Inspiratory Muscle Training in Post COVID-19 Infection Subjects

Plain-language summary

Long-term COVID has been considered a clinical condition in which the patient, after the critical period of the disease, still has systemic symptoms such as muscle weakness, inability to exercise, sleep disorders and it is still unknown what happens to the pulmonary deposition process. of aerosols. In clinical practice, inspiratory muscle training has been used to treat these patients, but the effectiveness of this intervention in reducing these symptoms is still considered a gap in the literature. To evaluate the effectiveness of inspiratory muscle training in individuals who were affected by COVID-19 to improve submaximal aerobic capacity, respiratory muscle strength, sleep quality, pulmonary deposition of the inhaled radiopharmaceutical and quality of life. This is a quasi-experimental study. , in which elderly volunteers over 18 years of both sexes residing in the city of Recife-Pernambuco will participate. The sample will consist of individuals who have been affected by COVID-19, whose severity of the disease will be classified according to the criteria established by the study by Parasher (2020). 6 minutes. The pulmonary deposition of the radiopharmaceutical will be evaluated pulmonary function will be evaluated by scintigraphy while the maximum respiratory pressures will be evaluated by a manovacuometer. Subjective sleep assessment will be assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Daytime Sleepiness Scale (ESS) and objective measurement by actigraphy. Finally, quality of life will be measured by the generic Medical OutcomesStudy 36-Item Short-Form HealthSurvey (SF-36) questionnaire. In the group of post-COVID patients in which the reduction in endurance and inspiratory muscle power are identified, an inspiratory muscle training (IMT) will be performed with a load equivalent to 50% of the MIP (assessed weekly), for eight weeks.
