Introduction: Although manual hyperinflation (MHI) is a physical therapy technique commonly used in intensive care and emergency units, there is little consensus about its use. Objective: To investigate the knowledge of physical therapists working in intensive care and emergency units about manual hyperinflation. Methods: Data were collected through self-administered questionnaires on manual hyperinflation. Data collection took place between September 2014 and January 2015, in Itabuna and Ilhéus, Bahia, Brazil. Results: The study sample was composed of 32 physical therapists who had between 4 months and 10 years working experience. All respondents affirmed that they used the technique in their professional practice. However, only 34.4% reported it to be a routine practice. 90.6% stated that the most common patient position during manual hyperinflation is “supine”. Participants were almost unanimous (93.8%) in citing secretion removal and cough stimulation as perceived benefits of MHI. High peak airway pressure was identified as being a precaution to treatment with MHI by 84.4% of participants, whilst 100% of the sample agreed that an undrained pneumothorax was a contraindication to MHI. Conclusion: The most common answers to the questionnaire were: supine position during MHI; secretion removal and cough stimulation as perceived benefits; high peak airway pressure as a precaution; and an undrained pneumothorax as a contraindication.

Pulmonary rehabilitation programs are part of the gold standard in the treatment of COPD, in this strategy are important: medical followup, engagement in physical activity and habit changes by patients. Among the objectives of these programs are to reduce symptoms, increase exercise tolerance, and increase functionalcapacity. 3 Despite the numerous proven benefits on the effectiveness of rehabilitation programs for patients with COPD, approximately 50% of them refuse to participate and about 30-50% leave the program before itsconclusion. 4 The aim of this study was to describe the main benefits achieved by including high-intensity physical training in pulmonary rehabilitation programs for patients with severe COPD. MethodsIt is an integrative review of the literature, a method that allows the survey and analysis of subsidies present in scientific literature, in a broad and systematic way. It is a method that aims to synthesize results obtained from research on a theme or issue, in an orderly and comprehensivemanner. 5 The elaboration of this study had six stages: (1) definition of the problem; (2) database search in virtual libraries (Pub Med, Virtual Health Library -Bireme, Scielo) by means of descriptors in Portuguese and their correspondents in English; (3) individual reading of texts pertinent to randomized clinical studies, with complete methodologies for critical analysis in relation to their adherence to the objective of this research; (4) tabulation of the main findings of selected studies;(5) interpretation of results and; (6) synthesis of knowledge.This study included only articles of the randomized clinical trial type, published between 2015 and 2020, that approached patients with moderate to severe COPD and that were available in full on the search platforms surveyed. The descriptors severe COPD, pulmonary rehabilitation and physical exercise were used for the Portuguese and English languages. Among the exclusion criteria were: review articles, publication of protocols, articles not published between 2015 and 2020, works that were not related to the subject of this research, that were not available in full, or that did not clearly describe their methods (Figure 1).

Introduction: Evidence-Based Practice (EBP) refers to the set of attitudes from which one can know and apply the best evidence, understand patients' preferences and use clinical experience to optimize care, as well as facilitate decision making by health teams. to prole physical therapy professionals as to their unde Objectives: rstanding and application of EBP in their clinical routines. Methods: this is a survey study involving 146 physiotherapists of both genders, from all Brazilian regions. The professionals were contacted exclusively by e-mail, through their respective regional professional councils, in order to receive the electronic questionnaires, prepared for this purpose using the Google Forms platform. The questionnaires were available for 90 days, after which they were no longer accepted. Results: 74.6% of the sample was female; there was almost unanimous agreement that EBP is necessary in clinical practice. Approximately 95% agreed that EBP can be applied even in high demand settings and 84.4% said they were able to insert the guidelines of practice guides into their clinical routines. However, it is noteworthy that 98.6% said they lacked the ability to search relevant scientic literature and the main reasons for not performing EBP were: lack of time, lack of ability to search relevant scientic literature and lack of ndings on a given patient population. the authors conclude that Brazilian physical therapists recognize the im Conclusion: portance of EBP as a guide for clinical decision making and that they use it in their professional routines, however, they need adequate orientation on efcient scientic searches in order to promote treatment excellence through reliable scientic materials.

Introduction: Physiotherapy through evidence-based practice (EBP) can enrich information about the history of the disease, conduct the examination, aid in therapeutic diagnosis, and guide appropriate intervention. Objectives: To describe the attitudes, knowledge and behaviors of students of the physiotherapy course regarding EBP, as well as the main barriers found for its full implementation. Methods: This is a survey study, carried out among students from the 7th semester of the physiotherapy course from all Brazilian macro-regions and duly enrolled in invited Higher Education Institutions (HEIs). Results: About 97% agreed that EBP is important in clinical practice, 31.94% said they did not receive formal training in EBP or received it partially during undergraduate studies, 87.5% said they have the ability for quality clinical research and 69.44% admitted to being able to incorporate practical guides to their learning and/or care. Among the main barriers pointed out for not performing EBP are insufficient time for scientific research, lack of information and lack of articles on the general population to which the patient belongs. Conclusion: The students considered the EBP an important tool in higher level learning and most of them both seek and apply knowledge present in relevant clinical research in their learning and/or care, although a considerable percentage never received formal training or read few articles per month. Among the barriers pointed to the achievement of EBP, the lack of skill for relevant scientific research and the lack of findings in the scientific literature for a certain population of patients, are factors that can be fully assisted by the higher education institution, thus culminating in the formation of a full professional and capable of providing a treatment of excellence.
