Start with 3 Initial Screening Questions

Falling is one of the risks that should be considered as a serious risk caused by sarcopenia in daily living of senior patients. The CDC National Center for Injury Prevention and Control: STEADI recommends to make questions about falling when you see patients 65 or older. It can be an initial interview to screen risks of sarcopenia.

MRI, DEXA or BIA Is Used for a Rigorous Diagnosis

Tools and criteria for the rigorous diagnosis of sarcopenia have been still debated. In 2014, the FNIH Sarcopenia Project suggested the cutpoints based on results of their multi-center study and discussion of the FNIH-NIA-FDA Sarcopenia Consensus Summit 2012. In such cutpoints, muscle mass is focused as well as muscle functional parameters.


However, it is not so easy to measure muscle mass in the real clinical practice, because the equipment to measure muscle mass, such as MRI, dual energy X-ray absorptiometry (DEXA) or bioimpedence analysis (BIA: a body composition scale), is not available in many clinics. In fact, in the 2012 summit, it was confirmed that it is much more important to pay attention to muscle function which leads to decreased QOL or mortality rather than strictness to muscle mass in the real clinical practice.
