Effects of a Diaphragmatic Stretching on Pulmonary Function, Exercise Tolerance, and Quality of Life in COVID-19 Survivors
Coronavirus causes pneumonia and acute respiratory distress syndrome that leads to respiratory failure because of this covid patients require mechanical ventilation. The principal muscle used in inspiration is the diaphragm, which appears to be more affected by extended mechanical ventilation. Diaphragm inactivity during mechanical ventilation is the grave cause of diaphragm weakness
Objective: This study aimed to explore the effects of diaphragm stretching on pulmonary function, exercise tolerance, and quality of life in Covid survivors.
Methodology: In a single-blinded, quasi-experimental study, 59 subjects who recovered from Covid aged 35–60 were included. Spirometry, a 6-minute walk test, and a Shortform-8 questionnaire were used as outcome measures for pulmonary function, exercise tolerance, and quality of life. Participants received 18 treatments for three sessions for a total 6-week period. Outcome measures were taken following the first treatment session (Pre-1 and Post-1), after the ninth treatment session (Pre 9th and Post 9th), and after the 18th treatment session (Pre 18th and Post 18th). Data were analyzed by SPSS version 23.
Results: The result showed improvement in FVC, FEV1, and FEV1/FVC ratio with a significant p-value of 0.000 after diaphragmatic stretching in Covid survivors. Borg-scale mean with a significant p-value of 0.00, 6MWD mean with a significant p-value of 0.001, and SF-8 (MCS and PCS) mean with a significant p-value of 0.002 showed that diaphragmatic stretching improved pulmonary function, exercise tolerance and quality of life of covid survivors.
Conclusion: It concluded that diaphragmatic stretching helped in improving pulmonary function, exercise tolerance, and quality of life in Covid survivors.
