Concordance between changes in calf circumference and muscle mass exists: A narrative literature review.

Technological methods such as BIA or DXA are not always accessible in clinical practice, thus GLIM supports the use of calf circumference measurements to examine muscle mass. However, it has not been described if measurements of calf circumference can detect a change in muscle mass to the same degree as the technological methods. The aim of this study was to assess, whether changes in calf circumference can be used as a valid proxy for changes in muscle mass.
