Establish normative value of Alberta infant motor scale in Pune population

Background: The Alberta infant motor scale (AIMS) is a norm-reference test that assessed the spontaneous motor performance of infant 0-18 month. AIMS is development, motor assessment tools in the evaluation of motor risk in infants, but this scale was formulated by using western samples. In every country various differences are observed in the culture and ethnicity. Therefore, there is a need to establish normative value of AIMS in Pune population. Aim of the study was to establish normative value of AIMS in Pune population.

Methods: A descriptive one time study of 420 healthy infants aged between 0 to 18 months was included in the study. Infants were observed in prone, supine, sitting, and standing positions. Infants were measured using the AIMS test and represent normative value in Pune population.

Results: Medcalc software was used for the statistical analysis. For each month we calculated the mean AIMS score, and standard deviation, as well as percentiles. 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. Pune infants demonstrated lower scores in specific ages compared to the Canadian sample.

Conclusions: Although the AIMS is used in both research and clinical practice, it has certain limitations in terms of behavioral differentiation before 2 months and after 15 months. This reduced sensitivity at the extremes of the age range may be related to the number of motor items assessed at these ages’ months.
