Background and purpose of the study was to compare Pursed-lip breathing and Mouth taping for relieving dyspnoea and analyse their effectiveness. Method: Subjects of age group 18-34 years and normal BMI were randomly divided into two groups, group A (n= 40) for PLB technique and group B (n= 40) for MT technique. Each subject__ampersandsignrsquo;s Heart rate, Respiratory rate, Blood pressure, Treadmill walking time and level of dyspnoea according to Modified Borg CR10 scale was assessed before and after the intervention. Results: Both the techniques showed significant improvement by virtue of an increased treadmill walking time, the subject__ampersandsignrsquo;s dyspnoea status during the treadmill walking and lesser time for recovery to baseline vital parameters. Significant reduction in post-test RR after PLB (p=0.030) and MT (p=0.012) respectively were seen. Although, when compared to each other, MT and PLB techniques showed no significant differences with respect to the dyspnoea relieving time(p=0.08)and treadmill walking time(p=0.2). Conclusion: MT and PLB both have proved themselves to be equally effective in improving the response to exercise in terms of increased treadmill walking time and post-test dyspnoea status and recovery of vital parameters, without any significant differences between the two techniques.
