Abstract:
Background: Post Exertional Symptom Exacerbation (PESE) is a characteristic symptom of Post-COVID Syndrome (PCS).
Objectives: This prospective study investigated the effect of a 6-week structured World Health Organisation (WHO) Borg CR-10 5-phase pacing protocol on PESE episodes and quality of life in a cohort of individuals with long-standing PCS (average duration of symptoms was 17 months).
Methods: Participants received weekly telephone calls with a clinician to complete the Leeds PESE Questionnaire (LPQ) and identify the appropriate phase of the pacing protocol. EQ-5D 5L was completed at the intervention’s beginning and end to measure overall health.
Results: Thirty-one participants completed the 6-week protocol, with a statistically and clinically significant reduction in the average number of PESE episodes (from 3.4 episodes in week one to 1.1 in week six), with an average decrease of 16% (95% CI: 9% to 24%; p<0.001) each week, and reduction across all three exertional triggers (physical, cognitive, and emotional). Physical activity levels showed moderate improvements during the intervention period. Mean EQ-5D 5L scores improved from 51.4 points to 60.6 points (paired difference of 9.2 points, 95% CI: 3.2 to 15.2 points; p=0.004).
Conclusions: A structured pacing protocol significantly reduces PESE episodes and improves overall health in PCS.
