Efectividad de la respiración glosofaríngea en pacientes con enfermedades neuromusculares y lesión medular: Revisión sistemática exploratoria

Abstract

BackgroundNeuromuscular diseases and spinal cord injuries compromise respiratory muscles and lung function, causing respiratory complications. Acute respiratory failure and chronic respiratory compromise cause high risk of morbidity and mortality. The use of glossopharyngeal respiration has been described to improve pulmonary and respiratory muscle function variables that promote more effective coughing and increased time off mechanical ventilation. ObjectiveDescribe and present the current evidence of the effectiveness of glossopharyngeal respiration in improving lung and respiratory muscle function in adult and pediatric patients with neuromuscular diseases or spinal cord injury with or without mechanical ventilation. DesignExploratory review with the PRISMA-ScR methodology. A search was carried out in the PEDro, Web of Science, Scopus, PubMed, ScienceDirect, Springer, Medline, Cochrane, SciELO, Lilacs, Google Academic databases, keywords and MeSH terms were used in Spanish, English and Portuguese languages, among the years 2000–2020. The results are presented in a descriptive way. Results491 studies were identified and 12 were included. 58.3% were conducted in European countries. 41.6% of the studies were critically appraised and none fully met the quality criteria. The effectiveness of glossopharyngeal breathing in lung and respiratory muscle function was related to an improvement in vital capacity in 66.6% and peak cough flow in 33.3% of the studies. Improvement in thoracic expansion was reported in 66.6% of the studies and complications such as syncope, dizziness in 33.3%. ConclusionThe effectiveness of glossopharyngeal respiration in patients with neuromuscular diseases and spinal cord injury is related to increased vital capacity and peak flow of cough. Studies with more scientific rigor are recommended to support the validity of these results.
