Effects Of Breathing Exercises With And Without Aerobic Training On Dysfunctional Breathing And Exercise Intolerance In Patients With Postural Orthostatic Tachycardia Syndrome

Postural orthostatic tachycardia syndrome (POTS) is a chronic, multifactorial syndrome with complex symptoms of orthostatic intolerance. Of the major complaints are breathlessness and exercise intolerance. The aim is to explore the potential impact of a physiotherapy intervention involving education and breathing control on dysfunctional breathing and improving exercise intolerance in POTS. The study would be a randomised controlled trial. Duration would be 4 week. Patients will be randomly divided into two groups by lottery method. Data will be collected through questionnaire from enrolled subjects in physical therapy department of Liaqat Hospital, Lahore. Experimental group will be treated by Progressive Breathing Retraining Exercise Program-2 times a day for 15 minutes, initially Controlled Nasal Breathing with progressively increasing the Controlled Pause, 4 times a day for 15 minutes, then both techniques will be performed together. In addition to this Aerobic training will be assigned to both the groups. Aerobic training will include cycling and treadmill- for 30 minutes\day for 5 days\week for 1 month. Total 20 sessions. While the controlled group will receive only aerobic training which will include cycling and treadmill for 30 minutes\day for 5 days\week for 1 month. Total 20 sessions. The dysfunctional breathing and exercise intolerance will be assessed through Nijmegen Questionnaire and Veterans Questionnaire respectively at 0 week, after 2 week and after 4 week. The data will be analyzed by spss version 25.
