Psychophysiologic Symptom Relief Therapy for Post-Acute Sequelae of Coronavirus Disease 2019

Abstract

Objective: To determine if psychophysiologic symptom relief therapy (PSRT) will reduce symptom burden in patients suffering from post-acute sequelae of coronavirus disease 2019 (COVID-19) (PASC) who had mild/moderate acute COVID-19 disease without objective evidence of organ injury. Patients and Methods: Twenty-three adults under the age of 60 years with PASC for at least 12 weeks after COVID-19 infection were enrolled in an interventional cohort study conducted via a virtual platform between May 18, 2021 and August 7, 2022. Participants received PSRT during a 13-week (approximately 44-hour) course. Participants were administered validated questionnaires at baseline and at 4, 8, and 13 weeks. The primary outcome was a change in somatic symptoms from baseline, measured using the Somatic Symptom Scale-8, at 13 weeks. Results: The median duration of symptoms before joining the study was 267 days (interquartile range: 144, 460). The mean Somatic Symptom Scale-8 score of the cohort decreased from baseline by 8.5 (95% CI: 5.7-11.4), 9.4 (95% CI: 6.9-11.9), and 10.9 (95% CI: 8.3-13.5) at 4, 8, and 13 weeks, respectively (all P<.001). Participants also experienced statistically significant improvements across other secondary outcomes including changes in dyspnea, fatigue, and pain (all P<.001). Conclusion: PSRT may effectively decrease symptom burden in patients suffering from PASC without evidence of organ injury. The study was registered on clinicaltrials.gov (NCT 04854772).
