Accelerometers objectively monitor physical activity and sedentary patterns and are
increasingly used in the research setting. It is important to maintain consistency in data …

Parkinson's disease (PD) is a common, debilitating neurodegenerative disease. Gait
disturbances are a frequent cause of disability and impairment for patients with PD. This …

Variability in human walking depends on individual physiology, environment, and walking
task. Consequently, in the field of wearable robotics, there is a clear need for customizing …

The study of gait variability, the stride-to-stride fluctuations in walking, offers a
complementary way of quantifying locomotion and its changes with aging and disease as …

The metabolic energy cost of walking is determined, to a large degree, by body mass, but it
is not clear how body composition and mass distribution influence this cost. We tested the …

Falls not only present a considerable health threat, but the resulting treatment and loss of
working days also place a heavy economic burden on society. Gait instability is a major fall …

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 …

Recent reports suggest that external cueing improves stride length and gait speed in
Parkinson's disease (PD). The purpose of the present study was to examine the influence of …

Aim: To investigate mechanical work, efficiency, and antagonist muscle co‐activation with a
view to better understand the cause of the elevated metabolic cost of walking (CW) in older …

Background The ability to maintain a steady gait rhythm is impaired in patients with
Parkinson's disease (PD). This aspect of locomotor dyscontrol, which likely reflects impaired …
