Brain structural alterations correlate with motor dysfunction in children with spastic cerebral palsy: a quantitative...

Area of Science:

• Neuroimaging
• Pediatric Neurology
• Developmental Neuroscience

Background:

• Spastic cerebral palsy (CP) is a prevalent childhood motor disability resulting from non-progressive brain injury.
• Understanding the relationship between brain structure and motor deficits is crucial for effective management.

Purpose of the Study:

• To investigate the correlation between quantitative brain Magnetic Resonance Imaging (MRI) parameters and motor dysfunction in children with spastic CP.

Main Methods:

• Recruited 91 children with spastic CP and 91 controls.
• Measured brain volumes using high-resolution T1-weighted MRI.
• Assessed gross motor function with the Gross Motor Function Measure-66 (GMFM-66) and muscle tone using the modified Ashworth scale.

Main Results:

• Children with spastic CP exhibited significantly lower total brain volume, white matter volume, gray matter volume, and white matter/total brain volume ratio compared to controls.
• White matter volume and the white matter/total brain volume ratio positively correlated with GMFM-66 scores in children with spastic CP.
• Muscle tone in specific muscles showed a negative correlation with brain volumes.

Conclusions:

• White matter volumes are strongly associated with motor dysfunction in pediatric spastic CP.
• Quantitative MRI offers objective biomarkers for assessing spastic CP severity and prognosis.
• Findings support the development of individualized rehabilitation strategies for spastic CP.
