Muscle Assessment in Stroke Study (MASS): Detection of Muscle Loss in Acute Stroke Patients Who Need Enteral Nutrition

This study is a multicenter, prospective observational study. The study period is 12 months. There are no investigational products to be followed or used in the study.

Demographic data, stroke subtype, lesion localization, anthropometric measures will be recorded. Muscle in three different anatomical sites will be measured by CT following admission in patients included in the study.

For anthropometric measurements, height, body weight, body mass index, waist circumference, triceps skin thickness and calf circumference values will be used.

The muscle mass will be measured from the paraspinal muscles at the L3 vertebra level and from the muscles around the humerus and femur on the non-paralytic side of the extremities by CT.

All patients will receive standard enteral nutritional support with a standardized calorie and protein-based protocol recommended by international guidelines. The choice of the commercial enteral product will be left to the investigator, without any encouragement or restriction for use of any commercial product.
