Abstract

Chronic obstructive pulmonary disease (COPD) causes the respiratory muscles and muscles around the chest to lose their elasticity, become shortened, and weakened, leading to respiratory dysfunction. Stretching and superficial heat therapy increase flexibility and reduce muscle contraction. However, its effects in COPD patients are limited. This pilot study is an experimental study, aims to investigate the immediate and short-term effects of hot pack combined with respiratory muscle stretching on chest expansion and respiratory muscle strength in COPD patients. Fourteen male participants with moderate-stable COPD were applied hot pack to the upper back and chest for 20 minutes, followed by respiratory muscle stretching. Chest expansion was measured with a tape measure, and respiratory muscle strength was measured with a respiratory pressure meter before the experiment and at 0, 30, and 60 minutes after the intervention. The results showed that chest expansion and maximal inspiratory and expiratory pressure, significantly increased after the intervention compared to before the intervention (p<0.05), with the greatest increase occurring at 30 minutes, except for the middle chest expansion, which continued to increase until 60 minutes. These findings suggested that the combination of hot pack and respiratory muscle stretching improves chest expansion and respiratory muscle strength in COPD patients immediately, with effects lasting for over 30 minutes.
