Effects of Functional Inspiratory Muscle Training on Pulmonary Function, Muscle Thickness, and Core Performance in Patients With Bronchiectasis

What this Trial Is About

Bronchiectasis is a chronic lung disease marked by recurring lung flare-ups, persistent cough, and mucus production. It causes permanent widening of the airways, leading to ongoing infection, inflammation, and lung damage. This condition varies widely among patients, with symptoms ranging from daily issues to occasional flare-ups. Researchers aim to study the effects of a specialized breathing muscle training called Functional Inspiratory Muscle Training (FIMT) in adults with bronchiectasis to improve lung function and overall health. The study compares two groups: one will perform 4 weeks of Inspiratory Muscle Training (IMT) followed by 4 weeks of FIMT using a breathing device, with sessions supervised both in person and online. The other group will complete 8 weeks of daily IMT with weekly face-to-face sessions and home practice monitored via messaging. Both groups use the POWERbreathe Classic Light Resistance device to strengthen respiratory muscles, with training intensity adjusted weekly based on maximal inspiratory pressure measurements. Participants will be involved for 8 weeks, undergoing various tests at the start and end of the intervention. These include lung function tests (like forced expiratory volume and capacity), muscle strength and thickness measurements, balance and endurance tests, a six-minute walk test, posture assessment, physical activity monitoring, and quality of life questionnaires. Researchers will also monitor treatment adherence and patient satisfaction throughout the study to evaluate the impact of these breathing exercises on adults with bronchiectasis.
