Recurrence is a fundamental property of dynamical systems, which can be exploited to
characterise the system's behaviour in phase space. A powerful tool for their visualisation …

In recent years, concepts and tools from dynamical systems theory have been successfully
applied to the study of movement systems, contradicting traditional views of variability as …

Ecological Psychology is an embodied, situated, and non-representational approach
pioneered by JJ Gibson and EJ Gibson. This theory aims to offer a third way beyond …

The research was designed to evaluate interpersonal coordination during conversation with
a new measurement tool. The experiment uses an analysis based on recurrence strategies …

Fall injuries are responsible for physical dysfunction, significant disability, and loss of
independence among elderly. Poor postural control is one of the major risk factors for falling …

The influence of attention on the dynamical structure of postural sway was examined in 30
healthy young adults by manipulating the focus of attention. In line with the proposed direct …

In investigations into perception-action systems, variability of observable behavior may be
considered to (a) interfere with inquiry,(b) be neither detrimental nor particularly useful to …

The purpose of the present project was to determine whether postural sway varied with the
difficulty of a concurrent unrelated cognitive task. Participants stood on a compliant surface …

We analyze the irregularity of human postural sway data during quiet standing using the
sample entropy (SampEn) algorithm. By considering recent methodological developments …

In a recent study, De Haart et al.(Arch Phys Med Rehabil 85: 886–895, 2004) investigated
the recovery of balance in stroke patients using traditional analyses of center-of-pressure …
