Inspiratory Muscle Training Potentiates the Beneficial Effects of Proportional Assisted Ventilation on Exertional Dyspnea and Exercise Tolerance in COPD: A Proof-of-Concept Randomized and Controlled Trial

This study aimed to investigate the effects of inspiratory muscle training (IMT) on inspiratory muscle strength, dyspnea, and quality of life (QOL) in COPD patients. A comprehensive search was undertaken on the Web of Science, Scopus, Embase, Cochrane, and PubMed databases, encompassing data published up to 31 March 2024. A meta-analysis was subsequently conducted to quantify the standardized mean difference (SMD) and 95% confidence interval (CI) for the effects of IMT in COPD patients. Sixteen studies met the inclusion criteria. IMT significantly improved inspiratory muscle strength (SMD, 0.86, p < 0.00001), dyspnea (SMD = −0.50, p < 0.00001), and QOL (SMD = 0.48, p = 0.0006). Subgroup analysis showed that <60% maximal inspiratory muscle pressure (PImax) IMT (inspiratory muscle strength, SMD = 1.22, p = 0.005; dyspnea, SMD = −0.92, p < 0.0001), IMT conducted for ≤20 min (inspiratory muscle strength, SMD = 0.97, p = 0.008; dyspnea, SMD = −0.63, p = 0.007; QOL, SMD = 1.66, p = 0.007), and IMT conducted >3 times per week (inspiratory muscle strength, SMD = 1.06, p < 0.00001; dyspnea, SMD = −0.54, p < 0.00001; QOL, SMD = 0.48, p = 0.0009) had greater effects. This meta-analysis provides clinicians with evidence supporting the recommendation that COPD patients engage in IMT at <60% PImax for more than 3 times per week, with each session lasting no more than 20 min, to improve inspiratory muscle strength, dyspnea, and QOL.

A Doença Obstrutiva Crônica Pulmonar (DPOC) é a terceira principal causa de morte no mundo, considerada uma patologia respiratória progressiva comum desencadeada por agentes, dentre eles o tabagismo e a exposição a substâncias tóxicas. O paciente com DPOC apresenta diminuição da força e da resistência muscular durante a inspiração, levando-o à menor tolerância ao esforço e afetando sua capacidade de realizar AVDs (Atividades de Vida Diárias). Dessa forma, torna-se importante a prática da fisioterapia respiratória e a realização da reabilitação pulmonar com o Treinamento Muscular Inspiratório (TMI), que vem sendo extremamente promissor na DPOC. Portanto, esta pesquisa objetiva identificar os benefícios do Treinamento Muscular Inspiratório na reabilitação pulmonar em pacientes com DPOC por meio de uma revisão integrativa de literatura, que concentrou as buscas nas bases de dados Cochrane; Ebsco Open Research; Medline; Pubmed e Scielo. Foram incluídos apenas ensaios clínicos publicados nos últimos 5 anos e idiomas inglês e português. Dos 2170 estudos encontrados apenas 8 estavam de acordo com o objetivo da presente revisão e neles foi possível identificar a diversidade dos programas de tratamento em relação à carga aplicada nos dispositivos de treinamento e à combinação com outras intervenções envolvendo o TMI. Diante disso, a pesquisa identificou que o TMI promove aumento da força e da resistência da musculatura respiratória, redução da dispneia e aumento da tolerância ao esforço em pacientes com DPOC, benefícios também potencializados quando associados a outras intervenções.
