The role of instrumental assessment of muscle mass in the diagnosis of sarcopenia

Sarcopenia increases the risk of adverse outcomes in older patients. Loss of muscle mass poses a threat to the functioning, independence and quality of life of an elderly person. It is necessary to determine the importance of clinical and instrumental assessment of the state of muscle tissue in patients with geriatric syndromes for understanding the tactics and diagnostic logistics of a patient with suspected sarcopenia. For this purpose, 156 patients over 60 years of age were examined, each of whom underwent a comprehensive geriatric assessment, wrist dynamometry, a 5-rise test from a chair, a walking speed test, SARC-F questionnaire testing, dual-energy X-ray absorptiometry with determination of muscle mass, and bioimpedance (BIA) was performed in 135 patients.) with the determination of the skeletal muscle mass index (SMMI). This article presents the results of an analysis of the association of the results of tests assessing muscle mass, strength and function with the functional status of patients.
