Transcript of Copy of Alberta Infant Motor Scale (AIMS)

Motor Assessment of the Developing Infant
Alberta Infant Motor Scale
Martha C. Piper, Ph.D.
Johanna Darrah, M.Sc., P.T.
Prevailing Theories of Motor Development
Neuromaturational Theory
Systems Theory (Bernstein)
Motor development occurs due to maturation of the CNS ("top-down influence")
Then what is the point of therapy?!
Motor behaviors are a product of all contributing subsystems
Development is non-linear
Before the AIMS there was...
Bayley Scales of Infant Development

Movement Assessment of Infants

Peabody Developmental Motor Scales

Gross Motor Function Measure

Pediatric Evaluation of Disability Inventory

**Less formal measurements: primitive reflexes, observation of spontaneous motor behavior
Why do we need
outcome measure?!
**AIMS (1994)**
"Currently, no appropriate measures of infant motor maturation exist to assist therapists in the
identification of infants who are developing normally versus those who are experiencing abnormal patterns of maturation and may require intervention."

ICF Model
Activities and Participation
Changing basic body position (e.g. turn in bed, sit up, stand)

Maintaining a body position (e.g., control head position)

Using hands and arms (e.g., grasp and pick up objects)

Moving around (e.g., crawl, scoot, climb stairs, run and jump)
Body Function

Spontaneous movements. (This is about the infant’s movements and changes of body positions)

Postural, balance or threatening reactions (supporting, self-protecting and defensive reactions)
Administration Guidelines
Age & type of client
Identification of motor delays (ALL infants, 18 months or younger)
Evaluation of motor development over time (Infants 18 months or younger without abnormal patterns of movement)

Observational approach
Minimal handling!
Observation of spontaneous movements

Infant's state
Awake, active, and content!
Infant should be naked, if possible
Exam terminated if infant can't be comforted

Does not matter, as long as all positions assessed
Clinic or at home in a warm, quiet room
Young infant: examining table, >4 months: mat or carpeted area
Parental Involvement
Should be present and undress infant
May comfort and position the infant (when needed)
Visual and auditory prompts may be used (parent or PT)
Some infants may require positioning
Time requirements
"20-30 minutes"
Materials needed
Examining table (0-4 months)
Mat or carpeted area (>4 months)
Age appropriate toys
Stable wooden bench/chair
AIMS score sheet and graph
Composed of 4 subscales:
Prone (21 items)
Supine (9 items)
Sit (12 items)
Stand (16 items)

Prone Subscale
Prone lying (1)
Prone lying (2)
Prone prop
Forearm support (1)
Prone mobility
Forearm support (2)
Rolling prone to supine w/out rotation
Reaching from forearm support
Rolling prone to supine w/ rotation
Four-point kneeling (1)
Propped lying on side
Reciprocal crawling
Four-point kneeling to sitting or half sitting
Reciprocal creeping (1)
Reaching from extended arm support
Four-point kneeling (2)
Modified four-point kneeling
Reciprocal creeping (2)
Dichotomous: observed or NOT observed
To be scored AFTER assessing

"Window" of skills
Least mature and most mature
items identified
All items within window must be scored
No assumptions or parent report!
Bidirectional motor items at the discretion of evaluator (i.e. rolling)
Score Sheet
Prone lying (1)
Prone lying (2): Observed
Prone prop: Not observed
Forearm support (1): Observed
Prone mobility: Observed
Forearm support (2)
"Window" of skills
Let's score the prone subscale!
What prone skills did you observe?

Marty is 2 months old. If he received a
AIMS score of 10, would you be concerned about his motor development?

Supine Subscale
Supine lying (1)
Supine lying (2)
Supine lying (3)
Supine lying (4)
Hands to knees
Active extension
Hands to feet
Rolling supine to prone without rotation
Rolling supine to prone with rotation
Distinguishing between different types of supine lying (1-4)
Sit Subscale
Sitting with support
Sitting with propped arms
Pull to sit
Unsustained sitting
Sitting with arm support
Unsustained sitting w/out arm support
Weight shift in unsustained sitting
Sitting w/out arm support (1)
Reach with rotation in sitting
Sitting to prone
Sitting to 4-pt kneeling
Sitting w/out arm support (2)
Establish a skill "window"
Sitting with support

Sitting with propped arms (Observed)

Pull to sit

Unsustained sitting

Sitting with arm support

Unsustained sitting without arm support

Weight shift in unsustained sitting (Observed)

Sitting without arm support (1)
What would you do next while doing an AIMS assessment?
Stand Subscale
Supported standing (1)
Supported standing (2)
Supported standing (3)
Pulls to stand with support
Pull to stand/stands
Supported standing with rotation
Cruising without rotation
Controlled lowering from standing
Cruising with rotation
Stands alone
Early stepping
Standing from modified squat
Standing from quadruped position
Walks alone
Watch the following videos and determine which level of supine lying the infant demonstrates.

Work together!
Distinguishing between different types of supported standing
Watch the following video and determine what level of supported standing Marty is at!
Work together!
Purpose of the AIMS
infants with abnormal
motor development

infants with delayed motor development over time (excluding those with abnormal movement patterns)
**Hint: Use the percentile ranks in your record booklets!
In the movie you just watched,
what was the infant's least mature
and most mature
**Total AIMS score are calculated by**
adding the subscale scores together.
Interpreting your AIMS score
Percentile ranks can be determined using the infant's AIMS score and their age (months.)
