The Effect of Pranayama Breathing Technique on Asthma Control, Pulmonary Function and Quality of Life
- Conditions
- Asthma
- Registration Number
- NCT04110951
- Lead Sponsor
- TC Erciyes University
- Brief Summary
Most of the asthma patients prefer complementary and integrative applications as they continue to experience asthma symptoms despite pharmacological treatment. Pranayama, one of these treatments, is a breathing-based technique and is a part of yoga, an ancient Indian science. This study was carried out as randomized controlled single blind study in order to analyze the effect of pranayama breathing technique applied to individuals suffering from asthma on asthma control, pulmonary functions and quality of life. The study comprised 50 patients in total, as 25 patients in pranayama group and 25 patients in control group. The approval of ethics committee, permissions from the institutions, and informed voluntary approval of the individuals were obtained to conduct the research. The data of the research were collected through the application of Asthma Control Test (ACT), Asthma Quality of Life Questionnaire (AQLQ), pulmonary function test (PFT), and patient observation chart. Pranayama breathing technique was applied to pranayama group 20 minutes once a day for four weeks, and relaxation technique was applied to relaxation group similarly in addition to standard treatment. ACT, AQLQ, and PFT were evaluated twice as before and after the one month of application process. Meanwhile, the patients' PEF measurements were followed with individual PEF meter on daily basis. The value of p\<0.05 was accepted statistically significant in the data analyses.

- Primary Outcome Measures
Name Time Method FEV1/FVC change from baseline score at the end of one month FEV1/FVC rate is an important final parameter in defining obstruction as there is not a great change observed in FVC values at early stages of the disease in most of the asthma patients.
Asthma Control Test change from baseline score at the end of one month Asthma Control Test (ACT) is composed of 5 main sections involving asthma influence level of patients due to daily actions of patients, frequency of asthma symptoms at daytimes and nights, need of urgent relaxing drug, and evaluation of disease by patients. Patients are required to respond each question with values between 1 and 5. Total score of these 5 questions ranges between 5 and 25
Forced Expiratory Volume First Second change from baseline score at the end of one month Forced expiratory volume in first second (FEV1), measured during breathing function test and a flow velocity, is the best indicator of obstruction in asthma. However, FEV1 reflects real obstruction only with powerful and maximum effort as it mostly related with effort.
Forced Vital Capacity change from baseline score at the end of one month Effort related part of forced vital capacity (FVC) reflects airways, pulmonary expriratory muscles and the situation of lung elastic recession power.
Asthma Quality of Life Questionnaire change from baseline score at the end of one month Standard Asthma Quality of Life Questionnaire (AQLQ) is a quality of life questionnaire specific to asthma comprising 32 questions. AQLQ was developed by Juniper et al. (1993) to use in clinical studies. The questionnaire evaluates responses through a 7 scores scale (1: severely impaired; 7: not impaired at all) based on changes in last two weeks regarding asthma. Standard AQLQ involves 12 questions about symptoms, 11 questions about activity limitation, 5 questions about emotional functions, and 4 questions about environment stimuli. Mean scores are calculated for subcategories and overall scores. The mean of obtained scores are evaluated between 1 and 7. The minimum score change clinically accepted important in the questionnaire is 0.50 and this situation is called "minimal significant difference" .
Peak Ekspiratuar Flow change from baseline score at the end of one month Peak Ekspiratuar Flow (PEF) measurement kind of test which can be accomplished through mobile hand-held tools that enable patients to follow their situations even at their own homes in asthma diagnose and treatment. Repeatability of the test is very high though its application is connected with effort. As PEF measurement gives information about big airways, lower values are obtained in comparison to FEV1 value at 30-50% of the patients. In PEF follow-up, the best PEF value of patient value is primarily defined. Because, the follow-up of patient is conducted in terms of his/her best value not in terms of prediction value indifferent to spirometer in PEF follow-up.
