Background: Heart rate variability (HRV) is an important indicator of autonomic modulation
of cardiovascular function. Diabetes can alter cardiac autonomic modulation by damaging …

Objective To provide normative postural stability data in young subjects. Methods Ninety-six
healthy participants (58 W, 28±6y) stood on a force plate during 60 s. We measured effects …

Fractal time series analysis methods are commonly used for analyzing center of pressure
(COP) signals with the goal of revealing the underlying neuromuscular processes for upright …

Background. The usefulness of posturography in the clinical screening of older adults for fall
risk has been limited by a lack of standardization in testing methodology and data reporting …

Detrended Fluctuation Analysis (DFA) has become a standard method to quantify the
correlations and scaling properties of real-world complex time series. For a given scale ℓ of …

Music presents a complex case of movement timing, as one to several dozen musicians
coordinate their actions at short time-scales. This process is often directed by a conductor …

Introduction: Detrended Fluctuation Analysis (DFA) has been used to investigate self-
similarity in center of pressure (CoP) time series. For fractional gaussian noise (fGn) signals …

Considerable disagreement exists on the linearity of the development of standing balance in
children. This study aimed to use different traditional and nonlinear methods to investigate …

Purpose Postural control during quiet standing has been modeled by concepts using
kinematic variables estimated from center of pressure (COP) signals. The concept of position …

This study analyzed the postural control of older adults on inclined surfaces, and was
conducted in 17 elderly adults and 18 young adults of both genders. Ground reaction forces …
