Conventional biomechanical analyses of human movement have been generally derived
from linear mathematics. While these methods can be useful in many situations, they fail to …

We investigate postural sway data dynamics in older adult fallers and non-fallers. Center of
pressure (COP) signals were recorded during quiet standing in 28 older adults. The subjects …

The aim of this study was to assess the ability of multiscale sample entropy (MSE), refined
composite multiscale entropy (RCMSE), and complexity index (CI) to characterize gait …

The analysis of postural control has a long history. Traditionally, the amount of body sway is
solely used as an index of postural stability. Although this leads to some extent to an …

The authors' aim was to determine which variables allow for the characterization of motor
balance behavior. Traditional measures and nonlinear measures of center of pressure …

The present study was designed to assess the relative contribution of each leg to
unperturbed bipedal posture in lower limb amputees. To achieve this goal, eight unilateral …

Postural control is usually assessed by examining the fluctuations of the center of pressure
(COP). Balance maintenance is based on sensory feedback and neural interactions …

Exercises in virtual reality (VR) have recently become a popular form of rehabilitation and
are reported to be more effective than a standard rehabilitation protocol alone. The aim of …

Postural control is considered a key variable in team sports, such as handball, which require
abilities strongly related to balance. However, postural control and its relationship to the …

We compared postural control of expert gymnasts (G) to that of non-gymnasts (NG) during
bipedal closed-eyes quiet standing using conventional and nonlinear dynamical measures …
