Human physiological signals are inherently rhythmic and have a hallmark feature in that
even distant intrasignal measurements are related to each other. This relationship is termed …

Background Walking and running are common forms of locomotion, both of which exhibit
variability over many gait cycles. Many studies have investigated the patterns generated …

This chapter covers basic principles of gait analysis. We discuss these principles in order to
provide the basis for understanding and analyzing the fundamental skill of gait. Our goal is …

Visually guided postural control emerges in response to task constraints. Task constraints
generate physiological fluctuations that foster the exploration of available sensory …

A long history of research has pointed to the importance of fractal fluctuations in physiology,
but so far, the physiological evidence of fractal fluctuations has been piecemeal and without …

Contemporary dynamical models of human postural control propose an intermittent
controller regulating the postural centre of pressure (CoP) about a stable saddle-shaped …

Mobile healthcare increasingly relies on analytical tools that can extract meaningful
information from ambulatory physiological recordings. We tested whether a nonlinear tool of …

Incorporating variability within gait retraining approaches has been proposed and shown to
lead to positive changes. Specifically, submitting the individuals to walk in synchrony to cues …

Chronic spinal pain (CSP) is a prevalent condition, and prolonged sitting at work can
contribute to it. Ergonomic factors like this can cause changes in motor variability. Variability …

If health can be defined as adaptability, then measures of adaptability are crucial.
Convergent findings across clinical areas established the notion that fractal properties in bio …
