Background Age-related gait changes may play a critical role in functional limitations of
older adults. Despite sizable interest in determining how age alters walking mechanics …

Older adults walk slower and with a higher metabolic energy expenditure than younger
adults. In this review, we explore the hypothesis that age-related declines in Achilles tendon …

With aging comes reductions in the quality and size of skeletal muscle. These changes
influence the force-generating capacity of skeletal muscle and contribute to movement …

Purpose Preferred walking speed (PWS) represents a performance measure of mobility in
older individuals. PWS is usually assessed during overground (via a 2–40 m walkway) or …

During locomotion, the human ankle-foot system dynamically alters its gearing, or leverage
of the ankle joint on the ground. Shifting ankle-foot gearing regulates speed of plantarflexor …

Background The plantar intrinsic foot muscles (PIFMs) have a role in dynamic functions,
such as balance and propulsion, which are vital to walking. These muscles atrophy in older …

Substantial evidence demonstrates that falls in older adults are leading causes of fatal and
non-fatal injuries and lead to negative impacts on the quality of life in the aging population …

Introduction Compared to young adults, older adults walk with smaller propulsive forces and
a redistribution to more proximal leg muscles for power generation during push-off. Despite …

Background Compared to young adults, older adults walk slower, with shorter strides, and
with a characteristic decrease in ankle power output. Seemingly in response, older adults …

Introduction Early screening and identification are crucial for fall prevention, and develo**
a new method to predict fall risk in the elderly can address the current lack of objectivity in …
