Instability Prediction by Monitoring Center of Pressure During Standing
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Incorporating an instability predictor into a portable sensor has a number of clinically relevant applications. This study investigated the feasibility of developing a real-time assessment tool to predict stepping during standing by monitoring Center of Pressure (COP) measurements.

Microcantilevers Bend to the Pressure of Clustered Redox Centers
Langmuir, 2014The redox-activated deflection of microcantilevers has attracted interest for nanoactuation and chemical sensing. Microcantilever sensors are devices that transduce (bio)chemical reactions into a quantifiable nanomechanical motion via surface stress changes. Despite promising applications in analytical science, poor signal-to-noise ratios and a limited

On the center of pressure of a body
Fluid Dynamics, 1983It is shown that under conditions of local interaction of a flow with the surface of a body the position of the center of pressure does not depend on the angle of attack or the form of the model of the flow past the body for a large class of configurations including conical, cylindrical, spherical, and flat elements. The problem of finding the shape of

Detection of Gait Instability Using the Center of Mass and Center of Pressure Inclination Angles
Archives of Physical Medicine and Rehabilitation, 2006To define a parameter that quantifies balance control during gait and better identifies elderly people who are at a higher risk of falling.Controlled study.University research laboratory.Twelve elderly patients (mean age, 76.9+/-6y) with complaints of imbalance during walking, or with a history of falls, and 12 matched healthy elderly adults.Not ...

Dynamical structure of center of pressure fluctuations in elderly people
Gait & Posture, 2009This 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).

Variability of the center of pressure pattern integral during walking
Journal of the American Podiatric Medical Association, 1998The objective of this study was to measure the between-trial variability of the center of pressure pattern integral (COPPI) at the shoe-floor interface and within the shoe. Ten trials of the COPPI were recorded simultaneously at the shoe-floor interface and within the shoe as ten subjects walked over ground in standardized footwear and with two types ...

Management of Pressure Sores in a Specialty Center
Plastic and Reconstructive Surgery, 1979We report a study on the surgical management of 145 pressure sores in 115 patients treated in a spinal cord injury center. There is a definite trend toward better education of these patients, who do not develop their first pressure sores until years following the injury.

Aerodynamic Center and Center of Pressure of an Airfoil at Supersonic Speeds
Journal of the Aeronautical Sciences, 1947IT is WELL KNOWN that according to the Ackeret (or linearized) theory for supersonic flow both the aerodynamic center and the center of pressure of a symmetrical airfoil are always at the midpoint of the chord. It appears, however, that no general formulas have as yet been given for determining the aerodynamic center and center of pressure of a ...

On the center of pressure of conical bodies
Fluid Dynamics, 1980The profiles of conical bodies for which the position of the center of pressure in a supersonic flow with symmetry plane does not depend on the flow parameters are considered. The theoretical investigation of the aerodynamic characteristics of circular cones [1] has shown that their center of pressure does not depend on the angle of attack α when the ...
