centre of pressure in British Englishnoun1. physics the point in a body at which the resultant pressure acts when the body is immersed in a fluid 2. aeronautics the point at which the resultant aerodynamic forces intersect the chord line of the aerofoil Examples of 'centre of pressure' in a sentencecentre of pressure Postural control performance was estimated through variables calculated from centre of pressure movements.Centre of mass velocity and position, centre of pressure position, and disequilibrium torque were calculated.Arch index, centre of pressure position and medial-lateral heel peak force ratio were also evaluated.The force plate registered the deviations of the centre of pressure.Further, the expressions for friction and position of centre of pressure are obtained.Our purpose was to analyze the changes in centre of pressure trajectory using a force plate.Regarding the correlation analysis, correlations between pelvic acceleration and centre of pressure displacement were moderate-to-high (0.52≤r≤0.81).The centre of pressure of the sway was calculated, and separated into a slow (rambling) and fast (trembling) component. |
