"The most widely accepted definition, from the European Working Group on sarcopenia in older people (EWGSOP), suggests relying on both decreased muscle function and diminished muscle mass when diagnosing sarcopenia. For clinical management the following staging system has been proposed:"
"Appendicular skeletal muscle mass (ASM) represents the sum of the lean muscle mass of the arms and legs and is commonly used as a diagnostic index for assessing sarcopenia 3. Appendicular skeletal muscle mass may be adjusted for height, body weight, or BMI too."
"Note that several other definitions for the normal range of TAMA exist, some also incorporating subcategories based on BMI, and the cutoff values are not yet standardised 3. The TAMA, when divided by the patient's height, gives the skeletal muscle index sarcopenia measure."
"Total abdominal muscle area (TAMA) is a measure of the area composed by muscles measured in the axial plane at the level of the L3 vertebra. (NB: This measure can be performed by automated tools which compensate for issues of fatty infiltration of muscle. Recommended lower limits of TAMA for adults:"
Expected headings
"DEXA"
"Dual-energy x-ray absorptiometry (DEXA) is the gold standard imaging modality in the evaluation of sarcopenia and has been used for the greatest number of trials 1. Ultrasound, CT and MRI have also been used in the assessment of appendicular skeletal muscle mass 1."
