Introduction: Respiratory muscle stretch gymnastics (RMSG) were developed to stretch the chest wall respiratory muscle during the contraction phase. We studied the immediate effect of RMSG and effect of 4 weeks of RMSG training in COPD patients. Methods:(1) Immediate effect of RMSG: Thity-four patients with COPD consecutively performed four RMSG patterns, four times each. The dyspnea rating on a 150-mm visual analog scale (VAS) was measured. (2) Effect of 4 weeks of RMSG training; 10 COPD patients (9 males, 1 female, age 71 ± 6 yrs; FEV_{1} 1.25 ± 0.70 L). The patients were instructed to perform 5 RMSG patterns, 4 times each, 3 times a day for 4 weeks. Six-minute walking distance (6MD) and pulmonary function tests were performed before and after 4 weeks of RMSG. Results: (1) The dyspnea rating on a 150-mm visual analog scale (VAS) was 11.6 ± 3.4 mm before RMSG and was significantly decreased to 6.2 ± 2.2 mm(p < 0.01) 5 minutes after RMSG. (2) 6MD was significantly increased from 330 ± 85 m to 378 ± 66 m(p < 0.01). The residual volume, functional residual capacity and total lung capacity (TLC) were all significantly decreased from 3.55 ± 1.03 L to 3.06 ± 0.79 L, 4.48 ± 1.12 L to 4.11 ± 0.92 L, and 6.26 ± 1.15 L to 5.87 ± 1.04 L(p < 0.02). The ratio of RV to TLC was significantly decreased from 56.4% to 52.1% (p < 0.01). Conclusions: These results suggest that RMSG is effective physical conditionning to improves pulmonary function and decreases dyspnea at rest and on exertion in COPD patients.
