Center of Pressure Posturography
Center of pressure (CoP) posturography measures postural stability by analyzing the movement of the body's center of pressure—the point where the total force of body weight is concentrated—during quiet stance or dynamic balance tasks. Formalized by Duarte and colleagues (2000), CoP analysis provides quantitative metrics of postural sway including sway area, path length, and velocity. These measurements reflect the integrated function of sensory systems (proprioception, vestibular, visual), central integration, and motor control. CoP posturography is widely used in neurology, vestibular medicine, rehabilitation, and sports science to detect balance deficits and monitor recovery.
