Abstract Objectives Objective of the study was to examine the effects of Incentive Spirometry on cardiac autonomic functions in normal healthy subjects in 18–25 years age group. Material & Method 30 subjects (n=15 in Study group and n=15 in Control group) were included in this study. The duration of study was 3 months. Primary outcome measures included cardiac autonomic function tests. Outcome measures were recorded before and 3 months after the study. Result 3 months practice of Incentive Spirometry resulted in statistically significant change (p < 0.05) in following parameters - Basal heart rate, Immediate maximum heart rate, Steady state heart rate, Steady State heart rate (time in seconds) during heart rate response to Standing test; Minimum heart rate and Deep Breathing Difference (DBD) during heart rate response to Deep Breathing test. Conclusion 3 months practice of Incentive Spirometry changes autonomic function response. Top Keywords Breathing Exercise, Pranayama, Incentive Spirometer, Autonomic Functions. Top |
