Short term effects of respiratory muscle stretch gymnastics versus hold relax PNF on pulmonary functions and chest expansion in elderly individuals-a randomized clinical trial
Introduction: Respiratory muscle stretch gymnastics (RMSG) and hold relax PNF is effective in elder patients. RMSG is designed to stretch inspiratory muscle during inspiration and expiratory muscles during expiration. The upper chest wall intercostal muscles and back muscles consist of inspiratory muscles whereas the lower chest wall muscles consist of expiratory muscles. Hold relax PNF is for pectoral muscles to improve chest expansion and functional capacity. Methods: A randomized clinical trial, 40 subjects with age group above 60 years were randomized into two groups (group A and group B).Group A received RMSG and Group B received Hold relax PNF for 5 days. Outcome measures such as chest expansion at axillary xiphisternal level and pulmonary function test such as FEV1 and FVC were measured before and after five days of treatment. Results: Analysis by using independent “t” test between the group found that there is no statistically significant difference but by using dependent “t” test within the each group found that there is a statistically significant difference. Comparative analysis of pre intervention means shown that there is no statistically significant difference between the groups. Comparative analysis of post intervention mean shown that there is statistically significant difference in means of chest expansion only in Group A but there is no statistically significant difference in FEV1 and FVC between Group A and Group B. Conclusion: Present study concluded that five days of RMSG improved chest expansion in Group A whereas both the techniques showed significant improvement in chest expansion and pulmonary function within the groups.
