Introduction:
The lack of Brazilian norms restrains the use of the Alberta Infant Motor Scale (AIMS) to precisely categorize infant motor development and discriminate infants with motor difficulties from typically developing infants.
Objective:
This study investigated reference values for the AIMS for Brazilian infants.
Methods:
Descriptive, cross-sectional study of infants from birth-to-18 months old. Trained professionals assessed infants in daycares, homes, and governmental health centers.
Results:
Results showed increases in raw scores across age groups from 0- to 15-months of age. The stability of raw scores was observed after 16 months of age. Brazilian infants demonstrated lower scores in specific ages compared to the Canadian sample.
Conclusions:
Canadian and Brazilian children showed differences in motor performance scores across age and norms were established for Brazilian infants. This study highlights the importance to establish reference values for AIMS of infants across cultures.

Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
