Hand function in children with unilateral spastic cerebral palsy

Area of Science:

• Neurology
• Pediatrics
• Radiology

Background:

• Unilateral spastic cerebral palsy (US CP) affects hand function in children.
• Understanding the relationship between neuroimaging and hand function is crucial for diagnosis and prognosis.

Purpose of the Study:

• To assess hand function in children with US CP using the Manual Ability Classification System (MACS).
• To explore the correlation between neuroimaging findings and hand function levels in this population.

Main Methods:

• Hand function was evaluated using MACS (I-V) in 114 children with US CP.
• Brain lesions were categorized into groups: maldevelopment (MAL), periventricular white matter (PV WM), cortical/subcortical gray matter (C/SC GM), and others.
• Neuroimaging techniques included Computed Tomography (CT) and Magnetic Resonance Imaging (MRI).

Main Results:

• A significant association was found between mild hand dysfunction (MACS I and II) and PV WM lesions (p=0.001).
• MRI revealed PV WM lesions in 48.9% of cases, C/SC GM in 29.8%, and MAL in 8.5%.
• Mild hand dysfunction (MACS I and II) was observed in 59.7% of the children studied.

Conclusions:

• Mild hand dysfunction in children with US CP is significantly associated with PV WM lesions.
• The type of brain lesion identified through neuroimaging can aid in determining lesion timing and predicting the severity of hand dysfunction.
