Harris Infant Neuromotor Test: comparison of US and Canadian normative data and examination of concurrent validity with the Ages and Stages Questionnaire.

Background: The Harris Infant Neuromotor Test (HINT) was developed as a screening tool for potential motor and cognitive developmental disorders in infants. Scoring on the HINT has been shown to be reliable, and several studies have supported the validity of the HINT. Normative values for the tool have been developed using Canadian infants.
