Effectiveness of Abdominal Breathing Exercise to Control Gastroesophageal Reflux Disease, a Randomized Controlled Trial
Abstract
Objectives: To determine the effect of actively training the crura of diaphragm which is a part of lower esophageal sphincter using abdominal breathing exercises to treat gastroesophageal reflux disease.
Methodology: With a randomized controlled study design, a total of 22 (11 in each group) clinically diagnosed patients of GERD presenting to the gastroenterology outpatient department at Holy Family Hospital in Pakistan were assessed using GERD related "quality of life index (QoLI)" questionnaire and their on-demand proton pump inhibitors (PPI) usage. Single blinding technique will be used. Patients ages 18-60 years with GERD were included. However, those with hiatal hernia > 2 cm, previous surgeries on LES and those with who could not undergo the breathing exercise training were excluded. The data was collected via interviews. The intervention group was trained to do a 5-min breathing exercise and advised to perform it 5 times a day for 4 continuous weeks. On demand PPI usage was self-recorded. The control group was also trained to perform a breathing exercise that had no effect on LES and was asked to self-record on demand PPI usage. After 4 weeks the data was collected from both groups and compared quality-of-life index and PPI usage. Data was retrieved and analyzed using SPSS version 22. Descriptive analysis was used for describing the study variables. Paired t-test was used for in group comparison before and after intervention and independent t test was used for between…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
