AIM: The aim of this cross-sectional study was to provide normative data for
motor proficiency (motor performance and contralateral associated movements
[CAMs]) in typically developing children between 3 years and 18 years of age
using an updated version of the Zurich Neuromotor Assessment (ZNA-2). METHOD:
Six-hundred and sixteen typically developing children between 3 years and 18
years of age were enrolled from day-care centres, kindergartens, and schools, and
were tested using the ZNA-2 with improved items of the original battery. Motor
proficiency was assessed on five components (fine motor tasks, pure motor tasks,
static balance, dynamic balance, and CAMs) as a function of age and sex to
determine centile curves for each task. Intraobserver, interobserver, and
test-retest reliabilities were evaluated. RESULTS: Most ZNA-2 tasks featured a
marked developmental trend and substantial interindividual variability.
Test-retest reliability was generally high (e.g. static balance 0.67; CAMs 0.81;
and total scores 0.84). INTERPRETATION: The ZNA-2 is a reliable and updated test
instrument to measure motor proficiency in children from 3 to 18 years with
improved properties for assessing motor performance. It allows continuous
measurement without changing items for the entire age range; this feature of the
ZNA-2 is unique and makes the instrument suitable for clinical purposes. The
reduction of CAMs scoring simplifies the clinical procedure and increases its
reliability. WHAT THIS PAPER ADDS: The Zurich Neuromotor Assessment, Second
Edition (ZNA-2) provides new norms for motor proficiency in children between 3
years and 18 years. High reliabilities suggest that the revised test battery is a
useful tool for assessing neuromotor development. Integration of a 'not able to
perform' category makes the ZNA-2 suitable for clinical purposes.
