The Infant Motor Profile (IMP) is a qualitative assessment of motor
behaviour in infancy. It consists of five domains: movement variation,
variability, fluency, symmetry, and performance. The aim of this study was to
assess interobserver reliability and concurrent validity of the IMP with the
Alberta Infant Motor Scale (AIMS) and an age-specific neurological examination.
METHOD: Fifty-nine preterm infants (25 females, 34 males; median gestational age
29.7wks, median birthweight 1285g) and 146 term infants (74 females, 72 males;
median gestational age 40.1wks, birthweight 3500g) were included. Assessments
were performed at corrected ages of 4, 6, 10, 12, and 18 months and consisted of
the IMP, AIMS, and an age-specific neurological examination. Interobserver
reliability was investigated on a sample of 25 video recordings. Non-parametric
statistics were used to analyse the data. RESULTS: Interobserver reliability was
high (intraclass correlation coefficient 0.95). At all ages, AIMS scores
correlated weakly to fairly with total IMP scores (Spearman's rho 0.36-0.55), but
moderately to strongly with scores on the performance domain of the IMP
(Spearman's rho 0.47-0.84). A clear relation was found between total IMP score
and outcome of the neurological examination (Kruskal-Wallis p<0.001 at all ages).
INTERPRETATION: Interobserver reliability of the IMP is good. Concurrent validity
with the AIMS is best for the IMP performance domain. Concurrent validity with
age-specific neurological examination is very good.
