Background Physical and functional losses due to aging and diseases decrease human
mobility, independence, and quality of life. This study is aimed at summarizing and …

Introduction Given the high rate of falls during walking in people with idiopathic Parkinson's
disease (PD), identifying at risk individuals and developing targeted interventions to reduce …

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 …

Gait parameters that can be measured with simple instrumentation may hold promise for
identifying individuals at risk of falling. Increased variability of gait is associated with …

Traditional biomechanical analyses of human movement are generally derived from linear
mathematics. While these methods can be useful in many situations, they do not describe …

The purpose of the current study was to investigate whether adaptations of stride length,
stride frequency, and walking speed, independently influence local dynamic stability and the …

Self-selected walking speed is an important aspect of mobility. Exoskeletons can increase
walking speed, but the mechanisms behind these changes and the upper limits on …

Arm swing during human gait has been shown to reduce both angular momentum about the
vertical and energy expenditure, and has been hypothesized to enhance gait stability. To …

It has frequently been proposed that lowering walking speed is a strategy to enhance gait
stability and to decrease the probability of falling. However, previous studies have not been …

Gait disorders are major causes of falls in patients with neurological diseases.
Understanding these disorders allows prevention and better insights into underlying …
