Insights
Early prediction of cerebral palsy (CP) is possible using fidgety movement assessment (FMA) and brain magnetic resonance imaging (MRI) in infants. Combining FMA and MRI offers high accuracy for diagnosing CP during the neuroplasticity period.
Area of Science:
- Pediatric Neurology
- Developmental Pediatrics
- Medical Imaging
Background:
- Early prediction of cerebral palsy (CP) is crucial for timely intervention during infant neuroplasticity.
- Fidgety movement assessment (FMA) and brain magnetic resonance imaging (MRI) are potential tools for early CP detection.
Purpose of the Study:
- To evaluate the predictive value of FMA and brain MRI, individually and in combination, for CP development.
- To assess the diagnostic accuracy of FMA and MRI in a clinical rehabilitation setting.
Main Methods:
- Retrospective observational study of 258 infants (March 2018 - September 2019).
- Infants underwent FMA and brain MRI at 9-20 weeks corrected age.
- Assessed diagnostic performance using AUC, sensitivity, specificity, and accuracy for CP prediction.
Main Results:
- Fifteen out of 258 infants developed CP.
- The combination of FMA and MRI demonstrated high diagnostic accuracy: 86.7% sensitivity, 98.4% specificity, and 97.7% accuracy.
- Combined FMA and MRI showed a significantly higher AUC (0.981) for predicting CP than FMA alone (0.893).
Conclusions:
- The combination of FMA and brain MRI provides a highly predictive tool for CP development in infants.
- This combined approach is valuable in clinical rehabilitation settings for early CP identification.
Background:
The early prediction of cerebral palsy (CP) could enable the follow-up of high-risk infants during the neuroplasticity period. This study aimed to explore the predictive value of fidgety movement assessment (FMA) and brain magnetic resonance imaging (MRI) for the development of CP in clinic rehabilitation setting.
Methods:
This retrospective observational study included infants who underwent FMA and brain MRI at age nine to 20 weeks at Children's Hospital, Zhejiang University School of Medicine, between March 2018 and September 2019. The area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy of FMA and MRI for predicting the development of CP were assessed.
Results:
A total of 258 infants (169 males, gestational age 37.4 ± 3.0 weeks, birth weight 2987.9 ± 757.1 g) were included. Fifteen children had CP after age two years. The diagnostic value of FMA and brain MRI combination showed 86.7% sensitivity (95% confidence interval [CI]: 58.4% to 97.7%), 98.4% specificity (95% CI: 95.6% to 99.5%), and 97.7% accuracy (95% CI: 95.0% to 99.1%); the combination diagnostic value also showed a significantly higher AUC for predicting CP after age two years than FMA alone (AUC: 0.981 vs 0.893, P = 0.013).
Conclusions:
The diagnostic value of FMA and brain MRI combination during infancy showed a high predictive value for CP development in clinical rehabilitation setting.
