Introduction: Age-related changes in muscle mass and muscle tissue composition contribute
to diminished strength in older adults. The objectives of this study are to examine if an …

Abstract Background/Objectives Sarcopenia is defined as the gradual age-associated loss
of both muscle quantity and strength in older adults, and is associated with increased …

Introduction A precise quantitative measurement of skeletal muscle mass is fundamental for
diagnosing sarcopenia in older individuals. The current techniques of assessment, including …

Background Muscle thickness and echo intensity measured using ultrasound imaging
represent both increased muscle volume and connective tissue accumulation. In …

Estimates of muscle tissue composition may have greater prognostic value than lean body
mass levels regarding health-related outcomes. Ultrasound provides a relatively low cost …

Objective To establish muscle-specific cut-off values for ultrasound-based detection of low
muscle mass, and to assess its prevalence in a population of frail older subjects when …

This review evaluates the reliability and validity of ultrasound to quantify muscles in older
adults. The databases PubMed, Cochrane, and Cumulative Index to Nursing and Allied …

Background Sarcopenia is diagnosed on the basis of skeletal muscle mass and muscle
strength/function. However, more simple and accurate measures for muscle mass and …

Background The assessment of muscle mass is a key determinant of the diagnosis of
sarcopenia. We introduce for the first time an ultrasound imaging method for diagnosing …

Purpose Ultrasound-based prediction methods for the detection of low muscle mass for
sarcopenia in older adults have been explored previously; however, the muscle that most …
