Pursuing Reduction in Fatigue After COVID-19 Via Exercise and Rehabilitation (PREFACER): A Randomized Feasibility Trial

The COVIDEx intervention was developed by triangulating patient preferences/needs, clinicians' expertise, and best current evidence specific to Long COVID and adapted from interventions for other complex fatigue disorders, which are consistent with evidence informed practice. The program is delivered by trained instructors and comprises of two 50-minute sessions each week for eight weeks. The intervention is designed to be delivered virtually in groups of 6 patients, to eliminate travel requirements for the study. The components of the program are: (i) warm-up (1 min), (ii) cardio training (5 min), (iii) rest (3 min), (iv) balance training (5 min), (v) breathing exercises (3 min), (vi) cognitive training (5 min), (vii) strengthening training (5 min), and (viii) stretching (10min). The COVIDEx program will be paced in order to prevent post-exertional malaise (PEM) in participants.
