Effect of Incentive Respiratory Training on Pulmonary Functions and Functional Capacity in Children With B-thalassemia Major

The study group was instructed to use an incentive spirometer, which should be held upright, sealed around the mouthpiece, and taken slowly and deep breaths. They will be motivated to achieve a preset volume through visual feedback. The child will hold their breath for 2-3 seconds at full inspiration and, after each set of 10 breaths, cough to clear mucus from the lungs. The exercise duration is 15 minutes.

The child will lie on their back, place one hand on their belly and one on their chest, and use a balloon or doll to fill both belly and chest up like a balloon. Inhale deeply, let the hands on the belly rise, then exhale slowly, making the belly down. The exercise will last for 10 minutes.

Sit in a seated position with crossed legs or knees. Inhale slowly through the nose for three seconds, then exhale through pursed lips, similar to blowing out birthday candles.

The study involves conducting Costal breathing exercises for children. The exercises involve placing hands on the apical region of the lung, turning the child's head, relaxing the shoulder and neck muscles, taking a deep breath, pushing the hand out, holding, and exhaling slowly. The hands provide pressure and resistance after initiation of inspiration, and the children rest for 2 minutes between exercises. The duration of the exercise varies between the control and study groups.
