Brief Summary

The objective of the study was to compare the effects of Buteyko breathing technique and pursed lip breathing technique in the management of asthma. A randomized controlled trial was conducted on 60 asthmatic patients randomly allocated to Buteyko technique group and pursed lip breathing group. Both the groups received 4 weeks of treatment, 3 times per week. Data was collected at base line, 2nd week and 4th week. Outcome measurements included FVC, FEV, PEFR and Asthma Control Test Questionnaire scores. Data analysis was carried out on Statistical Package for the Social Sciences (SPSS) v.21.0. Confidence interval was kept at 95% and a p-value of less than 0.05 was considered significant.

Outcome Measures

Primary Outcomes (5)

• Peak expiratory flow rate (PEFR)

  Peak expiratory flow rate (PEFR) measured through digital spirometer. Peak Expiratory Flow Rate (PEFR) measured through digital spirometer. Three zones of measurement are commonly used to interpret peak flow rates. Normal value of PEFR is (80-100%). Green zone indicates 80 to 100 percent of the usual or normal peak flow reading, yellow zone indicates 50 to 79 percent of the usual or normal peak flow readings, and red zone indicates less than 50 percent of the usual or normal peak flow readings.

  After 4 weeks of intervention

• Forced vital capacity (FVC)

  Forced vital capacity (FVC) measured through digital spirometer. If the value of FVC is within 80% of the reference value, the results are considered normal.

  After 4 weeks of intervention

• Forced expiratory volume in 1sec (FEV1)

  Forced expiratory volume in 1sec (FEV1) measured through digital spirometer. If the value of FEV1 is within 80% of the reference value, the results are considered normal.

  After 4 weeks of intervention

• FVC/FEV1

  FVC/FEV1 measured through digital spirometer. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65).

  After 4 weeks of intervention

• Asthma Control Questionnaire

  Asthma Control questionnaire is a self-reported subjective outcome measurement tool that is used to measure the sufficiency of asthma symptom control and changes in asthma symptoms. It is 5 point scale with scores ranging from 0 to 5 for each item. The greater the score of Asthma Control questionnaire, the better the prognosis and outcome.

Interventions

Buteyko Breathing exercises OTHER

Buteyko breathing technique was performed by asking the patient to take a small breath in and then out and hold his/her breath and count the time in seconds, as long as he or she can, until first signs of air hunger start to appear, followed by normal breathing once again. This procedure was repeated 15 times, three sets of 15 repetitions were given to the patient per day, 3 days per week and the treatment was continued for 4 weeks.

Buteyko group

Pursed lip breathing OTHER

Pursed lip breathing was performed as nasal inspiration followed by expiratory blowing against partially closed lips. Participants received a total of 3 sets of 15 repetitions per day, 3 times a week and the treatment was continued for 4 weeks.

Pursed lip breathing
