RESUMO JUSTIFICATIVA E OBJETIVOS A dor lombar é a principal causa de incapacidade no Brasil. A maior parte da evidência sobre intervenções para dor lombar crônica (DLC) advém de países desenvolvidos. O objetivo deste estudo foi investigar a viabilidade de conduzir um programa baseado em exercícios e educação em dor na Atenção Primária à Saúde para adultos com DLC (versus lista de espera) e explorar o perfil dos pacientes que aderiram comparado aos que não aderiram à intervenção. MÉTODOS Este é um estudo de viabilidade. Foram incluídos adultos com DLC e residentes em Fortaleza, CE, no Brasil. O Grupo Intervenção foi composto por estratégias como exercícios físicos, educação em dor, ligações telefônicas e mensagens de suporte aos participantes. O Grupo Controle consistiu em lista de espera. Os desfechos primários incluíram taxas de retenção e adesão, entendimento da intervenção, credibilidade e satisfação com a intervenção. Os desfechos secundários incluíram fatores clínicos e demográficos, como intensidade de dor, incapacidade, prognóstico de recuperação e atividade física, descritos segundo comportamento de adesão. RESULTADOS Quarenta e cinco indivíduos foram alocados para o Grupo Intervenção e 24 para o Grupo Controle. Em geral, 57,8% dos participantes aderiram à intervenção. As taxas de retenção foram 53,33% e 58,3% para intervenção e controle, respectivamente. Os demais desfechos primários de viabilidade foram satisfatórios. Maior tempo sentado e o grau de instrução diferiam o perfil dos aderentes dos não aderentes à intervenção. Maior intensidade de dor e pior prognóstico de recuperação, mensurados na avaliação, influenciaram a não adesão aos exercícios domiciliares. CONCLUSÃO A viabilidade do protocolo apresentou-se adequada para entendimento dos componentes. Entretanto, a adesão ao protocolo e o seguimento dos participantes foram baixos. O perfil dos indivíduos aderentes à intervenção incluiu maior instrução e mais tempo sentado na sua avaliação inicial. Características como maior intensidade de dor e influência de fatores psicossociais influenciaram a não adesão aos exercícios domiciliares.

ABSTRACT BACKGROUND AND OBJECTIVES Low back pain is the leading cause of disability in Brazil. Most of the evidence on interventions for chronic low back pain (CLBP) comes from high income countries. The objective was to investigate the feasibility of conducting a program based in exercise and pain education in Primary Health Care supported by low-cost mobile technology for adults with CLBP (versus waiting list) and to explore the profile of patients who adhered compared to those who did not adhere. METHODS This is a feasibility study with adult residents of Fortaleza, Brazil with CLBP. The Intervention Group consisted of strategies such as physical exercises, pain education, phone calls and support messages to participants. The Control Group was based on a waiting list. Primary outcomes included retention and adherence rates, comprehension of the intervention, credibility, and satisfaction with the intervention. Secondary outcomes included clinical and demographic factors such as pain intensity, disability, recovery prognosis, and physical activity, described according to adherence behavior. RESULTS Forty-five individuals were allocated to the Intervention Group and 24 to the Control Group. Overall, 57.8% of participants adhered to the intervention. Retention rates were 53.33% and 58.3% for intervention and control, respectively. The other primary feasibility outcomes were satisfactory. Longer time spent sitting and level of schooling differed the profile of those who adhered to the intervention from those who did not. Higher pain intensity and poorer recovery prognosis, measured at baseline, influenced non-adherence to home exercises. CONCLUSION The feasibility of the protocol was adequate for the comprehension of the components, however, adherence to the protocol and the follow-up of the participants were low. The profile of individuals adhering to the intervention includes higher schooling and more time spent sitting at baseline. Characteristics such as higher pain intensity and the influence of psychosocial factors influenced non-adherence to home exercises. Brazilian Registry of Clinical Trials (REBEC RBR-5wqr2j).

