EFFECT OF SHOE MODIFICATIONS ON CENTER OF PRESSURE AND IN-SHOE PLANTAR PRESSURES1

American Journal of Physical Medicine & Rehabilitation, 1999
This study was conducted to determine the effect of footwear modification on patients with neuromusculoskeletal disorders. Two analyses, the center of pressure and the in-shoe plantar pressures, were studied with the help of healthy volunteers so that the effect of shoe modifications could be assessed.

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.

Biomechanical relationship between center of gravity and center of pressure during standing [PDF]

IEEE Transactions on Rehabilitation Engineering, 1994
The relationship between the position of a body's center of gravity (CG) as determined by a whole body kinematic model and that given by 3 CG position estimation techniques using the ground reaction force center of pressure (CP) has been investigated in this study. The CG and CP are related by the Newtonian mechanics equations of motion.

The Use of Pressure Plates for Static Center of Pressure Analysis in Horses

Journal of Equine Veterinary Science, 2015
Abstract Stabilographic analysis allows the quantification of balance by tracking center of pressure (COP) displacements in the horizontal plane during quiet standing. The aim of this study was to use pressure plates to measure descriptive stabilographic variables in Puro Sangue Lusitano horses.

High Pressure Characterization of Luminescence Centers in Oxides

2008
High pressure luminescence spectroscopy has been applied to three different Cr3+-doped oxides, LiTaO3 and LiSc(WO4)2 crystals and CaO-Ga2O3-GeO2 (CGGG) glasses. Using a pressure-induced 4T2-2E electronic crossover we observed and characterized a strong and intermediate inhomogeneous site distribution of Cr3+ in the host lattice series: CGGG-to-LiSc(WO4)

Dynamical structure of center of pressure fluctuations in elderly people

Gait & Posture, 2009
This study investigates whether aging has an influence on the dynamics of the fluctuations of the displacement of the center of pressure (COP), during quiet standing. Two groups of healthy subjects were compared (11 young and 12 elderly) for two visual feedback conditions (eyes open and eyes closed).

Pressure-Controlled Migration of Paramagnetic Centers in a Heterospin Crystal

Inorganic Chemistry, 2019
A study of the single-crystal-to-single-crystal transformation induced by temperature variation for the chain polymer Cu(II) complex with nitronyl nitroxide showed that an increase in the hydrostatic pressure of up to ∼0.07 GPa completely changes the intracrystalline displacements of molecules relative to one another.

Luminescence quenching inFcenters under pressure

Physical Review B, 1986
Pressure effects on F-center emission in KCl, KBr, KI, CsCl, CsBr, and CsI are observed under pressures ranging from 1 atm to 12 kbar at 1.6 K. In potassium halides the F-center emission shows a monotonic decrease with increasing pressure, while in cesium halides it shows an anomalous feature: It recovers and increases far beyond its value at 1 atm ...

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 ...

Ambulatory Center of Mass Prediction Using Body Accelerations and Center of Foot Pressure

IEEE Transactions on Biomedical Engineering, 2008
The center of body mass (COM), center of foot pressure (COP), and body segment acceleration signals are commonly used to indicate movement performance and stability during standing activities and walking. For balance maintenance and restoration, the human brain is capable of estimating and predicting the COM even in the absence of visual or vestibular ...
