Overview
Brief Summary
To evaluate the extent to which a 12-week respiratory rehabilitation program consisting of inspiratory and expiratory breathing exercises compared to expiratory breathing exercises alone will help to improve shortness of breath, respiratory symptoms, breathing function, distance walked, and quality of life in those who are experiencing persistent shortness of breath after having had COVID-19. Measurements will take place at the beginning, 6 weeks, and at 12 weeks in the study.
Detailed Description
To evaluate the extent to which a 12-week respiratory rehabilitation program consisting of inspiratory and expiratory muscle strength training exercises as compared to a prior study of expiratory muscle strength training alone is effective in improving dyspnea, respiratory symptoms, quantitative measures of pulmonary function, physical performance, and quality of life in individuals reporting persistent dyspnea post-COVID-19 at baseline, six and twelve weeks.

Outcomes
Primary Outcomes
Modified Medical Research Council Scale
Time Frame: Baseline, 6-weeks, and 12-week measurements
Scale of 0-4 with 4 being the most severe dyspnea.
COPD Assessment Test
Time Frame: Baseline, 6-weeks, and 12-week measurements.
8-item questionnaire with a semantic, 6-point differential scale for each item. Scores range from 0-40 with higher scores indicating more severe respiratory symptoms.
EuroQoL-5 Dimension-5 Level
Time Frame: Baseline, 6-weeks, and 12-week measurements.
EuroQoL-5 Dimension-5 Level to evaluate 5 dimensions of quality of life including mobility, self-care, usual activities, discomfort and pain, anxiety, and depression. Each is scored using a 5-point semantic scale.
Forced Expiratory Volume over 1 second (FEV1)
Time Frame: Baseline, 6-weeks, and 12-week measurements
Using the Microlife Digital Peak Flow and FEV1 Meter (Clearwater, FL).
Peak Inspiratory Flow
Time Frame: Baseline, 6-weeks, and 12-week measurements.
Using the In-Check Peak Inspiratory Flow meter (Granbury, TX).
Thoracic Expansion Measures
Time Frame: Baseline, 6-weeks, and 12-week measurements
Gulick tape measure positioned around the participant's chest at the 4th intercostal space. Participant breathes in and out as far as possible and the difference between the 2 values equals thoracic expansion.
Physical Capacity
Time Frame: Baseline, 6-weeks, and 12-week measurements.
6 Minute Walk Test following the American Thoracic Society Procedure: 50-meter distance is marked. Participant walks as quickly as possible for 6 minutes. Results recorded in meters. Vital signs and oxygen saturation monitored and recorded.
Secondary Outcomes
- Feasibility and Acceptability of the Intervention(12-weeks.)
