Comparison of Thoracic Squeeze and Manual Diaphragmatic Release Technique in COPD Patients

The goal of this randomized control trial is to evaluate and compare the efficacy of two physiotherapy techniques-Thoracic Squeeze Technique (TST) and Manual Diaphragmatic Release Technique (MDRT)-on improving respiratory parameters, functional capacity, and quality of life in patients with mild to moderate Chronic Obstructive Pulmonary Disease (COPD). Objectives: * Assess the impact of TST and MDRT on respiratory parameters (FEV1, FVC, FEV1/FVC ratio, and chest expansion). * Compare the functional capacity outcomes of the two techniques using the 6-Minute Walk Test (6MWT). * Evaluate the effects of TST and MDRT on patient wellbeing and daily life through the COPD Assessment Test (CAT). Study Design: The study involves 34 participants, divided into two groups (n=17 each) via sealed envelope randomization. Both groups will receive their respective interventions (TST or MDRT) alongside a standardized pulmonary rehabilitation protocol (pursed-lip breathing, diaphragmatic breathing, active cycle of breathing, and endurance exercises). The intervention will be conducted three times per week for three weeks. Outcome Measures: Primary outcomes include respiratory parameters assessed through spirometry and chest expansion using a measuring tape. Secondary outcomes include functional capacity (6MWT) and patient wellbeing (CAT scores). Baseline and post-intervention measures will be analyzed using SPSS, employing Mixed ANOVA to determine interaction effects.
