Purpose: To compare the immediate effect of “trunk flexion with pursed lip expiration (PLE)” and “trunk extension with sustained maximal inspiration (SMI)” in patients with chronic obstructive Pulmonary disease (COPD). The trunk exercises were modified from proprioceptive neuromuscular facilitation patterns. Methods: Thirteen patients with COPD participated in this study. They performed each type of exercise strategies for 20 min, in a randomized crossover design. The tidal breathing, forced expiratory spirometry, and breathlessness scale were measured before and immediately after exercise. Results: There were significant improvements in forced vital capacity (FVC), and breathlessness scale after trunk flexion with PLE. FVC increased from 2.20 ± 0.66 to 2.26: ± 0.70 L (p=0.038), Borg scale decreased from 3.8 ± 0.7 to 2.7 ± 0.6 (P ＜0.0001). A significant change of end expiratory volume (EEV) and tidal volume (TV) after trunk extension with SMI was also found. EEV increased from 1.54 ± 0.52 to 1.63 ± 0.52 L (p=0.0007), and TV increased from 0.77 ± 0.27 to 0.87 ± 0.31 L (p =0.0051). But no significant change of FVC and breathlessness was noted. Conclusion: These results suggest that trunk flexion with PLE might be a good exercise strategy to improve ventilation and relieve dyspnea in patients with COPD.
