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.

Detailed Description

Asthma is an inflammatory condition in which narrowing and swelling of the airways occur, accompanied with extra mucus production. This results in difficulty in breathing and triggers coughing, wheezing and dyspnea. In some cases asthma is a minor irritation, but on the other end of the spectrum it may interfered with activities of daily living and can even become life threatening in severe asthma attacks. According to a study conducted in Pakistan, the prevalence of asthma in adults was found to be 10.8% in adults, working in tanneries with 5.3% of them reporting their symptoms to be work related.

Non-pharmacological management of asthma includes patient education, guidance and physiotherapy. It is suggested that physical therapy may have positive effects in patients with asthma, as they possess dysfunctional breathing patterns accompanied with poor physical condition. Numerous reviews by Cochrane have been published in the recent years regarding the effects of physical therapy in patients with asthma, focusing on the effects of numerous techniques including Alexander technique, manual therapy, physical training, breathing exercises and inspiratory muscle training. In terms of specific effects of different physical therapy treatment techniques in patients with asthma, in light of the existing literature, breathing exercises have found to improve quality of life, reduce symptoms of anxiety, depression and hyperventilation, and decrease respiratory rate and medication use. Moreover, inspiratory muscle training is found to improve symptoms, decrease medication use and also improve inspiratory pressure.

Buteyko technique is a specialized breathing technique developed to reduce chronic hyperinflation.

A pre and post design quasi experimental study conducted was conducted in 2014 to determine the effects of Buteyko breathing technique on asthma control and QOL in school aged children with asthma where Buteyko breathing technique group showed significant improvements terms of asthma control and quality of life.

Based upon the review of the literature, evidence is inadequate in terms of comparison of Buteyko breathing technique with pursed lip breathing technique in the management of patients with asthma except for a single randomized controlled trial. For this reason the purpose of the current study is to compare the effects of Buteyko technique with pursed lip breathing in the management of patients with asthma.

Conditions

Asthma

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Buteyko group

Buteyko breathing exercises

Group Type: EXPERIMENTAL

Buteyko Breathing exercises

Intervention Type: 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.

Pursed lip breathing

Pursed lip breathing exercises

Group Type: ACTIVE_COMPARATOR

Pursed lip breathing

Intervention Type: 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.
