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 Gait disorders are common in the elderly populations, and their prevalence
increases with age. Abnormal gait has been associated with greater risk for adverse …

Muscles are the actuators that drive human movement. However, despite many decades of
work, we still cannot readily assess the forces that muscles transmit during human …

Background Habitual walking speed predicts many clinical conditions later in life, but it
declines with age. However, which particular exercise intervention can minimize the age …

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 …

Previous studies have identified differences in gait kinetics between healthy older and
young adults. However, the underlying factors that cause these changes are not well …

Characterizing the quasi-stiffness and work of lower extremity joints is critical for evaluating
human locomotion and designing assistive devices such as prostheses and orthoses …

The free Achilles tendon (AT) consists of distinct fascicles arising from each of the triceps
surae muscles that may give rise to non-uniform behavior during functional tasks such as …

Objective: the present study investigated the effects of walking under different challenges
and kinematics and kinetics generated during these activities and how these vary with age …

The aims of this paper were to investigate the effectiveness of a newly developed wearable
hip assist robot, that uses an active assist algorithm to improve gait function, muscle effort …
