Nutritional testing tools and indicators
lower limb muscle mass, skeletal muscle mass, upper arm muscle circumference
In this study, a body composition analyser (INBODY S10, Biospace Co., Ltd., Korea) was used to measure the body composition of the patients, which was subsequently used for the determination of nutritional status via the BIA method. Prior to the measurement, the patient was asked to adopt a sitting or lying position, with their upper limbs abducted by 15° and the lower limbs naturally separated, while the electrode clips were fixed on the thumb, middle finger and heel of both sides. Before placing the electrodes, the skin was cleaned with 75% ethanol to reduce any skin contact resistance. The patients were strictly forbidden to eat, drink, speak or move during the test. Before commencing the measurement, the patient's hospital number, gender, age, height, weight and other information were recorded.Body composition analysis can be used to measure protein mass (kg), skeletal muscle mass (kg), upper arm muscle circumference (cm), left lower limb muscle mass (kg), right lower limb muscle mass (kg), body fat (kg), body fat percentage (%), visceral fat area (cm
