Comparative Effects of Buteyko Versus Pilates Breathing Combined With McKenzie Neck Exercises on Lung Function and Chest Expansion in Asthmatic Patients With Forward Head Posture

Asthma is characterized by airway inflammation and hyperinflation that flattens the diaphragm and increases reliance on accessory neck muscles. Chronic overuse shortens these muscles and promotes forward head posture (FHP), which in turn compromises rib-cage motion and respiratory mechanics. Correcting FHP alongside breathing retraining may therefore improve lung function and symptoms in asthma. This interventional, parallel-group study investigates the combined effects of McKenzie neck exercises with two different breathing approaches on lung function, chest expansion, posture, and quality of life in adults with asthma. Participants are allocated to two groups for a 4-week program: Group A performs McKenzie neck exercises plus Pilates-based breathing; Group B performs McKenzie neck exercises plus Buteyko breathing.
