Alberta Infant Motor Skills (AIMS)

Author: Piper, M.C., Darrah, J.

Summary: The AIMS assesses through observation infants who are delayed or atypical in their motor performance and evaluates motor development over time (Piper & Darrah, 1994).
Format: 58 item, performance-based, norm-referenced, observational tool.

Library Record:  Call #  WE 103 P665m 1993 ATOOLS  (Reserve Desk)



Identification of Motor Delays:

  • All infants aged18 months or younger.

Evaluation of Motor Development Over Time:

  • All infants, 18 months or younger, except those with abnormal patterns of movement.
  1. Infants with normal motor development that are being monitored over time as part of their develomental history.
  2. Infants at risk for developmental delays.
  3. Infants who have been diagnosed with disorders or conditions causing delayed motor development (e.g. fetal alcohol syndrome, Down syndrome, failure to thrive, seizure disorders, bronchopulmonary dysplasia, and developmental delay).
  4. Infants with no predisposing factors whose motor development is identified as being immature or suspect through a routine physical examination.

AIMS should not be used to evaluate older children whose motor abilities are still at the infant level (Piper & Darrah, 1994).

Completion time     20 to 30 minutes


  • examining table for younger infants (0 to 4 months)
  • mat or carpeted area for older infants; the mat should be firm enough that it does not impede the infant's ability to move
  • toys appropriate for ages 0 to 18 months
  • stable wood bench or chair to observe some of the pull to stand, standing, and cruising items in the standing subscale.
  • AIMS score sheet and graph.

Setting: in the clinic or home; warm quiet room is desirable.

Infant state: whenever possible, the infant should be naked for the assessment; infant should be awake, active and content during assessment.

Parental involvement: Parent or caregiver should be present during assessment and should undress the infant; parent should comfort the infant if anxious.
