Combining muscle activation and high-protein nutrition to improve muscle health in ICU patients

Improved Muscle Metabolism by Combination of Muscle Activation and Protein Substitution: a Randomized, Outcome-assessor Blinded, Proof-of-concept Study (IMEMPRO)

Not applicable Interventional Technical University of Munich · NCT05919940

This study is testing if giving high-protein nutrition along with muscle activation exercises can help critically ill patients in the ICU keep their muscles strong and recover better.

What this trial studies

This study investigates the effects of early enteral high-protein nutrition combined with early muscle activation on muscle atrophy in critically ill patients suffering from ICU Acquired Weakness (ICUAW). It will enroll 40 patients who require enteral nutrition and will be divided into two groups: one receiving enhanced protein intake and neuromuscular electrical stimulation (NMES) alongside mobilization, and the other receiving standard care. The aim is to assess whether this combined approach can mitigate muscle atrophy and improve patient outcomes during and after their ICU stay.

Who should consider this trial

Good fit: Ideal candidates are critically ill adults aged 18 and older, newly admitted to the ICU within the last 48 hours, and requiring enteral nutrition.

Not a fit: Patients with a BMI over 30, prior neuromuscular diseases, or those expected to die or withdraw life-sustaining treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce muscle atrophy and improve recovery outcomes for critically ill patients.

How similar studies have performed: While the combination of early mobilization and high-protein nutrition has been explored separately, this specific approach is novel and has not been adequately tested in previous studies.
