Ultrasound Measurement of Quadriceps Shortening During Neuromuscular Electrical Stimulation in Critically Ill Patients

Diagnostic Accuracy of Early ulTrasound Measurement of Quadriceps Thickness During Neuromuscular EleCTrical Stimulation for the Diagnosis of ICU-acquired Weakness : an Observational Study (DETECT)

ICU-Aw is highly prevalent (50%) among critically ill patients. Its diagnosis is usually delayed as it requires patients' awakening and collaboration to provide accurate measurement.

This study aims to investigate the accuracy of an early ultrasound measurement of quadriceps shortening during neuromuscular electrical stimulation to diagnose future ICU-Aw in critically ill patients.
