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.

Validating Center-of-Pressure Balance Measurements Using the MatScan® Pressure Mat

Journal of Sport Rehabilitation, 2018
Context: Measurements of center-of-pressure (COP) excursions during balance are common practice in clinical and research settings to evaluate adaptations in postural control due to pathological or environmental conditions. Traditionally measured using laboratory force plates, pressure-mat devices may be a suitable option for clinicians and scientist to

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.

Analyzing center of pressure progression during bed exits

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
This paper presents a new approach for analyzing center of pressure (COP) progression using pressure data collected from a pressure-sensitive array placed under the bed mattress. Pressure data were collected from a young female participant who was healthy and an older 78 year old female participant who had a history of falls.

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.

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.

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 ...
