Whole-Body Electrostimulation for Functional Recovery in Post-COVID Syndrome

30 participantsStarted 2026-03

Plain-language 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.

Inclusion Criteria:Adults aged 18 years or older. Diagnosis of post-COVID syndrome (long COVID), with persistent symptoms following SARS-CoV-2 infection. Presence of fatigue and/or functional limitations associated with post-COVID syndrome. Ability to understand the study procedures and provide written informed consent. Ability to participate in the intervention and assessments according to the study protocol. \- Exclusion Criteria: Participation in other structured physical exercise or rehabilitation programs during the study period. Presence of severe cardiovascular disease or uncontrolled medical conditions that contraindicate physical activity or electrostimulation. Neurological disorders or severe neuromuscular diseases. Use of anabolic drugs or medications that may interfere with muscle function. Pregnancy. Epilepsy. Active skin lesions or dermatological conditions in areas where electrodes are applied. Recent oncological surgery. Acute venous thrombosis. Presence of cardiac pacemakers or implanted electronic or conductive medical devices. Any clinical deterioration or condition that, in the opinion of the investigators, would make participation unsafe. \-
