Following a brief description of the uses, strengths and limitations of three earlier tests (Movement Assessment of Infants, Alberta Infant Motor Scale, Test of Infant Motor Performance), participants will be introduced to the Harris Infant Neuromotor Test (HINT), a reliable valid, and norm-referenced tool for screening low-risk (typically developing) or high-risk infants aged 2.5 to 12.5 months. A family-centered test, the HINT includes a questionnaire to examine the parent/primary caregiver’s opinions and level of concern about how their infant moves and plays. Although primarily a neuromotor screening test, the HINT also includes items aimed at identifying early cognitive or behavioral concerns, e.g., stereotypical behaviors, head circumference.

Relevance to Physiotherapy Practice

Through research conducted on the HINT, the test has been shown to: (1) corroborate the parent/primary caregiver’s level of concern about their infant’s movement and play; (2) discriminate between infants at low- and high-risk for developmental motor delay at 4, 5, 7, and 8 months; (3) correctly identify infants who do not have a neuromotor delay; (4) have predictive correlations equal to or slightly greater than those for the Alberta Infant Motor Scale (AIMS); and (5) categorize infants’ levels of motor delay (within normal limits, mild delay, significant delay) the same as with the Bayley-II Motor Scale.

Target Audience

Paediatric PTs/PTAs who work with infants in clinical, research or academic settings who wish to learn more about infant assessment/screening.


Upon completion of this workshop participants will be able to:

(1) Identify the purposes, strengths and limitations of the Movement Assessment of Infants (MAI), Alberta Infant Motor Scale (AIMS), and Test of Infant Motor Performance (TIMP).

(2) Describe the purpose, age range, intended population and qualifications of those who can administer and score the HINT.

(3) Trace the development of the HINT including reliability, concurrent and predictive validity and standardization.

(4) List 5 conclusions based on HINT research regarding maternal educational differences, ethnic differences, the validity of using the HINT for US infants, and comparisons to the AIMS.

(5) Discuss a clinical case example of a 9.5-month-old infant referred because of maternal developmental concerns and assessed on the HINT and Bayley-II.


Susan HarrisPT, PhD, FCAHS

A Professor Emerita in the Department of Physical Therapy in the Faculty of Medicine at UBC, Susan is the former Editor-in-Chief of Physiotherapy Canada and currently serves on the editorial board of Infants & Young Children. Her paediatric research has focused on early diagnosis of movement disorders in infants and the effectiveness of early intervention for at-risk infants and children with neurodevelopmental disabilities. She is co-author, with Dr. Marci Hanson, of Teaching the Young Child with Motor Delays: A Guide for Parents and Professionals (1986), primary author of the 2009 manual for the Harris Infant Neuromotor Test (HINT), and has authored/co-authored more than 160 peer-reviewed journal articles.

The Paediatric Division is a special interest group within the Canadian Physiotherapy Association. Our membership consists of clinicians from all practice settings, students, educators, researchers, physiotherapy assistants and administrators all of whom have a passion for promoting participation and enhancing the lives of children and their families. We are dedicated to provide resources and information for paediatric patients and their families to promote participation and function independence in all aspects of life.
