The purpose of this study: The pectoralis minor muscle, though being small and seemingly insignificant accessory muscle of respiration, it can play an important role in thoracic movement mechanics in patients with chronic obstructive pulmonary disease (COPD). Previous studies which investigated the effect of manual therapy in COPD patients did not include myofascial release for this muscle. Therefore, the purpose of this study was to determine acute effect of a single physiotherapy session of pectoralis minor myofascial release followed by strengthening exercises for scapular retractors and shoulder depressors on ventilatory function, chest expansion, and pectoralis minor muscle tightness pain in patients with chronic obstructive pulmonary disease (COPD).Subjects and methods: Fifty four patients with COPD were included in this study and were divided into two groups; Group (A) included 27 male patients, Group (B) included 27 male patients. Group A received one pectoralis minor myofascial release session plus strengthening of scapular retractors and shoulder depressors. Group B received a single bronchodilator inhaler therapy dose. Measurements of spirometry, chest expansion and verbal descriptor scale (VDS) of pectoralis minor muscle tightness pain were performed before and after the interventions. The spirometry measurements were forced expiratory volume in first second (FEV1), forced vital capacity (FVC), and maximum voluntary ventilation (MVV). Parametric statistics were used to analyze the data
