The Effect of Respiratory Muscle Stretch Gymnastic (RMSG) on Pulmonary Function Test among Pregnant Ladies: An Experimental Study

Background: Respiratory function altered in pregnancy due to hormonal imbalances and size of uterus. With trimester progression, the relaxing position of diaphragm muscle moves 5 cm upward so the normal anatomy of chest will compromise. Because of these changes there is progressive decrease in lung volumes and capacities during pregnancy. So RMSG is Respiratory Muscle Stretch Gymnastic (RMSG) is the stretching exercise of respiratory muscle of chest wall. Aim: To find the effect of Respiratory Muscle Stretch Gymnastic (RMSG) on pulmonary function test among pregnant ladies. Objectives: 1) To find out the effect of RMSG on FEV1 in pregnant ladies. 2) To find out the effect of RMSG on FVC in pregnant ladies. 3) To find out the effect of RMSG on FEV1/FVC in pregnant ladies. Methodology: 60 subjects was taken according to the inclusion criteria. Then we assessed the subjects. Consent form was taken by the therapist as they have no any issue to participate in this study. Therapist divide subject in group of 30. There were be two group one was experimental and another was control group. Describe the procedure and protocol. Protocol was of 4 weeks and 7 days per week. The subjects were doing this according to the study duration. Before starting the procedure we were taken pre outcome measures. Subjects were performed the RMSG exercise. After completing protocol duration post outcomes were taken. Result and Discussion: Statistical analysis was done using SPSS version 20. Within the group pre and post data analysis was done using paired T test which shows significant improvement that is p value less than 0.05. In control group there is not that much significance because there is some improvement in FEV1 and FVC. In experimental group FEV1/FVC ratio goes high because there is more improvement in FEV1. Conclusion: In context to result and discussion, we do conclude from our study that 2nd and 3rd trimesters in pregnant women are prone to have diminished pulmonary function test- FEV1, FVC and FEV1/FVC ratio considering the anatomical changes, however, intervention of RMSG must be taken into consideration for pregnant women to maintain pulmonary function. However, cellular gaseous exchange at central as well as peripheral levels must be assessed to understand the physiological changes.
