Overview
A pilot Study
To investigate the efficacy of a breathing intervention for improving persistent breathlessness due to dysregulated breathing following COVID-19 when compared to usual care.
Description
Pilot RCT for upto 60 subjects across 2 arms
Intervention A 12 session/six week, twice a week online group-based intervention based on breathing techniques including yoga practice directed by a specialist. Each group will aim for between 3- 6 participants.
Each online session will be circa 40-50 minutes in length. This will include an Introduction and warm up; Breathing practice including yogic breathing and a final cool down and relaxation.
Sessions will run at set times to ensure efficient use of resources but will try to accommodate different time points periods of the day when patients might be functioning best.
Comparator A six week non-intervention (usual care) period will be recruited to, allowing a comparison to the intervention.
