet blev en stationär monteringsprocess och en 3Dsimulering gjordes för visualisering och förståelse. Den stationära monteringsprocessen har en kapacitet på 90 rotatorer per dag och reducerar behovet av montörer.Layouten för monteringsstationerna baseras på processens layout och har modifierats för ergonomiska aspekter. Inom monteringsstationerna så utvecklades layouten för att minimera antalet onödiga rörelser för montören. Testriggens design utvecklades genom att analysera de behov som fanns, skapa en kravspecifikation samt utvärdera och besluta om testprocedur, upplägg för testrigg och dess ingående komponenter. Testriggen uppfyller målsättningen som är att kunna mäta dynamiskt vridmoment, räkna partiklar för att säkerställa renhet i rotatorn och kunna utföra testningen självgående för att frigöra montören under testprogrammet.

L'électronique de puissance et particulièrement les systèmes de conversions deviennent un enjeu majeur de la transition énergétique et de l'avenir des transports. Les contraintes technico-économiques liées aux nouvelles applications impliquent une augmentation des densités de puissance au sein des modules tout en limitant leur coût et en conservant une robustesse satisfaisante. Aujourd'hui, des solutions semblent émerger grâce à des structures innovantes associées aux composants grands gap et à l'intégration tridimensionnelle. Ces solutions apportent cependant un certain nombre de contraintes liées aux interconnexions électrothermomécaniques (ETM). L'augmentation des niveaux de température permis par les composants grands gap et l'attrait du refroidissement double face offert par les assemblages 3D augmentent de manière importante les contraintes thermomécaniques et causent des problèmes de fiabilité. C'est pourquoi de nouvelles interconnexions ETM sont développées pour s'adapter aux nouvelles contraintes et rendre possible ce saut technologique. Cependant les outils permettant la caractérisation thermique et électrique de ces nouvelles interconnexions restent à développer. Les travaux présentés dans ce mémoire se portent sur le développement et la mise au point d'outils de caractérisation des interconnexions dans des assemblages 3D. La difficulté d'obtenir la température du composant au sein du boîtier nous a poussé à explorer deux voies permettant d'estimer la température de jonction (TJ). Premièrement par l'implantation de capteurs de température et de tension au coeur d'un composant de puissance grâce la réalisation d'une puce de test spécifique. Et deuxièmement, par l'observation de la réponse en température de composants fonctionnels faisant appel à l'utilisation d'un paramètre électrique thermosensible (PTS) du composant. Les deux pistes explorées mettent à profit des solutions spécifiques innovantes pour permettre des caractérisations thermique et électrique fines des assemblages d'électronique de puissance. / Power electronic and particularly conversion systems are becoming a major challenge for the future of energetic and transport systems. Technical and economic constraints related to new applications lead to an increase of module power densities while reducing cost and maintaining a good robustness. Today, solutions seem to emerge from innovative structures associated to wide band-gap semiconductors and three-dimensional integration. These solutions lead to many constraints in electro-thermo-mechanical (ETM) interconnection field. Temperature level rises allowed by wide band-gap semiconductors and attractiveness of double sided cooling provide by the 3D assemblies have significantly increase thermo-mechanical stresses and cause reliability problems. This is why new ETM interconnections are developed to facing those difficulties and enable this technological gap. However, thermal and electrical interconnections characterization tools need to be develop. Works presented in this thesis focuses on the development of tools for new interconnections characterization adapted to 3D package. The difficulty of obtaining the temperature of the component within the package has led us to explore two ways to estimate the junction temperature (TJ). In a first hand we integrate temperature and voltage sensors inside a power component in a clean room process thanks to the achievement of a specific thermal test chip (TTC). And in a second hand, by observing the temperature response of functional components, using a temperature-sensitive electrical parameter (TSEP). The both paths explored take advantage of innovative specific solutions to allow precise thermal and electrical characterization of power electronic assemblies.

Kad sugebėtume efektyviai valdyti programinės įrangos kūrimą, mes turime sugebėti matuoti programinę įrangą. Alan Albrecht 1979 metais IBM korporacijoje pasiūlė naudoti funkcinių taškų analizės metodą. Šis metodas matuoja programinės įrangos naudotojui suteikiamą funkcionalumą ir yra nepriklausomas nuo naudojamų programinės įrangos kūrimo technologijų. Šiuo metu yra jau 5 standartizuoti funkcinių taškų analizės metodai, kurie naudoja skirtingas taisykles programinės įrangos dydžio matavimui. Šiame darbe yra apibrėžiami vertinimo kriterijai ir pagal juos lyginami standartizuoti IFPUG, Mark II, COSMIC, NESMA ir FiSMA funkcinių taškų analizės metodai. Lyginant metodus yra nagrinėjami jų koncepciniai panašumai ir skirtumai, standartizuotumas, industrinių duomenų prieinamumas, konvertuojamumas, tinkamiausia taikymo fazė, matavimo taisyklių subjektyvumas, nefunkcinių naudotojų reikalavimų vertinimas, sertifikavimo ir skaičiavimo vadovų prieinamumas, metodus palaikantys programiniai įrankiai bei metodų taikymo sritis. Analizės rezultatai parodo, kad šiuo metu geriausia yra pasirinkti IFPUG arba COSMIC metodus. / To effectively manage software development we must be able to measure software. Alan Albrecht in IBM Corporation in 1979 proposed the use of function point analysis method. This method measures functionality provided to the user by the software and is independent of the used software development technology. There are currently 5 standardized function point analysis methods, which use different rules for software size measurement. In this work estimation criteria are defined and used to compare standardized IFPUG, Mark II, COSMIC, NESMA and FiSMA function point analysis methods. During the comparison of methods their conceptual similarities and differences, standardization, availability of industry data, convertibility, the most suitable usage phase, subjectivity of measurement rules, estimation of non-functional user requirements, availability of certification and counting practices manuals, supporting software tools and the scope of methods applicability are examined. The analysis results show that the best choice is IFPUG or COSMIC methods.

