Fig 3 Intersession reliability (ICC) for linear parameters of COP across months. Most linear parameter ICCs average around 0.5, and there is an increasing trend as the infant develops. This is not true for the mean sway path in which ICCs are presenting a decreasing trend across development.

Fig 4 Intrasession reliability (ICC) for linear parameters of COP across data-collection sessions. All linear parameters ICCs are averaging around 0.5, and there is an increasing trend as the infant develops.

Fig 5 Intersession reliability (ICC) for nonlinear parameters of COP across months. All nonlinear parameters ICCs are averaging lower than 0.5 except for LyE in both directions. Abbreviation: CoD, correlation dimension.
