Abstract
Objective: development of an applied clinical calculator for calculating the appendicular mass of skeletal muscles (ASMM Calculator) in elderly patients based on bioimpedance analysis of body composition and anthropometry.Material and methods: the algorithm of the ASMM Calculator was developed based on the analysis of the results of a single-stage crosssectional study of G. Sergi (Department of Geriatrics, University of Padua, Italy); the calculation of appendicular musculoskeletal mass and its index is based on the values of anthropometry and bioimpedance analysis of body composition.Results:the matrix of the ASMM Calculator allows you to determine objective quantitative criteria for sarcopenia (appendicular musculoskeletal mass and its index) based on the values of five independent variables: the patient’s gender; height and body weight, electrical and reactive esistance of the body, the program provides for use directly in outpatient admission, has a volume of 12 kB, does not require specific hardware and software means, can be installed on a mobile device.Conclusions: the use of the ASMM calculator in clinical practice allows the doctor to establish diagnostic criteria for sarcopenia in a timely manner, does not require significant professional time, provides grounds for verifying the diagnosis in accordance with the principles of evidence-based medicine; the program can be integrated into various medical information systems as a module of the medical decision support system.
