Effect of incentive breathing on lung functions in chronic obstructive pulmonary disease (COPD).

ABSTRACT

The effect of incentive breathing exercise was evaluated on patients of blue-bloater variety of chronic obstructive pulmonary disease (COPD) in a controlled study. The study used a device working on the principles of biofeed back for imparting breathing exercise. Exercise was given for half an hour daily for six weeks. There was significant increase in the vital capacity (VC) and reduction in air trapping in exercise group. There was remarkable improvement in subjective feeling of well being and breathlessness.
