RESUMEN
PURPOSE: To investigate the relationships among the Infant Motor Profile (IMP), the Neuro-Sensory Motor Developmental Assessment (NSMDA), and the Alberta Infant Motor Scale (AIMS) in prematurely born infants. METHODS: Sixty-one preterm infants with a birth weight under 2500 g were assessed by the IMP, the NSMDA, and the AIMS. RESULTS: There was a significant correlation between the IMP total score and the AIMS percentile and between the IMP total score and the NSMDA functional levels. There were significant correlations between the AIMS percentile age and the NSMDA functional levels and between the AIMS total scores and the IMP total scores. In the infants with atypical development, the relationship was significant between the AIMS and the IMP; however, there was no relationship between the IMP and the NSMDA. CONCLUSIONS: The 3 movement analysis tests are related. The IMP was found to be consistent with other movement analysis tests.
