What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether adding functional electrical stimulation (FES) to cycling exercises helps people who survived severe COVID-19 recover more quickly. Twenty-two patients who had been on ventilators in the ICU took part in a 4-week rehab program. Half did cycling with FES, the other half without. The goal was to see if FES could reduce time spent sitting or lying down, helping them regain strength and activity.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
functional electrical stimulation (FES) during cycling
What this could lead to
If it works, this could point toward a more effective rehab method for severe COVID-19 survivors, helping them recover mobility faster.
What could go wrong
This is a very small, early-stage trial with only 22 participants, so results may not apply broadly. The benefit over standard cycling alone is uncertain.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years * Being hospitalized for rehabilitation because of a severe form of the COVID-19 that required an admission in intensive care unit for acute distress respiratory syndrome treated by mechanical ventilation. * Being beneficiary of the French social security. Exclusion Criteria: * Person requiring supplementation in oxygen \> 4 L/min because above this threshold, the oxygen flow is considered to be associated with an increased risk of aerosolization and further virus spread in patient being contagious; * Oxygen desaturation during exercise (i.e., SpO2 \< 90%) and requiring supplementation in oxygen \> 4 L/min. * Person showing a lower motor neuron disease as defined by the medical research council score \< 48/60 including hyporeflexia (quadricipital and triceps tendons) and decrease in lower limb sensation. * Persons showing denervated muscle (including quadriceps, hamstring, gluteus and triceps) confirmed by electromyography because the electrical stimulations delivered by the stimulator (i.e., symmetric and rectangular biphasic currents) are not appropriate to restore a pedaling movement; * Person with osteo-articular disease at lower limbs including reduction in range of motion at the hip, knee and ankle preventing cycling pedaling in a sitting position; * Persons with associated neurologic or psychiatric disease; * Person with a medical contraindication to intensive rehabilitation; * Person suffering from suspected or diagnosed epilepsy; * Person with an implanted device; * Person included in another ongoing research or during an exclusion period of another research; * Adults protected by law (guardianship or curatorship); * Pregnant women
