Outcome of Chair Aerobics & Pranayama on Anxiety and Exercise Tolerance in Coronary Artery Bypass Grafting Patients: Study Protocol of a Randomized Clinical Trial

Objectives: The current Indian scenario follows the western cardiac rehabilitation protocol; hence the primary aim of the study is to develop a cardiac rehabilitation phase 1 protocol for the Indian scenario. The protocol will be used in the study as standard rehabilitation protocol for the intervention groups. The literature suggests the use of Pranayama and chair aerobics to improve the anxiety in CABG patients. This study also aims to provide the answer for the effect of Pranayama and chair aerobics on anxiety and exercise tolerance in CABG patients. And also try to find out which among the two intervention is superior among one another. Methods: The cardiac rehabilitation protocol will be validated by experts in the field and applied in the patients and the results will be analysed. Then the protocol will be used as the standard rehabilitation protocol in both the groups. 100 patients will be randomised and allocated into 2 groups. Group 1 will receive Nadi Sodhana Chair aerobics for 15 minutes along with phase I cardiac rehabilitation. The group 2 will receive Chair aerobics for 15 minutes along with phase I cardiac rehabilitation. The outcome measures will be taken before the surgery and on the post-operative day 7. The primary outcome measures are Hospital anxiety and depression scale (HADS) and Heart rate and the secondary outcome measure is 6-minute walk test. The intention to treat analysis will be done after the data collection. Results: The data will be analysed using unpaired t test, p value <0.05 will be considered significant. Conclusion: The result will give a new insight into the field of cardiac surgery, where the effect of pranayama and chair aerobics on anxiety and functional outcome will be proved.