Abstract Aim: Low back pain (LBP) is disabling in older adults. Although physical activity interventions positively affect LBP, older adults are underrepresented in the literature. We aim to investigate the feasibility of conducting a study to evaluate a primary care program of exercise therapy and pain education, supported by mobile technology, for older adults with chronic LBP (compared to best practice advice). Methods: In this parallel, two-arm randomized pilot trial, we will recruit adults aged 60 years and older with chronic LBP. The experimental group (Physical Activity supported by low-cost mobile technology for Back pain-PAT-Back) will consist of an 8-week group exercise program based on pain education, exercises, graded activities, and in-home physical activity. Text messages will be sent to promote adherence to home exercises. The control group will receive an evidence-based educational booklet given during one individual consultation. Outcomes will include recruitment rate, adherence and retention rates, level of understanding of the intervention content, perception of the utility of mobile technology, compliance with the accelerometer in a sub-sample of patients, and adverse events. Discussion: The results of this study will form the basis for a large randomized controlled trial. This innovative approach to managing LBP in the primary care setting for older adults, if proven to be effective, can bring an important advance in the knowledge of chronic LBP management to this population.

Abstract Background: Fibromyalgia syndrome (FMS) is both a challenging and disabling condition. The International Association for the Study of Pain (IASP) classifies FMS as chronic primary pain, and it can negatively impact individuals’ functioning including social, psychological, physical and work-related factors. Notably, while guidelines recommend a biopsychosocial approach for managing chronic pain conditions, FMS assessment remains clinical. The WHODAS 2.0 is a unified scale to measure disability in the light of the International Classification of Functioning, Disability and Health. Thus, this study aimed to evaluate the reliability and validity of the Brazilian version of WHODAS 2.0 for use in individuals with FMS. Methods: Methodological study of the validity and reliability of the Brazilian version of the 36-item WHODAS 2.0 with 110 individuals with FMS. The instrument gives a score from 0 to 100, the higher the value, the worse the level of functioning. We assessed participants with Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) (0–100), Fibromyalgia Impact Questionnaire (FIQ) (0–10) and Beck Depression Inventory instrument (BDI) (0–63). The construct validity, internal consistency, and test–retest stability. We used SF-36, FIQ and BDI to study construct validity analysis. For statistical analysis, we performed the intraclass correlation (ICC), Spearman correlation, and Cronbach's alpha, with a statistical level of 5%. Results: Most participants were female (92.27%), aged 45 (± 15) years. The test–retest reliability analysis (n = 50) showed stability of the instrument (ICC = 0.54; ρ = 0.84, p < 0.05). The test–retest correlation between the domains was moderate to strong (ρ > 0.58 and < 0.90). Internal consistency was satisfactory for total WHODAS 2.0 (0.91) and also for domains, ranging from 0.44 to 0.81. The construct validity showed satisfactory values with all moderately correlated with WHODAS 2.0 instruments (> 0.46 and < 0.64; p < 0.05). WHODAS 2.0 evaluates the functioning encompassing components of health-related quality of life, functional impact, and depressive symptoms in those with FMS. Conclusions: WHODAS 2.0 is a reliable and valid instrument to evaluate functioning of Brazilians with FMS. It provides reliable information on individuals’ health through of a multidimensional perspective, that allows for individual-centered care.

Resumo Este estudo transversal avaliou a associação de fatores biopsicossociais com a incapacidade em idosos com um novo episódio de dor lombar aguda. Foram incluídos idosos com um novo episódio de dor lombar aguda e excluídos aqueles com alterações cognitivas e deficiências motoras graves. A incapacidade foi avaliada pelo Roland Morris Disability Questionnaire. Os fatores biopsicossociais (variáveis clínicas, funcionais, estado de saúde, psicológicas e sociais) foram avaliados por um questionário estruturado multidimensional e exame físico. Regressão linear multivariada foi utilizada para análise dos dados com significância estatística de 0,05. Participaram 386 idosos com média de idade de 71,6 (±4,2) anos e incapacidade de 13,7 (±5,7) pontos. A análise de regressão linear multivariada identificou que pior saúde física e mental (avaliados através do SF-36), baixa autoeficácia em quedas, dificuldade para dormir por causa da dor, piores níveis de cinesiofobia, maiores índices de massa corporal, presença de rigidez matinal na coluna lombar, maior intensidade de dor, sexo feminino e pior mobilidade funcional foram significativamente associados com incapacidade (p < 0,05). Incapacidade relacionada à dor lombar está significativamente associada com piores condições biopsicossociais de saúde em idosos.

