NCT04898205

Brief Summary

This study will test the efficacy of treadmill exercise combined with supplemental oxygen during exercise and recovery for the treatment of persistent post-acute COVID-19 symptoms. Participants will be pseudo-randomized (stratified by age) to one of four conditions for 8 treatment sessions: 1) treadmill exercise plus supplemental oxygen, 2) treadmill exercise plus air, 3) supplemental oxygen only, 4) air only. All participants will then cross-over and receive 16 additional sessions of treadmill exercise plus supplemental oxygen.

Outcome Measures

Primary Outcomes (8)

  • Heart rate and rhythm response to exercise and positional changes

    Heart rate and rhythm will be measured using 3-lead ECG telemetry

    Up to 24-weeks

  • Blood pressure response to exercise and positional changes

    Blood pressure will be measured via manual cuff

    Up to 24-weeks

  • Activity metabolic equivalent of task (MET) tolerated

    MET will be computed based upon peak exercise speed (MPH) and incline % gradation). Scores are expected to range from 1.8 to 12.1 (but can be higher is speed exceeds 3.9 MPH). Higher METs indicate more energy output.

    Up to 24-weeks

  • Breathlessness

    Breathlessness will be assessed during peak exercise via self-report using the Borg Dyspnea scale. Scores can range from 0 to 20 and higher scores indicate more breathlessness

    Up to 24-weeks

  • Rate of perceived exertion (RPE)

    RPE will be assessed during peak exercise via self-report using the Borg RPE scale. Scores can range from 0 to 20 and higher scores indicate more RPE.

    Up to 24-weeks

  • Cognition (attention, short, delayed, and working memory, verbal fluency, and abstraction).

    Cognition will be assessed with the Repeatable Battery for the Assessment of Neuropsychological Status Update (RBANS-U) List Learning, List Recall, List Recognition, Story Memory, Story Recall, Semantic Fluency and Picture Naming subtests and the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) Similarities and Digit Span subtests. All scores will be standard scores based on age norms.

    Up to 24-weeks

  • Post-acute COVID symptoms (PACS)

    Frequency and severity of 38 PACS symptoms will be assessed daily via an online survey. Each symptom will be rated on a scale of 0 (not present) to 5 (severe).

    Up to 24-weeks

  • Physical Function

    Physical function will be measured weekly via self-report with the Physical Function Short Form-36. Scores can range from 0 to 100 and higher scores indicate better function.

    Up to 24-weeks

Secondary Outcomes (6)

  • Depression

    Up to 24-weeks

  • Generalized anxiety

    Up to 24-weeks

  • State anxiety

    Up to 24-weeks

  • Trait anxiety

    Up to 24-weeks

  • Improvement in quality of life

    Up to 24-weeks

Study Arms (4)

Treadmill Exercise with Supplemental Oxygen

EXPERIMENTAL

Participants will receive 24 sessions (2 x week for 12 weeks) of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes.

Other: Treadmill ExerciseOther: Concentrated Oxygen

Treadmill Exercise with Air

SHAM COMPARATOR

Participants will receive 8 sessions (2 x week for 4 weeks) of treadmill exercise combined with air delivered via nasal cannula during exercise and 5-minutes of recovery. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes.

Other: Treadmill ExerciseOther: Concentrated OxygenOther: Concentrated Air

Supplemental Oxygen Only

SHAM COMPARATOR

Participants will receive 8 treatment sessions (2 x week for 4 weeks) of 6 liters per minute of continuous oxygen via nasal cannula for 30 minutes at rest. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three minutes. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes.

Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three minutes. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery.

  • Acute myocardial infarction within the past two days
  • Ongoing unstable angina
  • Uncontrolled cardiac arrhythmias
  • Active endocarditis
  • Symptomatic severe aortic stenosis
  • Decompensated heart failure
  • Active pulmonary embolism, pulmonary infarction, or deep venous thrombosis
  • Active myocarditis or pericarditis
  • Acute aortic dissection
  • Physical disability that precludes safe and adequate testing
  • Participants who demonstrate orthostatic intolerance or oxygen desaturation (\<90%) during the exercise tolerance test will no longer be eligible for the study because it is not safe for them to exercise on a treadmill.
