Objective: To evaluate the effect of a low-moderate telerehabilitation exercise protocol on physical and respiratory capacities in severe post-COVID-19 patients two months after hospital discharge.
Design: A parallel-group, observer-blinded randomized controlled trial.
Setting: Participants were recruited from a hospital setting and underwent remote rehabilitation. Participants: participants (both sexes) with severe COVID-19, discharged from the hospital two months prior, were randomly assigned to either an intervention or a control group.
Interventions: The intervention group received 12 weeks of telerehabilitation, with physiotherapist-supervised sessions twice a week for 50 minutes. The control group did not receive any rehabilitation intervention.
Main Outcome Measures: The primary outcomes were physical and respiratory capacities, assessed by spirometry, handgrip strength, stair climbing test, sit-to-stand test, core stability test, short physical performance battery, postural balance, and flexibility.
Results: Significant improvements were observed in handgrip strength in the dominant limb (p < 0.001) and non-dominant limb (p = 0.003), and in postural balance (p < 0.001). However, no significant changes were found in other physical or respiratory parameters.
Conclusions: Low-intensity telerehabilitation did not significantly improve overall physical or respiratory capacities in severe post-COVID-19 patients when initiated two months after hospital discharge. These findings highlight the need for more intensive and personalized rehabilitation approaches for this population.