Abstract This cross-sectional study evaluated the association of biopsychosocial factors with disability in older adults with a new episode of acute low back pain. Older patients with a new episode of acute low back pain were included and those with cognitive alterations and severe motor impairment were excluded. Disability was assessed using the Roland Morris Disability Questionnaire. The biopsychosocial factors (clinical, functional, health status, psychological and social variables) were evaluated by a structured multidimensional questionnaire and physical examination. A multivariate linear regression was used to analyze data with a statistical significance of 0.05. A total of 386 older individuals with a mean age of 71.6 (± 4.2) years and disability of 13.7 (± 5.7) points were enrolled. Our regression analyses identified that worse physical and mental health (assessed through SF-36), low falls self-efficacy, trouble sleeping due to pain, worse kinesiophobia levels, higher body mass indexes, lumbar morning stiffness, increased pain intensity, female gender and worse functional mobility were significantly associated with baseline disability (p < 0.05). Low back pain-related disability is significantly associated with worse biopsychosocial health conditions in older adults.

Resumo Introdução: A cervicalgia crônica está associada a importantes gastos em saúde e à perda de produtividade no trabalho. Objetivo: Avaliar aspectos de dor e incapacidade de indivíduos com cervicalgia crônica. Métodos: Trinta e um voluntários com cervicalgia crônica, com média de idade de 29, 65 anos, foram avaliados por meio do questionário de dor de McGill em versão brasileira-Br-MPQ (Br-MPQ) e pelo Índice de Incapacidade Relacionada ao Pescoço (NDI). A análise do Br-MPQ foi realizada baseando-se nos valores numéricos associados com as palavras de descrição da experiência da dor (Pain Rating Index - PRI), e na intensidade da dor presente (Present Pain Index - PPI). O NDI foi utilizado para avaliar a interferência da cervicalgia pelos participantes no desempenho de tarefas cotidianas. Finalmente, foi investigada a associação entre o PPI e o NDI. Resultados: A dimensão mais significativa de dor no PRI foi sensorial (70%), e número de descritores escolhidos para descrevê-la foi 10 (2,62) em 20. O valor médio do PPI de 1,23 (0,76) em cinco pontos; 40% dos participantes descreveram a intensidade de dor como moderada. A pontuação do NDI foi de 9,77 (3,34), indicando incapacidade leve. Houve associação positiva entre intensidade de dor e incapacidade (r=0,36; p=0,046); mas não entre intensidade e duração da dor. Conclusão: Os resultados identificaram características importantes diante da experiência de pacientes com cervicalgia crônica e, além disso, a associação entre incapacidade e dor observada reforça a importância da abordagem destes itens de maneira complementar destes fatores para favorecer a funcionalidade destes pacientes.

Abstract Introduction: Chronic neck pain is associated with significant health costs and loss of productivity at work. Objective: to assess pain and disability in individuals with chronic neck pain. Methods: 31 volunteers with chronic neck pain, mean age 29, 65 years, were assessed using the McGill Pain Questionnaire in Brazilian version (Br-MPQ) and Neck Disability Index (NDI). The Br-MPQ analysis was performed based on the numerical values associated with the words selected to describe the experience of pain (Pain Rating Index - PRI), and present pain intensity (PPI). NDI was used to evaluate the influence of neck pain in performance of everyday tasks. Finally, we investigated the association between PPI and NDI. Results: PRI revealed that the most significant dimension was the sensory pain (70%), and the number of chosen words was 10 (2,62) out of 20 words. Mean PPI value was 1,23 (0,76) in five points; 40% of participants described pain intensity as moderate. NDI score was 9,77 (3,34), indicating mild disability. There was a positive association between disability and pain intensity (r = 0,36; p =0,046). Pain intensity and duration of pain were not associated. Conclusions: Findings of this study identified important information related to neck pain experienced by patients when suffering from chronic neck pain, moreover, the association between disability and pain intensity reinforces the importance of complementary investigation of these aspects to optimize function in them.

