Muscle–tendon units about the ankle joint generate a burst of positive power during the step-
to-step transition in human walking, termed ankle push-off, but there is no scientific …

The prevalence of mobility impairment among old adults (older than 65 yr) is profound; 17%,
28%, and 47% of people aged 65–74, 75–84, and older than 85 years, respectively, report …

This article presents an assist-as-needed (AAN) control framework for exoskeleton
assistance based on human volitional effort prediction via a Hill-type neuromuscular model …

Lower-limb exoskeletons used to improve free-living mobility for individuals with
neuromuscular impairment must be controlled to prescribe assistance that adapts to the …

Ankle exoskeletons hold potential to augment human walking ability, yet their use in free-
living environments has been limited by the absence of practical and effective control …

Background Bilateral plantarflexor muscle weakness is a common impairment in many
neuromuscular diseases. However, the way in which severity of plantarflexor weakness …

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 …

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 …

Robotic lower limb prostheses aim to replicate the power-generating capability of biological
joints during locomotion to empower individuals with lower limb loss. However, recent …

Tendons transfer forces produced by muscle to the skeletal system and can therefore have a
large influence on movement effectiveness and safety. Tendons are mechanosensitive …
