A review of center of pressure (COP) variables to quantify standing balance in elderly people: Algorithms and open‐access code
Postural control is often quantified by recording the trajectory of the center of pressure (COP)—
also called stabilogram—during human quiet standing. This quantification has many …

Influential factors in stability of lower-limb amputees
Objective Lower-limb amputation is mainly a result of trauma, vascular disease, diabetes, or
congenital disorders. Persons with amputation lose their ability to stand and walk on the …

To freeze or not to freeze? Affective and cognitive perturbations have markedly different effects on postural control
Similar effects have been reported for diverting attention from postural control and increased
anxiety on the characteristics of center-of-pressure (COP) time series (decreased excursions …

Detection of postural control in early Parkinson's disease: Clinical testing vs. modulation of center of pressure
Introduction Little is known about the early stage balance changes in PD. Many clinicians
assume that there are no postural issues in early PD because of failure to identify them on …

Frequency analysis approach to study balance control in individuals with multiple sclerosis
Background The ability to control balance is often compromised in people with multiple
sclerosis (MS) and is considered to be a strong contributing factor toward their increased risk …

Specific posture-stabilising effects of vision and touch are revealed by distinct changes of body oscillation frequencies
We addressed postural instability during stance with eyes closed (EC) on a compliant
surface in healthy young people. Spectral analysis of the centre of foot pressure oscillations …

Distinguishing among standing postures with machine learning-based classification algorithms
The purpose of our study was to evaluate the accuracy with which classification algorithms
could distinguish among standing postures based on center-of-pressure (CoP) trajectories …

Evaluation of the temporal structure of postural sway fluctuations based on a comprehensive set of analysis tools
M Kirchner, P Schubert, D Schmidtbleicher… - Physica A: Statistical …, 2012 - Elsevier
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 …

Motor subtypes of Parkinson's disease can be identified by frequency component of postural stability
Parkinson's disease (PD) can be divided into two subtypes based on clinical features—
namely tremor dominant (TD) and postural instability and gait difficulty (PIGD). This …

Concussion history associated with increased postural control deficits after subsequent injury
Objective: Postural control deficits have been extensively reported following sport-related
concussions. Concussed athletes demonstrate these deficits as early as 24 h post …
