Cultural adaptation and validation of the Brazilian Portuguese version of the PROactive Physical Activity in COPD-clinical visit instrument for individuals with COPD.

OBJECTIVE: To adapt the PROactive Physical Activity in COPD-clinical visit (C-PPAC) instrument to the cultural setting in Brazil and to determine the criterion validity, test-retest reliability agreement, and internal consistency of this version. METHODS: A protocol for cultural adaptation and validation was provided by the authors of the original instrument and, together with another guideline, was applied in a Portuguese-language version developed by a partner research group from Portugal. The adapted Brazilian Portuguese version was then cross-sectionally administered twice within a seven-day interval to 30 individuals with COPD (57% were men; mean age was 69 ± 6 years; and mean FEV1 was 53 ± 18% of predicted) to evaluate internal consistency and test-retest reliability. Participants also completed the International Physical Activity Questionnaire (IPAQ), the modified Medical Research Council scale, the COPD Assessment Test, and Saint George's Respiratory Questionnaire to evaluate criterion validity. RESULTS: The C-PPAC instrument showed good internal consistency and excellent test-retest reliability: "amount" domain = 0.87 (95% CI, 0.73-0.94) and "difficulty" domain = 0.90 (95% CI, 0.76-0.96). Bland & Altman plots, together with high Lin's concordance correlation coefficients, reinforced that agreement. Criterion validity showed moderate-to-strong correlations of the C-PPAC with all of the other instruments evaluated, especially with the IPAQ (rho = -0.63). CONCLUSIONS: The Brazilian Portuguese version of the C-PPAC is a reliable and valid instrument for evaluating the experience of Brazilian individuals with COPD with their physical activity in daily life.

RESUMO Objetivo: Adaptar o instrumento PROactive Physical Activity in COPD - clinical visit (C-PPAC) ao contexto cultural brasileiro e determinar a validade de critério, concordância da confiabilidade teste-reteste e consistência interna dessa versão. Métodos: Um protocolo de adaptação cultural e validação foi fornecido pelos autores do instrumento original e, juntamente com outra diretriz, foi aplicado em uma versão em português desenvolvida por um grupo de pesquisa parceiro de Portugal. A versão brasileira adaptada foi então aplicada transversalmente duas vezes, com intervalo de sete dias, em 30 indivíduos com DPOC (57% de homens; média de idade de 69 ± 6 anos; e média do VEF1 de 53 ± 18% do previsto) para avaliação da consistência interna e da confiabilidade teste-reteste. Os participantes também responderam ao International Physical Activity Questionnaire (IPAQ), à escala modificada do Medical Research Council, ao COPD Assessment Test e ao Saint George's Respiratory Questionnaire para avaliação da validade de critério. Resultados: O instrumento C-PPAC apresentou boa consistência interna e excelente confiabilidade teste-reteste: domínio "quantidade" = 0,87 (IC95%: 0,73-0,94) e domínio "dificuldade" = 0,90 (IC95%: 0,76-0,96). As disposições gráficas de Bland-Altman, juntamente com os altos coeficientes de correlação de concordância de Lin, reforçaram essa concordância. A validade de critério mostrou correlações moderadas a fortes do instrumento C-PPAC com todos os outros instrumentos avaliados, principalmente com o IPAQ (rho = −0,63). Conclusões: A versão brasileira do instrumento C-PPAC é uma ferramenta confiável e válida para avaliar a experiência de indivíduos brasileiros com DPOC em relação à sua atividade física na vida diária.

Current developments and future directions in respiratory physiotherapy.

Respiratory physiotherapists have a key role within the integrated care continuum of patients with respiratory diseases. The current narrative review highlights the profession's diversity, summarises the current evidence and practice, and addresses future research directions in respiratory physiotherapy. Herein, we describe an overview of the areas that respiratory physiotherapists can act in the integrated care of patients with respiratory diseases based on the Harmonised Education in Respiratory Medicine for European Specialists syllabus. In addition, we highlight areas in which further evidence needs to be gathered to confirm the effectiveness of respiratory therapy techniques. Where appropriate, we made recommendations for clinical practice based on current international guidelines.

Validation of the International Classification of Functioning, Disability and Health Core Set for obstructive pulmonary diseases in the perspective of adults with asthma.

Purpose: To validate the Comprehensive and Brief International Classification of Functioning, Disability and Health Core Sets for obstructive pulmonary diseases from the perspective of adults with asthma.Methods: This was a qualitative, cross-sectional study. Individual interviews with questions related to the disease and its impact on the patient's life were performed. The meaning condensation procedure was used for analysis.Results: Thirty-five participants (26 females, 41 ± 13 years old) were interviewed. A total of 405 concepts were identified, and 348 were associated to the components Body Functions (n = 168), Body Structures (n = 22), Activities and Participation (n = 33), Environmental Factors (n = 125). These concepts were linked to 61 categories: second level (n = 25), third level (n = 33), fourth level (n = 3), which confirmed 41% and 77% of those included in the Comprehensive and Brief Core Sets, respectively. Twenty-four additional categories were identified, and 57 concepts could not be linked to the classification.Conclusions: The International Classification of Functioning, Disability and Health Core Sets for obstructive pulmonary diseases were supported by the perspective of adults with asthma. The Brief version seemed the best reference for rehabilitation, reflecting the typical disabilities and impairments of these patients. Unconfirmed and added categories have been reported, and their analysis may assist future document updates.Implications for rehabilitationThe use of the International Classification of Functioning, Disability and Health Core Sets for Obstructive Pulmonary Diseases is relevant to guide patient assessment, treatment and monitoring.The concepts related to the Body functions and Environmental factors were the most relevant according to the perspective of adults with asthma.The Comprehensive and Brief International Classification of Functioning, Disability and Health Core Sets for Obstructive Pulmonary Diseases were supported by adults with asthma.
