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.

Fatigue Increases Center of Pressure Sway

Medicine & Science in Sports & Exercise, 2019
1.60 ± 1.05 s, p = 0.22), but greater at POST compared to PRE on ND (1.21 ± 0.51 vs 1.60 ± 0.58 s, p = 0.04). The between-day TE assessed using PRE TTS from session 2 and 3 was 0.36 s on D and ND.

Early Detection of Parkinson’s Disease Using Center of Pressure Data and Machine Learning

Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2021
Parkinson’s disease (PD) is a progressive neurodegenerative disorder resulting in abnormal body movements. Postural instability is one of the primary motor symptoms of PD and contributes to falls.

Effect of Center of Mass Immobilization on Center of Pressure Displacement in Single and Dual-Task

Journal of Motor Behavior, 2021
Recent research showed that artificially immobilizing the center of mass (COM) of participants in a standing position increased the center of pressure (COP) variability. This increase has been interpreted as an exploratory behavior.

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

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,

Alterations in center of pressure during single limb loading in individuals with patellofemoral pain.

Journal of the American Podiatric Medical Association (Print), 2020
BACKGROUND Altered foot loading during weight bearing is suggested to play a role in the development of patellofemoral pain (PFP). This study aimed to determine foot loading characteristics associated with PFP by assessing center of pressure (COP) during

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.

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.
