The PäPKi® screening sheet provides support in assessing motor skills of an infant from 0 to 12 months of age. Active postures from the spontaneous motor skills of a child are assessed. The age division was based on the Motor Assessment of the Developing Infant (average values of 2,200 children, Piper and Darrah 1994) and the Munich functional developmental diagnostics for the first year of life (average values of 1,660 children, Hellbrügge et al. 2002). In the PäPKi® screening sheet, the most important criteria of the individual stages of the neuromotor upright posture development process are presented in picture and keywords to check off.
