Insights

The Alberta Infant Motor Scale (AIMS) is reliable for assessing gross motor skills in Brazilian preterm and term infants. This study confirms its validity for use in diverse infant populations.

Area of Science:

  • Pediatrics
  • Motor Development
  • Reliability Studies

Context:

  • Assessing gross motor development in infants is crucial for early identification of developmental delays.
  • The Alberta Infant Motor Scale (AIMS) is a widely used tool for evaluating infant motor skills.
  • Understanding the reliability of the Brazilian version of the AIMS in preterm and term infants is essential for clinical practice in Brazil.

Purpose:

  • To analyze the intraclass reliability of the Brazilian version of the Alberta Infant Motor Scale (AIMS).
  • To evaluate the AIMS's consistency across different gestational ages (preterm and term infants).
  • To determine the AIMS's suitability as a reliable tool for assessing gross motor performance in Brazilian infants.

Summary:

  • A methodological study involving 50 preterm and term infants in Fortaleza, Ceará, Brazil, assessed the intraclass reliability of the AIMS.
  • Three evaluators assessed infants in various positions (prone, supine, sitting, standing) and overall scores.
  • Intraclass correlation indices for most categories and total scores were high (above 0.800), indicating good reliability, with some variation in the standing category.

Impact:

  • The findings support the use of the Brazilian AIMS as a reliable instrument for evaluating gross motor development in both preterm and term infants.
  • This study provides evidence for the AIMS's applicability in the Brazilian context, aiding clinicians and researchers in motor assessment.
  • The results contribute to the validation of the AIMS for diverse infant populations, enhancing its global utility.
