Variability is a natural and important feature of human movement. Using existing theoretical frameworks as a foundation, we propose a new model to explain movement variability as it relates to motor learning and health. We contend that mature motor skills and healthy states are associated with an optimal amount of movement variability. This variability also has form and is characterized by a chaotic structure. Less than optimal movement variability characterizes biological systems that are…

Multifractality, Interactivity, and the Adaptive Capacity of the Human Movement System: A Perspective for Advancing the Conceptual Basis of Neurologic Physical Therapy.
TLDR
The implications of recent evidence that optimal movement variability, which previously had been associated with adaptable motor behavior, contains a specific complex nonlinear feature known as "multifractality" are discussed.
Human movement variability, nonlinear dynamics, and pathology: is there a connection?
A holistic approach to study the temporal variability in gait.
A Perspective on Human Movement Variability With Applications in Infancy Motor Development
TLDR
The theoretical model of optimal movement variability, which suggests that the development of healthy and highly adaptable systems relies on the achievement of an optimal state of variability, is described as it relates to motor development in infancy and specifically theDevelopment of sitting posture.
Movement Variability and the Use of Nonlinear Tools: Principles to Guide Physical Therapist Practice
TLDR
This perspective article argues for changes in the way therapists view variability, both in theory and in action, to create a springboard for new directions in physical therapist research and practice.
Distinguishing Two Types of Variability in a Sit-to-Stand Task.
TLDR
The results suggest that a combination of linear and nonlinear analyses is useful in identifying the proportion of observed variability that may be attributed to structured, controlled sources.
Motor variability in occupational health and performance.
NON-LINEAR TOOLS AND METHODOLOGICAL CONCERNS MEASURING HUMAN MOVEMENT VARIABILITY: AN OVERVIEW
In recent years, several works have explored variability using different approaches, trying to describe the variations in motor movement. Traditionally, movement variability was regarded as a system…

TLDR
Nonlinear mathematical techniques that quantify physiologic dynamics may predict the onset of frailty, and interventions aimed toward restoring healthy dynamics may prevent functional decline.

TLDR
The variability associated with exploring available movement possibilities teaches patients which perceptual-motor aspects need to be monitored, and rules of coordination can be spontaneously generalized to a variety of similar situations.
Peabody Developmental Motor Scales
TLDR
This quotient measures the ability to utilize the large muscle systems to move from place to place, assume a stable posture when not moving, react automatically to environmental changes, and catch/throw objects.

Fractal dynamics in physiology: Alterations with disease and aging
TLDR
Application of fractal analysis may provide new approaches to assessing cardiac risk and forecasting sudden cardiac death, as well as to monitoring the aging process, and similar approaches show promise in assessing other regulatory systems, such as human gait control in health and disease.

Recovery of postural control after cerebral concussion: new insights using approximate entropy.
TLDR
The effects of cerebral concussion on postural control appear to persist for longer than 3 to 4 days, even among athletes with no signs of unsteady injured athletes, and this results may reflect changes in neurophysiologic or mechanical constraints in the return-to-play decision.
Nonlinear analysis of the development of sitting postural control.
TLDR
Nonlinear analysis of the COP time series supports the perspective that the development of postural control is a dynamic process whereby the infant learns to control the body's degrees of freedom to achieve the sitting posture.

TLDR
Evidence for the usefulness ofPhysiotherapy has yet to be demonstrated; with the presently available methodologies it is ethically imperative to institute a properly designed, collaborative, multicenter, randomized, controlled trial.
