Intra-and inter-examiner reliability of Alberta Infant Motor Scale application in follow-up ambulatory of at-risk newborns

ABSTRACT

Prematurity is a risk factor for delayed motor development, and it is recommended to monitor these infants in the first two years of life. To verify the properties of intra and inter-examiner measurements of AIMS in an outpatient follow-up clinic for newborns at risk in a public maternity hospital. Prospective study conducted in an outpatient follow-up of high-risk newborns. The Intraclass Correlation Coefficient (ICC) was used to analyze reliability. To compare the intra-examiner evaluations, the paired T-test or Wilcoxon test was performed. The independent T-test was used to compare inter-examiner assessments. The correlation between variables was analyzed using the Pearson or Spearman test. The Bland Altman test was performed to assess the concordance between the scores. 31 preterm infants with 8,47 ± 4,49 of corrected age were evaluated. There was no significant difference between the evaluations intra and inter-examiner. The ICC values remained above 0.88 for both intra and inter-examiner evaluation. The scores showed high agreement. AIMS has intra- and inter-examiner reliability for assessing and monitoring preterm newborns for up to 18 months in a follow-up clinic.
