Hypothesis
Reaching accuracy in children with CP would be lower than in typically developing children and would be related to PFC activity.
Conclusion
Children with cerebral palsy showed lower reaching accuracy and altered prefrontal cortex activity compared to typically developing peers during a robotic reaching task.
Supporting Evidence
- Children with CP displayed lower reaching accuracy compared to controls.
- Greater deficits were observed in the non-preferred arm than the preferred arm.
- PFC activity differed across groups during preferred arm reaching.
- Children with CP exhibited lower PFC activity under high time constraints compared to low time constraints.
Takeaway
Kids with cerebral palsy have a harder time reaching for things, and their brain works differently when they try to do it quickly.
Methodology
The study involved 14 children with spastic CP and 14 matched controls performing reaching tasks with a robotic arm while their brain activity was monitored using fNIRS.
Limitations
The sample size was modest, and the study did not assess sub-group differences or collect data on eye movements and proprioception.
Participant Demographics
14 children with spastic CP aged 5-11 years and 14 typically developing controls matched for age, sex, and arm dominance.
