Virtual Reality Intervention Alleviates Dyspnea in Patients Recovering From COVID Pneumonia

"Participants wear a respiration belt (Vernier, Go Direct) that continuously transmits thoracic circumference readings to a mobile phone (Samsung Galaxy S8) in real-time. The mobile device is placed in a headset (Zeiss VR ONEPLUS) and used to create a stereoscopic, immersive scene in Virtual Reality. The data from the respiration belt is used to map the on-going respiration pattern onto a virtual body in the scene in one of two feedback conditions.~COVVR\_Synch provided synchronous feedback: participants receive real-time feedback of their respiration."