Este trabalho prospectivo, duplo-cego randomizado, avaliou o efeito da analgesia preemptiva do cetoprofeno e do parecoxibe. Sessenta pacientes foram submetidos à cirurgia para remoção de terceiros molares inferiores bilaterais inclusos, sendo operado um lado de cada vez. O paciente foi seu próprio controle. Os pacientes foram separados em dois grupos de 30 pacientes. No grupo parecoxibe, na primeira operação foi usado o parecoxibe ou placebo, endovenoso, 30 minutos antes da cirurgia e imediatamente após a operação foi feita a administração do placebo ou parecoxibe, garantindo ao paciente receber parecoxibe antes ou após a operação. O lado oposto foi operado após duas semanas da primeira cirurgia e o paciente que havia recebido parecoxibe antes e placebo depois da operação recebeu placebo antes e parecoxibe depois da operação e o que havia recebido placebo antes e parecoxibe depois recebeu parecoxibe antes e placebo depois. Nos 30 pacientes do grupo cetoprofeno, o modelo foi o mesmo, substituindo-se apenas o parecoxibe pelo cetoprofeno. O paciente pôde utilizar como medicação resgate a dipirona, sempre que necessário para controlar a dor pós-operatória. Após a operação foi fornecido para todos os pacientes um questionário, contendo a escala analógica visual (EAV), a escala descritiva de dor (EDD) e uma tabela para informar o consumo de medicação resgate. Foi avaliada a dor pós-operatória por meio da EAV, da EDD e pelo consumo de medicação resgate. Não houve diferença estatisticamente relevante quanto a intensidade da dor com o uso do parecoxibe ou do cetoprofeno antes ou depois do procedimento cirúrgico. Ao comparar a analgesia proporcionada pelo cetoprofeno e pelo parecoxibe os resultados mostraram que o parecoxibe administrado antes do procedimento cirúrgico foi mais eficaz do que o cetoprofeno no controle da dor na quarta hora do pós-operatório (p=0,041), mas foi menos eficaz após 24h (p=0,003). Quando se comparou a analgesia proporcionada por esses fármacos usados após a operação, o parecoxibe foi mais eficaz do que o cetoprofeno após 6 e 8h do procedimento (p=0,003 e 0,023, respectivamente). / This is a prospective, double-blind randomized, cross over experiment, to evaluate the effect of the preemptive analgesia of ketoprofen and parecoxib. Sixity patients who had gone though surgery for removal of the impacted mandibular bilateral third molar teeth, having one side operated each time, were evaluated. The patients were separated in groups of 30, in the parecoxib group (P). On the first operation parecoxib or placebo were used 30 minutes before the surgery. Immediately after the operation, placebo or parecoxib were administred, so that the patient who had received parecoxib before the operation or after it. The opposite side was operated two weeks after the first surgery and the patients who received parecoxib before and placebo after operation received placebo before and parecoxib after operation and patients who received placebo before and parecoxib after received parecoxib before and placebo after, under the same method. In the group C (n= 30), the model was the same, using ketoprofen instead parecoxib. The patient could use dipyrone as rescue medication, in the event of postoperative pain. A questionnaire was provided to the patient after each surgery, containing a visual analogic scale, a descriptive pain scale and a table to inform the consum of rescue medication. The postoperative pain was evaluated by visual analogic scale, descriptive pain scale and rescue medicine consum. There was no statistically relevant difference as pain intensity with use of parecoxib or ketoprofen before or after the surgical procedure. Comparing ketoprofen analgesia against parecoxib analgesial, the results shown that the administration of parecoxib before the surgical procedure had a major efficacy than ketoprofen in pain control by the fourth hour post operatory (p=0,041), but was less efficient after 24 hours (p=0,003). When comparing the analgesic effect of both drugs after the operation, parecoxib was more effective than ketoprofen six and eight hours after the procedure (p=0,003 and 0,023, respectively).

