Validation of the Brazilian Portuguese version of the University of California San Diego Shortness of Breath Questionnaire in patients with interstitial lung disease.

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.

Functional performance tests in interstitial lung disease: Impairment and measurement properties.

BACKGROUND: There is limited information regarding impairment in functional performance tests and their measurement properties in ILD. The present study aimed to verify the impairment and measurement properties of functional performance tests in ILD. METHODS: ILD and healthy individuals underwent assessments of pulmonary function, peripheral muscle strength (handgrip force and maximum isometric contraction of quadriceps femoris - MIVCq) and exercise capacity (6-min walk test - 6MWT). Functional performance was assessed by timed-up-and-go with usual (TUGu) and fast (TUGf) gait speeds, 4-m gait speed (4MGS), sit-to-stand in 30 s (30sec-STS), 1 min (1min-STS) and with 5 repetition (5rep-STS) and Short Physical Performance Battery (SPPB). Functional performance was compared between groups, validity (correlation with 6MWT and MIVCq) and reliability of tests were checked in subjects with ILD (intra- and inter-rater agreement analysis). RESULTS: Seventy-six participants (40 ILD [25 women, 61 ± 11 years, FVC 75 ± 17 %pred] and 36 healthy [22 women, 61 ± 9 years, FVC 97 ± 11 %pred]) were included. Functional performance in ILD was worse than in healthy individuals in all tests, except for the 30sec-STS (p = 0.13). Pre-specified validity criteria were reached for TUGu, TUGf, 4MGS and 5rep-STS (-0.69 < r < 0.55; p < 0.05 for all). Except for 4MGS and SPPB, all tests showed good to excellent inter-rater (0.85 < ICC<0.93; p < 0.05 for all) and all tests showed good to excellent intra-rater (0.83 < ICC< 0.94; p < 0.05 for all) reliability. CONCLUSIONS: Subjects with ILD present worse functional performance than healthy individuals. According to reliability and validity results, TUGu, TUGf and 5rep-STS seem to be the most appropriate tests to evaluate functional performance in ILD.

Treinamento isodinâmico em UBS melhora qualidade de vida e capacidade funcional de mulheres / Isodynamic training in a BHU improves quality of life and functional capacity of women

Objetivo: Avaliar e comparar os efeitos do treinamento isodinâmico na capacidade funcional e qualidade de vida de mulheres com fatores de risco cardiovasculares cadastradas em uma Unidade Básica de Saúde. Métodos: Participaram 26 pacientes subdivididas em dois grupos: grupo controle (n=13), não praticantes de exercícios físicos regulares, e grupo treinamento (n=13), voluntárias que realizaram o treinamento isodinâmico. Este treino (caminhada associada a exercícios de diagonal de membros superiores com peso de 1 kg e elástico) obteve frequência de três sessões/semana com duração de uma hora. A capacidade funcional foi avaliada pelo teste de caminhada de seis minutos, e a qualidade de vida pelo SF-36. Resultados: As componentes do grupo treinamento apresentaram melhor capacidade funcional e obtiveram qualidade de vida superior às do controle. Conclusão: O treinamento isodinâmico mostrou-se uma conduta adequada, simples e de baixo custo em bairros periféricos como medida de prevenção e proteção a saúde.

Objective: To evaluate and compare the effects of isodynamic training on functional capacity and quality of life of women with cardiovascular risk factors registered at Basic Health Unit (BHU). Methods: The study included 26 women divided into two groups: a control group (n=13) of women who did not exercise regularly, and a training group (n=13), whose members performed isodynamic training (walking exercise associated with upper limb exercise performed in diagonals with 1 kg weight and elastic tubing) in a frequency of three sessions / week for an hour each. Results: Women in the training group had better functional capacity and an improved quality of life compared with the participants in the control group. Conclusion: The isodynamic training proved to be a simple, low-cost measure for health prevention and protection in suburban areas.
