Is the Test of Infant Motor Performance (TIMP) a valid assessment tool for infants less than 4 months of age and can scores on the TIMP predict school age motor development? Physical therapists in outpatient settings have been treating preterm infants as early as 3 weeks and are considering using the TIMP instead of the Peabody Development Motor Scale (PDMS) or the Bayley Scale of Infant Development (BSID) as an assessment tool for infant motor development. The PDMS is a valid assessment tool of children from birth to 60 months and the BSID is a valid assessment tool of children from 1 month to 42 months; however, both tests fail to predict school age motor development for infants less than 3 months of age.1
Can the TIMP predict an infant’s risk of motor developmental delay at school age, to determine which infants would benefit from early physical therapy interventions?
Clinical Bottom Line
Based on the results found by Flegel et al. and Kolobe et al. the Test of Infant Motor Performance accurately predicts school age motor development on the Bruininks-Oseretky Test of Motor Proficiency and the Peabody Developmental Motor Scales, 2nd edition. The TIMP can be used as an assessment tool to determine which infants would benefit from early physical therapy interventions.
