This randomized controlled trial (RCT) investigates the efficacy of an abdominal binder as an adjunct to diaphragmatic breathing in 32 asthma patients (aged 18-60). Participants are allocated into two groups: the experimental group receives binder-assisted diaphragmatic breathing exercises (14 sessions/week for 4 weeks), while the control group performs conventional diaphragmatic breathing exercises. The study aims to evaluate improvements in respiratory mechanics, specifically focusing on reducing dyspnea, increasing breath-hold duration (control pause), and enhancing asthma-related quality of life. The intervention involves applying an external abdominal binder to provide resistance and tactile feedback during diaphragmatic breathing. Training intensity progresses from light resistance (weeks 1-2) to high resistance (weeks 3-4). The primary goal is to optimize diaphragmatic excursion and reduce the work of breathing associated with asthmatic hyperinflation.
