The Neuro-sensory Motor Developmental Assessment Part 1: Development and Administration of the Test
Insights
The Neuro-sensory Motor Developmental Assessment (NSMDA) offers a progressive tool for evaluating infant and child development. This study validates the NSMDA’s predictability in assessing developmental status in preterm infants up to 24 months.
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.
Abstract:
The Neuro-sensory Motor Developmental Assessment (NSMDA) has been developed to meet the need for a progressive developmental assessment of infants and children. In this study a cohort of 148 preterm infants was assessed at 1, 4, 8, 12, and 24 months adjusted age. The results were used to classify the subjects as having normal, suspect or abnormal developmental status. The scores for each time were correlated with outcome scores at 24 months. Part One of this paper includes a description of the development and administration of the NSMDA. Longitudinal and cross correlations of scores were analysed and shown to be highly significant over the first two years of testing, thereby establishing the basis for validity and predictability of the NSMDA.
