What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether adding neuromuscular electrical stimulation (NMES) to standard physical therapy helps ICU patients on breathing machines recover muscle strength. About 150 adults will be randomly assigned to get either physical therapy alone or physical therapy plus NMES on their legs. The main goal is to see if NMES improves muscle strength by the time they leave the ICU.

What this could mean

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

Active substance
Neuromuscular electrical stimulation (NMES) device
What this could lead to
If it works, this could offer a simple way to help critically ill patients regain muscle strength faster and reduce long-term weakness.
What could go wrong
This is a small, early-stage trial (150 participants) testing a device, so results may not apply broadly. The added benefit over standard therapy may be small or absent.

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.

Participants

About 150 people

The number the study aims to enrol. It can still change while the study runs.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

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: * Patients will be eligible if they are 18 years or older, are under invasive mechanical ventilation (IMV), and are expected to require IMV for more than 48 hours. Exclusion Criteria: * Body mass index (BMI) greater than or equal to 35 kg/m²; * Length of ICU stay longer than 7 ICU-free days or more than 3 continuous days of invasive mechanical ventilation (IMV) before enrollment; * Known intracranial process (e.g., stroke, intracranial hypertension); * Neuromuscular disease (e.g., Guillain-Barré syndrome, myasthenia gravis) at ICU admission; * Inability to speak Portuguese or pre-existing cognitive impairment prior to ICU admission; * Any condition that prevents neuromuscular electrical stimulation (NMES) treatment or assessment of the primary outcome in both legs (e.g., skin lesions, fractures, or amputation); * inability to transfer from bed to chair with or without assistance prior to hospital admission; * Cardiac arrest as the cause of ICU admission or cardiac arrest before screening; * Deep vein thrombosis (DVT) or pulmonary embolism (PE) treated for less than 48 hours; * Pregnant patients; * Known or suspected malignancy in the legs; * Any care limitation including a do-not-resuscitate order.
