Giving continuation to the production of knowledge in nursing and seeking to contribute to the increase in the number of explanatory theories of the functional content of nurses, there is interest in answering the question: how can a middle-range theory in nursing be built that explains the nurse-elderly interaction in a successful aging process? As well, we address the goal of describing the process of building a middle-range theory in nursing. Middle-range theory refers to a qualitative paradigm study of inductive thinking, developed in the context of primary health care. The information was collected through participant observation and interviews. Method of analysis grounded theory by Corbin and Strauss(1) was followed, utilizing the triangulation of data and theoretical sampling.Grounded theory has become a method of analysis which facilitates the understanding and explanation of the phenomenon under study. By making clear the nature and process of the nurse-elderly interaction in the selected context and within the context of successful aging, a middle-range theory proposal emerged.

ResumoO objetivo deste estudo foi realizar uma revisão de literatura sobre as principais alterações que ocorrem no sistema respiratório após o Acidente Vascular Cerebral (AVC) e também sobre os efeitos de treino muscular respiratório nestes pacientes. A metodologia adotada foi a pesquisa de artigos através das bases de dados electrónicas (Pubmed, Scielo e Pedro) em língua portuguesa e inglesa relacionando os temas: alterações do sistema respiratório e métodos de avaliação e reabilitação da força muscular respiratória em indivíduos acometidos pelo AVC. Existe evidência científica de que indivíduos acometidos pelo AVC podem apresentar diminuição da força muscular inspiratória e expiratória. Estudos sugerem que o treino muscular respiratório, através de carga limiar, pode trazer benefícios quanto a melhora da função respiratória e da força dos músculos respiratórios. Porém, mais estudos devem ser realizados para o aprofundamento do conhecimento sobre os benefícios e efeitos a longo prazo da reabilitação respiratória em pacientes com AVC.
