The Neuro-sensory Motor Developmental Assessment Part 1: Development and Administration of the Test

Area of Science:

• Pediatric developmental assessment
• Neurodevelopmental disorders
• Infant motor skills evaluation

Background:

• The Neuro-sensory Motor Developmental Assessment (NSMDA) was created to address the need for a progressive developmental evaluation tool for infants and children.
• Preterm infants often exhibit developmental delays and require specialized assessment tools.

Purpose of the Study:

• To describe the development and administration of the NSMDA.
• To establish the validity and predictability of the NSMDA in preterm infants.
• To classify developmental status (normal, suspect, abnormal) in preterm infants.

Main Methods:

• A cohort of 148 preterm infants was assessed using the NSMDA at 1, 4, 8, 12, and 24 months adjusted age.
• Longitudinal and cross-correlations of NSMDA scores were analyzed.
• Scores were correlated with 24-month outcome scores.

Main Results:

• Longitudinal and cross-correlations of NSMDA scores demonstrated high significance over the first two years of testing.
• The NSMDA effectively classified subjects into normal, suspect, or abnormal developmental status categories.
• NSMDA scores showed significant correlation with 24-month outcome scores.

Conclusions:

• The NSMDA is a valid and predictable tool for assessing neuro-sensory motor development in preterm infants.
• The assessment provides a reliable method for tracking developmental trajectories from infancy through early childhood.
• The NSMDA supports early identification and intervention for infants at risk for developmental abnormalities.
