RESUMO Objetivo: Investigar a confiabilidade, consistência interna e validade da versão em português do Brasil do University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ, Questionário sobre Falta de Ar da Universidade da Califórnia em San Diego) em pacientes com doença pulmonar intersticial (DPI). Métodos: Pacientes com DPI preencheram o questionário em três momentos distintos, com uma semana de intervalo entre as aplicações, com o auxílio de dois avaliadores independentes. A confiabilidade intra-avaliador e a interavaliadores foram analisadas por meio do coeficiente de correlação intraclasse (CCI). A consistência interna foi avaliada por meio do coeficiente alfa de Cronbach. Para a análise de validade, as associações entre as variáveis foram avaliadas por meio do coeficiente de correlação de Spearman ou de Pearson. Resultados: Trinta pacientes com DPI (fibrose pulmonar idiopática, fibrose pulmonar associada a doença do tecido conjuntivo, sarcoidose, asbestose ou pneumonia intersticial não específica) foram incluídos [15 homens; média de idade: 59 ± 10 anos; DLCO: 46 (33-64) % do previsto]. A pontuação no UCSD SOBQ apresentou excelente concordância e consistência interna na análise intra-avaliador [CCI: 0,93 (0,85-0,97); coeficiente alfa de Cronbach: 0,95] e na análise interavaliadores [CCI: 0,95 (0,89-0,97); coeficiente alfa de Cronbach: 0,95], bem como correlação significativa com a dispneia (avaliada pela escala do Medical Research Council; r = 0,56); com os domínios dor corporal, estado geral de saúde, vitalidade e capacidade funcional do Medical Outcomes Study 36-item Short-Form Health Survey (−0,40 ≤ r ≤ −0,74); com a distância percorrida no teste de caminhada de seis minutos (r = −0,38) e com a força muscular do quadríceps (r = −0,41). Conclusões: A versão em português do Brasil do UCSD SOBQ é válida, é confiável e apresenta consistência interna em pacientes com DPI no Brasil.

ABSTRACT Objective: To investigate the reliability, internal consistency and validity of the Brazilian Portuguese version of the University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ) in patients with interstitial lung disease (ILD). Methods: Patients with ILD completed the questionnaire at three different time points, one week apart, with the assistance of two independent assessors. Intra- and inter-rater reliability were analysed via the intraclass correlation coefficient (ICC). Internal consistency was assessed with the Cronbach’s alpha coefficient. For the validity analysis, associations between variables were assessed with Spearman’s or Pearson’s correlation coefficient. Results: Thirty patients with ILD (idiopathic pulmonary fibrosis, connective tissue disease-associated pulmonary fibrosis, sarcoidosis, asbestosis or non-specific interstitial pneumonia) were included (15 men; mean age, 59 ± 10 years; DLCO: 46 [33-64] % predicted). UCSD SOBQ scores showed excellent agreement and internal consistency in the intra-rater analysis (ICC: 0.93 [0.85-0.97]; Cronbach alpha: 0.95) and in the inter-rater analysis (ICC: 0.95 [0.89-0.97]; Cronbach alpha: 0.95), as well as correlating significantly with dyspnoea (as assessed by the Medical Research Council scale; r = 0.56); Medical Outcomes Study 36-item Short-Form Health Survey domains bodily pain, general health, vitality and physical functioning (−0.40 ≤ r ≤ −0.74); six-minute walk distance (r = −0.38); and quadriceps muscle strength (r = −0.41). Conclusions: The Brazilian Portuguese version of the UCSD SOBQ is valid, is reliable and has internal consistency in patients with ILD in Brazil.

