Muscle mass in critically ill patients: analysis using ultrasound, traditional bioelectrical impedance analysis, and wearable devices: a prospective observational study

Ultrasound is a reliable method for monitoring muscle atrophy in critically ill patients, demonstrating a consistent decrease in muscle mass. The outcomes of traditional BIA and wearable devices suggest that careful consideration of their interpretations is necessary. Utilizing these tools may be valuable for assessing patient prognosis and facilitating more proactive interventions for patients experiencing muscle loss.
