Whole-Body Electrostimulation for Functional Recovery in Post-COVID Syndrome
Sponsor: Universidad Rey Juan Carlos
Summary
Post-COVID syndrome is a condition that affects some people after recovering from the acute phase of COVID-19. Common symptoms include persistent fatigue, reduced physical capacity, and difficulties performing everyday activities, which can significantly impact quality of life and independence. At present, there is limited scientific evidence on effective rehabilitation strategies for this population. The purpose of this study is to evaluate whether the use of a whole-body electrostimulation suit can improve fatigue, physical performance, and functional independence in people with post-COVID syndrome. Whole-body electrostimulation is a non-pharmacological technique that uses low-frequency electrical impulses to activate multiple muscle groups simultaneously and has shown potential benefits in other clinical populations. This is a randomized, double-blind, controlled pilot clinical trial. Participants will be randomly assigned to either an experimental group, which will receive active whole-body electrostimulation during functional activities, or a control group, which will follow the same sessions using the electrostimulation suit with minimal stimulation (placebo condition). Neither participants nor outcome assessors will know which group each participant belongs to. The intervention will consist of 12 supervised sessions conducted once per week. Outcomes will be assessed before and after the intervention, with an additional follow-up assessment three months later. The main outcomes include fatigue levels, functional capacity, physical performance, and independence in activities of daily living. Safety and tolerance to the intervention will be monitored throughout the study. The results of this study may help to determine the feasibility and potential effectiveness of whole-body electrostimulation as a rehabilitation tool for people with post-COVID syndrome and provide preliminary data for future larger-scale clinical trials.

Interventions
Whole-Body Electromyostimulation Suit
The intervention consists of the use of a whole-body electromyostimulation (WB-EMS) suit with integrated surface electrodes designed to stimulate multiple large muscle groups simultaneously. Electrical stimulation is delivered at low-to-moderate frequencies and individualized intensities during supervised functional activities. Stimulation parameters are adjusted according to participant tolerance to achieve visible and tolerable muscle contractions. Sessions are conducted once per week for a total of 12 sessions, with progressive increases in session duration from 10 to 20 minutes. In the control condition, the same device is used with minimal, non-therapeutic electrical stimulation.
