Children with cerebral palsy (CP) show less efficient postural control but can adapt their movements when performing tasks. Their postural control improves when engaging in a secondary task, demonstrating system flexibility.
Area of Science:
- Neuroscience
- Biomechanics
- Developmental Pediatrics
Background:
- Children with cerebral palsy (CP) often exhibit impaired postural control.
- Understanding the adaptability of postural control in CP is crucial for rehabilitation.
Purpose of the Study:
- To investigate adaptive postural control in children with CP during a supra-postural task.
- To compare postural control dynamics and variability between children with CP and typically developing (TD) children.
Main Methods:
- Center of pressure (COP) dynamics (sample entropy) and variability (standard deviation) were measured.
- Participants included children with CP (n=30) and TD children.
- Postural control was assessed during quiet stance and a supra-postural task (balancing a marble in a tube).
Main Results:
- Children with CP showed greater COP irregularity and sway variability than TD children during quiet stance.
- These differences were reduced but remained statistically significant during the supra-postural task.
- The findings suggest that the postural control system in CP can adapt to task demands.
Conclusions:
- Despite underlying inefficiencies, children with CP demonstrate adaptive capacity in their postural control system.
- Supra-postural tasks can reveal flexibility in motor control despite CP-related impairments.
- These findings have implications for designing targeted motor interventions for children with CP.
