Table 4 demonstrates a significant association between the presence/absence of fidgety movements and the PDMS-2 scores, although we also found five infants (9.3%) with fidgety movements who scored poorly in the 1-year PDMS-2 assessment (Table 5). By incorporating the optimality criterion, the proportion of individuals who remained undetected could be further reduced to 5.6%. Hence, the assessment of the additional motor repertoire (postures and movements other than fidgety movements) adds to the assessment of fidgety movements. Apart from an early identification of infants at high risk for motor dysfunctions, a careful and detailed evaluation of movement and postural patterns enables us to find strengths and limitations in each child that might induce individual intervention strategies.
