The aim of this cross-sectional study was to provide normative data (ordinal
scores and timed performances) for gross and fine motor tasks in typically
developing children between 3 and 5 years of age using the Zurich Neuromotor
Assessment (ZNA). Method Typically developing children (n=101; 48 males, 53
females) between 3 and 5 years of age were enrolled from day-care centres in the
greater Zurich area and tested using a modified version of the ZNA; the tests
were recorded digitally on video. Intraobserver reliability was assessed on the
videos of 20 children by one examiner. Interobserver reliability was assessed by
two examiners. Test-retest reliability was performed on an additional 20
children. The modelling approach summarized the data with a linear age effect and
an additive term for sex, while incorporating informative missing data in the
normative values. Normative data for adaptive motor tasks, pure motor tasks, and
static and dynamic balance were calculated with centile curves (for timed
performance) and expected ordinal scores (for ordinal scales). Results
Interobserver, intraobserver, and test-retest reliability of tasks were moderate
to good. Nearly all tasks showed significant age effects, whereas sex was
significant only for stringing beads and hopping on one leg. Interpretation These
results indicate that timed performance and ordinal scales of neuromotor tasks
can be reliably measured in preschool children and are characterized by
developmental change and high interindividual variability.
