OBJECTIVES Footwear-generated biomechanical manipulations (e.g., wedge insoles) have been shown to reduce the magnitude of adduction moment about the knee. The theory behind wedged insoles is that a more laterally shifted location of the center of pressure reduces the distance between the ground reaction force and the center of the knee joint, thereby reducing adduction moment during gait.

BACKGROUND This pilot study aimed to assess the differences in center of pressure trajectory in neuropathic patients with steppage gait. Steppage gait has previously been evaluated by several biomechanical methods, but plantar pressure distribution has been much less studied. The purpose of this study was to analyze the changes in center of pressure trajectory using a force plate. METHODS The...

Abstract When an inverted pendulum approximates quiet standing, it is assumed that the distance between the center of pressure and the vertical projection of the center of mass on the ground (COP-COG) reflects the re...

Introduction:  Pressure  sores  refer  to  lesions  that  are  produced  while  a  constant  pressure  causes  necrotic  tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation  of  pressure  sores.  Modeling  the  mechanical  behavior  of tissue  will  provide  a better understanding  of this  process as well as a more suitable selection ...

Quiet standing balance and postural control are often assessed by drawing information from center of pressure (COP) data collected with a force platform. Efforts to better understand the underlying processes involved in postural control have lead to methods that examine the dynamic or stochastic characteristics of the COP. One method that has recently gained popularity is Stabilogram Diffusion ...

The "Tehran Blood Pressure Study" (TBPS) is an observational cross-sectional study performed on men and women aged 15 years or more during the years 1990-1991. The study has been designed and performed by the Tehran University of Medical Sciences' Cardiovascular Research Center, with the primary objective of determining the prevalence and distribution of high blood pressure in Tehrani adult...

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. The purpose of this study was to use the tools of Generalizability Theory (G-Theory) to investigate the reliability of COP m...
