Limited motor performance and minor neurological dysfunction at school age.

Area of Science:

• Developmental Pediatrics
• Neuroscience
• Motor Control

Background:

• Minor neurological dysfunction (MND) affects motor development in children.
• Understanding the link between MND and motor performance is crucial for early intervention.

Purpose of the Study:

• To investigate the relationship between motor performance and minor neurological dysfunction (MND) in school-aged children.
• To identify specific types of MND that most impact motor skills.

Main Methods:

• Neurological examination of 253 children (mean age 8y 7mo) using Touwen criteria.
• Assessment of motor performance via Movement Assessment Battery for Children (MABC), DCD-Q, and MOQ-T.
• Analysis of MND severity (simple/complex) and type of dysfunction.

Main Results:

• Motor performance scores (MABC, DCD-Q, MOQ-T) strongly correlated with MND severity, coordination, and fine manipulation deficits.
• Mild posture and muscle tone dysfunctions showed a weaker link to motor performance limitations.
• Children with MABC scores below the 5th percentile exhibited complex MND more frequently (54%) compared to higher percentiles.

Conclusions:

• Limited motor performance in children is associated with the severity and type of minor neurological dysfunction.
• Coordination problems and fine manipulative disabilities are key indicators of poor motor performance.
• Mild postural and muscle tone issues have a less pronounced effect on overall motor skills.
