Effects of respiratory muscle training in patients after cerebral vascular accident: a systematic review

Abstract

INTRODUCTION: Stroke is the result of the interruption of blood supply to the brain and can cause cellular damage and changes in neurological functions. These changes are relevant to the inefficiency of the oropharyngeal mechanisms of swallowing, breathing, phonation and protective reflexes of the lower airways culminating in a high incidence of aspiration pneumonia. Respiratory Muscle Training has the function of restoring muscle function that is compromised, training both strength and muscle endurance, better effectiveness in clearing the airways, conditioning and adapting to exercise and preventing respiratory muscle fatigue. OBJECTIVE: The aim of this study is to verify the effect of respiratory muscle training on individuals who have suffered a stroke. MATERIALS AND METHODS: This systematic review was carried out by searching the VHL databases (Scielo, Lilacs, IBECS, Medline), PubMed and analyzing the references. RESULTS: A total of 4834 studies were screened and analyzed, where 17 studies published between 2010 and 2019 were part of this review. CONCLUSION: Studies have shown that the use of TMR in post-stroke patients has positive effects on lung volumes and capacities, despite have a small sample size. The search for creating new studies that can assist in the prescription and standardization of the training of these individuals in different environments should be a way to think.
