Gross motor trajectories of pre-term and full-term infants under different parental educational approaches

Abstract

This study aimed to explore motor trajectories of Brazilian pre-term and full-term infants from 3 to 12 months old whose parents participated in an educational program and had received guidance on gross motor development. Forty-eight Brazilian infants aged 3 months old were divided into Group 1 (full-term infants and their parents who received only verbal guidance, n = 14), Group 2 (full-term infants with parents who received an educative folder in addition to the same verbal guidance, n = 23), and Group 3 (preterm infants with parents who received the same verbal guidance and educative folder, n = 11). The folder had similar information to the verbal guidance; nonetheless, it helped to teach parents and allowed later consultation at home. We applied Alberta Infant Motor Scale, Affordances in Home Environment for Motor Development–Infant Scale, and a questionnaire about infants’ information at 3-, 6-, 9-, and 12-months old. In longitudinal comparison, all groups showed a significant difference for AIMS variables on total score and subscales; all subitems of AHEMD-IS; and time spent in prone, supine, sitting, and standing positions. In general, no differences were found between groups. Motor trajectory, home opportunities, and parental positioning practices were similar between full-term and preterm infants with different guidance approaches.
