RESUMEN
A artrite reumatoide (AR) é uma doença inflamatória crônica e multissistêmica de etiologia desconhecida e multifatorial. O processo inflamatório ocasionado pela AR pode causar manifestações extra-articulares e pode haver comprometimento pulmonar, com impactos significativos na morbidade e mortalidade. Deste modo, foi realizado um estudo de revisão com o objetivo de verificar se pacientes com AR apresentam déficit na capacidade e volume pulmonar, com busca nas seguintes bases de dados: Cinahl, Lilacs, Pedro e Pubmed, como também as bibliotecas online Scielo e Cochrane. Foram incluídos estudos realizados em população adulta maiores de 18 anos de ambos os sexos com diagnóstico clínico de AR. A busca forneceu inicialmente 967 artigos, dos quais 30 foram selecionados para a leitura completa, destes apenas sete foram incluídos. Realizou-se a extração dos dados e a avaliação da qualidade do estudo através da escala de Newcastle e Otawa. As alterações encontradas nos artigos são: distúrbios restritivos, obstrutivos e mistos, redução da capacidade de difusão de CO e aumento da relação volume residual/capacidade pulmonar total. Pacientes com AR possuem alteração na função pulmonar, principalmente das pequenas vias aéreas, não sendo possível compreender os mecanismos que desencadeiam essas modificações. Devido à escassez de estudos relacionados ao tema, tornam-se necessárias novas pesquisas. (AU)
Rheumatoid arthritis (RA) is a chronic inflammatory disease of unknown multisystem and multifactorial etiology. The inflammation caused by RA can cause extra articular manifestations and there may be pulmonary involvement, with significant impact on morbidity and mortality. Thus, we performed a systematic review in order to determine whether patients with RA have deficits in capacity and lung volume, with search in the following databases: Cinahl, Lilacs, Pedro and Pubmed, as well as online libraries Scielo and Cochrane. Studies conducted in adults over 18 years of both sexes with clinical diagnosis of RA were included. The search initially provided 967 articles, of which 30 were selected for full reading and only seven were included. We performed data extraction and quality assessment study by Newcastle and Otawa scale. The changes found in the articles are restrictive, obstructive and mixed disorders, reduced CO diffusing capacity, and residual volume/total lung capacity. RA patients have changes in lung function, especially of the small airways, and it is unclear the mechanisms that trigger these changes. Due to lack of studies related to the subject become necessary further research. (AU)

BACKGROUND AND PURPOSE: The prevalence of chronic low back pain (CLBP) is higher in older than in younger adults and is associated with poor postural control and falls. The objective of this study was to compare the postural control of younger and older subjects with and without CLBP during a one-leg stance. METHODS: Twenty subjects with and 20 subjects without nonspecific CLBP participated in the study. Each group contained 10 younger (50% males; mean age: 31 years) and 10 older adults (50% males; mean age 71 years). The subjects performed three 30-s trials of a one-leg stance on a force platform. Balance parameters were computed to quantify postural control, including center of pressure (COP) area, mean velocity, and mean frequency in the anteroposterior and mediolateral directions. RESULTS: Participants with CLBP presented significantly poorer balance (P < 0.05) than participants without CLBP. The effect size was large for younger adults (d = 1.44) and small for older adults (d = 0.40). Older adults with CLBP presented poorer balance than younger adults with CLBP (large effect size, d = 1.24). CONCLUSIONS: The findings indicate that CLBP affects the balance of both younger and older adults, and that the age-related changes also affect balance and modify the magnitude of CLBP effects on balance.
