Insights
Children with spastic cerebral palsy exhibit poorer sitting posture control than typically developing peers. Objective measures like sway index and ratio effectively differentiate these groups, aiding in assessment.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Rehabilitation Science
Background:
- Cerebral palsy (CP) is a common neurodevelopmental disorder affecting motor control.
- Posture control in a sitting position is crucial for daily activities and functional independence.
- Quantitative assessment of sitting posture control in children with CP is essential for targeted interventions.
Purpose of the Study:
- To quantitatively compare sitting posture control between children with spastic cerebral palsy and typically developing children.
- To identify objective and sensitive indicators for assessing posture control deficits in spastic cerebral palsy.
Main Methods:
- Employed the Chatteex Balance System for quantitative evaluation.
- Assessed static and dynamic posture control in 20 children with spastic CP and 20 age/sex-matched controls.
- Measured sway distance, sway ratio, and sway index in sagittal and lateral directions.
Main Results:
- Children with spastic CP demonstrated significantly lower static and dynamic sway ratios.
- The spastic CP group exhibited a greater static sway index and dynamic lateral sway distance.
- A trend towards a greater dynamic sway index was observed in the spastic CP group, though not statistically significant.
Conclusions:
- Children with spastic cerebral palsy show significantly impaired sitting posture control compared to their typically developing peers.
- Sway index and sway ratio are reliable and sensitive quantitative measures for distinguishing children with cerebral palsy.
- Findings support the use of objective balance assessments for evaluating posture control in pediatric populations with CP.
Objective:
To quantitatively evaluate the difference of posture control in sitting position between children with spastic cerebral palsy and normal subjects.
Design:
Twenty children with spastic cerebral palsy who could sit independently and 20 age- and sex-matched normal children were enrolled. The Chatteex Balance System was used to evaluate static and dynamic posture control as the subjects were sitting on a bench. The sway distance in sagittal and lateral directions, sway ratio, and sway index in both the static and dynamic sitting positions were recorded by the Chatteex Balance System.
Results:
There was a significantly lower static and dynamic sway ratio and a greater static sway index and dynamic lateral sway distance in the study group. The dynamic sway index in the study group was greater than the index in the control group, although it did not reach statistical significance.
Conclusions:
Children with diplegic cerebral palsy did perform significantly worse in sitting posture control compared with normal subjects of similar chronological age. The sway index and sway ratio proved to be the objective and sensitive indicators that can be used to distinguish children with cerebral palsy from normal peer groups.
