Shear-wave elastography for muscle assessment in geriatric outpatients at increased risk of falling.

ABSTRACT:

Purpose

Sarcopenia, defined by the loss of muscle strength, quantity, and quality, increases the risk of functional decline and adverse outcomes. Shear-wave elastography (SWE), a non-invasive ultrasound-based technique, quantifies muscle stiffness. However, its diagnostic value in sarcopenia remains unclear. This study investigated the relationship between rectus femoris (RF) stiffness and physical performance in geriatric outpatients with and without sarcopenia.

Methods

This cross-sectional study, conducted in a geriatric outpatient clinic, included consecutive patients aged ≥ 65 years. Muscle stiffness was assessed using SWE, and muscle thickness was measured to estimate appendicular lean mass (ALM). Sarcopenia was diagnosed per EWGSOP2 criteria. Analyses included group co