Abstract AIMS Physical activity levels could be related to chronic low back pain (LBP) in those who suffer from it; thus the purpose of this study was yo describe the physical activity levels in patients with chronic LBP, and to investigate whether physical activity levels are associated with LBP related disability and pain intensity in them. OBJECTIVES To describe the physical activity levels in patients with chronic LBP, and to investigate whether physical activity levels are associated with LBP related disability and pain intensity in them. METHODS This is a cross-sectional study with 36 patients with chronic LBP, both sexes, aged between 18 and 70 years. The main outcomes evaluated in this study were physical activity levels, LBP-related disability and pain intensity. RESULTS Participants were predominantly classified as active (53%) and irregularly active (42%). Mean pain intensity was 4.81 (± 2.72) points, while mean LBP-related disability was 13.19 (± 6.95). Physical activity and disability were negative and moderately correlated. CONCLUSION Physical activity and disability are inversely related, indicating that patients with chronic LBP that have lower physical activity levels had higher levels of disability.

O objetivo do estudo foi investigar a simetria postural e de distribuição de carga em crianças pré-escolares. A amostra foi composta de 67 crianças pré-escolares. Parâmetros posturais como: os alinhamentos horizontais da cabeça, do acrômio e das Espinhas Ilíacas Antero Superiores (EIAS), os ângulos entre os acrômios e as EIAS, frontal, Q, do joelho e do tornozelo e a assimetria horizontal da escápula em relação à T3 foram avaliados por fotogrametria. Baropodometria foi utilizada para identificar a distribuição da pressão plantar, enquanto o arco medial do pé foi analisado por fotografia. A mediana, o desvio padrão e a razão de simetria foram calculadas para cada parâmetro, sendo considerado simetria valores superiores a 90%. Correlação foi realizada entre os parâmetros analisados. Houve distribuição assimétrica para os parâmetros posturais e de distribuição de carga e uma correlação fraca e significativa entre a simetria da superfície e morfologia podal e entre a simetria da carga podal e do ângulo frontal do membro inferior. A presença de assimetrias, postural e de distribuição de carga observadas na primeira infância sugerem a importância de se monitorar os parâmetros posturais e de carga podal a longo prazo, a fim de prevenir alterações posturais e biomecânicas futuras

The aim of the study was to investigate the postural and load distribution symmetries in preschool children. The sample consisted of 67 preschool children with a median age of 54.00 ± 5.06 months. Postural parameters such as the horizontal alignment of the head, the acromion and Antero Superior Iliac Spines (ASIS), the angles between the acromial and ASIS, frontal, Q, knee and ankle and horizontal asymmetry of the scapula in relation to T3 were evaluated by photogrammetry. The baropodometry was used to identify the distribution of plantar pressure, while the medial arch of the foot was analyzed by photographic image. The median, standard deviation and the symmetry ratio were calculated for each parameter considered symmetry values greater than 90%. The Pearson’s or Spearman’s correlation were used between the parameters analyzed. There was asymmetric for postural and load distribution parameters for both genders and a null correlation between the symmetry of the surface and foot morphology and negative weak correlation significant between of the load foot and the front angle of the lower limb symmetries. The presence of asymmetries, postural and/or of load distribution, observed in early childhood suggest the importance of monitoring the postural and foot load parameters in the long term, preventing future postural and biomechanical alterations.
