Investigation of the relationship between gross motor maturation from 1 to 18 months and preschool gross motor performance in at-risk infants.

Background: At-risk infants are predisposed to major and minor neurodevelopmental disorders due to various biological and environmental factors.

Objective: This study aimed to investigate the relationship between gross motor maturation from 1 to 18 months and gross motor performance in the preschool period, as well as the risk of developmental coordination disorder (DCD) in at-risk infants, referred to the Family Counselling Center of the Turkish Spastic Children's Foundation (FCCTSCF) between 2014 and 2016.

Methods: Fifty-seven children who had their gross motor maturation assessed between 1 and 18 months at the FCCTSCF were re-evaluated in the preschool period. The Alberta Infant Motor Scale (AIMS) was used to evaluate gross motor maturation between 1 and 18 months. In contrast, the Gross Motor Function Measure-88 and the Developmental Coordination Disorder Questionnaire were used to assess gross motor performance in the preschool period.

Results: Of the at-risk infants included in the study, 45.6% were evaluated as having typical development, 21% were identified as having cerebral palsy (CP), and 33.3% were determined to be at risk for DCD. Children with CP and those at risk for DCD were found to have lower percentile ranks on the past AIMS test compared to the healthy group (p = 0.001). A significant positive correlation was found between the Alberta Infant Motor Scale and the Gross Motor Function Measure-88 (p = 0.014).

Conclusion: In the clinical follow-up of at-risk infants, those who scored low on AIMS should be monitored for future risk of DCD and minor disorders, even if major neurological issues such as cerebral palsy are not detected.
