简要总结
The goal for this clinical trial was to compare the effectiveness of Diaphragmatic Breathing and Pursed-Lip Expiration Exercises in improving lung functions {the Peak Expiratory Flow Rate (PEFR) and Forced Expiratory Volume in 1- second (FEV1)} and Chest Expansion in Egyptian outpatient adults with bronchial asthma.
The research questions were:
- Are Diaphragmatic Breathing Exercises effective in improving lung function parameters?
- Are Pursed-Lip Expiration Exercises effective in improving lung function parameters?
- Which of the two studied breathing exercise is more effective in improving lung function parameters?
All the participants were classified into 2 groups:
Group1:
Diaphragmatic Breathing Exercise training was offered for participants to complete the 8-weeks exercise program (each session lasted about 20 minutes twice daily for 5 days per week).
Group2:
Pursed Lip Breathing Exercise training was offered for participants to complete the 8-weeks exercise program (each session lasted about 20 minutes twice daily for 5 days per week).
The two main parameters which were assessed initially and after completion of the 2-month exercise program were:
- Lung functions {Peak Expiratory Flow Rate (PEFR) and Forced Expiratory Volume in 1-second (FEV1)}
- The chest expansion
详细描述
Participants were enrolled from Outpatient Chest Clinic in Ain Shams University Hospitals.
After checking for inclusion and exclusion criteria and signing the informed consent form the following was carried out.
After enrollment of the participants from outpatient chest clinic, their education and interviewing were conducted in a private comfortable room near to chest clinic taking the time for discussion, understanding the 2- month training program and practicing the exercises techniques through first visit, bimonthly visits and the last visit. These visits were the same for the two groups with a difference in the exercise technique (explained in detail in a separate paragraph for each group), these visits included:
A. First visit:
- Thorough history was carefully taken for proper assessment and exclusion of any patients prone to risks.
- Spirometry based- diagnosis was reviewed.
- Measurement of Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in 1-second (FEV1) and chest expansion. The techniques and steps of peak flowmeter and chest expansion measurements were explained for participants before assessing these parameters.
- The whole exercises technique was explained carefully and video demonstration on laptop was shown for participants to make sure of their understanding (See Appendix 1).
- Every participant practiced the exercise under supervision, and any mistakes were reviewed, and the exercise was repeated till mastering the technique.
- Encouragement of the participants for adherence to exercise program through:

研究组 & 干预措施
Diaphragmatic Breathing Exercise
Diaphragmatic Breathing Exercise training was offered for participants to complete the 8-weeks exercise program (each session lasted about 20 minutes twice daily for 5 days per week). Relaxation and comfortable positioning of the participant with full support to back and head and relaxation of the abdominal wall (fowler's position). One hand of the participant placed on the rectus abdominis muscle just inferior to the anterior costal margin and the other hand on chest wall keeping the shoulders relaxed and upper chest quiet during breathing in slowly and deeply through the nose following the abdomen to rise with subsequent slow expiration through pursed lip for three or four times then rest. Three or four sets were applied in 20 minutes exercising session.
干预措施: diaphragmatic breathing exercise (Behavioral)
pursed lip breathing exercise group
Pursed-Lip Expiration Exercise training was offered for participants to complete the 8-weeks exercise program (each session lasted about 20 minutes twice daily for 5 days per week). Closing the mouth while breathing in slowly through the nose for two counts while keeping shoulders and neck relaxed followed by expiration using pursued lips (as if they mimic whistling) for four counts. Three or four sets were applied in 20 minutes exercising session.
干预措施: pursed lip breathing exercise (Behavioral)
