Background Understanding the effects of gait speed on biomechanical variables is
fundamental for a proper evaluation of alterations in gait, since pathological individuals tend …

Background and Objectives: Ankle injuries are the most common type of injury in healthy
active individuals. If not treated properly, recurrent sprains can lead to a condition of chronic …

Abstract Changes in old age that contribute to the complex issue of an increased metabolic
cost of walking (mass-specific energy cost per unit distance traveled) in older adults appear …

Human walking is usually conceived as the cyclic rotation of the limbs. The goal of lower-
limb movements, however, is the forward translation of the body system, which can be …

Consumer wearable and smartphone devices provide an accessible means to objectively
measure physical activity (PA) through step counts. With the increasing proliferation of this …

Aging of human skeletal muscles is associated with increased passive stiffness, but it is still
debated whether muscle fibers or extracellular matrix (ECM) are the determinants of such …

As we age, there is a wide range of changes in motor, sensory, cognitive, and temporal
processing due to alterations in the functioning of the central nervous and musculoskeletal …

The intramuscular connective tissue plays a critical role in maintaining the structural integrity
of the muscle and in providing mechanical support. The current study investigates age …

Background A comprehensive understanding of healthy gait patterns is a critical first step
towards understanding age-related pathologies and disorders that are commonly …

Abstract Changes in human gait resulting from ageing or neurodegenerative diseases are
multifactorial. Here we assess the effects of age and Parkinson's disease (PD) on …
