Could a simple electrical zap help ventilator patients walk again sooner?

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.

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.
