A Velostat-Based Pressure-Sensitive Mat for Center-of-Pressure Measurements: A Preliminary Study [PDF]
International Journal of Environmental Research and Public Health, 2021 Center-of-pressure (CoP) displacements play a key role in studies assessing postural stability. The accepted instrument to measure CoP trajectories is the force platform, but pressure-sensitive mats (PSMs) are an alternative composed of a matrix of sensitive cells. A typical cell comprises two electrodes with piezoresistive material in between, while a

Circular Components in Center of Pressure Signals
Motor Control, 2013 Static posturography provides an objective assessment of postural control by characterizing the body sway during upright standing. The center of pressure (COP) signal is recorded by a force platform, and it is analyzed by means of many different models and techniques.

Quantifying center of pressure variability in chondrodystrophoid dogs [PDF]
The Veterinary Journal, 2017 The center of pressure (COP) position reflects a combination of proprioceptive, motor and mechanical function. As such, it can be used to quantify and characterize neurologic dysfunction. The aim of this study was to describe and quantify the movement of COP and its variability in healthy chondrodystrophoid dogs while walking to provide a baseline for ...

An integrated dual-wave ultrasonic apparatus based on solid-state coupling for complete elastic characterization [PDF]
AIP AdvancesAccurate determination of elastic moduli remains challenging for brittle and surface sensitive materials. Traditional ultrasonic techniques rely on liquid coupling media, which impedes shear wave transmission, and require complicated phase corrections ...

Structural transitions of 4:1 methanol–ethanol mixture and silicone oil under high pressure
Matter and Radiation at Extremes, 2021 A 4:1 (volume ratio) methanol–ethanol (ME) mixture and silicone oil are two of the most widely used liquid pressure-transmitting media (PTM) in high-pressure studies.

Monitoring Of The Center Of Pressure In Unipedal Support In Karate
المجلة العلمية العلوم والتكنولوجية للنشاطات البدنية والرياضية, 2021 Stabilometry is a technique for analyzing posture based on recording the oscillations of a subject's center of pressure (COP) on an instrumented platform. Under unusual or destabilizing conditions, maintaining postural activity requires the establishment of rapid motor reactions.
