Prevalence of fibromyalgia: literature review update / A prevalência de fibromialgia: atualização da revisão de literatura

ABSTRACT The present study aimed to update the literature review on the prevalence of fibromyalgia published in 2006. A bibliographical survey was carried out from 2005 to 2014 in the MEDLINE, Web of Science, Embase, LILACS and SciELO databases and 3274 records were identified. Five researchers selected the studies, following the inclusion criteria: studies that obtained the prevalence of fibromyalgia. Fibromyalgia studies in associated diseases were excluded. When screening by title and abstract, 2073 irrelevant articles were excluded. The full texts of 210 articles were evaluated for eligibility and this review included 39 studies, described in 41 articles. The selected studies were grouped into four categories: (A) prevalence of fibromyalgia in the general population; (B) prevalence of fibromyalgia in women; (C) prevalence of fibromyalgia in rural and urban areas; (D) prevalence of fibromyalgia in special populations. The literature shows values of fibromyalgia prevalence in the general population between 0.2 and 6.6%, in women between 2.4 and 6.8%, in urban areas between 0.7 and 11.4%, in rural areas between 0.1 and 5.2%, and in special populations values between 0.6 and 15%. This literature review update shows a significant increase in fibromyalgia prevalence studies in the world. The new 2010 American College of Rheumatology criteria have not been widely used yet and the COPCORD (Community-oriented program for control of Rheumatic Diseases) methodology has increased the quality of studies on the prevalence of rheumatic diseases in general.

RESUMO O presente estudo teve como objetivo atualizar a revisão de literatura sobre a prevalência da fibromialgia (FM) publicada em 2006. Foi feito levantamento bibliográfico do período de 2005 a 2014 nas bases de dados Medline, Web of Science, Embase, Lilacs e SciELO e identificaram-se 3.274 registros. Cinco pesquisadores selecionaram os estudos, de acordo com os critérios de inclusão: estudos que obtiveram a prevalência da FM. Foram excluídos estudos da FM em doenças. Na triagem pelo título e resumo, foram excluídos 2.073 artigos irrelevantes. Foram avaliados quanto à elegibilidade os textos completos de 210 artigos, incluíram-se nesta revisão 39 estudos, descritos em 41 artigos. Os estudos selecionados foram agrupados em quatro categorias: a) prevalência da FM na população em geral; b) prevalência da FM em mulheres; c) prevalência da FM em áreas rurais e urbanas; d) prevalência da FM em populações especiais. A literatura aponta valores de prevalência da FM na população em geral entre 0,2 e 6,6%, em mulheres entre 2,4 e 6,8%, nas áreas urbanas entre 0,7 e 11,4%, nas rurais entre 0,1 e 5,2% e em populações especiais entre 0,6 e 15%. Esta atualização de revisão de literatura mostra um aumento expressivo de estudos de prevalência da FM ao redor do mundo. Os novos critérios do Colégio Americano de Reumatologia de 2010 foram ainda pouco usados e a metodologia Copcord (Programa Orientado para a Comunidade para Controle de Doenças Reumáticas) aumentou a qualidade dos estudos de prevalência de doenças reumáticas em geral.

Prevalence of fibromyalgia: literature review update.

A bibliographical survey was carried out from 2005 to 2014 in the MEDLINE, Web of Science, Embase, LILACS and SciELO databases and 3274 records were identified.

Exercícios de alongamento e fortalecimento muscular no tratamento de pacientes com fibromialgia: um ensaio clínico randomizado / Stretching and strengthening exercises in treatment of fibromyalgia patients: a randomized clinical trial

Exercícios físicos são descritos como uma das formas mais eficazes de controle da Fibromialgia (FM). No entanto, os exercícios de fortalecimento e alongamento muscular ainda permanecem pouco avaliados. Objetivos: Avaliar e comparar a eficácia dos exercícios de alongamento e fortalecimento muscular, isolados, na melhora da força muscular, flexibilidade, dor, sintomas e qualidade de vida de pacientes com FM, comparando com um grupo controle. Casuística e métodos: A amostra foi composta por 79 mulheres elegíveis das quais 16 foram excluídas e 63 iniciam o estudo, sendo alocadas aleatoriamente em três grupos: alongamento (GA), fortalecimento (GF) e controle (GC). Ao final, 14 finalizaram o tratamento no GA, 16 no GF e 14 no GC. Todos os sujeitos foram avaliados antes e após 12 semanas, da seguinte forma: força muscular de flexores e extensores de joelho pela contração isométrica voluntária máxima (CIVM) com célula de carga (EMG System do Brasil); flexibilidade pelo teste do 3º dedo-solo (3DS); dor pela escala visual analógica (EVA); limiar de dor nos tender points (LD) e número de tender points positivos (TP+) com dolorímetro de Fischer; sintomas da FM pelo Questionário de Impacto da FM (QIF) e qualidade de vida pelo Medical Outcomes Study 36-item Short-Form Health Survey (SF- 36). O GA e o GF realizaram exercícios gerais, envolvendo a musculatura de membros superiores, inferiores e tronco, com freqüência de bissemanal. Os dados foram analisados pelos testes estatísticos: t-Student, Wilcoxon, Anova um fator e Kruskal- Wallis, com nível de significância de 5%. Resultados: O GA teve melhora estatisticamente significante nas variáveis: LD, 3DS; fadiga, sono e rigidez do QIF; capacidade funcional, Vitalidade, saúde mental, dor e total físico e emocional do SF-36 (p=0,05) e, o GF nos itens: LD, TP+, 3DS, CIVM flexão de joelho; fadiga, sono, rigidez, ansiedade, depressão e escore total do QIF; capacidade funcional, vitalidade, saúde mental e total emocional...

Exercises have been reported as one of the most effective management of Fibromyalgia (FM), however stretching and strengthening training remain under evaluated. Objectives: To assess and compare the effects of stretching and strengthening exercises on muscle strength, flexibility, pain, symptoms and quality of life of FM patients, comparing to a control group. Methods: The sample was composed by 79 eligible women of whom 16 were excluded, and 63 entered the study and were randomly assign in to one of three groups: flexibility group (FG), strength group (SG) and control (CG). At the end, 14 finished the study on FG, 16 on ST and 14 on CG. All subjects were evaluated before and after 12 weeks according to the following procedures: maximum isometric muscle contraction for knee flexion and extension (MIMC) using the EMG System do Brasil dynamometer, flexibility by finger-to-tip floor test (FTF), pain by visual analogue scale (VAS), pain threshold (PT) and tender points count (TP+) by a Fischer dolorimeter, symptoms by Fibromyalgia Impact Questionnaire (FIQ) and quality of life by Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). FG and SG underwent in a stretching and strengthening program, respectively, including exercises for upper and lower body and trunk, twice a week. Data were statistically analyzed by: t-Student test, Wilcoxon test, Anova one-way and Kruskall- Wallis Anova, with significance level of 5%. Main Results: FG had statistically improvements after treatment in: PT, FTF, fatigue, sleep and stiffness of FIQ; functional capacity, vitality, mental health, pain and role physical of SF-36 (p=0,05). SG had statistically improvements after treatment in: PT, TP+, FTF, MIMC of knee flexion, fatigue, sleep, stiffness, anxiety, depression and total score of FIQ and functional capacity, vitality, mental health and role emotional (p=0,05). No significant difference was observed in CG after 12 weeks (p=0,05). Comparing three groups...
