Manual skill, hand skill asymmetry, and neuropsychological test performance in schoolchildren with spastic cerebral...

Area of Science:

• Neuroscience
• Developmental Psychology
• Rehabilitation Medicine

Background:

• Spastic cerebral palsy (CP) affects motor function, with varying impact on hand skills.
• Understanding the relationship between hand function and cognitive abilities in children with CP is crucial for targeted interventions.

Purpose of the Study:

• To investigate the association between bilateral hand skill deficits and neuropsychological performance in children with spastic cerebral palsy.
• To determine if the side of hemiplegia or overall hand impairment is more predictive of cognitive deficits.

Main Methods:

• A computerised Peg Moving Task assessed bilateral hand skills in 30 children (7-8 years) with spastic CP (diplegia, right hemiplegia, left hemiplegia) and 30 controls.
• Neuropsychological testing evaluated oral repetition, visual-motor skills, phonological awareness, visuospatial abilities, and counting.

Main Results:

• Children with CP showed impairments in oral repetition and visual-motor tasks compared to controls.
• Hemiplegic children (30%) had unaffected hand impairment; diplegic children (70%) had bilateral hand impairment.
• Right hand impairment correlated with phonological skills; left hand impairment correlated with visuospatial and counting skills.

Conclusions:

• Impairment in hand function, irrespective of the affected side, is associated with neuropsychological deficits in children with CP.
• Hand skill deficits significantly impact the ability to perform daily living manual activities.
• Interventions should focus on improving overall hand function to address associated cognitive challenges.
