Could a zappy vest and protein drink save ICU Patients' muscles?
NCT ID NCT07430969
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tests whether a single session of whole-body electrical muscle stimulation, with or without a dose of amino acids, can improve protein balance in sedated ICU patients on ventilators. Thirty adults will be split into three groups: sham stimulation, real stimulation, or real stimulation plus an amino acid drink. Researchers will measure muscle protein turnover and blood flow to see if these interventions help prevent muscle wasting.
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 and amino acid bolus
- What this could lead to
- If it works, this could point toward a simple, drug-free way to reduce muscle wasting in critically ill patients on ventilators.
- What could go wrong
- This is a very early, small study (30 people) looking at short-term protein balance, not long-term muscle strength or recovery. The results may not translate to real-world benefits.
