Foot Center of Pressure and Medial Knee Osteoarthritis

Journal of the American Podiatric Medical Association, 2010
Background: We sought to determine whether symptomatic medial knee osteoarthritis is associated with aberrant loading across the foot during gait. Methods: Twenty-five individuals with medial knee osteoarthritis were compared with 25 controls.

Complexity of Center of Pressure in Postural Control for Children With Autism Spectrum Disorders Was Partially Compromised.

Journal of Applied Biomechanics, 2019
The purpose of this study was to compare the complexity of postural control between children with autism spectrum disorder (ASD) and typical developing children during altered visual and somatosensory conditions using the multiscale entropy.

Center-of-Pressure Movements During Equine-Assisted Activities

The American Journal of Occupational Therapy, 2011
AbstractWe compared anteroposterior and mediolateral range of motion and velocity of the center of pressure (COP) on the horse’s back between riders without disabilities and riders with cerebral palsy. An electronic pressure mat was used to track COP movements beneath the saddle in 4 riders without disabilities and 4 riders with cerebral palsy ...

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.

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 ...

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.

Center of Pressure and Perceived Stability in Basketball Shoes With Soft and Hard Midsoles.

Journal of Applied Biomechanics, 2018
This study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements.

Center-of-Pressure Gates for Irrigation

Applied Engineering in Agriculture, 1991
Center-of-pressure gates, sometimes referred to as pressure gates, were developed and field tested to semi-automate basin and border irrigation systems. The gates use the principle of hydrostatic pressure distribution for operation and are constructed with a pivot shaft located at approximately one-third the water depth above the bottom of the gate ...

Linear sway-referencing control: center of pressure vs. center of mass

Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002
Sway-referenced control strategies based on center of pressure (COP) feedback and center of mass (COM) feedback were investigated using a linearly mobile platform (SLIP-FALLS). Four young adults (age range 24-32 years) were compared under the three sway test conditions: a fixed platform, a sway-referenced platform based on COP feedback, and a sway ...

The pressure distribution of hollow cathode centered negative pressure arc

Journal of Manufacturing Processes, 2016
Abstract As a newly modified welding heat source, hollow cathode centered negative pressure arc (HCCNPA) has obvious changes in arc morphology and pressure distribution in comparison with traditional gas tungsten arc (GTA). To better understand of these, in this paper the arc behavior was monitored by using a high-speed image processing system.