Abstract Aim: Baropodometry is used to map pressure areas and plantar pressure oscillation, however, children’s evaluation reliability is not established. To establish the intra-rater and inter-rater reliability of baropodometry for analysis of plantar support and postural control (stabilometry) of children. Materials and Methods: Reliability study. The sample consisted of 112 healthy children of both sexes; aged 4 to 12 years old. For the baropodometer analysis, children were positioned in orthostatic position, bipodal support, with parallel and bare feet during four rounds of 15-second evaluations, executed by two independent evaluators. In order to establish the reliability of the results at different age ranges, participants were divided into two groups: children ages 7 years and younger (n = 44) and children aged 8 to 12 years old (n = 68). The variables analyzed were pressure area and maximum plantar pressure, area, and amplitude of oscillation of the center of pressure. Results: Reliability was rated from good to excellent for the intra- and inter-evaluators (ICC 0.81-0.86 and ICC 0.87-0.95, respectively) on plantar pressure variables, and poor to moderate for the center of pressure oscillations (ICC 0.33-0.55; ICC 0.47-0.57, intra and inter-evaluators, respectively). Conclusion: Excellent baropodometry reliability was observed when analyzing children’s plantar pressure at different age groups, and a single evaluation established reliable results. However, the stabilometry analysis with a baropodometer has poor reliability, and therefore, it should not be used for children aged 4 to 12 for postural control.

Resumo Introdução: A Síndrome da Dor Femoropatelar (SDFP) está relacionada à dor anterior do joelho, alteração de funcionalidade, déficits de equilíbrio e força muscular. Objetivo: Quantificar a dor, funcionalidade, força muscular do quadríceps (Q), glúteo médio (GM), rotadores externos de quadril (RE) e o equilíbrio em mulheres com SDFP. Métodos: Avaliou-se 20 voluntárias, sedentárias, entre 18 e 25 anos; divididas em grupo SDFP (N=10) e controle (N=10). Todas responderam a Escala Visual Analógica de Dor, Lysholm Knee Score Scale, Anterior Knee Pain Scale e Lower Extremity Functional Scale, realizaram a contração isométrica voluntária máxima dos músculos Q, GM e RE por meio de dinamometria e análise do equilíbrio postural pelo Star Excursion Balance Test (SEBT) e plataforma de força. Para análise estatística utilizou-se os testes Shapiro Wilk, Mann Whitney e Correlação de Spearmann, pelo SPSS® 20. Resultados: O grupo SDFP apresentou maior dor, incapacidade e velocidade média de oscilação do centro de pressão, entretanto não foram observadas diferenças para a força muscular de Q, GM e RE e equilíbrio analisado pelo SEBT. Estabeleceu-se correlação moderada entre SEBT e Centro de Oscilação de Pressão (COP) unipodal. Conclusão: Mulheres com SDFP apresentam maior dor, pior funcionalidade e alterações no equilíbrio corporal. A correlação moderada entre SEBT e o COP-unipodal aponta a possibilidade de uso deste teste funcional quando a plataforma de força não é acessível, o que facilita e destaca a importância do diagnóstico clínico do equilíbrio postural.

Abstract Introduction: Patellofemoral Pain Syndrome (PFPS) is associated with anterior knee pain, changes in functional capacity, balance and muscle strength disorders. Objective: To quantify pain, functional capacity, strength in quadriceps (Q), gluteus medium (GM), hip external rotator (ER) muscles and balance in sedentary women with PFPS. Methods: Twenty sedentary women, aged 18 to 25 years, were divided into two groups: PFPS (N=10) and control group (N=10). All the volunteers answered the items of the Visual Analogue Scale (VAS), the Lysholm Knee Score Scale, the Anterior Knee Pain Scale (AKPS), and the Lower Extremity Functional Scale (LEFS). The participants performed the following tests: maximal voluntary isometric contraction measured by dynamometry; postural balance using the Star Excursion Balance Test (SEBT) and a force platform. Statistical analyses were performed using the Shapiro Wilk test, the Mann Whitney U test and Spearman’s correlation coefficient. Data were submitted to SPSS 20 software. Results: The PFPS group presented greater pain, balance impairment and higher average velocity of oscillation; however, no differences were observed in Q, GM and RE muscle strength and in balance analyzed by SEBT. Conclusion: Women with PFPS exhibited greater pain, worse functional capacity and body balance. Moderate correlation between both balance tests suggests the use of SEBT when the force platform is not available, which could facilitate and highlight the importance of clinical diagnosis with regard to postural balance.