O objetivo deste trabalho foi comparar aspectos clínicos de pacientes portadores de fibromialgia cujo início dos sintomas estivessem relacionados a eventos traumáticos e pacientes idiopáticos. Foram avaliados 135 pacientes por meio de um questionário estruturado sobre dados demográficos e situação de produtividade laboral, caracterização da dor e presença de queixas não relacionadas ao aparelho locomotor. Foi realizada contagem e dolorimetria de pressão dos pontos dolorosos e avaliação da dor segundo a escala visual analógica. O grupo de pacientes traumáticos conteve 48 pessoas apresentou maior período médio de escolaridade (8,1 &#177; 4,1 x 5,3 &#177; 2,9; p<0,001), maior contagem de pontos dolorosos (16,1 &#177; 2,8 x 15,0 &#177; 3,2; p = 0,047), menor período desde a generalização da dor (5,6 &#117; 6,9 x 4,1 &#177; 2,6 anos; p = 0,002) e maiores prevalências de dificuldade de concentração (83,0% x 65,1%; p = 0,048) e cólicas intestinais (45,8% x 26,4%; p = 0,036). Houve associação entre o trauma e a improdutividade econômica. Os demais aspetos clínicos não apresentaram diferença estatisticamente significante. Conclui-se que a etiologia traumática impõe poucas diferenças clínicas aos pacientes portadores de fibromialgia e não explicam o grau de incapacidade laboral que se observa. / The aim of this work was to compare clinical aspects of fibromyalgia patients whose onset was related to traumatic events to idiopathic patients. One hundred and thirty fice consecutive patients were interviewed with a structured questionnaire about demographic aspects, work disability, pain characterization and the presence of symptoms not related to the locomotor system. Tender point count and dolorimetry were performed, as well as pain evaluation according to the visual analogue scale. The group of traumatic patients counted with 48 individuals, and presented with longer period of formal education (8,1 &#117; 4,1 x 5,3 &#117; 2,9 years; p < 0,001), higher count of tender points (16,1 &#117; 2,8 x &#117; 3,2; p = 0,047), shorter period since generalization of pain (5,6 &#117; 6,9 x 4,1 &#117; 2,6 years; p = 0,002), smaller prevalences of concentration difficulties (83,0% x 65,1%; p = 0,048) and abdominal cramps(45,8% x 26,4%; p = 0,036). There was an association between trauma and work disability. Any of remaining clinical aspects presented with statistically significant differences. We conclude that trauma imposes few clinical differences to fibromyalgia patients and does not explain the degree of work disability which is observed among them.

O objetivo deste trabalho foi comparar aspectos clínicos de pacientes portadores de fibromialgia cujo início dos sintomas estivessem relacionados a eventos traumáticos e pacientes idiopáticos. Foram avaliados 135 pacientes por meio de um questionário estruturado sobre dados demográficos e situação de produtividade laboral, caracterização da dor e presença de queixas não relacionadas ao aparelho locomotor. Foi realizada contagem e dolorimetria de pressão dos pontos dolorosos e avaliação da dor segundo a escala visual analógica. O grupo de pacientes traumáticos conteve 48 pessoas apresentou maior período médio de escolaridade (8,1 &#177; 4,1 x 5,3 &#177; 2,9; p<0,001), maior contagem de pontos dolorosos (16,1 &#177; 2,8 x 15,0 &#177; 3,2; p = 0,047), menor período desde a generalização da dor (5,6 &#117; 6,9 x 4,1 &#177; 2,6 anos; p = 0,002) e maiores prevalências de dificuldade de concentração (83,0% x 65,1%; p = 0,048) e cólicas intestinais (45,8% x 26,4%; p = 0,036). Houve associação entre o trauma e a improdutividade econômica. Os demais aspetos clínicos não apresentaram diferença estatisticamente significante. Conclui-se que a etiologia traumática impõe poucas diferenças clínicas aos pacientes portadores de fibromialgia e não explicam o grau de incapacidade laboral que se observa. / The aim of this work was to compare clinical aspects of fibromyalgia patients whose onset was related to traumatic events to idiopathic patients. One hundred and thirty fice consecutive patients were interviewed with a structured questionnaire about demographic aspects, work disability, pain characterization and the presence of symptoms not related to the locomotor system. Tender point count and dolorimetry were performed, as well as pain evaluation according to the visual analogue scale. The group of traumatic patients counted with 48 individuals, and presented with longer period of formal education (8,1 &#117; 4,1 x 5,3 &#117; 2,9 years; p < 0,001), higher count of tender points (16,1 &#117; 2,8 x &#117; 3,2; p = 0,047), shorter period since generalization of pain (5,6 &#117; 6,9 x 4,1 &#117; 2,6 years; p = 0,002), smaller prevalences of concentration difficulties (83,0% x 65,1%; p = 0,048) and abdominal cramps(45,8% x 26,4%; p = 0,036). There was an association between trauma and work disability. Any of remaining clinical aspects presented with statistically significant differences. We conclude that trauma imposes few clinical differences to fibromyalgia patients and does not explain the degree of work disability which is observed among them.
