Purpose This narrative review provides an overview of the current knowledge of B-mode
ultrasound-derived echo intensity (EI) as an indicator of skeletal muscle quality. Method …

Purpose Measurement of muscle mass is paramount in the screening and diagnosis of
sarcopenia. Besides muscle quantity however, also quality assessment is important …

Background Dynapenia is prevalent in people with reduced skeletal muscle mass, ie
sarcopenia, but a certain population develops muscle strength loss despite having normal …

Muscle quality defined as the ratio of muscle strength to muscle mass disregards underlying
factors which influence muscle strength. The aim of this review was to investigate the …

Muscle echo intensity, as measured by ultrasonography, could be used as a new marker of
functional performance in older populations. This scoping review aimed to present evidence …

Low‐radiodensity skeletal muscle has been related to the degree of muscle fat infiltration
and seems to be associated with worse outcomes. The aim of this study was to summarize …

Recently, an equation that allows investigators to correct echo intensity for subcutaneous fat
was developed. We evaluated correlations between uncorrected and corrected echo …

Muscle function and exercise performance measures, such as muscle endurance capacity,
maximal strength, chair stand score, gait speed, and Timed Up and Go score, are evaluated …

Echo intensity (EI) is being increasingly utilized by investigators as an index of skeletal
muscle quality. Previous studies have reported independent associations between EI versus …

Background In aging, muscle stiffness is considered as one of the factors associated with the
reduction of force generation capability. There have been inconsistent findings on age …
