Background: This study was to determine whether the diaphragmatic breathing exercise using a DiP Belt(Diaphragmatic Pressure Belt) is effective in in- creasing the diaphragmatic motion and forced vital capacity.
Design: Pretest-Posttest design.
Methods: A total of 44 subjects(15 male, 29 female) participated in this study. All subjects were measured the diaphragmatic motion with a sonography and the Forced Vital Capacity(FVC) was measured with a digital spirometer. After 4 weeks, the subjects were intervened the diaphragmatic breathing exercise using a DiP belt and were remeasured for diaphragm motion and FVC.
Results: After exercise intervention, quiet breathing significantly increased with the change in dia- phragmatic motion and showed a moderate effect size (p<.01, Cohen's d = -0.53). In addition, it was sig- nificantly increased in deep breathing and showed a high effect size (p<.001, Cohen's d = -1.32). The mean diaphragmatic contraction pressure increased, but there was no significant difference and the peak diaphragmatic contraction pressure increased sig- nificantly (p<.05). Both diaphragmatic contraction pressure showed small effect sizes (respectively Cohen's d = -0.28, -0.33). In spirometry, FVC, Forced Expiratory Volume in 1 second (FEV1), and FEV1/FVC% all increased, but there was no sig- nificant difference. Only peak expiratory flow in- creased significantly and showed a small effect size (p<.05, Cohen's d = -0.41).
Conclusion: The DiP belt diaphragmatic breathing ex- ercise that the principle of visual feedback can correct diaphragm breathing in a short time, so it is a useful breathing exercise device that can help the diaphragm breathing exercise in the right way in clinical practice.
