A review of center of pressure (COP) variables to quantify standing balance in elderly people: Algorithms and open‐access code
Postural control is often quantified by recording the trajectory of the center of pressure (COP)—
also called stabilogram—during human quiet standing. This quantification has many …

Controlling human upright posture: velocity information is more accurate than position or acceleration
The problem of how the nervous system fuses sensory information from multiple modalities
for upright stance control remains largely unsolved. It is well established that the visual …
