Sarcopenia is defined by the loss of muscle mass and function. In aging sarcopenia is due to
mild chronic inflammation but also to fiber-intrinsic defects, such as mitochondrial …

Ultrasound (US) imaging has been widely used in both research and clinical settings to
evaluate the morphological and mechanical properties of muscle and tendon. In elite sports …

Background Walking is an important factor in daily life. Among older adults, gait function
declines with age. In contrast to the many studies revealing gait differences between young …

For the observation of human joint cartilage, X-ray, computed tomography (CT) or magnetic
resonance imaging (MRI) are the main diagnostic tools to evaluate pathologies or traumas …

Robot-actuated mechanical loading (ML)–based therapies (“mechanotherapies”) can
promote regeneration after severe skeletal muscle injury, but the effectiveness of such …

During natural aging, skeletal muscle experiences impairments in mechanical performance
due, in part, to changes in muscle architecture and size, notably with a loss of muscle cross …

Skeletal muscle strength, mass, and function should be carefully monitored for signs of
decline with advanced adult age. An understanding of the pathophysiology and severity of …

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 …

The loss of muscle mass and force characterizes muscle atrophy in several different
conditions, which share the expression of atrogenes and the activation of their …

Aging leads to a decline in muscle mass and force-generating capacity. Ultrasound shear
wave elastography (SWE) is a non-invasive method to capture age-related muscular …
