Stochastic processes in postural center-of-pressure profiles

Experimental Brain Research, 1997
The stochastic processes of postural center-of-pressure profiles were examined in 3- and 5-year-old children, young adult students (mean 20 years), and an elderly age group (mean 67 years). Subjects stood still in an upright bipedal stance on a force platform under vision and nonvision conditions.

On the center of pressure of a body

Fluid Dynamics, 1982
It is shown that under conditions of local interaction of a flow with the surface of a body the position of the center of pressure does not depend on the angle of attack or the form of the model of the flow past the body for a large class of configurations including conical, cylindrical, spherical, and flat elements. The problem of finding the shape of

Deception effects on standing center of pressure

Human Movement Science, 2014
Accurate deception detection is a desirable goal with many applications including credibility assessment, security screening, counter-terrorism, and homeland security. However, many deception detection methodologies involve intrusive sensors or other limitations that preclude their use in a covert manner. Posturography may overcome these limitations by

The Center of Pressure Path in Treated Clubfeet

Clinical Orthopaedics and Related Research, 1981
The center of pressure paths of foot-floor contact were examined in detail in normal subjects and a group of 44 patients with treated clubfeet. The foot-floor contact areas were wide and the center of pressure paths more variable in clubfeet patients.

Reliability and Validity of Center-of-Pressure Quantification

Journal of the American Podiatric Medical Association, 2003
The purpose of this study was to determine the reliability and validity of two center-of-pressure quantification methods. One hundred five individuals (33 men and 72 women) with a mean age of 26.7 years participated in phase 1 of the study. Two measures of the center-of-pressure pattern, the lateral-medial area index and the lateral-medial force index,

Velocity of the center of pressure during walking

Journal of the American Podiatric Medical Association, 2000
The purpose of this study was to describe the velocity of the center of pressure during walking in a sample of young, healthy individuals. The velocity of the center of pressure was recorded in 60 subjects while they walked barefoot over a floor-mounted pressure platform.

Asymmetric dynamic center-of-pressure in Parkinson's disease

Journal of the Neurological Sciences, 2020
Gait disturbance gradually worsens as Parkinson's disease (PD) progresses, which significantly affects the quality of life of PD patients. Treadmill-based gait analysis systems can measure gait parameters including the dynamic center-of-pressure (COP) trajectory during ambulation.

Research on the pressure field of hydrostatic center rest

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
Pressure distribution of heavy type hydrostatic center rest used in the heavy CNC equipment is hard to be measured directly because the oil film is very thin in the practical engineering. In order to solve this problem, a simulation research concerning the pressure field of hydrostatic center rest is described.

Evaluation of plantar pressures and center of pressure trajectories in Adolescent Idiopathic Scoliosis

2021
Adolescent idiopathic scoliosis (AIS) has been postulated to affect gait patterns and postural stability due to its effect on center of body mass. 1) Determine the correlation between Cobb angle and COP in the anterior-posterior (AP) direction, COP in the medial-lateral (ML) direction, COP oscillation (COP-O) from midline walking, peak pressures, and ...

Generalizability of center of pressure measures of quiet standing

Gait & Posture, 2007
Center of pressure (COP) measures are commonly used as indicators of balance and postural control. At present, there are no universally accepted standards in research investigating fluctuations in the COP with regard to the number of trials or the length of a given trial.
