Introduction: Chronic Obstructive Pulmonary Disease (COPD) is progressive disease and leading cause of morbidity and mortality world, especially in India. The abnormal inflammatory response develops an air flow limitation of the lungs which produces obstruction of mechanical function and the gas exchanging capability of the lungs. Various approaches like treadmill training, PNF techniques, rib cage mobilization have been employed to reduce dyspnea, increase chest expansion and expiratory flow rate.

Aim of the study: The aim of the study is to find out the effectiveness of treadmill training with chest Proprioceptive Neuromuscular facilitation versus treadmill training with rib cage mobilization on respiratory parameters among COPD subjects.

Methodology: 30 subjects were selected using convenient sampling method and randomly divided into two groups. Group A (n=15) received treadmill training with chest Proprioceptive Neuromuscular facilitation (PNF) and Group B (n=15) received treadmill training with rib cage mobilization for 3 days in a week for 2 months. The pre and post-test values were measured using Modified Borg’s scale for dyspnea, Inch tape for Chest expansion, and Peak Flow Meter for Peak Expiratory Flow Rate (PEFR).

Result: The intra group analysis showed statistically significant improvement in decreasing dyspnea ( t = 22.91), improves the chest expansion at axillary level (t = 14.36 ), xiphiod level ( t = 20.99) and peak expiratory flow rate ( t = 38.24) of treadmill training with rib cage mobilization group B than the treadmill training with chest Proprioceptive Neuromuscular facilitation group A at 5% level of significance. The inter group comparisons showed statistically significant differences in favour of group B.
