Vagal Nerve Stimulation for Post COVID Fatigue

Mayo Clinic18 enrolled

Overview

The purpose of this study is to evaluate the impact of vagal nerve stimulation on patients with post COVID syndrome who have fatigue and headache.

Patients, after consenting, will perform questionnaires, have a blood samples taken, and undergo PET/CT scans of the brain. Patients will then be randomized to either receive vagal nerve stimulation, or continue standard clinical care. For those randomized to receive treatment, they will be given a device and asked to follow a specific regimen daily for 12 weeks.

Outcomes

Primary Outcomes

Change in Post-COVID Functional Status Score

Measurement is the change in scoring determined through patients' self-reported Post-COVID Functional Status Score survey, which assesses COVID-19 symptom impact on a grading scale of 0 = no limitations to 4 = severe limitations. Thus, higher scores are a worse outcome, and a change indicating an increase is a worsening of functional status.

Time frame: Baseline to 12 weeks

Secondary Outcomes

Change in PROMIS Fatigue Scale T Score

Measurement is the change in score determined through patients' self-reported PROMIS Short Form v1.0 - Fatigue 7a. The PROMIS Fatigue Scale assesses 7 items on a scale of 1 (never) to 5 (always). Scale scores were converted to T scores using the published guidelines. A T-score of 50 is the average for the general population with a standard deviation of 10 because calibration testing was performed on a large sample of the general population. A higher PROMIS Fatigue T-score represents more of the concept being measured; thus, an increase in fatigue T score corresponds to more fatigue - which is a worse outcome.

Time frame: Baseline to 12 weeks
